Many health-conscious people are haunted by the idea that they “should” correct their posture. They fight a long-term, tedious war against self-imposed or careless crookedness, assuming it’s essential self-defense against common problems like neck pain, headaches, and especially low back pain. Is it all a wild goose chase? Are aches and pains caused by “poor posture” in the first place? Even if they are, is it actually possible to improve posture?
The ways that we sit and stand and walk are among the strongest of all habits. Changing posture may be as hard as quitting smoking or potato chips. So it had better be worth the effort!
After working as a massage therapist for many years,1 I became confident that poor posture is a “real” thing,2 a genuine source of partially preventable physical stress and therefore probably a factor in chronic pain, mostly later in life. But it’s not a straightforward business, this posture stuff. There aren’t many “easy wins” for people here. And there’s plenty of potential to waste time and money — or even get hurt.3
Delving deeper into the topic as a journalist — much deeper than I ever did as a massage therapist, studying the scientific literature and learning more from countless readers and experts — I have developed many reasonable doubts about posture’s importance and the value of trying to change it. I have come to believe that many healthcare professionals pathologize posture, exaggerating its importance to justify costly therapy (all with good intentions, of course).
This doorstopper of an article thoroughly explores strategies for postural improvement that may be helpful, but I also explain why the idea of “poor posture” is mostly much ado about nothing — a problem in theory, but only a minor one in practice. If your main issue is stubborn aches and pains, there are probably much better ways to spend your time than trying to improve your posture.
Posture is not a position, but a constantly shifting pattern of reflexes, habits, and adaptive responses to anything that challenges your ability to stay upright and functional, such as:
- Gravity, of course!
- Awkward working conditions, which may be unavoidable (nurses must lift patients!), and/or self-inflicted and correctable (lousy ergonomics).
- Abnormal anatomy.
- Athletic challenges.
If you start to tip over, or lose the stability you need for a task, postural reflexes kick in and engage muscles to pull you into a more or less upright and/or functional position again. The biological systems and tricks that keep us upright are nifty, and surprisingly poorly understood.4
Posture is the embodiment of your comfort zone. At worst, it can be like a cage.
Posture is also body more than the sum of those parts, more than “just” a collection of righting and stabilizing reflexes — it is the way you live, the shape of your flexible “container,” a physical manifestation of your comfort zone. We habitually hold ourselves and move in ways that serve social and emotional needs, or avoid clashing with them. It is a major part of body language. Posture can be submissive or dominant, happy or sad, brave or fearful, apathetic or uptight.
The challenges and rewards of trying to change posture are not just musculoskeletal: it can be a profound personal process. Patterns and behaviours that lead to trouble are usually strong.5 This article does not get too “deep” and mostly sticks to the musculoskeletal issues and the relationship between posture and pain, but the psychology of posture also matters.

One of the best-known specific examples of allegedly poor posture is “Upper-Crossed Syndrome” (UCS). It sounds impressively technical. Named by a Czech doctor and researcher, Vladimir Janda, it is the apex of clinical storytelling about posture in therapy culture, and the prototypical “muscle imbalance” theory. No idea about bad posture has ever been both this popular and “advanced.” It is the backbone of conventional wisdom about posture. And what is it?
Basically just slouching.
Head and shoulders forward, mostly, but UCS comes with some complicated assumptions about its causes and consequences, like your muscles dysfunctional ship’s rigging: some are weak and loose (“inhibited”), while others are too strong and tight (“facilitated”). Viewed from the side, you can draw diagonal lines between these groups that cross. (There’s a Lower-Crossed Syndrome as well, but it’s much less famous.)
Dr. Janda was a pioneer. He did good work with the information he had at the time. But he was probably mostly wrong about UCS,6 and the rest of the article substantiates this in many ways. But here’s one quick, fresh, solid example…
A good quality 2021 study of hundreds of young folks showed that they actually got less neck pain over five years if they had a classic UCS posture.7 Less! It was good for them. Conversely, an erect posture was linked to more neck pain. The difference wasn’t huge, but it was a difference in exactly the wrong direction for validating Dr. Janda’s idea.
Muscle imbalance ideas like UCS have not done well over the last couple decades. Jason Silvernail, Doctor of Physical Therapy, comments: “There is almost no data to support these ideas and to my knowledge there never has been.” Inhibition and facilitation sound technical and specific, but they aren’t: they are pseudo-jargon, words for things that are actually poorly understood and defined. Research has relentlessly shown that professionals have trouble agreeing on muscle balance. The “tightness” of muscles doesn’t seem to have much to do with their strength, or with pain, or really anything that anyone can actually work with. If certain muscles were actually weak in everyone exhibiting a certain posture, and those people tended to have certain problems, then it would make sense to try to strengthen those muscles specifically. But they aren’t, and they don’t, so it doesn’t. Treating people as if they have UCS — with targeted stretching, strengthening, and massage, say — doesn’t work any better than generally getting more exercise.
Nor is any of this surprising given where the science has gone. It has become clear that the “behaviour” and condition of individual muscles is mostly trivial compared to the potent role of the central nervous system as the dictator of almost everything about both function and sensation. In short, it’s not messy muscle function that makes people slump and hurt — it’s a brain thing, and UCS is an effect instead of a cause.
Or UCS is just a clinical fantasy: it’s most likely that there just isn’t a UCS pattern at all, no “cross” of weak/tight muscles. A bogus narrative. There is just a common posture, plus the panoply of human aches and pains that come and go like aurora borealis, most of which still cannot be specifically explained and probably never will be. The fundamental problems of troubleshooting chronic pain is that there are so many possible causes and chronic pain isn’t a reliable, informative signal.
UCS is just a good story Dr. Janda told in the absence of good data. It seemed like a good idea at the time, but it has become quite obsolete. So why is this vision of poor posture still so popular? Jason Silvernail again:
“It’s accessible to a wide variety of practitioners. Since it involves muscular assessment, everyone from physicians to personal trainers to physical therapists, chiropractors, athletic trainers, massage therapists and strength coaches could use this approach with their patients or clients. Both clinicians (physicians, physical therapists, chiropractors, athletic trainers) and fitness and service professionals (personal trainers, strength coaches, massage therapists). Those with rigorous academic education at doctoral or postgraduate level (physicians, physical therapists), those with college education (athletic trainers, strength coaches, some trainers) and those with trade school or certification training (personal trainers, massage therapists). Huge numbers of different people in different fields could use this. A marketing dream. It provides a simple solution to a complex problem that leverages deeply embedded cultural ideas that are far more powerful than scientific data.
“That’s why these crossed syndrome type things make no sense whatsoever but are not going away any time soon. People will be talking about this brilliant insight for another 50-odd years. I wonder if Janda would [facepalm] if he heard how people were unable to move beyond this idea, and had more fidelity to this particular product/idea than to the process he advocated.”
This is what skeptics mean when they say that there is no such thing as bad posture — and I completely agree with the spirit of that position. But there is also more to “poor posture” than UCS. Or perhaps I should say there’s less to it …

My definition of poor posture is simple (but took me many tries to settle on):
Poor posture is any habitual, self-imposed positioning that causes physical stress, especially coping poorly with postural challenges.
A postural challenge is anything that makes it harder to maintain a comfortable posture, such as “work.” A major source of postural challenges in all our lives is awkward tool use, also known as crappy ergonomics.
Sitting for hours with your knees tucked sharply under your chair is a good basic example of a poor posture. No one has to sit like that. The chair isn’t forcing it. It’s an entirely optional arrangement of limbs. And yet it is an actual hazard to kneecaps8 — a completely avoidable hazard, which most people fail to avoid because they just don’t know how knees work.
If anyone ever tells you there’s no such thing as poor posture — a popular skeptical perspective — that example is a fine rebuttal. And there are certainly others.9 How much poor posture actually matters on average — not very much, probably — but for sure there is such a thing.
What about postural laziness? Specifically what most people actually mean when they think of poor posture, thanks to the Puritans,10 is slouching. The avoidance of postural challenges leads over time to poor postural fitness. In other words, if you avoid postural challenges enough, eventually you’ll have trouble coping with them when you have to … and so we’re back to the first definition.
Comic by MimiAndEunice.com, which is a lovely place.
Other than “laziness,” why would anyone respond ineffectively to life’s postural challenges? Weakness, mood, pain, hang-ups, fatigue, fear, stress, and more.
Sometimes an effective response to a postural challenge is almost impossible, and that really gets you off the poor posture hook. Many seemingly poor postures are actually just compromises, adaptations to unavoidable stresses. Posture zealots forget this. If the cause of a posture is baked into your anatomy, trying to change it is going to hurt more than help, or it will just be futile. If your posture is caused by adaptation to a shortened leg bone dating back to a motorcycle accident twenty years ago, you aren’t going to have much success changing your posture. The context of posture is important! As often as not, what seems like a poor posture is just a functional adaptation, and sneering at it is ridiculous.
For instance, an old man may walk stooped over because he has spinal stenosis and it really hurts to stand up straight. There’s nothing lazy about his stooping. The stooping is creating postural stress, but it’s the lesser of two evils, and it’s the same postural compromise that everyone with painful stenosis chooses. But for a young man, presumably without stenotic back pain, the same posture would be really strange: an unnecessary stress, certainly “poor” and worth fixing, if possible.
Of course, for the most part young men do not stoop like old men …

