Has a coach, trainer, or therapist “screened” you for injury risk and dysfunctional or performance-limiting movement patterns? The Functional Movement Screen (FMS) is a set of seven physical tests of coordination and strength, especially “core” strength, invented in 1997 and now in widespread use around the world. It was originally proposed as a trouble-detection system, which is baked into the name: it’s a “screen.”
Its use in the wild seems to over-reach this stated purpose.
FMS founder Lee Burton wrote in March, “The biggest critique we have gotten over the years is the lack of research to support use of the FMS” but “more and more research is becoming available relating to its scope and effectiveness.”1 I am not so sure that the evidence available to date is persuasive — the opposite, I fear — but meanwhile FMS is being promoted as though its powers are proven. Despite Burton’s statement, I think the marketing cart may be in front of the research horse — as so many carts are in the world of training and musculoskeletal health!
This isn’t a thorough review of FMS per se: it is focused on the abuse of FMS as a way to diagnose the average athlete or patient (or the closely related SFMA, which is actually advertised as a “movement based diagnostic system”). However, these concerns do cast doubt on the validity of FMS in general, as well as the much broader idea of corrective exercises, which need problems to correct, such as core weakness or “poor posture.” If FMS has problems, then probably so do simpler ideas about what needs fixing.
Functional Movement Screening in theory
“To date , there is no intervention study providing support for screening for injury risk.”
Bahr, 2016, British Journal of Sports Medicine2
A “screen” has a specific meaning in health care. It is not a diagnostic tool: it is just for detecting individuals who need diagnosis. This is a common concept in health care — think “mammogram” or “prostate exam”3 — but not so much in sport and rehabilitation. The complexities and ethics of screening are a bit exotic, normally debated in the context of vast public health initiatives.
Anoop Balachandran explains how screening is fundamentally a different ethical beast than diagnosis, because you are telling basically healthy people what might be wrong with them, and that raises the stakes4 (specifically the real risk of nocebo5):
… The validity of screens should be of the highest quality since you are “labeling” people and hence we should have very solid proof that people will be better off in the long run. When someone scores less than the cut off in the FMS, you tell them their chance of getting injured is extremely high. This is a great way to get someone to move less or have fear of movement or spend his or her time and money trying to fix it with their trainer.

Nevertheless, it was a fine idea to try to introduce FMS into the world of performance and rehab. It would have been a good idea even if that was not the actual original intent. Truly, we could use a good screen. It’s just not clear that FMS is actually being used that way. Indeed, it’s seems clear that it’s not.
Functional Movement Screening in practice: a diagnostic tool?
The FMS is officially not meant for assessing people who are already hurting or injured, just “limitations” and risk factors for injury. And yet the people that gave us FMS also teach a closely-related but much less well-known “movement based diagnostic system,” the SFMA. Whatever it’s called, professional are definitely diagnosing based on movement, one way or another — either abusing the concept of FMS, or using SFMA as intended.
So either FMS should change its name, or it should actually only be used as a screen — only to establish that “something is wrong here” or “something is still wrong here” — and not to figure out what is actually wrong. But in the real world, FMS is often promoted as a tool that can “detect” biomechanical problems and therefore justify training or treatment methods to “correct” them. Again, founder Lee Burton: “FMS is designed to identify movement pattern dysfunctions, thereby helping create the best possible intervention.”6
That’s no screen — that’s diagnosis!
And the “best possible intervention” is often expensive, of course. Athletes and sports teams may invest heavily in following advice that is based substantially on FMS assessments.
FMS certification and exaggeration of its benefits is also often used to create an impression of diagnostic competency in professionals — coaches and trainers — who are trying to seem more like therapists and should not be diagnosing at all (or even seem to be). Athletes and fitness buffs are often “enablers” in this regard.7
This is a general problem with the industry, of course, but FMS certification is a prominent example.
A little searching on the internet can quickly scare up examples of FMS being used diagnostically. In just a few seconds, I found a chiropractic website with the claim that FMS “uncovers limitations and asymmetries in the movements of healthy individuals.” It goes on “Corrective exercises can then be prescribed to overcome these deficiencies.”8 The overconfident use of FMS to justify specific treatment is blatant here.
