Here's why you can't say a "Movement Dysfunction" causes a Specific type of Injury. Sorry. #shorts

"Movement dysfunction" gets thrown around like it's a diagnosis.
It's not.
It's an observation dressed up as hidden treasure.

The trouble is, that at face value, linear thinking like this makes sense...

Structure determines function
dysfunctional structure is from dysfunctional movement
therefore,
dysfunctional movement causes injury.

Clean, linear, satisfying.
Also, mostly fiction.

Start with structure.
Human morphology is wildly variable across populations, genetics, bone structure, limb ratios, joint architecture.
There is no universal 'Normal' structure to measure anyone against.

Now function.
Watch ten different elite 100m sprinters.
You'll see ten different movement strategies...
different arm carriage, different stride lengths, different foot strikes
all of them "elite"

Elite function isn't one blueprint.
It's a wide range of valid solutions to movement problems.

So if structure varies that much,
and function varies that much even at the elite level...

Where exactly is the line where something becomes "dysfunctional?"

Let's be honest about the answer...
Most of the time, that line gets drawn the moment pain shows up.
Not before.

Pain enters the conversation, and suddenly the movement pattern that existed unchanged for years gets retroactively relabeled as "the problem."

That's not how applied biomechanics should work.

That thinking works for a car... consistently machined parts (structure) build the same every time, to perform a certain task (function) when the part breaks, we can cleanly deduce the cause.

For humans, the foundation isn't solid enough to support that conclusion, even though it gets stated as fact in clinics every single day.

So here's what I do instead of hunting for dysfunctions to label.
Instead of looking for what's "wrong" with how someone moves.

I look for the opportunity in their equation...
the adaptations that, if made, would be favorable for their pain, sport, and goals.

Less "let's fix your dysfunction."
More "let's fill in your deficits"

One of those treats the athlete like a problem to be corrected.
The other treats them like a system to be optimized.

Which one sounds better to you?