Physical therapists think that posture matters. In a 2019 study, several hundred of them were asked to rate the importance of optimal sitting and standing posture, and 65% considered it “very” important (and another 28% ranked it just below that).11 They did not entirely agree on what those postures are, which is a bit embarrassing, but they gave similar justifications for them regardless, which is even more embarrassing.
These professional opinions do not appear to be evidence-based.
People probably naturally avoid the most ineffective responses to most significant postural challenges. Homo sapiens is allergic to physical stress. We prefer to be comfy. And although postural laziness might seem obviously evil,12 people also naturally tend to keep up their postural fitness for the things they care about (if you like playing sports, you play them).
The “problem” of poor posture is mostly minor and self-limiting. The worst problems are avoided naturally, instinctively. The postural fitness that matters the most is taken care of almost automatically, and what remains is relatively trivial.
Doing it the hard way!
How long do you think you could work like this without regretting it?
That said, we can also be surprisingly self-defeating! In fact, this seems to be a weird feature of “higher” intelligence:13 we are prone to doing things the hard way and failing to avoid unnecessary stresses. So we probably do make some postural mistakes and develop bad habits, because we are careless, or because our big brains place too much emphasis other priorities, or because don’t even know that we’re doing something stressful (like the knees-tucked-under-the-chair example). Fortunately, the scientific evidence strongly suggests that doing things “the hard way,” posturally speaking, is probably not all that harmful even when we make that mistake. Here are some interesting examples …
- A leg length difference is portrayed by many therapists, especially chiropractors and massage therapists, as a serious postural problem that inevitably causes pain. And yet it’s been proven that people with significant leg length differences suffer from no more back pain than anyone else.14 (Not that minor differences can even be reliably diagnosed in the first place.15)
- Athletes with large differences in the mass of their low back and hip muscles — exactly the kind of “imbalance” that is targeted for repair by therapists everywhere — don’t actually get hurt any more often than players with more evenly distributed muscle mass.16
- Or consider this study of coordination exercises for the neck: it showed that the exercises had exactly the intended effect on coordination and posture … but no effect on neck pain at all.17 What’s the point of posture exercise if it doesn’t actually help with pain problems? Maybe none! That’s the point.
All of this flies in the face of “posturology”
Posturology is the cheesy, popular term for the mostly made-up “discipline” of studying the relationship between posture and pain, and even between posture and diseases.18 Posturologists (I can barely type that word with a straight face) tend to assume their own conclusion: they assume that poor posture causes pain, and then look for confirmation of that. And so there are many, many scientific papers that seem to present evidence of a connection between posture and pain, but most of them suck — here’s a nice appalling example19 — and “posturology” is mostly a pseudoscientific research backwater. If posturology research was better quality, we might actually learn something from it. But most of it must be chucked or, at best, taken with a huge grain of salt.
Posture is only one of many hypothetical factors that contribute to pain problems, but in many cases it probably isn’t contributing at all. This is obvious from a simple observation: there are a lot of people with nice posture who are in terrible pain, and also many people with lousy posture but no pain.
The most stereotypical poor posture of them all — a hunched upper back, with the shoulders rolled forward — is widely assumed to be a cause of shoulder and back pain … but the assumption is almost certainly wrong. This has been studied to death (for a posture problem). According to the collective results of ten different experiments it is almost certainly not a cause of shoulder pain.20 A large 1994 study of kyphosis in older women found no connection either: not even the 10% with the worst kyphosis had “substantial chronic back pain, disability, or poor health.”21 There’s just nothing there. Hunchers are not wrecking their shoulders and backs.
More exotically, I had a truly scoliotic patient, an elderly woman with a blatant S-curve in her spine that she has had since she was a child. Despite this obvious major source of postural stress, she suffered nothing worse than annoying back stiffness in her whole life. Another much younger woman, but with extreme scoliosis, was also amazingly pain-free.22 Meanwhile, in my ten-year career as a massage therapist, I had a steady stream of people through my office with severe back pain … and perfectly ordinary posture. What’s the difference between these patients? Probably not their posture.
Research has shown that abnormal curvature of the cervical spine is actually not closely associated with neck pain.
Another good example: a client with a pronounced torticollis (“wry neck”), and who was even little deformed by it.23 But, once again, this middle-aged patient suffers from no more than irritating chronic discomfort, while many people with much more normal head posture are just about driven nuts by neck pain (including yours truly, which is why I wrote a book about neck pain).
There are many better-documented stories like this, like the case of a serious traumatic cervical dislocation reported in New England Journal of Medicine in 2010, notable for being mostly asymptomatic: just torticollis and stiffness, but no pain, weakness, or altered sensation. That such a serious injury could ever have that little impact on a person is quite interesting, and it puts the hazard of “poor posture” in some perspective.24 Research has shown that abnormal curvature of the cervical spine is not closely associated with neck pain25 and is probably not clinically significant.26
A larger 2016 study of 1100 Australian teenagers showed that there was no correlation — none at all — between their neck posture and neck pain, contrary to all the fear-mongering we’ve heard about “text neck” in the last couple years.27 A similar 2018 study of Brazilian youths came to the same conclusion.28 For balance, I’ll acknowledge there are studies that say otherwise29 … but mostly just crappy studies in my opinion,30 and regardless they do not remotely prove that abnormal curvature actually causes pain.31
In general, the story is the same for the low back — the other posture hot zone. For instance, you could hardly ask for a more clichéd notion about posture than the idea that slouching is bad for your back. Teens slouch a lot, and they do get back pain (though much less than adults do), so if posture is an important factor in back pain, it shouldn’t be too hard to find a connection. But a biggish 2011 study did not: “a greater degree of slump in sitting was only weakly associated with adolescent back pain.”32 No smoking gun there.
Physical therapists tend to make too much fuss over extremely subtle postural “problems,” which match up even more poorly with pain than the obvious postural problems.33 The popularity of such theories generally suggests to me that posture is often a therapeutic red herring. Both its importance and its “fixability” are routinely overestimated by professionals in a self-serving way.
And yet that doesn’t mean there isn’t still something of interest going on. Health problems don’t have to be severe to be of interest.