Or look at this amusing example of overconfident promotion of FMS: big diagnostic and treatment promises, to the tune of cheesy 80s rock anthem “Eye of the Tiger.” (Admittedly, it’s a nostalgic classic. My foot taps … ) In the video, modestly titled FMS: Get Your Best Body, a chiropractor demonstrates FMS and explains:9
Depending on your score and asymmetrical results from left to right side I can determine your non-painful dysfunction. We correct that and you become a better athlete. Stronger, more flexible, stable, mobile and powerful. Oh, and you can get out of chronic pain…
Are these just isolated cases of FMS hype? Perhaps FMS training and certification would minimize such overstatement? Perhaps. There may well be FMS practitioners who overstate the claims of FMS, going beyond its intended use. But FMS certification is granted by a company that promotes it with language surprisingly similar to the examples above. The official FMS website is generally heavy with promotional language and light on the science:10
… the FMS readily identifies functional limitations and asymmetries … used to target problems … directly linked to the most beneficial corrective exercises to restore mechanically sound movement patterns … identify those exercises that will be most effective to restore proper movement …
“About” page of FunctionalMovement.com11
Visit the FunctionalMovement.com, have a look around, and judge for yourself. Does it seem like they are promoting a screening tool with modest goals and appropriately limited scope? Or a diagnostic tool “directly linked” to treatment?
The Functional Movement Screen fails to detect recent injury
The use of FMS as a screen and a diagnostic tool has been particularly problematic because “normal” test results had never been defined. A low FMS score supposedly means that you are more likely to get hurt, but … lower than what? FMS needs a baseline — or even several of them, for a variety of well-defined populations.
A 2011 study in International Journal of Sports Physical Therapy set out to get the numbers for normal.12 According to Schneiders et al the idea that FMS has diagnostic power is (emphasis mine):
… based on the assumption that identifiable biomechanical deficits in fundamental movement patterns have the potential to limit performance and render the athlete susceptible to injury.
However, their experiment could not even detect a difference in test results in people who had actually been injured recently. The results
demonstrated no significant differences on the composite score between individuals who had an injury during the 6 last months and for those who had not.
Past injury is probably a risk factor for future injuries — for instance, the reasons for the original injury may persist and cause re-injury, or a new injury. If FMS cannot detect any sign of recent injuries, it seems unlikely that it can detect the risk of future injuries, let alone be used as a basis for a specific therapy.
This is not surprising. In general, rehab science has generally been failing for decades to nail down correlations between even the most obvious-seeming “biomechanical bogeymen” and common injuries, let alone the smoking gun of a true cause. Even if there are biomechanical causes of pain and injury — and doubtless there are a some — I wouldn’t expect a set of physical tests to reveal them in an exact or reliable way.
Anoop Balachandran criticizes the rationale for FMS in more detail:13
Why should mechanical stress causes by “faulty movement patterns” always “lead to microtrauma and injury”? Why can’t tissues just positively adapt and get stronger just like a normal biological tissue? If indeed faulty movement patterns were the cause of injury, all those cerebral palsy patients, stroke victims, people with neurological disorders and amputees should be in complete pain. There are double amputees who run faster than most of us and still feel no pain. The compensations and asymmetries are 100% in these amputees and they should be crying out loud in pain than running around. Maybe that movement pattern is “ideal” for them and the tissues have adapted to it.
Anoop Balachandran, MSc Exercise Physiology, MSc Human Performance
A long, fragile chain of reasoning
FMS is classic example of structuralism — the excessive preoccupation with biomechanical factors in injury and pain.16 In particular, it depends on the faddish notion that “core strength” is important, an idea that has been harshly criticized by experts17 and has generally failed to live up to its reputation.18 At best, the value of core strength remains controversial. At worst, it’s been a serious red herring in the fitness and therapy industry.
Structuralism typically depends on complex chains of reasoning that are only as strong as their weakest links. For FMS to deliver what it promises, all the of the following links must be sound:
- Non-obvious functional limitations must be consistent signs of “dysfunction.” If they are …
- Subtle dysfunction must in turn actually be a cause of injury and limited athletic performance. This theoretetical foundation highly controversial and complex. But even if it’s solid … which is a huge if …
- FMS practitioners must be able to reliably detect the existence of specific non-obvious functional limitations. schneiders11 et al. found that this link is okay. If it really is …
- FMS practitioners must be able to reliably associate those functional limitations with a much more complex array of potential problems that could be causing them. Here again we see the problem with the difference between screening and diagnosing. Perhaps anyone can be trained to spot poor performance on FMS tests. But can anyone identify the cause of that poor performance? What if it’s an early sign of a slow-developing neurological disease? Diagnosis is a vastly more complex beast than screening. If FMS practitioners can diagnose reliably …
- The identified dysfunctions must actually be correctable in principle. A basic problem with many biomechanical theories of pain is that, even if true, there’s nothing that can be done about them. If they are correctable …
- The FMS practitioners must then be able to reliably prescribe appropriate correction.
