Ever wonder why some injury-prediction tests look great in the lab but fall apart on the field? The Functional Movement Screen (FMS) has been pitched as a crystal ball for who's about to get hurt. But a 2014 study published in the Journal of Strength and Conditioning Research — often shortened to the FMS NSCA JSCR 2014 paper — threw a bucket of cold water on that idea And that's really what it comes down to. Nothing fancy..
I've read the full text more than once. And honestly, the efficacy of the functional movement screen nsca jscr 2014 summary is something every coach, athlete, and parent on a sideline should understand before they trust a score out of 21.
Here's the thing — most people hear "screen" and assume it's a diagnostic. Day to day, it isn't. Let's dig in.
What Is the Functional Movement Screen
The FMS is a battery of seven movement tests. You squat, lunge, reach, and twist. Also, each gets a 0 to 3 score. So add them up, and you get a number out of 21. The pitch from early advocates was simple: low score, high risk. Fix the movement, lower the risk.
But the screen was never built as a medical exam. It's a filter. A quick way to see if someone moves like a rusty hinge or a well-oiled door. That distinction matters, because a filter is not a verdict Not complicated — just consistent..
Where the FMS Came From
It was developed in the early 2000s by physical therapists working with athletes. It was to flag asymmetries and crappy patterns before they became problems. Consider this: smart idea. The goal wasn't to diagnose injury. The problem is what happened next — people started treating a 14 as a death sentence for a season.
What the 2014 Study Actually Looked At
The efficacy of the functional movement screen nsca jscr 2014 summary comes from a specific cohort. Also, they recorded FMS scores in preseason. That's why researchers tracked professional American football players through a season. Then they watched who landed on the injury report And that's really what it comes down to. Still holds up..
The design was solid. Large sample, real-world setting, defined injury criteria. That's why the results hit harder than a blog post with a hot take.
Why It Matters
Why does this matter? Because teams were spending money and practice time on screens that might not do what the brochure claimed. If a test can't predict who gets hurt, you can't use it to prevent injuries. You're just collecting numbers That's the part that actually makes a difference..
Turns out, the 2014 paper found no significant relationship between composite FMS score and injury risk in that football population. A guy scoring 18 wasn't meaningfully safer than a guy scoring 12. That's a big deal when the whole selling point is risk stratification.
And here's what most people miss — the study didn't say movement quality is irrelevant. It said this specific tool, in this specific population, didn't predict injuries the way we hoped. Context is everything Small thing, real impact..
The Cost of Misplaced Trust
Real talk: when a college program bases training modifications on a screen with weak predictive value, they might ignore other factors that actually matter. Also, sleep, load management, previous injury history. Those have stronger evidence than a deep squat score.
How It Works (or How to Read the Study)
Let's break down what the researchers actually did, because the method is where the truth lives.
The Scoring System
Seven tests: deep squat, hurdle step, in-line lunge, shoulder mobility, active straight leg raise, trunk stability push-up, rotary stability. Each scored 0 (pain), 1 (compensated), 2 (okay), 3 (clean). Max 21 Which is the point..
A common cutoff in practice was 14. Below that, you were "high risk.Worth adding: " The JSCR 2014 paper tested that cutoff. It didn't hold up.
The Population and Follow-Up
They used NFL players — elite, strong, fast, and already filtered through years of selection. But that's a narrow group. Injury definition included time-loss events. They tracked the whole season That's the part that actually makes a difference..
The short version is: they compared injury rates across score bands. No band was safer enough to matter statistically.
What the Stats Said
The authors ran regression models. They adjusted for position, age, and history. Consider this: the composite score was not a useful predictor. Some individual test flaws showed tiny signals, but nothing you'd bet a roster on That's the part that actually makes a difference..
I know it sounds simple — but it's easy to miss that "no relationship" in a room where everyone already bought the FMS certification And that's really what it comes down to. That alone is useful..
Common Mistakes
Most guides get this wrong: they either worship the FMS or bury it. Both miss the point Small thing, real impact..
Mistake 1: Treating the Screen as Diagnostic
A 9 out of 21 doesn't mean your knee is broken. It means your movement pattern is noisy. Using it to pull an athlete from play without other evidence is overuse But it adds up..
Mistake 2: Ignoring the Population Gap
The efficacy of the functional movement screen nsca jscr 2014 summary is about pro football players. Which means apply that to a 12-year-old soccer team and you're guessing. Generalizing from one study to everyone is lazy thinking Small thing, real impact..
Mistake 3: Cherry-Picking the Composites
Some later papers found links in different sports. Fine. But people cite those and ignore the 2014 JSCR paper like it didn't happen. Still, you have to hold both. The screen works better in some places than others — and we still don't fully know why But it adds up..
Mistake 4: Assuming Zero Means Useless
The 2014 study killed the predictive myth. As a conversation starter about movement, it's still a decent mirror. It didn't prove the FMS can't help coaching. Just don't sell it as a shield Simple as that..
Practical Tips
So what actually works if you're a coach or athlete who still likes the FMS?
Use It as a Baseline, Not a Verdict
Score someone in week one. Re-score in month three. Did the number move because training helped? That's useful feedback. Did it stay low but the athlete stayed healthy? Then the score wasn't the story.
Pair It With Real Risk Factors
Previous injury is the best predictor we have. Here's the thing — sleep and stress matter. But training load spikes matter. Put the FMS in that pile — not above it.
Don't Waste Practice Time Over-Fixing
If an athlete scores 13 and has no pain, don't burn 20 minutes a day on corrective drills. Which means the efficacy of the functional movement screen nsca jscr 2014 summary tells us the score won't save them. Now, watch them. Train them. Good programming might.
Read the Damn Paper
Seriously. The abstract is free in places. The full JSCR 2014 article is clearer than most summaries online. You'll see the confidence intervals and understand why coaches got quiet after it dropped.
FAQ
Does the FMS predict injury in athletes?
In the 2014 JSCR study of NFL players, the composite score did not significantly predict time-loss injury. Other studies in other groups show mixed results, so it's population-dependent Most people skip this — try not to..
What is a good FMS score?
Out of 21, early users flagged 14 as a line. But the 2014 paper showed that cutoff didn't separate risk well in pros. "Good" depends on your sport and health, not just the number And that's really what it comes down to. Turns out it matters..
Is the Functional Movement Screen still used?
Yes, many coaches use it for movement conversation and tracking, not for injury prediction. The efficacy of the functional movement screen nsca jscr 2014 summary shifted how it's framed — less crystal ball, more mirror.
Should youth coaches use the FMS?
Carefully. Kids move weird because they're growing. A low score might just mean "not finished baking." Use it to teach, not to label.
What predicts injury better than the FMS?
Prior injury history, sudden load increases, poor sleep, and sport demands. Those beat a squat score in most research Most people skip this — try not to..
The FMS isn't evil and it isn't magic. The 2014 JSCR paper just reminded us to stop asking a 7-test screen to do a full medical's job — and to actually watch the humans in front of us instead of the numbers on the sheet And that's really what it comes down to..