I enjoy “pathologizing” posture. It gives me a sense of purpose.
Les Glennie, Registered Massage Therapist (yes, tongue-in-cheek)
I once sat at a bar with my wife and spent about twenty minutes leaning to my right while we ate and talked, an awkward position that got uncomfortable fast. I fidgeted for a few minutes before I realized what was going on, but it was too late: my low right back had already “cramped up.” It was painful for days, and a slowly fading annoyance for weeks after that.
People with less vulnerability to body pain, especially younger people, do not relate well to that kind of story. They may be inclined to underestimate the severity of the pain, dismiss the timing as a coincidence, or to call it a problem with vulnerability rather than a postural problem. (And they may be right! More on this soon.) But it’s quite real for a great many people, especially older ones.
The existence of this kind of situation was shown in a large, interesting study of triggers for back pain — what were people doing when they were struck by an episode of acute back pain, basically.34 The results emphasized both that posture isn’t a major risk factor for back pain and that it isn’t nothing either. By far the two biggest risk factors both had something to do with temporary awkward postures:
- Being “distracted” was by far the biggest risk:
patients were twenty-five times more likely to be distracted “during an activity or task” right before an episode of back pain than at other timesin the preceding couple days. Although the study didn’t specifically establish what is meant by “distraction,” I suspect those stories are much like the one I told above: the problem was not so much that I was in an awkward posture (which happens all the time), but that I was distracted and didn’t notice the awkwardness of my positioning until it was too late.
- Although a distant second to distraction, “awkward posture” topped the list of more specific examples of “manual tasks” that were also risky, and it was notably a greater risk factor than heavy/awkward lifting (which in turn was actually one of the lowest risks, and got significantly lower with age — not what most people would predict).
Everyone will be happy to hear that sexual intercourse was not a common back pain trigger, though I imagine it depends on how you do it.
So hopefully that makes it obvious that I’m not throwing the posture baby out with the bathwater. It’s clearly one of the many factors involved in body pain, even if it’s also clear that it’s not alone, and not dominant. I’ve seen countless cases where relatively obvious and avoidable postural and ergonomic stresses did seem to cause pain — and in many cases that pain was relieved easily enough just by avoiding obviously poor posture. On the other hand, most such cases actually involved only an imposed postural stress, as opposed to “poor posture.” This is a constant point of confusion and really important to sort out …
GO TO TOP • CONTENTS • NOTES
There is a big difference between “poor posture” and “postural stress,” but the distinction seems to be absent from most discussions of posture and ergonomics.
A postural stress is a challenge to your posture that’s imposed on you, as opposed to something you’re doing to yourself out of laziness. It’s situational, as opposed to being the result of a bad habit. Some examples of postural stresses:
- trying to sleep where it’s impossible to do so without putting your neck in an awkward position, like a plane or car seat
- a cashier whose till is positioned a little too far away, causing chronic reaching
- uncorrected vision problems, forcing routine squinting and awkward head repositioning
- a drywall installer who virtually lives in constant neck extension
- a nurse who must constantly stoop over patients, and perform extremely awkward patient lifts
- a writer who must type incessantly — not a bad habit, just something that some of us have to do!
But sometimes you are the source of postural stress. When the challenge is self-imposed by your own positioning and readily preventable, that is poor posture — it’s just relatively rare, something we easily avoid most of the time.
There is some overlap between poor posture and postural stress, of course. Carrying a heavy backpack slung over one shoulder is a good example: it’s technically a self-imposed inefficient use of the tool, not an inherent flaw in the tool, and yet it’s also often convenient and sometimes temporarily necessary.
Many postural stresses can be avoided if you recognize the problem, but
I recall a case of a man with truly awful chronic upper back pain and a nasty computer workstation. I remember my amazement as he described it to me. He was barely aware of it being a problem — I had to tease him about it, it was so absurd — but once the problem was pointed out, he made several easy improvements … and that was the end of his problem. I find it hard to think of that case as a “posture” case.
Another good example: the fiddle player who developed terrible pain in his shoulder. Incredibly, he did not tell me that he was a serious fiddle player, but just described himself as a shoulder pain patient and didn’t mention the fiddle at all. It was only after carefully quizzing him that I discovered he was practicing the fiddle for hours every day with his shoulder intensely hunched up, as fiddlers do. If he stopped playing, the pain would fade away over a few days. If he resumed, it would flare back up. He had been doing this for years, but didn’t think to mention any of that to me. And what a terrible dilemma: a clear postural stress required by a beloved activity! Maybe he didn’t mention the fiddle connection because he didn’t want that to be the problem. I’m sure he didn’t want quitting to be the solution. That guy loved playing the fiddle.
Ergonomics is the science of arranging or designing things for efficient use, specifically to avoid postural stress. Unfortunately, ergonomics is usually interpreted unimaginatively, with the result that most people think that ergonomics is just about choosing office chairs and changing the tilt on your keyboard. Lots of things can indeed be said about office chairs and the tilt of your keyboard — but it’s only the tip of the ergonomics iceberg.

We live in a gravity field that never quits: day in, day out, it pulls us unwaveringly towards the center of the earth. If we are chronically a little bit crooked, some muscle somewhere is going to have to work more than its fair share to keep us upright. Try this yourself: see how long you can stand leaning a few degrees to one side. Exaggerated imbalance gets uncomfortable fast. And subtle imbalance presumably gets uncomfortable slowly, for at least some people. And the discomfort often outlasts the stress. Why?
No one really knows, but here’s a theory:
Muscle functions painlessly and well under most conditions — it’s a high-performance tissue. It can get surprisingly sensitive, though, usually in fairly well-defined patches, which are popularly called muscle “knots” or trigger points. I have written a lot about this mysterious phenomenon (including my doubts that it’s even muscular35 — but at any rate it certainly is good at seeming muscular). It’s not clear exactly what biological conditions cause this sensitivity, and it’s notoriously unpredictable. But there is one good method of inducing trigger point pain: awkward postures.
Trigger points seem to be closely associated with a wide variety of other common pain problems. This surprisingly ordinary condition may even be the source many of the (non-arthritic) aches and pains suffered by the human race, especially low back pain.
If poor posture contributes to the formation of knots in tired muscles — which is far from proven, but it’s a reasonable hypothesis — then this might be the chief risk of poor posture, and it might be a good idea to try to improve it.

If it’s so easy to induce muscle sensitivity by fighting gravity and adopting awkward postures, why aren’t we all in agony all the time? Lots of people live in gravity! (Everyone but these lucky people.) And many people frequently have awkward postures, but never have pain problems.
So why me? Why so many others? And is poor posture really the problem, or are some people just excessively vulnerable? It’s probably both, but I’m skeptical about posture as the direct cause of anything. The range of asymmetry that people can tolerate is probably quite wide, highly variable, and generally narrower with age,36 but the average healthy person can probably easily tolerate “poor posture” with no problem. And if poor posture can’t really hurt a healthy person, it’s not much of a demon, is it?
On the other hand, more vulnerable people, people who get pain from trivial postural stress — people like me — do not have a posture problem so much as we have a pain problem. A vulnerability. The greater the vulnerability, the more it’s about the vulnerability and not the posture — awkward postures are just another thing that triggers pain (even if we are quite careful). It doesn’t really seem like posture is what needs troubleshooting there.
I’m a bit doubtful that anyone is wandering around in pain as they age because they were sloppy with their posture in the past. It's possible, but I prefer this story: vulnerability increases with age, and we start to notice that postural challenges we once coped with easily are starting to get tricky. And almost everyone gets there eventually. The “worst” postures become problematic sooner, of course, but I doubt they are the cause — just the messenger, and the message is, “You don’t handle physical stresses like you used to.”
"Inflammaging" is the inexorable increase in systemic inflammation as we age, strongly associated with poor fitness, but there are probably many other causes as well. It is the most ubiquitous of many causes of vulnerability to chronic pain all of which seem more likely to cause trouble than posture.

All tissues wear out when the stress on them exceeds their capacity to heal and adapt. Degenerative arthritis is a universal human condition — everybody develops it eventually, to some degree. It seems like a super reasonable guess that tissues wear out unevenly when they are loaded unevenly — just like shoes wear out unevenly in proportion to how uneven your gait is.37 Some people develop arthritis much more quickly than others, and poor posture certainly is a likely suspect.
Plenty of research does confirm a logical connection between posture and arthritis. For instance, a 2012 study of knee arthritis — an ideal place to look38 — showed that people who already have arthritic knees are bigger leaners, and their gait is “consistently different” than people with healthy knees, and they probably weren’t walking differently because of pain. That is, the crookedness probably caused the arthritic pain, as opposed to arthritis just making them walk crookedly.39
On the other hand, we have all the evidence presented earlier — and much more — that janky biomechanics just generally don’t match up very well with chronic pain. Arthritis itself is often surprisingly painless. Again with the knee, one of the most popular theories in musculoskeletal medicine is that uneven control of the kneecap — due to abnormal anatomy and/or posture — will cause the cartilage on the underside of the kneecap to degenerate painfully, which in turn causes a common kind of knee pain, patellofemoral syndrome. And yet, in fact, degeneration of that patellar cartilage can be painless.40
I could go back and forth with the research all day, but the messiness of the evidence is the answer. Poor posture probably can hasten joint decay, but it’s not a major factor.