If FMS practitioners can do all that — and do it reliably — then they can deliver what they are promising.
2020 update: Is the FMS science here yet?
It’s trickling in. There’s probably enough for some tentative conclusions now.
The first version of this article was written in 2011, mostly hype-griping, and it went untouched for three years while FMS promoters carried on making claims about a “growing body of research,” of course. The research wasn’t persuasive before, and maybe things have gotten worse since.
A summer 2014 paper by Whiteside et al echoes all my original concerns, but with harder data.19 The researchers focused on the accuracy of FMS grading in particular: “virtually no investigations have probed the accuracy of FMS grades assigned by a manual tester.” So they probed it! They compared “the FMS scores assigned by a certified FMS tester to those measured by an objective inertial-based motion capture system.” Alas for FMS, the results were “poor,” which is exactly what I’ve been betting on all along.>
Manual grading may not provide a valid measurement instrument. The levels of agreement between the two grading methods were poor in all six FMS exercises. It appears that manual grading of the FMS is confounded by vague grading criteria.
The discussion section of the article is detailed, readable, and full of ominous understatement. “Dubious grading presents a concern for FMS clientele,” they write. They graciously allow that, with better objective criteria, FMS grading might “improve to acceptable levels.” Meanwhile, FMS testers are officially encouraged to aim for lower scores when in doubt, but in this test, even under scrutiny, apparently they didn’t have much self-doubt, consistently scoring “0.54 points higher than the IMU system.” (I’m shocked, simply shocked, to learn that FMS practitioners might be a tad overconfident!) The authors also point out that FMS has not only failed to reliably forecast injuries, but all FMS predictions may be “a product of specious grading.” Which is hardly surprising, since FMS fails to take into account “several factors that contribute to musculoskeletal injury.” These concerns must be addressed “before the FMS can be considered a reliable injury screening tool.”
Clearly more research is needed — of course! Naturally! But it’s worse than that:
The high potential for subjective and/or inaccurate grading implies that standard procedures must be developed before FMS performance and injury rates can be conclusively studied.
Before it can be studied. They seem to be saying that not only is the cart is still in front of the FMS horse, the horse may now be falling well behind. FMS research so far may be a bit of a write-off, because it can’t inform us without better criteria, and everyone should probably just go back to the drawing board and try again. Which suggests that this article is still reasonably sound after three years without an update.
Despite these limitations, a wave of research produced enough data to be worth of review by 2015.
The first research review
The first review of the predictive validity of FMS was published in late 2015, with a predictably and resoundingly negative conclusion based on generally mediocre data from seven studies:20
Based on analysis of the current literature, findings do not support the predictive validity of the FMS. Methodological and statistical limitations identified threaten the ability of the research to determine the predictive validity of FMS.
And another not-positive review
A 2016 review in the British Journal of Sports Medicine surveyed 17 “mostly low quality” studies of the relationship between leg injuries and movement quality, concluding it is “inconsistent.”21 In other words, we still have no idea if we can tell who’s going to get leghurt based on screening people for quality-of-movement trouble. Standard caveats about garbage-in-garbage-out reviews seem to apply here: the results are officially inconclusive, but the absence of a clear positive signal is damning.
Since that review, a good quality study in British Journal of Sports Medicine has reinforced all the negative results:22 screening results of a few hundred soccer players were not associated with lower limb injury, and could not even distinguish between injured and uninjured players. As one of the authors put it, “Any way we sliced it, Functional Movement Screening was no help in predicting injured football players.”
Not so positive after all
A 2017 study loudly, over-confidently declared in its title that “scapular dyskinesis [“bad” shoulder movement] increases the risk of future shoulder pain by 43% in asymptomatic athletes.”23 This seems to defy skepticism about the importance of scapular dyskinesia — and therefore the value of screening for it. And it was cited that way by FMS proponents.
