A searchable, sortable list of hundreds of articles and blog posts
Type topics like “back pain” or “stretching” into the search box. Keywords are suggested as you type — choose one, or ignore them and type anything.EXAMPLEExample: To find featured and controversial articles about back pain, you want to enter “featured, back, controversial” — but you don't have to type it all. First type “feat” and then press enter to autocomplete the “featured” keyword. The list now only contains featured articles. Now type “bac” and press enter to completed the “back” tag. Finally type “contr” and choose the “controversial” keyword. The list now contains more than 200 articles that each have at least one of these tags, but the ones with two or three sort to the top. The list always sorts to show the best matches for your search at the top, but you can re-sort the list. There are many tags, like “fun” and “research.” MORE TAGSTag (keyword) suggestions popup as you type. Start typing knee pain and you’ll see that there are many items about knee pain! There are many other subject matter tags for all kinds of painful problems, like back pain, more for treatments like massage or chiropractic, plus dozens of other kinds of tags. Try typing size to pick a size tag. Searching for featured articles is a good way of finding the best. Some other useful tags are tags for specific areas: leg, head, knee, etc. Or tags for the tone of a post: fun, debunkery, deep for mind blowing items, or pro for more advanced content. And tags for different types or sizes of items are handy: search for little blog posts, or large tutorials, or excerpts from my books.

PFPS is a common kneecap pain problem — and yet almost universally misunderstood. Patients are often given exactly the wrong advice. There is no miracle cure for patellar pain, but this tutorial is much more detailed than anything else you can find, weighing in at 40,000 words. Both patients and pros can greatly improve their understanding of the options — and maybe that is a kind of miracle.

|Does Platelet-Rich Plasma Injection Work?+
Platelet-rich plasma (PRP) injections bathe troubled cells in a concentrated mixture of platelets from your own blood. Platelets are involved in clotting and wound healing, and so the more-is-better hope is that they’ll stimulate healing “naturally” — regenerative medicine, supposedly. Unfortunately, the hype and costs are high, there could be risks above and beyond the basic risks of any injection, and the science so far is completely discouraging — three major evidence reviews have ruled it “ineffective.” Although it’s plausible and interesting in theory, this stuff just can’t beat placebos in fair tests.An interesting treatment idea for arthritis, tendinopathy, muscle strain and more

However, it probably doesn’t do what you hope it’s doing. Although Epsom salt probably does have some physiological effects, it is unknown if there is a therapeutic effect on aches and pains … and somewhat unlikely. Most of the theories you hear are oversimplified and meaningless — for instance, nearly everyone says it is absorbed by osmosis, but that is false and impossible — and the known effects of Epsom salt don’t have much to do with common causes of pain. The heat of a nice bath is probably more therapeutic. The case for the healing powers of Epsom salt is mostly made by people selling the stuff, or recommending it as casually and imprecisely as an old wives’ tale.

EBM-First.com is a nicely done directory of reading recommendations and references for a couple dozen topics in alternative medicine. It’s surprisingly hard to find good reading lists…but not on EBM-First. The most relevant topics for pain and manual therapy are craniosacral therapy, energy therapies and reiki, homeopathy, magnetic therapy, reflexology, therapeutic “touch.”
As you can see, there’s a strong focus on alternative medicine’s goofier side: several topics I’ve barely touched on myself, because they’re just too remote from science and reason.

Many alternative health care practitioners, especially chiropractors, claim that they are as well trained as physicians. This is false. Doctor’s academic training is routinely longer, and — more importantly — most of their serious learning occurs during extensive on-the-job training, where they are thrust into demanding clinical environments and supervised for years as they deal with a great variety of clinical situations and many extremely sick and hurt patients. That hands-on phase of their training is where all doctors will tell you that they became professionals — and there is nothing like it in any non-medical health care training.Medical training is much longer and better than anything naturopaths or chiropractors normally get

|This is why I work hard+ |
So there’s this article I wrote for PainScience.com in 2007. It’s going to remain anonymous for the purposes of this post. Because it’s embarrassing.
The article has been bringing in a lot of readers per month for ages now, years, about 3000 of ‘em, with an average reading time of several minutes (which is very good; it means that people are actually reading it). So it’s a busy article for PainScience.com…but not so busy that it was really on my radar as a top article. Not a high priority. I have a few dozen in this league, and dozens more that get much more traffic.
So I basically haven’t thought about this particular article since I wrote it.

I found at least three cringe-inducingly obsolete key ideas in it. Nothing too horrible, but … just shabby old stuff I abandoned about five years ago, closer to when I wrote the damn thing than to the present. Words I’m really not proud to have my name on today.

Oh, my. It’s not a bad article. But it does contain multiple strong statements that I think are misleading to readers and embarrassing to me, statements so cocky that obviously it hadn’t yet occurred to me that there was any possibility of doubt. In 2007, I just knew!
It will probably take me a few hours to fix, which I just can’t do on the spot. It’s going to have to go in the to-do list, where it will rub shoulders with dozens of other similar chores, competing for my attention for weeks or months before I finally get to it.

“Modality empire” is my own term for an ego-driven proprietary method or mode of manual therapy — a sub-discipline — championed and promoted by a single charismatic entrepreneur. Most of the “emperors” have healer syndrome, lack humility, make big promises, and make their money from unusually expensive therapy, workshops and books. Professionals are sold on the opportunity to purchase credibility in the form of increasing “levels” of certification, but the quality of these certifications is completely unregulated and often dubious. A modality empire is as much a business model as a method of helping people. There is a lot of overlap between modality empires and quackery. Classic examples of modality empires include Ida Rolf’s ROLFING®, John Barne’s myofascial release, and John Upledger’s craniosacral therapy. Sometimes a modality empire is particularly unoriginal, re-packaging old ideas for a new generation of workshop consumers.A tradition of ego-driven treatment methods in manual therapy

|Does Arnica Cream Work for Pain?+
Homeopathic (diluted) herbal ointments for inflammatory pain, like muscle pain, joint pain, sports injuries and bruising, are quite popular, but their effectiveness is fairly questioned by many. Known to most customers as “herbal” arnica cream, most contain less than 10 micrograms of arnica per dose — dramatically less that what is needed of most substances to be considered a chemically active ingredient. Homeopathy is based on an exotic interpretation of physics that involves diluting ingredients to the point of completely removing them. Some of the herbal ingredients are less diluted and may be chemically active and more useful.
A few tests of homeopathic pain creams have been mildly encouraging, but mostly old and poor quality ones. In all good quality, modern scientific trials so far, they seem to do no better than placebo. It is possible that a benefit can still be proven, but it is not likely.A detailed review of popular homeopathic (diluted) herbal creams like Traumeel, used for muscle pain, joint pain, sports injuries, bruising, and post-surgical inflammation

|Applied Kinesiology is Bunk+
Applied kinesiology (AK) muscle testing is a pseudoscientific method of diagnosis used by many chiropractors and naturopaths, and denounced as an absurd parlour trick by everyone else. (AK has no relationship to kinesiology, the legitimate study of human movement.) Practitioners believe that changes in muscle strength, reacting to substances placed in the aura and probing questions, reveal the sensitivities and needs of the patient. This is about as scientific as a ouija board. There is almost no real AK research, of course: no real scientist would bother.
Patients are often impressed by AK, because it exploits potent illusions based on the ideomotor and observer-expectancy or subject-expectancy (power of suggestion) effects. It fools practitioners just as readily as it fools patients: most are deluded true believers, not scam artists.The skeptical position on applied kinesiology, a bizarre alternative medicine method of diagnosis

|Your Back Is Not Out of Alignment+
“Structuralism” is the excessive focus in the physical therapies on crookedness or “mechanical” problems in the body — what I call the biomechanical bogeymen. It is the source of much bogus diagnosis — things like tilted pelvises, short legs, abnormal spinal curvatures, or “misaligned” anything — and the cause of much therapeutic barking up the wrong tree. Such factors are much less important than many people still believe.
Structuralism has been challenged by many medical researchers and experts like Dr. Lorimer Moseley Moseley, Dr. Scott Dye (knee surgeon); or back experts Drs. Richard Deyo, John Sarno, and Nickolai Bogduk; soft tissue pain experts like the late Dr. Janet Travell, Drs. David Simons and Seigfried Mense (see Muscle Pain), or Dr. Chann Gunn, and on and on.
Many key scientific studies over the years have undermined major structuralist assumptions, like Finan’s finding that knee pain correlates more with pain sensitivity than arthritis; Grundy’s conclusion in Lancet that short leg length differences don’t correlate with back pain; or Grob’s findings that abnormal neck curvatures do not predict neck pain; or Moseley’s finding that a placebo for knee osteoarthritis is just as good as real surgery; or numerous MRI studies showing terrible correlation between structural problems and back pain (see Boden, Jensen, Weishaupt, Stadnik, Borenstein); or the astonishing finding by Haig that even narrowing of the spinal canal does not necessarily cause stenotic back pain; or the clear evidence that even dislocation of the upper cervical spine is often asymptomatic (Swinkels); and so on (and on and on).Debunking the obsession with alignment, posture, and other biomechanical bogeymen as major causes of pain