Poor posture can get us into an emotional rut. This is a more subtle postural problem: the “comfort zone” problem. (I promised not to spend too much time on it, but it does get a section.)
It’s relatively obvious that posture is shaped by mood and all kinds of other social and emotional factors. But this double-edged sword might cut the other way, too: posture may, to a modest extent, actually create and reinforce emotional states. Yes, I’m talking about “power posing” — a notoriously over-hyped idea.41 However, follow-up research has been solid enough that I feel comfortable concluding that a confident posture can influence our emotions at least a little.42 It may not be a huge effect, but it’s probably there.
If posture can influence emotions, then it’s no surprise that it could also change pain sensitivity, and there is some evidence of that too.43 So, here’s a free, easy pain relief tip at least partially based on some science: Stand tall! Assume a bold posture, a “power” posture. Or, as a mentor of mine liked to describe that posture: “Tits up!” It might actually reduce pain — a little. A temporary reduction in sensitivity is hardly a cure for chronic pain, if it works at all, but trying certainly isn’t going to do any harm.
Emotions, posture, and pain sensitivity probably do all influence each other to some degree. Most self-limiting behaviours have both postural effects and causes. The classic example is depression: a depressed person will adopt a distinctively depressed posture, which can be quite obvious to everyone around them.44 Less obviously, a depressed posture may also generate depression. Happy people who “try it on” will actually start to feel sad! And, conversely, sad people who adopt happy postures and expressions will feel a little better.
Cool, eh? Physicality and emotionality are probably not cleanly distinct!
The blending with physicality is interesting, but the emotional dimensions of posture are interesting all by themselves. Above I defined a poor posture as an “unnecessary and problematic pattern.” That pattern may be emotionally problematic. It can both express emotional hangups and actually cause and reinforce them. Posture can be a self-limiting behaviour, something that actually keeps you in a poor state of mind.
We hold ourselves in a certain ways because they reflect our comfort with the positions — and our discomfort with other positions, such as “holding our head high.” Just as we eat comfort food to our detriment, we may also slouch comfortably to our detriment, constantly projecting to the world (and creating the reality) that we aren’t ready, or we’re depressed, or sullen, or bored with life, or whatever it may be. When we leave poor posture unchallenged, we also fail to leave our emotional comfort zone, which is generally necessary for personal growth. See Pain Relief from Personal Growth: Treating tough pain problems with the pursuit of emotional intelligence, life balance, and peacefulness.
Although it’s all a bit flaky and murky, I actually believe that posture’s relevance to emotional state and pain sensitivity may be the best reason to experiment with changing posture.
To pretend to be calm is to be calm, in a way.

Popular thinking about posture is dominated by the ideas of straightness and alignment. It permeates even guru-level rhetoric about posture. (And just the fact that there are “posture gurus” is rather interesting, isn’t it? Why? They are gods of the gaps.45) Many posture gurus will talk about something like “an efficient response to gravity” with confidence, which is really just a fancy way of saying “straight and aligned.” I do not believe that anyone actually knows what an “efficient” posture is, and it is not necessarily defined only by straightness or precise verticality.
We are the only species on planet Earth that routinely stands upright, and there are many reasons to believe that our erectness is a biological compromise of questionable value and comfort. Scientists are not sure why we ever stood up in the first place, and there is no evidence today that standing up especially straight is necessarily the way to go … or has any survival benefit … or, if it does, that it will necessarily be comfortable …
Consider your spine. It is essentially the same spine owned by every mammal in the world. And nearly all of those mammals carry their spine horizontally. So where did we ever get the idea that we should stack our vertebrae one on top of the other?
There is no obvious sign that our anatomy has significantly or effectively adapted to the upright position. For instance, the connective tissues of our abdomen are still similar to those of the quadrupeds: they are generally suited to holding our guts suspended below our horizontal lumbar spines, not for holding them like a sack tied to a vertical pole.
So I reject the “stand-up-straight” definition of good posture. Good posture is not necessarily about straightness! And yet it is essentially the only widely used definition, even by people with supposedly very sophisticated opinions about posture. You may think I’m blowing the guru-thing out of proportion, but it is literally true that there have been successful entrepreneurial empires based mainly on trademarking and selling the importance of straightness and a method of getting there and staying straight, and then there are probably ten times more successul businesses that may not be devoted to posture straightening in particular, but use it as one of their founding assumptions or marketing bullet points.
I am not saying we shouldn’t stand up straight. I am just pointing out — again, in yet another way — the uncertainties associated with any idea about posture, even this most basic and universal one. There is good reason to doubt anyone who claims to know that good posture is a matter of being well-aligned.

A definition of good posture is necessarily much less precise than defining a poor posture, because it depends on what you want, and it’s essentially impossible to measure success. So here are a couple almost philosophical suggestions. I’ll let Morgan Freeman start it off …
Your best posture is your next posture.
A good posture is probably “dynamic,” emphasizing change and movement. Keeping active, frequently changing our posture, and experimenting with new ways of moving through the world are probably good responses to the uncertainties of posture. It’s the same in spirit as the nutritional advice to eat a varied diet.46
Most people lead overly sedentary lives — 6–8 hours per day of inactivity, an hour more per day in 2018 than 200847 — and are also overly consistent in their limited physical activity; that is, even people active at work are often active in only one way, and they need variety in their movement. More movement — not any particular position, but more positions — is definitely a safe bet and a good start on a good posture.
A variety of postural behaviours will also help to strike a balance between the path of least resistance and obsessive and excessive effort, neither lazy nor overzealous. Do not stray too far from your comfort zone, but do not linger there either.
The odds are lousy that I actually said something attributed to me.

Much of what we perceive as “poor posture” is the result of biological adaption over decades and is unlikely to change without a truly heroic effort — and perhaps not even then. In principle, humans can adapt to almost anything — in fact, it’s the law.48 However, the same principle dictates that change is slow and difficult.
Wear high heels for many years, and your calves will actually shorten,49 and it’s not clear how easily that can be undone. On the other hand, grow up climbing trees like the Twa people of Africa and you will earn amazingly limber calves that allow your ankles to bend halfway (45˚) to the shin50 — two to four times greater than the average urban person! (A good video of this flexibility has unfortunately disappeared from YouTube.)
“Squatting like a baby” is a faddish fitness goal — and hopelessly unrealistic for most people. But if you grow up squatting like the Hadza bushmen, it’s no problem!
As Todd Hargrove puts it, not only do these people squat like a baby, “they squat better than a baby.”
They maintained all the mobility they had as babies, but added strength, stability and skill. They never stretch, never do yoga or pilates, never engage in any corrective exercise, yet they all move effortlessly in and out of positions that most Westerners cannot even get into.
Which sounds great. But don’t think for a minute that the Twa and the Hadza don’t have their own costs and consequences for the stresses they’ve adapted so beautifully to. Everything in biology involves trade-offs.
Many adaptations are almost certainly irreversible—or so difficult that they might as well be. A child can adapt in ways that are possible only in the plasticity of a rapidly growing body, and for the adult to try to undo it is like trying to straighten wood that was once artfully bent with steam. Other changes may occur only over vast spans of time, or because of variables we have little or no control over. The result is that some adult “postures” are simply impossible to change — we really do get locked in.
And yet we can change. Stretch actually can increase flexibility, with a lot of work (more on this below), for whatever it is worth. For the office worker who feels locked into a typist’s hunch — I know I do, as I type this — isn’t it worth at least trying to break out? Is the near futility of it all the more reason to at least make the effort? Perhaps it is.

There’s no basis for “shoulding” when it comes to posture. If the only reason you want to change your posture is on principle, I don’t recommend it. It’s not worth the trouble. You are not a good candidate for this process. There are probably a hundred more useful things you could do with your time.
The cure can turn out to be worse than the disease. A bad postural habit is not unlike an addiction. Trying to live with better posture may cause more problems, or be more uncomfortable, than whatever it was that drove you to try to improve your posture in the first place.
In a short article for The Guardian, Oliver Burkeman describes what it was like to switch to a special chair that “resembles a saddle, so instead of slouching, you perch. Or that’s the idea; in reality, it’s just rather uncomfortable. After 40 minutes, it’s extremely uncomfortable.”51 Change and challenge can be uncomfortable, and the payoff is uncertain. If Mr. Burkeman were to keep that up constantly for a decade, he might “toughen up” and be a better man for it, or he might find it a wearisome strain with no clear point! Hard to call.
However, if you are driven to the idea of postural transformation because of aches and pains, you may be quite motivated by the hope of a partial solution, and the side-effects of challenging new habits may be more worthwhile. You should probably try it, and keep it up for a while to give it an adequate chance, or even just for the sake of experiment.
Try to stay interested in the challenge for at least a month. Watch and wait patiently for new developments. It took me a good six months to learn how to stop sleeping face down … but now I can’t imagine going back. People who quit trying to change their posture after a week, or even after a month, have not learned much — except that they aren’t very good at it.
Be persistent and give it a fair chance. And then, if the first honest attempt doesn’t work? Give up.
What if you give postural change a fair chance, and there are no obvious benefits? What if you can’t really tell if you’ve achieved anything? What if you still seem to be crooked? Or what if you look straighter in the mirror, but it makes no difference to how you feel?
Definitely … give up.
I am all for trying anything once, and I think postural exercise is worth a shot if you think it might be connected to a pain problem. However, if a reasonable effort fails, I do not recommend a repeat performance. Once again, there are many better things you can do with your time — not just better things in general, but better things you can do to try to solve a pain problem.
There are simply too many problems, too many questions about posture’s relevance to pain. It’s worth trying to work with posture — but it’s not worth trying a lot.