But the headline is extremely misleading. This is a great example of lying with statistics: it’s only a 43% greater relative risk, relative to a small total count of injuries. The difference in absolute risk is very minor, and the authors concede in the body of the paper that “screening for scapular dyskinesia is not a useful approach to predict shoulder pain.” Many shoulder problems almost certainly are not announced by subtle scapular movement issues. For instance, frozen shoulder is a strange but common condition with metabolic roots, and probably there isn’t the slightest reliable clue that it’s coming before it does.
Pain and the FMS
The FMS is designed to screen for movement quirks in healthy people, but what about the role of pain? People often have aches and pains, and athletes often have more than their fair share and routinely play and compete with fairly significant ongoing episodes. How does pain affect movement, and therefore how does it affect FMS score?
A 2020 paper in Journal of Orthopaedic & Sports Physical Therapy looked at this relationship.24 The researchers subjected more than 400 young Australian footballers to FMS testing, adjusting the scoring based on pain during the test for some of them in a couple different ways, or not at all. 170 of them had pain, and their pain did affect FMS scores to some extent… but regardless of how pain was factored in, FMS scores did not predict injury risk.
And so FMS falls gain. Still.
Pain did predict injury, though — not much, but a little bit. Imagine that!
FMS simply does not do what so many practitioners claim it can do, or act like it can do. Who is going to get hurt probably just cannot be divined from subtle movement quirks. You can generally diagnose people on standardized movement screen. It is just not a thing. There are no injury risk whisperers, no one who can figure out what’s wrong with wounded athletes just by watching them put on a little movement show.
I cannot conclude that FMS has no value when used as intended and humbly. All I can do here is raise a concern that the FMS is being applied inappropriately by many trainers, and seems to be resting on a number of questionable and untested assumptions. And now, from 2015-2020, their claims are ever more at odds with the science.
So please: take it with a huge grain of salt if anyone tries to tell you what’s wrong with you, or how you might get hurt, based on FMS testing.
I’ll give the last word to Tumminello, Silvernail, and Cormack, from their excellent article on this topic in Personal Training Quarterly:25
It is often assumed that identified so-called “dysfunctions” in posture, movement quality, or body function are reliably predictive of potential injury and performance, the preponderance of the scientific evidence casts a great amount of doubt on any claims about the strength and reliability of such relationships. This is because natural variations in human posture, movement and mobility/flexibility make identifying strict ideas of what is “correct” difficult and possibly invalid in many cases. Humans naturally move in different ways to accomplish different tasks, and identifying small variations in that movement as a “dysfunction” may not be very useful or helpful.
Worse yet, it could be harmful:
patients/clients with beliefs about their body that center on fragility/risk of harm, the importance of appropriate posture, or the need to move in specific ways to avoid injury are more likely to have pain and less likely to recover from a future problem.26 That is the opposite of the kind of physical and psychological resiliency that personal training is designed to build.

- Both of these well-known and little-loved procedures are used to flag individual who need further assessment. In no way can a mammogram or prostate exam actually diagnose. The distinction is clear in these cases. (Note: in Canada, we have screening mammograms; in other countries, they are used used diagnostically. So perhaps it isn’t the best example for an international audience. But is also just another way of emphasizing the difference between screening and diagnosing.)

“Nocebo” is roughly the opposite of placebo: harm powered by belief, instead of relief.
Latin for “I shall harm” (which I think would make a great supervillain slogan). It refers to the harmful effect of … nothing but the belief in or fear of a harmful effect. Give someone a sugar pill and then convince them you actually just fed them a deadly poison, and you will probably witness a robust nocebo effect. A common funny-if-it’s-not-you nocebo in general medicine is the terror of “beets in the toilet”: people eat beets, and then think there’s blood in the toilet, and call 911. Nocebo is a real thing, and not to be messed with. It is one of the chief hazards of excessive X-raying and MRI scanning, for instance: showing people hard evidence of problems that often aren’t actually a problem.
A screening test that reveals alleged problems might do it too.

- It’s truly amazing how much credit amateurs will give to medically unqualified and barely-regulated professionals like trainers, fitness instructors, and coaches. It can be difficult for a personal trainer, for instance, to resist the temptation to answer a question as if they have the knowledge that a client wants to give them credit for. My mother is a fitness instructor, and routinely amuses me with tales of the questions that class participants will ask her in all earnestness: real medical questions! Admirably, she refuses to even speculate, and decivisely refers them to actual health care professionals — which is exactly what a fitness instructor should do.