Regardless of efficacy, stretching is inefficient, “proper” technique is controversial at best, and many key muscles are actually biomechanically impossible to stretch — like most of the quadriceps group (which runners never believe without diagrams). If there’s any hope for stretching, it might be a therapeutic effect on muscle “knots” (myofascial trigger points), but even that theory is full of problems.

|The Medical Blind Spot for Aches, Pains, and Injuries+
Doctors lack the skills and knowledge to treat most common aches, pains and injury problem, especially stubborn cases, and even the best are poor substitutes for physical therapists. Many doctors are well aware of this, but some are alarmingly oblivious. Dr. Jonathon Tomlinson, an instructor at St. Leonards Hospital in Hoxton, explains that “undergraduate training is focused on hospital orthopedics (broken bones and anything else that’s amenable to surgery) or rheumatology (nasty inflammatory diseases) which comprise a minority of the aches/pains/strains and injuries that people actually suffer from.”
Medical researchers have done many studies showing that most doctors do not understand aches and pains or heed expert recommendations. A good example is a paper in the Archives of Internal Medicine showing that family doctors frequently ignore guidelines for the care of low back pain — see Williams et al. In 2002, Freedman et al wrote: “It is ... reasonable to conclude that medical school preparation in musculoskeletal medicine is inadequate.” In 2005 in Journal of Bone and Joint Surgery, Matzkin et al concluded that “training in musculoskeletal medicine is inadequate in both medical school and non-orthopaedic residency training programs.” In 2006, Stockard et al found that 82% of medical graduates “failed to demonstrate basic competency in musculoskeletal medicine.”Most doctors are unqualified to care for many common pain and injury problems. Especially the stubborn ones

Healing speed is of great interest, and people often believe that treatment X helped them to heal faster. It’s also a common marketing claim. Unfortunately, most patients aren’t the least bit knowledgeable about what constitutes a normal healing time, and should probably defer to clinicians who have seen hundreds or even thousands of examples — except that they don’t really know either, because they do know that healing time varies wildly depending on countless variables. People often recover faster or slower than expected for reasons no one can ever know. We also seem to recover faster or slower depending on which psychological “goggles” we have on (optimistic, pessimistic, etc).
The bottom line is that the natural variation in healing times tends to obscure the effects of treatments, and simply isn’t actually possible to know if any treatment helped us heal “faster,” because we can never know how long it would have taken without it. You also don’t know what will happen the next time. The only possible way to settle such questions and confirm a faster average recovery time — especially if it’s only a little bit faster — is with carefully designed scientific testing, and quite a bit of it.Can healing be hurried? Would we even notice if it was?

|Does Fascia Matter?+
Fascia is widely regarded as an exciting scientific frontier, with well-attended fascia conferences featuring “rock star” gurus in the world of massage and manual therapy. The main idea is that fascia — tough connective tissue wrapping around all muscles and organs — can get tight and restrictive, and needs to be “released” by pulling on it artfully. Unfortunately, although fascia science may be inherently interesting as biology, and fascial compartment syndrome is certainly a real and scary medical problem, no subtle property of fascia has yet been shown to be clinically relevant. No fascial pathology seems to be a factor in any common painful problem, and no method of fascial manipulation is known to “fix” fascia or even change it.
I have challenged fascia fans to cite clinically relevant fascia science, with no result years now. This article reviews three key candidates: well-known studies about fascia’s toughness, its contractility, and its fibroblasts. None confirm any clinical relevance of fascia, and one actually undermines it, showing that fascia is too tough to “release.” I also discuss the irrelevance of piezoelectricity, thixotropic effect, and contradict Gil Hedley’s popular fascial “fuzz” theory of stiffness. The article criticizes fascia excitement from a scientific perspective.A detailed critical analysis of the clinical relevance of fascia science and fascia properties

|Therapeutic Touch is Silly+
Therapeutic touch (TT) is hands-off aura massage, actual touch not included, and it is the most common form of energy or vitalistic medicine in North America. Most practitioners are massage therapists and, oddly, nurses. Many years ago I believed in it, but eventually I decided it was based only on wishful thinking, laughably naive references to quantum physics, and wide-eyed exaggeration of ordinary social interaction effects. Auras do not exist and cannot be felt, let alone manipulated therapeutically. Just as dousers and psychics have never passed a controlled test, TT practitioners cannot not detect a person by feeling their aura, which makes them look ridiculous.
It is peculiar and pleasant to have someone wave their hands all around you with friendly intentions, but those effects are minor and fleeting and it doesn’t matter what specifically the therapist does, because it’s the interaction that is the active ingredient — a placebo, in short. And placebo is nowhere near as “powerful” as people believe, and there are all kinds of ethical and practical problems with cluttering up the interaction with magical interpretations of what’s going on.No touch included! Auras don’t exist and can’t be felt, let alone massaged for medical benefit

|Fatigue-induced muscle rippling and quivering+
Muscle fibres do not normally contract all at once, as most people imagine. Instead they are organized into groups called “motor units,” one per motor nerve. Rather than firing all at once, the groups alternate their contractions, like pistons. At any given time, countless motor units are in different phases of contraction and relaxation. The units are so small and the switching system is so fast that their coordinated action seems to be completely smooth to us.
There is an interesting exception, though: if you get tired enough that a lot of motor units start failing to contract, the switching system fails because there aren’t enough motor units available for smooth contraction. This is why muscles start to ripple and quiver with very intense exertions.
This phenomenon has no official name that I know of. It is sometimes called “fasciculation,” and I used to do that myself, but it’s an error: that’s just the smartypants word for an involuntary contraction, a twitch or spasm. This rippling business happens in a resting muscle as well a contracting one.A short explanation of myokymia a fascinating muscle phenomenon

|Are experimental injection treatments “worth a try”?+ |
Rarely. The bar for “worth a try” is fairly high for invasive treatments. Even “minimally” invasive ones like injections should only be considered when at least their safety is established (and it rarely is). What you really need is clear, consistent evidence of non-trivial benefit across several good trials before anything injected is “worth a try.” Before that it’s more like “hey, it’s your knee, don’t stab it”!
Of course, what’s worth trying is always a very personal decision, because it’s as much about risk tolerance and desperation levels as it is about the treatment. But my point is that almost everyone should be wary of needles filled with mysterious meds. For an example, see Does Platelet-Rich Plasma Injection Work?

|Health Care Claims Are Special+
A claim is any unverified assertion. But not all claims are created equal. In health care and health science, “claim” implies a more self-serving assertion. If a claim could be used as a bullet-point in a sales pitch, it’s more claim-y. If it makes you (or your profession) look better, it’s more claim-y. And the more claim-y it is, the more it needs to be backed up.
This special case of the word claim comes from the thorny ethical challenges with selling care to sick, hurt people. All claims need critical appraisal and verification, but it’s just not as ethically critical if it has no claim-stink. Sagan’s idea that “extraordinary claims require extraordinary evidence” is not just about alien abductions and lake monsters. It’s also, in spirit, about more mundane but self-serving and profitable claims — a more common ethical hazard than truly extraordinary claims.In health care, claims often involve a more self-serving assertion

There are a lot of ideological factions in health care. Even my relatively small area of interest — musculoskeletal medicine and pain science — is amazingly factionalized. Sometimes it’s really hammered home when I get email from friends trash talking each other, both trying to recruit me, even while they are being very polite to each other publicly.
The longer I do this job, and the more incidents like that I observe, the more I believe that there are no guiltless factions — everyone is getting some stuff right, and some stuff wrong, and treating some ideas fairly and giving others short shrift. It just seems to be how human minds work. Confirmation bias everywhere!
Don’t get me wrong, though: some people are still a lot more wrong than others.