Irregularity is to be expected in any biological form. Body parts are not interchangeable legos or Ikea furniture pieces made by factory molds. Wonkiness and asymmetry are part of the plan.
Playing With Movement, by Todd Hargrove, p. 169
In the rest of the article, I will review some approaches to improving posture, mostly defined as “increasing postural fitness.” Whatever your approach, I recommend choosing clear, functional goals and/or solving specific problems. Rather than shooting for “good” posture, think mostly in terms of postural fitness and ask yourself: what do you want to be posturally fit for?
The example of “flexibility” is instructive: many people have a stretching habit with the specific goal of being more flexible, but they literally can’t explain why they need to be more flexible. Or, if they do, the need is trumped up, even ridiculous.52 Athletes especially tend to exaggerate their need for flexibility.53 Most people don’t need to be more than a tiny bit more flexible than they already are, if that.
Similarly, most people do not need to be posturally fit for activities that they will never actually do. You don’t need to be able to balance on a tightrope unless you plan to work for a circus. Choose goals that make sense for you. In general, goals for postural fitness are almost indistinguishable from general fitness.
The seemingly technical challenge of changing postural habits is nothing of the sort: it’s almost entirely in the realm of art and faith, not science. Measures of success are primarily subjective. I have witnessed and personally tried many tactics for changing postural habits. There are no rules, no system to which you should devote your life, no right way to do it.
But there’s probably a wrong way!
Trying to force yourself to earnestly sit or stand up straight is so ineffective and pointless that I wouldn’t even bring it up, except that … it’s actually the default approach. This is what most people do.
When people decide that they “really need to work on their posture,” they usually don’t have any clear idea what they intend to do. Most people who worry about their posture go through episodes of trying — in no particular way, just mentally straining until their discipline fades.
Posture is the product of spinal reflexes and additional tweaking by your brain, all of which occurs — as it must — without the involvement of conscious attention. While you can always exert conscious control over your posture, you will always revert to the unconscious and reflex-controlled pattern the second your mind wanders. Consciousness is really just a thin scum on top of everything else the brain does.
If you are disciplined enough, you can sustain a posture long enough that the habitual, unconscious behaviour begins to change. But such discipline may have a price that not many people want to pay. To the extent that this ever succeeds, it tends to produce rigid, artificial postures — a caricature of posture, an imitation of good posture.54

Some problems will make it particularly difficult to improve your posture. It’s a good idea to try to solve them first … if you can. Obviously in many cases it won’t be easy, or even possible.
- Fatigue, especially from insomnia. Most insomnia is behavioural and treatable, even if it seems extremely severe and stubborn. I speak from painful personal experience. Treating insomnia is the highest priority for this challenge (and practically all others).
- Pain, especially if it is actually caused by poor posture. A lot of unexplained and chronic body pain is untreatable. But some is. Common muscle pain is unpredictable, but often responsive to nearly any kind of fresh sensory input, like massage or stretching — so it’s certainly worth trying to address common aches and pains in this way before trying to improve posture.
- Mood disorders are a major barrier to postural change. I am not a mental health professional, and this is not the place to recommend any solutions for those problems. However, I have recovered (and stayed recovered) from severe depression — so I can at least say with confidence that it’s possible and relevant.
- A job with significant postural stress. By no means should everyone with a physically demanding job quit so that they can work on their posture. However, if you believe posture is an important issue for you and you have a job that makes it difficult, then you should certainly consider a change.
Doubtless there are other examples, but you get the idea: make working on posture easier. Imagine how hard it would be for someone with all of these problems: a tired, hurtin’, depressed person with a job leaning over a conveyor belt for several hours per day is probably going to have a really hard time changing postures.

That might sound pretty weird to a lot of people — okay, it is kind of weird — but you don’t have to be obvious about it. No one has to know that you’re dramatizing anything. For instance, if you find it hard to lift your chest, lift your heart instead: walk down the street pretending to be three times more confident than you are (act “as if”) and watch what happens to your chest. If your back is uncomfortably curved (perhaps an excessive lordosis), then “walk like a dinosaur” — pretend you have an enormous, heavy, swaying tail as you walk.55 And so on.
Todd Hargove of Better Movement:
It is usually quite obvious to people that changing their thoughts might be a good way to change their mood. For example, people might try to combat sadness or depression by “thinking happy thoughts.” Another possible approach would be to “move happy moves.”

Interrupt or remind yourself to pay attention to your goal using timers and buzzers or whatever works. This can be very useful for increasing body awareness. Similar tricks can be played with signs, alarms, or oddly placed objects around your home or office. This might seem suspiciously similar to trying to improve your posture by force of will, but my suggestion here is more just about triggering self-awareness of a specific issue. For instance, if your specific postural goal is to reduce headache frequency and severity by breaking a bad habit of sitting on the edge of your chair and leaning in too close to a computer screen … then it may be useful to remind yourself — frequently — about the problem.

Some people will relate best to an exercise ritual — strive for your goal repeatedly or continuously until it gets easier. Repetition is required for most kinds of learning. It may be useful to slightly exaggerate, as well. If you want to carry your head further back, then go for a half-hour walk every day and practice keeping your head in the “right” place, or even further back than that. Don’t worry about practicing the rest of the time, any more than you would learn guitar by carrying it around with you at all times and strumming every time you can think of it. Just set up a conscious, well-defined practice time.

Physical assistance can sometimes force the issue effectively. For instance, I don’t think that I ever would have learned to sleep on my side without the help of a pillow. To this day, I still need a pillow in my way to prevent me from rolling onto my stomach. Obviously, there is almost no limit to the creative possibilities here.

If you have a specific postural challenge, such as a tendency to thrust your head forward at the computer, taping might offer you the best effort-to-reward ratio.
Taping can accomplish the same thing as discipline, but without the force of will. Simply apply medical tape — available in any drugstore — to the skin in such a way that it becomes impossible to position yourself incorrectly.
For instance, in a case of head protraction, pull your head backwards and apply a length of tape along your spine from your hairline to between your shoulder blades. The moment you try to move your head forward, you will get a nasty yank on your skin. No discipline required!
Taping is an irritating but highly effective method of forcing your postural reflexes to adapt. It is useless for more general or subtle postural degeneracy, however.

Many of the suggestions so far are just various ways of trying to “adjust your defaults” (Kabat-Zinn’s phrase) — to create a new normal state. Earlier I mentioned Oliver Burkeman’s experiment with a chair he “perched” on and how it was “extremely uncomfortable,” but he then describes an interesting change:
Now I don’t sit for too long, because it’s simply no fun to do so. After a few weeks, I realised that something intriguing had happened: I’d switched my default state. Standing or strolling was now my automatic, baseline behaviour; sitting was something I actively “did”.
Is being forced to avoid an uncomfortable chair a victory? A lasting one? Or will Mr. Burkeman revert sooner or later to comfier furniture? My money is on reversion; I’m doubtful that his “defaults” have truly been “adjusted” (which is just another way of talking about breaking old habits and forming new ones, no more or less profound or reliable than resolutions made around January 1).
Nevertheless, it is an interesting way of trying to change your posture, or any bad habit, and probably as good as any other.

It’s a popular notion that poor posture is caused by “tight” muscles pulling on our skeletons unevenly, like pathological ship’s rigging. I recall an elaborate demonstration of this principle in massage therapy college. An instructor tied several strings to me to simulate muscles and pulled on them in various patterns to show how tightness could warp my posture. The demonstration wasn’t memorable for the reason he would have liked.56
Undoubtedly the best known specific form of this idea is that tight hamstrings cause bad posture, and therefore that stretching them will improve posture. This was specifically tested in a 2012 experiment.57 I’m afraid it didn’t work. Although hamstring extensibility was indeed improved by a fairly ordinary stretching program, it had no effect on posture. The results are probably all the more believable because I strongly suspect the researchers were hoping to prove that stretching hamstrings is good for posture, and researchers are remarkably good at finding what they hope to find. But it seems the data were just not there to exaggerate or distort.
If stretching hamstrings has no effect on posture, I doubt any other kind of stretching does either. So this is a dead end, and yet another of many examples of how stretching “works” only in the sense that it will make you a little more flexible, temporarily, but the value of that flexibility is dubious indeed. For many other examples, see Quite a Stretch.