Tumminello, Silvernail, and Cormack decisively but gently and diplomatically tip over this most sacred cow of personal training and therapy: corrective exercise, which is based on the idea that there is something in-correct about patients — fragile, weak, or uneven — which can be both identified and fixed by specific, expertly prescribed exercises, mainly strengthening and stretching exercises, the staples of stereotypical physical therapy. The trap is the belief that this “technical” approach is inherently superior to good exercise in general.
The danger here is that many fitness professionals might end up making their training process more about a formalized evaluation procedure and less about good personal training. …In order to spot a physical flaw that needs to be corrected, one must begin by having a reliable measure of whether or not it is actually problematic in the first place.
Spoiler alert: there is no such reliable measure! Corrective exercise is built on wishful thinking. Screening for movement dysfunctions has been failing one fair scientific test after another. The importance of posture has been wildly exaggerated. The importance of anatomical variation has been virtually ignored.
These authors all have excellent credentials and top notch clinical reasoning skills. These are smart guys tackling several thorny sub-topics like postural dysfunction, movement dysfunction, core stability, and — most important of all, I think — the “nocebo concerns” with corrective exercise: “when clients are told such things about themselves from an authority figure (as they might be during some corrective exercise evaluations), that this potentially makes one’s clients less resilient and more prone to injury and pain.”
Translation sans diplomacy: stop #%&^ telling patients they are fragile and weak!

This experiment compared direct measures of athletic performance like sprinting speed and vertical jump with less direct measures like maximal squat strength (the most they could lift in one squat) and even less direct measure like scores on the functional movement screen (FMS). In theory, FMS testing can predict athletic performance. In practice, in this test, it did not “relate to any aspect of athletic performance.” But squat strength did!

This study tested two popular exercise options for chronic low back pain — core coordination, core strengthening — and compared them to a neutral third type, general exercise. Over a hundred participants worked with “experienced physical therapists” once a week for eight weeks. This is a particularly good test, because it is a good approximation of what a motivated patient might do: paying for eight weekly sessions of training is a greater and more disciplined effort than many people make, and yet still reasonably affordable and achievable.
Pain and disability were measured before and after, and at a one year follow-up. Unfortunately, there were no differences: “This study gave no evidence that 8 treatments with individually instructed motor control exercises or sling exercises were superior to general exercises for chronic low back pain.”
Perhaps more training would have yielded better results, but it’s hard to imagine that it would be worth the additional expense and effort for what would surely be a minor difference. And perhaps a different exercise therapy would have performed better, but the ones tested here are exactly the kind of thing that is almost always recommended to patients — so if there’s a better kind of exercise therapy, it’s certainly unknown and unproven.

OBJECTIVE: To describe the location and severity of pain during Functional Movement Screen (FMS) testing in junior Australian football players and to investigate its effect on FMS composite score and injury risk.
DESIGN: Prospective cohort study.
METHODS: Junior male Australian football players (n = 439) completed preseason FMS testing. Pain location and severity (on a 0-to-10 numeric pain-rating scale [NPRS]) were assessed for painful subtests. The FMS composite score was calculated using 3 scoring approaches: "traditional," a score of zero on painful subtests; "moderate," a score of zero on painful subtests if an NPRS pain severity was greater than 4; and "raw," did not adjust painful FMS subtest scores. Players were monitored throughout the competitive season and considered injured when 1 or more matches were missed due to injury.
RESULTS: One hundred seventy players reported pain during FMS testing. The pain-scoring approach affected mean composite score values (raw, 14.9; moderate, 14.5; traditional, 13.6; P<.001). Sixty-eight percent of pain was mildly severe (NPRS of 4 or less). Back pain (50%) was more common than upper-limb (24%) or lower-limb (26%) pain (P<.001). Upper-limb pain was associated with a small increase in injury risk (hazard ratio = 1.59, P = .023). No other FMS pain location influenced injury risk, nor did pain severity (P>.280). The FMS composite score was not associated with injury risk, regardless of pain-scoring approach (P≥.500).
CONCLUSION: Pain was common during FMS testing in junior Australian football players and had a notable effect on the FMS composite score, but minimal effect on subsequent injury risk.