Complete hamstring avulsions — that is, complete ruptures of muscles where they attach to bones — are not necessarily obvious. According to O'Laughlin et al, they “can be difficult to diagnose acutely due to swelling and patient guarding, which may mask a visibly palpable defect and lead to delays in diagnosis.” Yikes!
In this case study, the only diagnosis was “hamstring pain” for several days, before the avulsion was finally confirmed by MRI, and surgically repaired on day 13. It’s not hard to imagine cases where the diagnosis would have taken much longer — too long.

|Does Therapeutic Ultrasound Work?+
Ultrasound therapy is the use of sound waves to treat musculoskeletal problems, especially inflammation (tendinitis, bursitis). It has been a popular therapy for decades, its use so widespread that it almost defines physical therapy. Unfortunately, although mainstream, it is not as scientific a treatment as most people assume. It has been generally undermined or damned with faint praise by one scientific review after another for more than a decade now. Between 1995 and 2008, what little science has been done on the subject was reviewed in ten papers I considered to be worthwhile (see Gam, Windt, Brosseau, Robertson, Welch, Baker, Buchbinder, Ho, Ho, Jamtvedt). Eight of those were unambiguously negative, some of them strongly so. Authors had almost nothing good to say about ultrasound. Conclusions like this one (from Windt et al) are the rule: “As yet, there seems to be little evidence to support the use of ultrasound therapy in the treatment of musculoskeletal disorders.” Some modern variants of ultrasound are expensive, hyped, and totally unproven for any or many conditions.Many concerns about the widespread usage of therapeutic ultrasound, especially extracorporeal shockwave therapy (ESWT)

|Pressure vs shock waves: is there an (important) difference?+ |
Maybe. Probably not. Neither is revolutionizing pain treatment anyway.
There are several different types of extracorporeal shockwave therapy. One of them, radial shockwave therapy, is often called “shockwave” therapy, but probably shouldn’t be, because it uses much lower velocity waves. True shockwave therapies use waves travelling faster than the speed of sound (in flesh), about 1500 meters per second. Radial shockwave therapy is a couple orders of magnitude slower, and would be more properly described as a pressure wave therapy.
It’s probably not quite fair to lump them all in together when assessing shockwave therapy…but I’m going to do it anyway for now (in my ultrasound article). Until such time as there’s compelling evidence that one flavour has impressively different and better effects than another, it’s all just variations on a theme: stimulating tissues with different sorts of sound waves. Does that seem reasonable?

So this study showed that more massage therapy helped neck pain, suggesting that perhaps other studies showing lackluster effects on neck pain “may have not administered adequate doses.” Interesting. Pretty nice study, with good news.
But! (There’s always a but, eh?)
Among other limitations, there was this one (and kudos to them for acknowledging it, I was really hoping they would): “inability to control for nonspecific effects of attention with the use of a wait list control design.” Ayuh. In other words, it’s not exactly a shocker that just spending a lot of pleasant time with a therapist might produce better outcomes than waiting for treatment. I mean, duh. The massage itself may well not have been the mechanism. Or it may well have been. Can it tell us anything? Yes: if massage helps neck pain, more massage probably helps neck pain more.

Their awareness of the failings and limitations of medicine is clear, but balanced by a strong and admirable enthusiasm to improve. If medicine is the unmitigated disaster that Juahar seems to think it is, I would expect to see a lot more doctors declaring it.

“The smell could almost be heard.”
That image refers to a child’s rotting leg — rotting because of the incompetence of traditional Chinese medicine, as described in The Reality of Ancient Wisdom, by Dr. Harriet Hall.This article is essential, morbidly fascinating reading. I didn’t think I could get any more cynical about ancient folk medicine. I was wrong! Dr. Hall packages up a few excerpts from an old book by a physician working in China in the late 19th Century. His matter-of-fact reports of the actual medical habits of the Chinese at that time are chilling, and a harsh reminder that traditional Chinese medicine was not wise and profound, but rather cringe-inducingly horrible, just as brutal and bizarre as any pre-scientific European “medicine.” In particular, the stories concerning acupuncture expose a mess of superstitious and vicious excess. Bloodletting was the tip of the iceberg. Little wisdom is possible in a state of profound ignorance.

New article about platelet-rich plasma (PRP) injection! And the first completely new content in a while. PRP is my most requested topic of the last year, so I’ve finally written an article about it, which I hope is now your go-to link for some sassy, referenced PRP negativity. The conclusion was more or less inevitable, but I pried my mind open on the topic for a while before letting it snap shut again.
“Cynics can stop reading here. You know this doesn’t end well.”
“There’s lots of stuff inside of me that I do not want to be extracted, concentrated, and returned!”

|Missing Serious Symptoms+
One of the most common and serious basic problems with alternative medicine is that ominous signs and symptoms of serious disease are often overlooked, misinterpreted, and minimized by many overconfident and under-trained “professionals.” Naturopaths, chiropractors, acupuncturists and massage therapists often have a haughty disdain for “mainstream” medicine.
Of course doctors often also overlook problems — nobody’s perfect (see Medical Errors in Perspective). However, the chances of a doctor missing a scary diagnosis are generally much lower, because they have vastly more experience with much sicker people (see Chiropractor, Naturopath Training Way Less Than Doctors).Alternative medicine often diagnoses overconfidently, overlooking or underestimating serious symptoms
|Sep 11, 14Sep '14||475|
|Medical Errors in Perspective+
Alternative medicine practitioners often point accusingly to medical error rates with the implication that their services are much safer. That’s probably true … in the sense that walking is much safer than driving. But if your profession had to treat huge numbers of people with dire injuries and illnesses, it would also have scary error rates.
Bad things do happen in hospitals, and stats about iatrogenic (doctor-generated) medical errors can seem alarming. However, to simply state that medicine kills and hurts people is unethical fear-mongering. Cars kill and hurt people too, and for pretty much the same reason: sure it’s risky, but the benefits are worth the risk, and huge numbers of people are willing to take that chance.
Medical systems deal with vastly greater numbers of much more serious cases than any chiropractor or naturopath, and many of them are no-win, rarely-win, or sometimes-lose situations with the highest stakes, terrible suffering and death. We should be cautious about criticizing that from the outside. Try working in a hospital for a while, try to be perfect, try to never have anything go wrong that matters!Medical error rates should not be used to spread fear, uncertainty and doubt

The idea of “toxins” is usually used as a tactic to scare people into buying some kind of de-toxifying snake oil. Obviously there are dangerous substances; the problem is with the kind of people who toss the idea around, the reasons they do it (fear, profit, ignorance), and because toxin claims are usually so vague that they are literally meaningless, except as a marketing message. Indeed, “detoxification” may be the single most common marketing buzzword in alternative health care.
The body deals with undesirable molecules in many ways. It eliminates some and recycles others; some are trapped in a safe place; and quite a few can’t be safely handled at all (metals). Most alleged “detox” treatments are focussed on stimulating an excretion pathway, like sweating in a sauna. But it’s not like sweating is broken and the sauna is fixing it! The only truly “detoxifying” treatments help the body eliminate or disarm molecules the body cannot process on its own. A stomach pump for someone with alcohol poisoning is literally “detoxifying.” So are chelation for heavy metals, and antivenoms.
I cover the specific idea of “flushing” toxins in Should You Drink Water After Massage? (Massage is wonderful for all kinds of reasons — it doesn’t need the support of the idea that it detoxifies.) For more general consumer advocacy and education about toxins, see “Detoxification” Schemes and Scams (from QuackWatch.org).The idea of “toxins” is used to scare people into buying snake oil

“Science doesn’t know everything” is a classic, common non-sequitur from people defending quackery.

|Masking Symptoms Is Under-Rated+
“Masking symptoms,” especially with medications, is often maligned because it doesn’t “aid healing” or “treat the root cause.” But masking symptoms can be a perfectly good idea, and it should not be eschewed just because it doesn’t have a real healing effect … because there are very few real healing effects! Maybe none. There are few or no known ways to actually improve on the biological process of healing. We can’t tell the body, “Hey, heal better, will ya?”
“Healing” is mainly about removing impediments to natural recovery, such as continued overuse and excessive stress. It’s not dictated by some mythical power to speed healing, but by a strong understanding of the nature of the problem and what pisses it off and slows recovery. The most idiotically simple example is that bad sprains need to be immobilized for a while, just like a fracture — and maybe that seems “obvious,” but it was actually common practice for decades to recommend excessive early mobilization.
Here’s a classic, trickier example: patellofemoral pain is often misdiagnosed and “treated” with strength training that tends to stress the knee even more, and yet it often works to simply avoid sitting with bent knees, because that position is more biomechanically “intense” than most patients realize. Removing that sneaky knee stress isn’t “healing,” per se, but it’s sure important!
Focus on facilitating natural recovery, and don’t knock a little “symptom relief” along the way.Masking symptoms,” especially with medications, is often maligned. But sometimes symptoms need masking!

