We've built MSK around things we can measure. Straight edges and 90-degree corners.
Range of motion. Strength. Numbers that move so we can point at them and say "look everyone, it's working." The patient might feel exactly the same but the graph looks better.
And we all know how easy it is to "find" strength. A bit more grunt on a dynamometer, a bit more encouragement, a slightly different setup and suddenly they're stronger. Looks very objective. Smells robust. Keeps everyone comfortable.
Here's the bit people don't like.
Being weak doesn't automatically mean you're in pain and getting stronger doesn't guarantee it goes away. Yet we default to loading people up because strength is neat, measurable and defensible.
Control isn't.
You can't stick control on a graph. It's subjective, experience-driven and it shows up in how someone actually moves when it matters. Put someone in front of a mirror or film them on an iPhone and they'll see it within seconds.
That takes a different kind of work. More time. More observation. More conversation. More trust. Less hiding behind numbers.
After a long time doing this, the shift for me has been simple: I spend far less time chasing strength in isolation and far more time challenging how people use it in function.
Because most patients don't need more horsepower. They need better cornering skills.
Muscles are easy to train. Movement is harder and that's the bit that matters.
Call it control. Call it stability. Call it what you like. I know some people twitch when they hear those words, just like they do with half the labels we've created over the years.
Fine. Ignore the label.
Just watch how the person moves.
If the numbers look better but the movement hasn't changed, you haven't fixed anything. You've just found a way to measure around the problem.
And if your model depends on numbers improving to prove you're right, you're not assessing.
You're performing.