If force of will is the worst way to improve posture, being generally physically active in a variety of ways may be the best: not only somewhat effective, but a good idea for many other reasons too, of course.
A sedentary lifestyle contributes significantly to the degeneration of postural reflexes. NASA discovered this while studying the physiological effects of inactivity. “Use it or lose it” is the unsurprising biological lesson here: organisms adapt quickly to stimuli and stresses, and atrophy quickly without them. Therefore, probably the simplest cure for eroded postural reflexes is to simply do more with your body — but nothing in particular.
While it might make sense to choose activities that are specifically challenging to your posture — and you can certainly do that if you choose (see the next section) — the spirit of this suggestion is that you can probably get decent bang for buck without focusing on posture-challenging activities. Just by doing anything you like: salsa dancing, swimming, golf, whatever. A physical challenge like paddling (dragon boating), for instance, forces you to learn how to use your upper body (very) differently. The risk is that you will simply take postural dysfunction into the new activity, but the great potential benefit is that the enthusiasm you feel for the new activity will magically inspire new habits. Many people have permanently broken old habits by taking up an exciting new activity that required being different to enjoy or succeed at.
Inspiration — not discipline!

Add some instability — manageable postural challenges — to your activities, even otherwise sedentary ones. For instance, sit on an exercise ball or a wobble cushion (a funny little balloon pillow that creates an unstable surface) instead of a chair while working at the computer.
Buy a Wobble board and stand on it … while you watch television.
If you’re lucky enough to live near a beach, walk on the sand. Sand walking and running are particularly exhausting to the postural muscles.
Many exercise activities are more obviously challenging to posture than others. Where else but in a yoga class are you going to be asked to stand on one leg? Pilates, taijiquan, dance, martial arts, even a general fitness class — all can specifically demand coordination and stability not ordinarily present in your life.

Posture is the elephant in the corner of the ergonomics room. The biggest misconception about ergonomics is that it’s about facilitating good posture. It’s much more about eliminating sources of postural stress — or it should be, anyway.
In practice, ergonomics seems to mostly be “commercialized posturology” these days — that is, it’s the product and marketing division of the “science” of posture. And it’s all the more potent because it contains the legit seed-of-truth at the centre of all debate about posture. It’s even a pretty good-sized seed, like an avocado pit. But with sooo much bollocks around it.
It’s amazing what quacks can sell without a seed of truth, just an emotionally appealing idea (“one weird trick”), or something that sounds plausible to the ignorant (“quantum”!), or a fascinating sensation (spinal popping). But when you add an actual nugget of legitimacy? A real baby in the bathwater? An industry is born! An industry powered by claims that reach far beyond that legitimate premise. Despite the seed of truth, the marketing of ergonomics products is mostly powered by a never-ending supply of hyperbolic hype about the clinical importance of posture.
Let’s consider ergonomics more idealistically. What should it be? What is it when you strip away the absurdly excessive pursuit of alignment?
Ergonomics is the not-quite-a-science of arranging or designing things for efficient use. Poor ergonomics not only creates direct postural stress challenges — such as reaching too high for a computer mouse — but may also force people to learn bad new habits in order to cope. Computers have made slouchers out of a lot of people.
Extremely poor ergonomic design is usually obvious, but there are many more subtle cases as well. Improving the ergonomic design of your office or home could be simple, but not every solution may be practical or affordable. For example, I frequently recommend investing in a headset for your phone so that you don’t cradle it with a tilted neck. Headset technology has become both effective and affordable, yet many people haven’t considered this solution. When you’re upgrading your ergonomics, try to think outside the box, and don’t just pick the low-hanging fruit: the best changes may require some hassle and/or expense.
I have often seen patients complain bitterly about their office chair. Being prone to aches and pains, I can’t imagine why anyone would put up with a really bad chair for more than about three days. Either the boss agrees to get you a new chair, or you go buy your own. But people balk at asking and balk at the expense. Talk about penny wise and pound stupid! It’s your back — if it’s being relentlessly irritated by a chair at work, change the chair, period, whatever it takes.
The dirty little secret of ergonomics in the workplace is that it’s usually all about making the best of a bad situation. Discussions about ergonomics routinely overlook the fact that long work days in a chair are just a fundamentally bad idea — no matter how good your chair is. Ergonomics should not be focused on ways of making people more comfortable with a bad situation — almost a conspiracy against workers — but rather on improving the situation. Conventional ergonomics, when “arranging things for efficient use” — tends to exclude the most important thing in your workstation: you!
What a perfect comic strip I found! This exactly illustrates what I’m trying to say: that conventional ergonomics solutions may be missing the point & often get out of hand.
The consequences of ergonomics that ignore you range from the irritating to the traumatic. This fascinating collection of videos of ergonomic disasters has some examples.

This section used to be a critical analysis of a specific, trademarked method and the theories of its founder, which I bought into for a while early in my career. However, his method has not thrived, and I’m not sure he’s even in the guru business anymore, so I’ve stripped out the specifics and made this section into a more anonymous, generic example. Methods like this are a dime a dozen.
This Posture Modification System (PMS) makes claims that do not have a sound scientific basis and cannot be made with the confidence that this would-be guru makes them. For instance, the website advertises that PMS “expands the fundamental concepts of physics” — language that is irrelevant to therapy. Worse, it’s grandiose and melodramatically overconfident.
The big idea of PMS is that a deviation from an erect posture can be corrected by “exercising in the plane perpendicular to the deviation.” In theory, the body “knows” that a movement in one plane — say, flapping the arms up and down — can’t be performed efficiently if you are leaning forward or backward. Hence, every flap of the arms tends to stimulate the reflex that pulls you upright.
It’s a clever notion, but it is just a notion, completely devoid of evidence. And applying the principle is not straightforward: to use it, you would need the assistance of the founder himself, or a practitioner certified in his technique (and there are not many of them). You would have to invest considerable time, money, and energy … and all based on the self-serving say-so of an aspiring posture guru.
I’m embarrassed to admit that, for several years, I taught a simplified version of PMS to my own clients. I was not always a good critical thinker — it’s something I’ve learned over the years, in part from this experience. Eventually I abandoned PMS due to its fussiness and inconsistent results. Its failure to impress me was one of the major early causes of my disillusionment with both structuralism and Modality Empires. This combination of extreme scientific uncertainty and practical challenges is a really great example of why “systems” for postural correction are so dubious.

Posture is almost certainly associated with some pain problems, but much more weakly than most people believe. Postural habits with clear consequences and easy fixes are almost unheard of. Much of so-called “poor posture” is actually just postural stress and being stuck with bad ergonomics — not really a postural problem at all. Many people seem to be unusually vulnerable to poor postures and postural stress, but these people also may not have a posture problem, but a pain problem. And many more elements of poor posture are probably the result of long-term biological adaptation that is either extremely difficult or impossible to change. About the only clear benefit to tinkering with posture is that it can affect mood, emotion and probably pain sensitivity.
Trying to change posture is probably not worthwhile for most people, most of the time. However, if you want to try it and see, your best bet is probably increased activity, especially tasks that require coordination, and especially anything you enjoy — an activity that inspires, rather than one that requires discipline. Ergonomic tuning may also be particularly helpful, especially with specific challenges. “Technical” and “advanced” methods taught by posture gurus are generally more or less wildly speculative and completely untested scientifically.

How did I make a young massage therapist cry? I told her I didn’t want to spend $1/minute on a postural “assessment.”
I was polite and nice about it, but she was one of those deer-in-headlights youngsters who probably would have burst into tears at the slightest provocation. Sort of adorably, she tried to take a professional stand: “This is what I need to do in order to do my job properly!” Insert tremulous little foot stamp. But when I continued to politely insist on getting a massage instead of standing there in my shorts hemorrhaging cash, with no conceivable improvement to my experience, the lip started to quiver and then she pretty much lost all composure. Oh dear.
And why did I do that? Joe Brence, PT, explains it very nicely: Drop the plumb line … static posture assessments were so last decade.
At that point in my career, I’d already had about a bazillion postural assessments, with every imaginable rationale … and every possible result. Although there are certain themes (yes, lookit that, my right foot does turn out, by golly), by far the strongest theme of all is that the results of postural scans are extremely inconsistent. And the idea that such “assessments” can meaningfully inform one hour of treatment is really pretty hilarious.
Some excellent comments on this topic from Facebook discussion:
Moving assessments are way less boring for everyone, and convey much more information, and still allow time for the practitioner's brain to cook up a way to begin to implement a treatment strategy/path into and through the morass that lies ahead.