There can certainly be something wrong with your spinal joints — there are a few possibilities — but “subluxation” and spinal joints being “out” are not defined clearly enough to be useful, and are probably quite misleading.
“Subluxation” is mainly a chiropractic idea of some kind of spinal joint dysfunction, with many shades of meaning — too many — depending on who is talking about it. However, it is inextricably entangled with the idea of a spinal joint being “out” of place, and it is this sense of the word that needs some debunking. Some chiropractors attribute great importance to subluxation. Most believe that subluxations cause neck and back pain, and — significantly — many also believe that they cause a wide variety of other health problems and so they “use spinal manipulation to treat visceral disease” (Homola). Subluxation theory has been both popular and controversial for many decades now, and it has never achieved medical respectability. Many experts, including quite a few chiropractors, actually deny that spinal subluxations exist in any meaningful sense.
It’s problematic that spinal manipulative therapy — the umbrella term for all kinds of spinal joint “adjustment” — is so often based on such a confusing and controversial concept. Subluxation has too much baggage to be a useful term. Let’s use more modern and specific terminology, and get away from the idea of spinal joints being “out.”Is there any such thing?

|Simon Singh Story and British Libel Reform+
Simon Lehna Singh’s story is now the most famous example of legal bullying of a science writer for commenting on controversial health care, with important consequences for free speech, and great personal significance (I was being legally bullied for similar reasons at the same time).
Singh criticized the British Chiropractic Association for endorsing spinal adjustment for children, famously calling it “bogus.” The BCA sued, exploiting Britain’s nasty libel laws, and the case got off to a rough start for free speech. Singh persisted until the case became a public relations disaster for the BCA, and they withdrew.
A science writer should be able to comment on genuine concerns on an important public health issue (such as correct treatment for children) without the threat and expense of British High Court libel claims. The cost of an opinion about a controversial health care issue should not be ruinous.

|The fate of medicine without reductionism+ |
“Reducing” complex systems in nature to their components is just one of many thinking and reasoning tools, not an all-consuming obliviousness to “the whole” — as often insulting insinuated by alternative medicine practitioners.

|‘Reductionism’ Is Not an Insult+
Alternative medicine practitioners often derisively accuse their critics of being “reductionist.” This is intended to sound wise and knowing, but sneering at reductionism is a transparently convenient way to dismiss rational objections to crank theories and flaky bullshit. It insultingly insinuates a lack of vision and savvy about complex systems (like the body). It’s just an ideological gripe, not a meaningful thought, about people who allegedly can’t see the forest for the trees. (This is quite ironic, coming as it usually does from barely-trained dabblers and dilettantes, people who clearly have not exactly mastered either forest or trees.)
Certainly reductionism can go wrong, like nearly any mental mode, but it’s not an intellectual failing. It’s just one of many thinking and reasoning tools … not an all-consuming obliviousness to “the whole.”Reducing complex systems in nature to their components is not a bad thing

Confirmation bias explains a lot about human nature. Most people know it best as “selective hearing” or “selective memory” — hearing and remembering only what you want to hear (see also “pareidolia”). Confirmation bias is a whole lot more: a dazzling array of devious and largely unconscious mental tactics and thinking glitches that lead people to confirm their beliefs and pet theories. We not only tend to ignore, deny and overlook anything that contradicts our point of view, but we also invariably notice, inflate and or even fabricate anything that supports it.
Confirmation bias is one of the main reasons that The Truth is so slippery, and both amateurs and experts alike are prone to significant thinking errors. There are people who consider it part of their job description to eliminate confirmation bias from their thinking — the best scientists and journalists, for instance — but it’s really difficult. Everyone has confirmation bias: it’s just how minds (don’t) work!Confirmation bias is the human habit of twisting our perceptions and thoughts to confirm what we want to believe

|The chemistry of the burn+ |
I get a lot of my exercise science news via Alex Hutchinson of Sweat Science. For instance, this interesting item about “the burn” of intense effort — what exactly causes it? Which molecules? According to Pollak et al, it’s protons, lactate, and ATP — and only in concert. “There was essentially no response whatsoever to the individual metabolites,” explains Alex, “so the receptors apparently respond only to the synergistic combination of all three.”
Surprisingly, this fairly unsurprising result is brand new information: the paper’s authors call it “the first demonstration in humans that metabolites normally produced by exercise act in combination to activate sensory neurons that signal sensations of fatigue and muscle pain.”

Hi, I’m back. The last couple weeks were consumed by an anatomy exam (and then some “special projects” I will remain deliberately mysterious about).

|It doesn’t go to my head!+ |
I’ve always had trouble remembering the name of the “cephalic” vein, because the name seems wrong. What does it have to do with the head? It doesn’t go to my head! I finally went looking for an explanation and found one quickly on Wikipedia: “Ordinarily the term cephalic refers to anatomy of the head. When Persian physician Ibn Sīnā's Canon was translated into medieval Latin, cephalic was mistakenly chosen to render the Arabic term al-kífal, meaning ‘outer’.”
Phew, I feel much better knowing that! (It’s also probably to stick in my mind much more better now.) And now I wonder how many other anatomical terms are based on mistranslations…
|Aug 1, 14Aug '14||100|
|Is there hope?+ |
One of the top five questions I am asked by email, about any condition, is simply Is there hope? The answer is nearly always the same…
Yes, there is hope! There’s never a guarantee, but there’s always hope, and recovery from most kinds of severe chronic pain is not only possible but fairly common. Unless you have a known serious aggravating factor — a major trauma, for instance — there is almost never any reason to fear that recovery from any chronic pain problem is impossible. For the same reason that pain can be absurdly persistent and out of proportion to any clear cause — because it is so brain-tuned — it also never loses the potential to finally shift and evaporate.
This thought was added to my Pain is Weird article, and probably should be in several other articles as well.

|Poisoned by Massage+
Massage is not a detoxification treatment in any sense, contrary to a popular belief. Ironically, it’s the opposite: post-massage soreness and malaise (PMSM) is probably caused by mild rhabdomyolysis (“rhabdo”). True rhabdo is a medical emergency in which the kidneys are poisoned by myoglobin from muscle crush injuries. But many physical and metabolic stresses cause milder rhabdo-like states — even just intense exercise can do it, and probably massage as well. This is substantiated by a case study of acute rhabdomyolsis caused by intense massage (see Lai), by many well-documented cases of exertional or “white collar” rhabdo, and by the strong similarity between PMSM and ordinary exercise soreness. A rhabdo cocktail of waste metabolites and by-products of tissue damage is probably why we feel a bit cruddy after biological stresses and traumas — even massage, sometimes. And you can’t “flush” the rhabdo away with massage or by drinking a little extra water. PMSM is just an unavoidable mild side effect of strong massage.Rather than being “detoxifying,” massage may cause a modestly toxic situation in the body

Digital motion X-ray (DMX) is an X-ray video: many X-ray images strung together to make a movie. The output is impressive. In theory, it can reveal serious problems that somehow eluded diagnosis otherwise. In practice, this unregulated and banned-in-Canada technology is primarily sold to neck pain patients by chiropractors, often for evidence in personal injury lawsuits, and is completely eschewed in medicine because of concern about radiation exposure. DMX undoubtedly has some potential to show important things, but is it worth an increased risk of cancer to diagnose conditions that, mostly, can and should be diagnosed any other way? It’s not completely out of the question, but you should get multiple medical opinions and think hard before resorting to this exotic diagnostic method.What’s the risk from the radiation exposure?

|Why fascia matters medically (get ready to cringe)||Jul 1, 14Jul '14||425|
The idea of “adjusting” the spine refers to many different manual therapies that wiggle, pop and otherwise manipulate spinal joints. The correct umbrella term for these treatments is “spinal manipulative therapy” or SMT. Expert opinions on SMT range widely, with some prominent medical scientists expressing strong concern and skepticism. Its provenance in chiropractic subluxation theory is dubious, its benefits are minor at best, and yet there are serious risks, even including paralysis and death in the case of SMT for the joints of the neck.
Despite all the controversy, there has been little high quality scientific research to determine whether or not SMT is safe and really works. Major science reviews have either been thoroughly discouraging. Thus, SMT fails the “impress me” test — it can’t possibly be working any miracles.
And yet spinal joint popping in particular is something that people crave, and most clinicians believe that some forms of SMT can be helpful to some of their patients, some of the time. There seems to be almost no doubt that there is something of therapeutic interest going on in SMT, at least some of the time.Spinal manipulation, adjustment, and popping of the spinal joints and the subluxation theory of disease, back pain and neck pain

