GRIP STRENGTH OR GRIP COORDINATION? 🎾
Alan has a confirmed shoulder labral tear.
He’s playing tennis hard, playing frequently, and experiencing NO SHOULDER PAIN.
But we’re still working.
Why?
Because our goal isn’t simply to eliminate pain.
It’s to continue developing his muscular capacity while managing the demands placed on his shoulder.
And now we’re back to his fingers.
Here’s what we found.
LEFT INDEX FINGER EXTENSION: HIGH QUALITY.
Now introduce thumb flexion while maintaining that index-finger extension.
THE QUALITY DETERIORATES.
Wait a minute.
The index finger works independently.
But when the thumb gets involved, the coordinated response changes?
And then Alan tells me something interesting.
“That’s part of how I grip my tennis racket.”
Now we have a specific relationship worth investigating.
Because grip strength and grip coordination aren’t necessarily the same thing.
You might be able to produce plenty of force with individual fingers.
But can you maintain that force when multiple fingers must work together?
What happens when you add the wrist?
The forearm?
The shoulder?
Resistance?
Fatigue?
That’s where the demands become much more complex.
We’re not simply strengthening his hand.
We’re developing his ability to coordinate specific finger configurations and investigating how that capacity responds as the demands change.
And remember, he still has a torn labrum.
So every progression requires appropriate loading, monitoring, and retesting.
We’re not claiming his grip caused the shoulder injury.
We’re identifying another area of his muscle system where we can improve the quality of coordinated force production.
One configuration. One adjustment. One validated response at a time.
Because Alan doesn’t play tennis with one finger.
He plays with an entire system that must work together.
The exercise isn’t the point. The decision behind the exercise is.
Assess → Manipulate → Retest → Validate → Adjust.