This article has a long, unrecorded history. It was one of the first long articles I ever wrote about health. The original version was sprawling and rambly and weird — too philosophical — but it had a lot of good ideas in it. In about 2005 or so, I decided I needed to offer my readers something more practical, and I wrote a new article focusing on reviewing exercise strategies for changing posture — but that was still an early effort, written when I was just getting started as a science writer, and it just wasn’t all that good. I updated both posture articles a few times over the years, and then finally in 2012 decided it was time for a complete rewrite. This is the result. There’s still a lot I’d like to do with it, though. Amazing how much there is to say about something that I think is “mostly much ado about nothing”!

Around the web:
- “Does Bad Posture Cause Back Pain?,” Todd Hargrove, BetterMovement.org. An articulate, thoughtful, and largely skeptical analysis of claims about the links between posture and pain, well supported by evidence. Hargrove wraps up with refreshingly positive recommendations about “what to do instead of worrying about posture.” His final advice: “don’t worry too much about trying to change your static posture to conform to some ideal. It is not a likely contributor to back pain.”
- “Dear Mike and Friends: Why Sitting Posture Is Mostly Irrelevant to Future Pain,” Greg Lehman, GregLehman.ca. This is a detailed debate-style exploration of the links between posture and pain, for a professional audience. It does a great job of respectfully contrasting expert opinions. As always, Greg Lehman models intellectual honesty and is scrupulous with his referencing. He concludes that “there is more concern about the things we aren’t doing when we sit rather than the actual posture associated with sitting.”
- “The fall of the postural–structural–biomechanical model in manual and physical therapies: Exemplified by lower back pain,” Eyal Lederman, Journal of Bodywork & Movement Therapies, 2011. This article is a bloody brilliant deconstruction of the underlying assumptions of the vast majority of pseudo-quackery in the manual therapies. It’s technical and academic, not for the lay reader, but absolutely required reading for professionals. Be sure to read his other excellent essay, “The Myth of Core Stability”.
- “Types of Posture: Overview of the Evidence About Pain,” Nick Ng, Massage & Fitness Magazine. One of the most detailed sources of good quality posture information on the web. This page is the hub of a substantial library of articles that all take a solid, science-based approach to different postural bogeyman, like “upper cross syndrome” or “cervical lordosis” or “anterior pelvic tilt.” Again and again, the conclusion is that posture is “usually not a strong influence on pain, as indicated in the current scientific evidence.” And that evidence is cited, cited, cited! Which is lovely to see.
- “The Corrective Exercise Trap,” Nick Tumminello, Jason Silvernail, and Ben Cormack, Personal Training Quarterly, 2017. The authors gently but decisively tip over the most sacred cow of personal training and therapy: corrective exercise, which is grounded in the assumption that there is something in-correct about patients — fragile, weak, or uneven — which must be fixed by sufficiently expert and precise exercise prescription.
- “Is the Pandemic Breaking Our Backs? Test-driving a batch of posture-enhancing devices that are supposed to make you stand tall,” Patricia Marx, The New Yorker. More of an interesting bad example than actually recommended reading. It’s a whimsical tour of many claims and beliefs about posture and its correction, without any substantive critical analysis of them. While the tone is slightly bemused, as if the author only knows how to write with one eyebrow raised, she also never gets around to being skeptical about anything (other than inserting a couple token contrarian expert opinions). As critical analysis, the article fails completely: no one is going to learn anything from it, except that posture is an evergreen-but-muddled topic. But you might be amazed by the sheer tonnage of nonsense on display.

- I was a Registered Massage Therapist with a busy practice in Vancouver, Canada, from 2000–2010, RIP. After that, science journalism and this website took over my career and they remain my sole focus today. See my bio.
- It may sound strange to many readers, but many experts don’t think the idea of “poor posture” has any validity or utility at all — that there is essentially no such thing. I tend to agree, insofar as everything that is “real” about “poor posture” can probably be described just as well without using the term posture at all and avoiding all its baggage. However, I still see some value in using the idea of posture.
- Belief in postural dysfunction can probably drive a nocebo — the opposite of a placebo: pain caused by the belief that something is wrong — plus even more harmful spinoff beliefs about general vulnerability and fragility, and often excessive zeal for postural “correction.” I have met people who were egregious posture hypochondriacs.

Posture, neck pain, and some other variables were assessed in several hundred 17-year-olds, and then again when they were 22. The risk of developing persistent neck pain was higher in those with a conventionally “good” posture, rather than the much-demonized “poor” posture of a slumped thorax and forward head posture.
What a delightfully counter-intuitive result!
“But they were young!” will be a common objection to this (and I have already seen it). But that hot take ignores half the data: the study did not just show that young woman with supposedly poor neck posture had minimal neck pain: it also showed that young women had more pain with allegedly “good,” erect posture. Despite their youth! Young people do get neck pain. And, in this study, the young ‘uns with “better” posture got more.
Importantly, it’s not like there was a huge difference here. The good-posture group wasn’t being destroyed by a plague of neck pain; their risk was only a little greater. If the numbers were flipped and showing a benefit to good posture, every posturologist in the land would be smugly touting it, but I would write it off as meaninglessly trivial.
There also wasn’t any difference in the young men studied.
So the only clinical implication is probably just that our traditional expectations of the importance of posture are just minor and doomed to be confounded by many other factors.
- Kneecaps evolved to jack up the leverage of the thigh muscles on the lower leg. The kneecaps push the quadriceps tendon forward, which gives the muscles a more favourable yanking angle. But there’s a price: the pressures under the kneecap reach truly astounding extremes. Even when the knee is just flexed, the pressure climbs quite high — enough to crush your finger like a walnut in a nutcracker, if you could get it in there. Sitting with your knees bent for long periods keeps the joint under that pressure. That’s a significant load on the joint tissue, which strongly correlates with the development of pain over time. It’s a perfect example of bad posture because it’s so avoidable, and because the danger isn’t obvious unless you understand knee joint mechanics and patellofemoral pain syndrome.

- Computer game companies are notorious for burning out young talent, eager new coders for whom the dangers of workaholism are still remote and abstract. They “sacrifice the body” for their work, spending long hours hunched over their keyboards in conspicuously awkward postures. Although ergonomics are a factor, mostly these are just obliviously awful postures, unforced postural errors. Most of them more or less get away with it, but some begin to suffer acutely. Having worked with and known many programmers, I know that a great many of them eventually become posture and ergonomics enthusiasts.
- Most people are at least dimly aware that sexual uptightness is a Puritan thing, that the Puritans bequeathed England and her colonies with the notion that pleasure is evil … and what’s more pleasurable than sex? (Possibly massage, and I doubt they liked that either.) Few people know that the Puritans also gave us the idea that rigid posture implies moral righteousness and strength of character. Postural laziness is a great moral failing in the Puritanical world view, which still pollutes the cultural DNA of modern civilization to a shocking degree. People still exaggerate the value of “good posture” for this reason, mostly unconsciously.

CONCLUSIONS: These results reinforce previous data suggesting that upright lordotic sitting postures are considered optimal, despite a lack of strong evidence that any specific posture is linked to better health outcomes. While postural re-education may play a role in the management of spinal pain for some patients, awareness of such widespread and stereotypical beliefs regarding optimal posture may be useful in clinical assessment and management.

Amazingly, he had actually managed to move it a few centimetres.

This classic, elegant experiment found no connection between leg length and back pain. Like most of the really good science experiments, it has that MythBusters attitude: “why don’t we just check that assumption?” Researchers measured leg lengths, looking for differences in “lower limb length and other disproportion at or around the sacroiliac joints” and found no association with low back pain. “Chronic back pain is thus unlikely to be part of the short-leg syndrome.” Other studies since have backed this up, but this simple old paper remains a favourite.