Surprisingly, Frobell et al found that it’s not clear if a torn anterior cruciate ligament should be surgically repaired. In a randomized, controlled study of 121 young adults with acute ACL injury, there was little difference between getting reconstructive surgery right away and just doing normal rehabilitation. Given the structural importance of the ACL ligament, it’s amazing that it can recover from major trauma without surgery approximately as well as it can without. This study did not show that ACL repair is never or rarely necessary, but it certainly strongly suggests that it’s less crucial than most people would expect.

|For whatever it’s worth+ |
For many people, a diligent effort over a period of weeks might well increase your range of motion. In 2011, a nicely done experiment by Marshall et al showed that regular hamstring stretching substantially increased range of motion in normal university kids. Specifically, after “a 4-week stretching program consisting of 4 hamstring and hip stretches performed 5 times per week,” their range increased about 16˚ or 20%. That’s a real result. For whatever it’s worth. Regardless of what it does for flexibility, stretching remains amazingly useless for nearly any other popular or clinical goal. See Quite a Stretch. And see the next post for more discussion about the implications of this study: Plasticity versus tolerance.

|The Better Movement Book+ |
Just published! When I’ve read it, I’ll review it, but I predict good news: this is likely to be a fine book, and a great reading recommendation in countless places around PainScience.com. Todd Hargrove is a clear thinker and terrific writer. For years now, I’ve been reading his blog — www.BetterMovement.org, similar to this one in so many ways — and routinely kicking myself for not writing about a topic as craftily as he did, or as diplomatically, or as insightfully. He’s one of those writers that keeps me striving to refine my own skills. Buy the book from Amazon (paperback for now, Kindle coming soon).

|Hyperaesthesia of the shins+ |
Bartonella quintana (or trench fever, or five-day fever), is a disease carried by body lice that causes, weirdly, hyperaesthesia of the shins — that is, generally heightened shin sensation, though mostly just heightened pain. However, this is unlikely to cause any diagnostic confusion with shin splints, since trench fever also causes a nasty fever and many other unpleasant symptoms, like fierce headaches and eyeball pain. Nevertheless, perfect sidebar fodder for my shin pain tutorial.

Interestingly, Vibram’s claims are still online for now — I wonder how much longer? — and they are just as bold and unsubstantiated as I remember.
It’s good news, but companies will keep making premature health claims as long as the potential profits trump the risk of getting spanked for it (so, forever). Lots of discussion of this item on Facebook, and I’ve updated my barefoot/minimalist article: Does barefoot running prevent injuries?

|The Cassidy paper+ |
Since its publication, “the Cassidy paper” has been the defensive citation used by chiropractors to respond to accusations that neck adjustments involve a risk of stroke, and therefore should not be conducted without proven benefit and informed consent. The abstract seems to strongly exonerate chiropractors: “We found no evidence of excess risk of VBA stroke associated chiropractic care compared to primary care.”
“But abstracts are like movie trailers,” as Dr. Mark Crislip wrote. “They give a flavor of the movie, but often leave out many important plot devices and characters. … If you were to read this article in its entirety, you would not be so sanguine about the safety of chiropractic.” He goes on to explain exactly why in one of the earliest popular posts on ScienceBasedMedicine.org, Chiropractic and Stroke: Evaluation of One Paper.

Fun fact: the spine is tough and strong and difficult to stabilize without surgically installing screws and rods, and even then it’s tricky: spinal fixations occasionally fall apart (my wife’s did). In fact, it’s so hard to control spinal movement that the value of external bracing in spinal fracture rehab remains controversial. Worse, one fascinating experiment (Rohlmann et al) showed that bracing may actually cause some some, dysfunctional spinal function — resulting in less support, rather than more!

I’m pleased to announce the first complete professional editing of two of my books — about plantar fasciitis and iliotibial band syndrome. Although the difference will not be obvious to most readers, several hundred improvements and corrections were made to each, and the reading is definitely smoother.
What took me so long? Logistics and cash. Like any truly professional writer, I always knew I needed good editorial help, but that can be hard to find and pay for. Editing a book is a Big Deal. But PainScience.com has grown to the point where it finally got important and affordable, and I was lucky enough to find a skilled, reliable editor: JoAnne Dyer of Seven Madronas Communications. After working with JoAnne on many smaller projects over the last couple years, I asked her to start working on my books. Two down, six to go!

|So…what does work, Mister Smartypants?+ |
I am often criticized for failing to suggest alternatives when criticizing bad ideas in therapy, especially in my article about “structuralism” (overemphasizing biomechanical factors in therapy). It’s a bogus gripe: failing to suggest a wardrobe for the emperor to wear tomorrow doesn’t make him any less naked today. Structuralism is a deeply flawed basis for therapy regardless of whether anything can readily replace it. But I’ve gone ahead and made some simple suggestions anyway, in a short new conclusion to the article (link takes you directly to the conclusion).
There will be much more on this so-what-does-work theme over the next couple years. I’m just getting started on it.

|Oh, stretching! Can you do anything right?+ |
My main stretching article now includes a section on the failure to treat contracture (a scar-like shortening of soft tissues). Stretching always gets the benefit of the doubt, whether it deserves it or not. Most people and most professionals probably assume that long, intense stretches are an effective prevention/treatment for contracture. It is not an assumption held with much conviction, I imagine — it’s just that stretching always gets the benefit of the doubt, whether it deserves it or not, and it seems to “make sense” that stretching would be a cure for contracture.
Common sense fails again, I’m afraid. Continue reading (link goes directly the new section).

When my customers request refunds, which is unusual, by far the most common reason given is that the book didn’t solve their problem. About half of them add some kind of complaint about my legendary negativity. Here is a typical recent example:
Not many self-help books go to great lengths to stifle false hope and unrealistic expectations…but mine do. My shin splints book is not intended to “decrease shin pain,” and I warn readers about that, in several ways, in both the free introduction and in the main text. In fact, I would say it’s impossible to actually read and understand my book and still think that it should have “fixed” anything. It’s an unreasonable expectation of any book… but particularly one that goes well out of its way to caution readers against that expectation!

|Trigger Point Doubts+
People routinely experience muscle pain and acutely sensitive spots in muscle tissue — “muscle knots.” They can be surprisingly severe, and massaging them often seems to help quite a bit. What’s going on? The dominant theory is that a trigger point is a patch of tightly contracted muscle, an isolated spasm affecting just a small patch of muscle tissue. Unfortunately, after a few decades it’s still just a theory, and trigger point science is a bit half-baked and somewhat controversial. It’s not even clear that there is really a problem in the meat at all; it could be a sensory “disturbance,” for instance. Meanwhile, people keep hurting, and there is little doubt that there is an important, almost epidemic phenomenon here in need of explaining and treating. Massage — especially self-massage — remains a safe, cheap way of trying to deal with it, and there is some evidence that it can provide some meaningful relief (e.g. Furlan 2008 is probably the best example). That’s why I have a large tutorial devoted to how to self-treat “trigger points” — whatever they really are. But it’s very important to keep in mind that they are not well understood.Is there really such a thing as a muscle “knot”?

|Tissue Provocation Therapies+
"There are two “laws” of tissue adaptation, one each for hard and soft tissue. Wolff’s law is that bone will change and strengthen in response to loading. This was first noticed by Julius Wolff in the 19th Century, who got the naming rights. It was greatly refined in the mid 20th century by Dr. Harold Frost, an American surgeon who studied bone biology, and published scientific papers more often than I change my socks. The full details of how bone responds to stress are described in his Mechanostat model. The corollary in soft tissue is the obscure and much less developed Davis’ law. (No one even seems to know who Davis was.)
Although there’s no question soft tissue does adapt to stress, the responses of muscles, tendons, and ligaments are much more complex and less well understood. Many treatments are based on the idea of forcing adaptation or “toughening up” tissues by stressing the tissues. It has always been a reasonable idea, but the devil is in the details: what constitutes the “right” amount and kind of stress is difficult to know, and the results of such therapies have generally been highly inconsistent.Can healing be forced?