Assessments of leg length are common, both with the patient lying down or standing. Either could be reliable, but in this test they did not agree with each other. Two chiropractors with more than 30 years experience each assessed the same few dozen patients, and agreement between their results when they felt confident in them was “perfectly nil.“ Despite the widespread and confident use of each method, this test clearly suggests that at least one of them is unreliable, but it’s also entirely possible that both of them are.

Researchers used MRI to measure the size of kicking muscles in 54 Australian Football League players — very serious athletes, these guys, playing a very rough sport — and found that “asymmetry of the psoas and the quadratus lumborum muscles exists in elite AFL players.” Such asymmetries are widely believed by therapists to be clinically significant. Manual therapists, if they suspected such a distinct asymmetry in muscle mass, would enthusiastically and almost unanimously embrace this significant lack of “balance” as a major risk factor for injury, and a likely suspect in whatever injury or pain problem a person might happen to be experiencing.
However, the researchers also found that “asymmetry in muscle size was not related to number of injuries.”

This is a quirky but dubious little study that conveniently omits a critical result from the abstract. The researchers strapped a rimmed platform to people’s heads and got them to practice controlling the movement of a ball rolling on the platform — so, basically a circus trick. The subjects (only 14 of them) ended up with less postural sway, less jerkiness in neck rotation, less fear of moving, less “disability,” and “increased general health” by various measures, all of which is mentioned in the abstract with the promising and confident-sounding conclusion that the results “support the clinical applicability of the method.” Sounds fairly good, doesn’t it? But there’s a huge gotcha: if you read the actual article, it turns out that the results involved no positive effect on pain levels whatsoever. “There was no significant decrease in VAS [pain scale] scores after the four-week training period, or at six-months follow up.” The disconnect between the results and the abstract indicate that the authors probably have a strong bias in favour of structuralism.

The researchers looked for correlations between personality traits, postures and pain.

This is a review of ten scientific studies of the relationship between shoulder pain and thoracic spine posture, specifically kyphosis, the slouched or “hunchback” upper back curvature widely assumed to be a cause of pain. Six of the studies were judged to have a moderate to high risk of bias. Collectively these studies produced “moderate” evidence of no relationship: that is, there’s “no significant difference in thoracic kyphosis between groups with and without shoulder pain.” One study (with a high risk of bias) contradicted the others, identifying more kyphosis in people with shoulder pain. There is strong evidence that shoulder movement is greater if you’re straighter.

Posture is widely assumed to be a cause of pain, especially back pain, but even one of the most classic poor postures — kyphosis, excessive upper back curvature, “hunching over” — doesn’t seem to cause any trouble.

Perhaps this paper should be titled: “The lack of association between cervical spine curvature and neck pain.” In 2007, Swiss researchers examined “the correlation between the presence of neck pain and alterations of the normal cervical lordosis,” and this was probably “the first study to explicitly examine these relationships in detail.”
Many therapists assume that there is not only a correlation but a causal relationship, a classic example of structuralism. However, looking at more than 50 patients with and 50 without neck pain — a large enough study to be meaningful — the researchers found “no significant difference between the two groups could be found in relation to the global curvature, the segmental angles, or the incidence of straight-spine or kyphotic deformity.” Thus they concluded that “the presence of such structural abnormalities in the patient with neck pain must be considered coincidental, i.e. not necessarily indicative of the cause of pain.”

This study of 150 young adults in Brazil found no link between neck pain and poor posture while texting, so-called “text neck.” They were surveyed on a number of factors, including potential curve balls like visual impairments, and observed by physical therapists. Regardless of their posture — whether they had any concern about it themselves, or based on the more objective assessment — there simply was no observable connection between neck pain and the way they were looking at their phones. If there’s any link, it’s subtle and probably only emerges in the long-term.
The possibility of a link emerging over many years of text-neck posture has yet to be investigated — handheld computers haven’t been around long enough for that — but these results do suggest that any long term link is probably minor, or there would be at least some detectable short-term warning signs.

Researchers examined 277 neck x-rays and reported a “statistically significant association between cervical pain and lordosis < 20 degrees” — in other words, painful necks tended to be flattened necks (about 10 degrees flatter than the lower end of what they defined as normal). They concluded that “maintenance of a lordosis … could be a clinical goal for chiropractic treatment.” A cynic might point out that the authors were chiropractors, and the odds that they would identify a justification for chiropractic therapy in the data were approximately “very high.” (It is also unclear and implausible that chiropractic treatment is capable of achieving the clinical goal of “maintenance of lordosis.”)
- Studies like McAviney et al are a dime a dozen. You can easily find more like it. Their shoddiness only reinforces the point — the only studies that are “finding” a clear, important connection between posture and pain problems are the sloppy, self-serving ones. Ergo, there probably is no clear, important connection.
- It is entirely possible that pain alters posture — indeed it’s rather likely (see Hirata et al). Simply showing a correlation between a postural pattern and pain does not really tell us anything except that they have “something” to do with each other.

This fascinating experiment produced valuable data on potential triggers for episodes of acute low back pain. Basically the researchers just a did a thorough and formal version of asking a lot of people — a thousand of them — what they were doing before their back pain started (as compared to other recent periods). They made an admirable effort to do this in a way that eliminated “recall bias,” but I am not completely confident they succeeded: people have strong ideas about what constitutes a risk factor for back pain, and people tend to perceive and remember what they want or expect to be true. Participants were asked to:
report exposure, including its time and duration, to each of the 12 putative triggers in the 96 hours preceding the onset of back pain. For example, for questions about manual tasks involving a heavy load would be as follows: so on the day of your back pain did you engage in any manual tasks involving a heavy load?
A lot of people are likely to remember it that way, because that’s what they already think causes back pain. The list of possibilities was also limited to classic putative risk factors, which means that if a risk factor isn’t a bit of a cliché, this study simply ignored it. I think that has real potential to confound the results here. Nevertheless, there were strong signals and fascinating patterns here, and “the results of this study demonstrate for the first time that brief exposure to a range of physical and psychosocial factors can considerably increase the risk of an episode of acute back pain.”

This famous paper presents the original evidence that “power posing” will not only make people feel more powerful but also cause some hormonal changes: more testosterone, less cortistol (stress hormone).

There probably is a power-pose effect, just not a dramatic one (see Gronau 2017).

Carney et al infamously reported that “power poses” not only made people feel more powerful and daring, but that they had a biological fingerprint: more testosterone and less cortisol (stress hormone). And then the trouble started: “these power pose effects have recently come under considerable scrutiny,” which is a bit of an understatement: there have always been strong concerns about both the science itself and the way it was presented (premature hype).
This meta-analysis took a crack at producing the “last word” on this topic. It was part of a special edition of Comprehensive Results in Social Psychology, in which Carney herself was deeply involved (see CRSP special issue on power poses: what was the point and what did we learn?). It concluded that follow-up evidence for the original finding was “very strong,” and yet with a spectacular hold-your-horses caveat: “when the analysis is restricted to participants unfamiliar with the effect, the meta-analysis yields evidence that is only moderate.”
Translation: belief in the power of power posing will make you feel more powerful than power posing itself! Expectations seem to be the more potent active ingredient.
“Expansive postures” probably do make people feel more powerful … but only a little. Unless you believe in them, in which case you’re really off to the races. Which is fine. (“Why not both?”)

- “God of the gaps” is an expression from atheism and skepticism. It refers to the way the idea of gods has always been used to fill in gaps in human knowledge: whatever we can’t explain in the universe is attributed to one god or another. Quackery proliferates in medical knowledge gaps like weeds between paving stones. “Gurus” set themselves up like little gods of those gaps: they exploit areas of mystery in life (and medicine), selling the appearance of answers in an area where there really aren’t many answers, if any. Posture is clearly a murky subject. Therefore there are gurus for it. This isn’t always a bad thing — it can be nice to have a thoughtful guide in the wilderness of knowledge — but usually it is.

High heels are often vilified, but this carefully done 2010 study showed that the body adapts effectively and minimally, producing quite similar functional results. The most interesting implication of their results is simply that “muscle structure may adapt to a chronic change in functional demand” — which might seem obvious, but that little bit of science has been hard to nail down over the years, and this is a good piece of the puzzle.
Chronic high-heel wearers do have shortened calf muscles, stiffer Achilles tendons, and a smaller ankle range of motion, but these changes “seem to counteract each other since no significant differences in static or dynamic torques were observed.” In other words, high heel wearers are not progressively disabled: their ankles work fine, just differently. This doesn’t mean there’s no conceivable harm (for instance, Kerrigan found evidence of harm to the knees), but it does tend to downgrade concern on the topic.