|The View from Somewhere+
Readers often prevail upon me to be “objective,” but it’s an over-rated virtue. I am often criticized for a lack of it — always by somone who disagrees with me. And sometimes I am praised for my neutrality — always by someone who agrees with me. But I am not impartial on any of the controversial questions in my field, I’ve never met anyone who is, and I don’t aspire to it.
Objectivity and balance are highly over-rated as journalistic virtues. They are mostly a pretentious delusion, and you should actually beware of those who claim to have them. See Jay Rosen on “the view from nowhere.” And Dan Rather said it well: “I don’t like the word ‘balance’ as applied to journalistic work, because to me, that carries with it at least a connotation that, if you run 15 words about the Republican Party, then you’ve got to run 15 words about the Democratic Party. That’s balance. But I think “fairness” is the word I prefer” (interviewed by Hedrick Smith on PBS, 1996).
Instead of expecting balance, look for someone with a View from Somewhere — from someone who isn’t afraid to disclose and own a bias. That is my goal. Not only will I fail to achieve the ideal of “objectivity,” I assume that my biases are inevitable, constantly egregious, and utterly human. We are all bias machines. We can only keep a bemused eye on this frailty, do some damage control, and try to avoid being emphatic or overconfident about much of anything other than the rise of the sun, death, taxes, and the absurd fallibility of confidence itself. The ideal is not be unbiased, but to be biased with integrity.

|Kinesio Taping Review+
Most therapeutic taping is either practical (stabilizing a sprained ankle), or aims to tinker with more subtle biomechanics. Taping has gotten a lot hotter in the last few years with prominent new products and branding, and lots of hype and claims about therapeutic effects, prevention, and performance enhancement. New materials that may achieve different and possibly superior benefits, but probably not much. It doesn’t work biomechanically, as many professionals assume. It’s more likely that the odd sensations change function and reduce pain, but that kind of effect tends to be minimal, and hard to predict and control.A quick analysis of that colourful therapy tape that was so popular at the Olympics.

Mea culpa: that knee ligament “discovery” I linked to yesterday? Not so much discovered as “looked at more careful like.” Studied, classified. Perfectly worthwhile research, but over-hyped by the media reporting about it. It was definitely hyperbole to describe it as a discovery. It’s been known of for at least a century, and a paper last year reported finding it in every knee they looked at. I didn’t look more carefully at the story because it was just a minor interesting thing (and anatomy really is never done), but it’s amazing what even a tiny little bit of hype will do. Hat tip to Tony Ingram of BBoy Science for raising my awareness.

Extreme examples are educational. For instance, we know from the experience of ultra runners that it is possible to run in a way that is less hard on your body. Once again, consider the case of Philippe Fuchs, who ran from Paris to Beijing, covering ~5,100 miles in 161 days. His primary concern was his “ability to keep absorbing muscular and skeletal punishment day after week after month,” of course. By the time Fuchs finished, he had developed an endurance stride that was clearly shorter and lower: he padded along with about 6% more steps per mile, a whopping 30% less time in the air, and 11% less landing force. I’m betting he wouldn’t have made it without those adjustments. Fascinating!

“It’s all coming from the ____, I know it!” The temptation to boil the cause of chronic pain down to a single culprit can be almost overwhelming, but you must resist. Single causes of long term pain are almost unheard of. Nearly all chronic pain is a witch’s brew of different factors, complex by nature (not just coincidence or bad luck). This makes it harder to beat overall, but some factors are more treatable or manageable than others. Find and work with those.

|Touch-testing the world+ |
new article about Kinesio Tape® and similar products, which explains that therapeutic taping is mainly just a sensation tweaker, and that’s fine as far as it goes. We humans are neurological input-output machines. We constantly, systematically, creatively tinker with how we feel … touch-testing the world. This is why I have no strong objection to therapeutic taping, but also why I will probably never be impressed by it: it’s just another method of playing with how our bodies feel, one of many. But it will never trump functional challenges as the main drivers of recovery and performance. The bottom line is always going to be that we have to push ourselves a little to get better than we are — and being taped just isn’t much of a challenge.
|Sep 19, 13Sep '13||130|
|Performance enhancement+ |
“Performance enhancement” is usually a problematic claim, because it’s commonly based on sloppy extrapolation from recovery effects (which are themselves often a bit sketchy). Even what genuinely helps people who are sick or broke is not necessarily going to do anything for fit, healthy people. Or vice versa. (Simple example: compression bandaging for swelling. Unambiguously handy in recovery … but useless if you’re not swollen!) Rehabilitation and performance enhancement are just different things. On the one hand, they are the same process with different starting points. On the other hand, how much value the body can extract from an input is generally proportionate to need. A glass of water is more important to a man dying of thirst, and novel sensation is more neurologically useful to an injured person than a healthy Olympian.

It is a widely and passionately held belief that back and abdominal strengthening will help back pain, and Pilates is the branded exercise system dedicated to core strengthening, so Pilates must be good for back pain, right? But in a recent test by Miyamoto et al, patients who did Pilates had “small benefits” compared to those who did not. And the test had a serious flaw: it neglected to compare Pilates to other any other kind of activity (shamefully sloppy design, fairly junky science). These results only add to the pile of evidence that exercise and therapeutic attention of any kind are probably good for low back pain. It’s only worth reporting these results insofar as they damn Pilates with the faintest possible praise — evidence that Pilates has no special power over back pain. I am not even a tiny bit surprised by this.

|Educated guesses+ |
Ideas based only on educated guessing about biology, however reasonable and plausible they may sound, have a nasty habit of falling apart when more directly tested. This is one of the strongest patterns in the history of medicine.
A classic modern example is autologous blood injections for tendonitis: an idea that sounds promising if you just talk about the biology, but fails when tested on actual patients.

Because, of course, what we see in magazines and movies aren’t really people anymore, but skilfully lit and pixel-manipulated artwork — beautiful in their own way, of course, or why bother? But they are only distant, abstract cousins to homo sapiens. In all my years massaging, I never experienced a client as “ugly.” It just isn’t possible when you’re actually paying attention to the person.

|Weights as good as a run?+ |
What if it was just as good for your aerobic fitness to lift weights as to run? Here’s a paper that says it probably is. The authors have a bias favouring this theory, and there’s no real evidence about it yet, but it’s plausible and they make several perfectly reasonable points about the basic exercise biology. At the very least, it does firmly support the idea that building strength is better for general fitness than most people realize (which is all I’m really after). More detail in the bibliography:

Hint: no (certainly not when properly defined). Todd Hargrove has “noticed that some of my colleagues in the bodywork community are somewhat disapproving of using a scientific approach to understanding how the body responds to manual therapy.” Indeed! But he’s also noticed a positive trend, and I agree: it is getting better, and it has a lot to do with blogging and social media. Nice post, with a nice mention for yours truly and several more I know well. Thanks, Todd.

|Should I run recklessly?+ |
Real question from a runner:
Um, no … in (at least) 2 important ways:
First, of course, there’s just a real risk of making any injury much worse that way. Duh! There are exceptions, but you need to know what those are — you need a clear and specific rationale for breaking a generally excellent rule.
And second, “stuffing” with pain-killers is seriously risky and useless to boot. Pain-killers are bandaids at best, possibly not even that, and definitely not a good long term solution, because there isn't a single one that doesn't have truly serious hazards with chronic use (not the least of which is their effectiveness wanes).
|Jul 30, 13Jul '13||120|
|Critical what?+ |
Critical what? Hardly a day goes by I don’t read something smart online about critical thinking: how important it is, how to do it, why to bother. It’s everywhere. So … why is so much not-so-critical thinking still floating around out there?! It seems odd.
The answers are obvious of course: above all, good quality thinking is a skill, because it requires working around obstacles that are truly unknown to us without training (obscure logical fallacies and sneaky cognitive distortions). It’s a hard skill to learn even for people who are super motivated. There’s almost no chance if it threatens comforting beliefs… or, worse, the basis for making a living!
But it still seems mighty peculiar and ironic that there’s so much good information available about critical thinking that isn’t being used.
|Jul 30, 13Jul '13||130|
|Yoga for neck pain+ |
A small experiment (Cramer et al) optimistically concluded that Iyengar yoga helped neck pain more than a generic exercise program. But this research was too flawed to trust. Dr. Edzard Ernst was not impressed, and I entirely agree with him: “One does not need to be an expert in critical thinking to realise that… the positive outcome might be unrelated to yoga.”
|Jul 25, 13Jul '13||60|
|The placebo paradox+ |
How refreshing! A perspective on placebo that doesn’t worship the “power” of placebo, but looks instead at the paradox of placebo: if placebo is so ding dang powerful, why isn’t everyone cured? Perhaps because the placebo effect is basically a dysfunctional mistake. Here’s a video, Why does the placebo effect work? 6:01, and here’s the scientific paper it’s based on, Humphrey & Skoyles, Current Biology, 2012 — and here’s some excellent some extra reading from Seattle Rolfer Todd Hargrove, who did a nice job interpreting and explaining the scientific paper. The additional perspective is most welcome.

I’ve prepared a compilation of tales of outrageous hate mail, quotes and comics and quite a bit of whimsy and eye-rolling, the ethics and tactics of debunking, what’s it like to be an “enemy of massage,” and — my favourite — “advanced negativity,” a discussion of how cynicism is baked into science in the form of the null hypothesis.

|Noise, noise, noise!+ |
Noise, noise, noise! I am often asked about the meaning of knee noise (“crepitus”), which can often be quite spectacular — surely the loudest joint in the body. But knee noise in the absence of any other clear signs (like pain) is usually uninterpretable. It does not correlate well with problems. So you can be in trouble ... silently. And you can be fine... noisily. Rule of thumb: crepitus is only of concern if you’re also in pain, and not necessarily even then.

Intriguing: this test of 90 patients (half with neck pain, half without) showed that neck pain correlates pretty clearly with weak breathing. But is the weakness a cause? An effect? A bit of both, perhaps — if I had to guess (and I do have to guess), I’d guess “all of the above.” Both pain and weakness are probably both a cause of and an effect of the other.

|Why is back pain still a huge problem?+ |
Why is back pain still a huge problem? Here’s an articulate explanation from a new paper by Max Zusman:
Nicely said. More simply: patients believe back pain is caused by structural fragility, and therapy careers are often built on catering to that belief.
If only I could edit it, though, I would say instead that it is difficult to alter that belief in anyone, patient or professional. The overemphasis on fragility isn’t just reinforced by the practices of manual therapists, it’s the reason for many of them.

|Derpish stupidity+ |
“Derp” defined as a Bayesian probability concept: the persistent refusal to update beliefs about what is likely to be true based on new evidence.
The word “derp” originally comes from pop culture, but has come to be used most earnestly in political punditry, referring to the extreme mental ruts characteristic of American right-wing extremists. But derpish stupidity is also rampant in health care, and this more technical definition of what derp has come to mean in politics is a pitch perfect description of how quacks defend their beliefs — namely, with self-serving assumptions that are impervious to contrary data, and are literally decades or even centuries behind biology and medicine.

Overheard: a chiropractor speaking of an upper cervical treatment said to a patient, “Your neck is now in God’s alignment.” Not just an adjustment — it’s holy!

It is strange and distasteful to virtually anyone but another fundamentalist Christian.

|Spinal Nerve Roots Do Not Hook Up to Organs!+Are the little bundles of nerves that exit your spine the wellspring of all visceral vitality? Will your organs wilt like neglected house plants if those nerve roots are slightly impinged? No: cut a nerve root completely, and you’ll certainly paralyze something, but not an organ, because organs simply don’t depend on spinal nerve roots. And yet this is what many chiropractors believe, and would like their customers to believe, after a century of contradictory evidence.

As with my therapeutic touch article earlier this week, this is another topic I have little patience for, but it’s too common to entirely ignore — so here’s my brief position statement. As usual, critics need to know before commenting that I have plenty of direct experience with every scrap of pseudoscience that I now criticize.

|Failed healing+ |
Most of the time it’s hard not to heal. You couldn’t stop it if you tried — not that you’d want to. The body is going to recover from most kinds of injuries almost no matter what — it’s just a matter of time. As long as you were reasonably healthy before you were injured (and you don’t smoke or otherwise abuse your vitality), healing will usually progress inexorably.
Chronic pain is different by definition: it doesn’t stop when it’s supposed to. Either healing itself fails, or the pain continues even when the tissues are fine, or a bit of both. Overuse injuries or repetitive strain injuries (RSIs) like carpal tunnel syndrome and plantar fasciitis are slow-motion traumas that often seem immune to recovery — this is what makes them both terrible and fascinating. They are not as simple as they seem. More:

Because people cannot seem to be reminded of this enough: Human beings will get great placebo from any treatment that seems impressive in any way (more invasive, novel, unpleasant, whatever suggests potency). This accounts for most treatment success stories from both patients and professionals. Everyone should know better than to trust those stories — because it’s 2013, not 1913 — but they are still prevalent, given far too much weight, and they hijack most conversations about what works and what doesn’t for stubborn painful problems. As soon as someone says, “Well, it works for me/my patients,” that’s pretty much the end of any useful debate.

Thursday and Friday’s trouble with my e-bookstore now seems to be cleared up, but it took a solid 48 hours. Fascinatingly, the slowness of the recovery may have been due to a major hacking incident several weeks ago, which affected basic internet infrastructure: that is, the “Domain Name System” (DNS) may be damaged and/or deliberately slowed down as a security measure. The theory is that corrected information about the location of my e-bookstore took much longer (2 days) to spread around the world than it would have before (2 hours). Here’s an interesting NY Times article about the hacking incident, with good diagrams:

But the correct information is steadily spreading around the world (“Domain Name System (DNS) info propagation”), and I am fairly confident the worst is over.

The first run was a total shock, and probably an unwise spike in pavement pounding — honestly, I’m amazed I didn’t hurt myself, prone as I am to RSIs. But I got away with it just fine.

Digital rights management (DRM): it’s used by all the big publishers to limit e-book piracy … and we all hates it. You hates it, I hates it. DRM annoys customers, prevents real ownership, makes honest lending nearly impossible, locks e-books to one kind of reader … just yuck. We hates DRM! My e-books are “low DRM.” I do protect my (preciouss) books a little — but a lot less than big publishers do. In particular, it’s easy and fine to lend my e-books!

|Pain changes how pain works+ |
Pain itself often changes the way the way pain works, so that patients with pain actually becomes more sensitive and gets more pain with less provocation. This awful (and surprisingly common) phenomenon is called central sensitization. Everyone should know about this: owner’s manual stuff.

|Pain Changes How Pain Works+Pain itself often modifies the way the central nervous system works, so that a patient actually becomes more sensitive and gets more pain with less provocation. This is called “central sensitization.” (And there’s peripheral sensitization too.) Sensitized patients are not only more sensitive to things that should hurt, but also to ordinary touch and pressure as well. Their pain also “echoes,” fading more slowly than in other people. Pain itself can change how pain works, resulting in more pain with less provocation (sensitization)||Apr 16, 13Apr '13||2,500|

|Not what they seem+ |
After years of practice, I can easily find your infraspinatus muscle. In the dark, in about three seconds. Through a thick towel. However, massage and manual therapists often fool themselves into thinking they are feeling things under their hands that are not actually there, or things that might be there but cannot possibly be detected with any reliability. This is palpatory pareidolia: illusions in the sense of touch.Palpatory Pareidolia: Sensory illusions, wishful thinking, and palpation pretension in massage and other touchy health care

|Disc, schmisc+ |
Patients with back pain and sciatica recovered about equally well with or without disc herniations visible on MRI. Most people recovered (84%) well within a year … and there were actually 2% more good outcomes in the patients with disc herniations! This seems like a rather surprising result, but that is what the research has been showing for years. There is a chance the nearly identical stats are a fluke, but they’d have to be off by a lot to change the take-home message. Even a 20-point difference, ten times larger than this, would still show that a “slipped disc” confirmed by MRI isn’t nearly as worrisome as most people assume.

Updated my article about Tissue Provocation Therapies. The update was inspired by a new article by Leonard Van Gelder, a “huge proponent” of Instrument Assisted Soft Tissue Mobilization (IASTM, like Graston). It’s a decent critical review of IASTM, with some fairly harsh words, but it also rests on a foundation of classic error: certainty that a treatment really works. It doesn’t take much reading at TestingTreatments.org (see previous post) to realize that it’s actually impossible to know if a something works based on clinical observations alone. Repeat after me:
“I will not claim to know what treatments really work for pain before they are properly tested.”

|One of my favourite history of medicine stories+ |
It’s the 200th birthday of John Snow, the father of epidemiology, the science of diseases and how they spread. In 1854, Snow mapped cases of cholera and traced the disease to its origin, and proved with a simple test that it was coming from a polluted well: he removed the pump handle, and the cholera outbreak stopped. Naturally, this conclusion was scoffed at by those with competing theories (“bad air”), producing one of my favourite history of medicine stories: to prove that cholera was not in the water, some smartypants biologist drank a glass of the stuff … and got away with it, because he just happened to be immune. It’s a great example of why “experience” is not trustworthy, and why it takes so long to settle even relatively straightforward puzzles in medicine.

Why am I so “negative”? I am often asked this. There are many answers, and the most important has always been that I value truth-telling in health care for its own sake, even if it’s disappointing, and unfortunately a lot of it is.

Pelvic tilt is one of the great biomechanical bogeymen, one of those things that gets blamed for a lot of pain and is the justification for a lot of massage and chiropractic therapy. I was taught in school to judge pelvic tilt by measuring the pointy bits. It all seemed very technical. And yet, as I always suspected, pelvic shape is simply much too variable to diagnose pelvic tilt by feel. The shape can vary as much as the position! A new study of cadavers “found that the PSIS/ASIS angle varied from left to right (up to eleven degrees), even when the pelvis was in neutral. The asymmetrical shape of the pelvis in this respect could make it appear that one side is rotated forward compared to the other.” That’s from a superb report on the study by Todd Hargrove at BetterMovement.org:

|Thixotropy is Nifty, but It’s Not Therapy+Thixotropy is the property of some gels or fluids that are normally thick (viscous), but thin when they are stressed. In the human body, the synovial fluid that lubricates most joints is thixotropic, as is the gelatinous “ground substance,” which is part of all connective tissues such as tendons and ligaments. (Fun fact: semen is also thixotropic.) Thixotropy is one of the reasons that we loosen up a little as we move around, just like engine oil warming up. However, thixotropic effect is not a therapeutic effect, and does not explain “releases” in massage or fascial therapy: it is too minor, slow, and temporary, and connective tissue is too tough.

I lean towards “not enough.” Best criticism of my posture article so far? I don’t mention potential for nocebo & unintended consequences of advice [Now corrected]. Belief in postural dysfunctional can probably drive a nocebo + spinoff beliefs about vulnerability + harmful zeal for “correction.”
|Feb 11, 13Feb '13||75|
“Posturology” is the cheesy, popular term for the mostly made-up “discipline” of studying the relationship between posture and pain, and even diseases. Posturologists (I can barely write that with a straight face) tend to assume their own conclusion: they just take it for granted that poor posture does cause pain and then look for confirmation. 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 (see Guimond et al for a good example) and “posturology” is mostly a slummy pseudoscientific research backwater. There may actually be something to learn, if only posturology research was better quality, but most of it has to be just chucked or at least taken with a huge grain of salt.

You can’t very well treat core instability if you can’t diagnose it as a problem in the first place. This test of the reliability of core strength testing was a clear failure: “6 clinical core stability tests are not reliable when a 4-point visual scoring assessment is used.” Even if core strength is important (a separate question), this evidence clearly shows that no one should be claiming to be able to detect a problem with core weakness in the first place. A bit problematic for core dogma.

|Popular but Weird and Dangerous Cures+
The colorful history of medicine and quackery is overflowing with people who “swore by” treatments that were bizarre and dangerous. Bloodletting was popular almost until the 20th century, despite being relentlessly harmful. Some of the most lethal “cures” in history were inspired by the discovery of radiation. People happily drank metals like mercury and silver. Even drinking urine had near fad status for a while! They tried to purge disease with sulfuric acid, and stimulate their vitality (and virility) with powerful electric shocks. Women were sold Lysol as a douche … and women actually went along with it for a while. Voluntary lobotomy may be the craziest of them all: it was a popular treatment for all kinds of psychiatric disorders, and at least fifty thousand people volunteered to have their brains lanced.
All of these terrible treatments, and many more obscure examples, had many fans and enthusiastic testimonials. People paid for them, believed in them, loved them, swore by them — that is how misleading testimonials can be. People believe what they want to believe.The most dangerous, strange, and yet popular snake oils and “treatments” in history (and why anecdotes and testimonials cannot be trusted)

Static stretching vs. “fancy” PNF stretching: which works better? Hold-relax, right?
It’s common for stretching enthusiasts to dismiss my concern that stretching is not all that useful with the concession that, of course, static stretching is quite pointless, but fancier methods (their methods) are “obviously” clinically useful. By far the most common example of allegedly superior stretching is the broad category of “proprioceptive neuromuscular facilitation,” and more specifically the hold relax method. Supposedly this approach works better than mere pulling on muscle. However, this test of the immediate effects HR-PNF versus static stretch on hamstrings was a bust: they both increased flexibility equally well (for whatever that’s worth).

It originated with “one of the classic mistakes in the history of science,” according to George Brooks, a Berkley physiologist. See Gina Kolata’s clear overview in the New York Times, or a concise professional summary by Robergs in Experimental Phsyiology. For a deeper and geekier, but excellent read, see Dr. Goodwin’s entertaining rant about the prevalence of the lactate myth in the 2012 summer Olympics coverage.

|When To Worry About Shortness of Breath … and When Not To+Difficulty breathing is a common complaint and a tough diagnostic challenge, and there are some serious causes to be aware of. However, many cases are probably caused by minor and treatable muscle knots, respiratory dysfunction and/or weakness. Relief may be relatively easy for some patients. It’s safe and cheap to experiment with self-massage for muscular trigger points. And, although changing bad habits is always tricky, increasing your respiratory strength is definitely effective and a worthwhile fitness goal in any case.

|Electromagnetic Sensitivity Absurdity+
Electrosensitivity is an alleged allergy to electromagnetic fields and radiation. It is the basis for paranoia particularly about the health effects of Wi-Fi networks, power lines, and cell phones — fears that top the charts of human irrationality. There’s little doubt that the afflicted are suffering from something, but it is either an unrelated medical condition or psychosomatic. Electrosensitivity, like (non-celiac) gluten sensitivity, has been thoroughly debunked.
Unsurprisingly, many people who believe they can heal with life energy — reiki, acupuncture, and so on — are also active spreading fear, uncertainty, and doubt about artificial energy.
No one with an actual energy allergy would last a day anywhere in the modern world. It would be an electrosensitive holocaust. They’d vanish in a poof of oversensitive smoke, moths flying into a bonfire.Electrosensitivity is an imaginary, debunked energy allergy

Homeopathy is a 200-year-old medical philosophy that has been thoroughly debunked, and survives today thanks to wishful thinking, ignorance, and because it is too useless to be very dangerous. It is the flagship in the alternative medicine fleet: the most profitable, absurd, and snakey of all snake oils.
Most people have no idea just how strange homeopathy is. The deal-breaker for many consumers is the discovery that it’s not just an “herbal” or “natural” remedy, but a “magical” one, based on a principle that reeks of flaky physics and old-timey snake oil flamboyance—much farther out in left field than herbs. Some people, of course, are quite happy citing quantum physics to explain alternative medicine, but you really have to be a card-carrying new age sort to go there. For most people, that crosses a line.
But they have to find out first! Fortunately, doctors, scientists and skeptics are unanimously and harshly critical of homeopathy, and have published many good quality critical reviews. For instance, see my own article about homeopathic arnica — the most popular of all homeopathic products, intended to treat inflammatory pain.Homeopathy is not a natural or herbal remedy: it’s a magical idea with no possible basis in reality

|Typos & Nitpicking Hypocrisy+
Whenever I make criticasms of sloppy writing, I do open myself up to a charge of hypocrazy, because there are certainly scattered errrs on my website , probbly even on this veru page. But it’s a matter of dagree. I only critisize someone’s communiation skills when their writeing problem are signicifant and revelant: when the errors are thick and nasty and thick and nasty, when they arre combimed with style problems like SHOUTING IN CAPS!!!, or abusing “quotion marks”; or just horrible spellung and grammer and sentense structure, and and whn they betray ignoranse of the subjet matter,, like a chiropracor who writes the “veterbra” three times in the same short email and declares “I’m a proffesional”.
(I’m not making that last bit up. I actually got that message.)
Not everyone’s a writer, but writing with many glaring errors is much worse than just lacking a knack — and it exposes a lack of mental rigour and maturity. There is such a thing as a minimum literacy required for one’s ideas to be taken srsly.
