What Your Hands Can Tell You About Coordination
A Simple Assessment
There’s a test I come back to regularly—not just with dancers, but on myself.It’s quick.
It’s simple.
And it gives me a surprising amount of information.Especially on days when things feel a little “off.”
First—What Is the Cerebellum?
In very simple terms:The cerebellum is the part of your brain that helps coordinate movementIt helps with:
Timing
Rhythm
Accuracy
Smoothness
It doesn’t create movement.
👉 It refines movement. So instead of:
stiff
jerky
inconsistent
You get:
smooth
controlled
efficient
The Test: Rapid Alternating Hands
Try this:
Hold one hand out in front of you
Quickly alternate:
Palm up → palm down → palm up → palm down
Go as fast as you can while staying controlled. Then switch sides.
Here's a clip demonstrating the assessment. My left side was not quite as 'crisp' as my right side.
What You Might Notice
Don’t overthink it—just observe.
One side may feel:
The other side may feel:
slightly clumsy
harder to control
like it “falls apart” when you speed up
👉 That difference is meaningful.
A Key Insight (This Is Important)
Each side of your cerebellum helps coordinate movement on the same side of your body.So if your right hand feels less coordinated…
👉 That may reflect how your brain is organizing movement on your right side
Why I Personally Pay Attention to This
I’ve noticed a few things over time:
If I’m fatigued, this test changes
If I haven’t been doing my eye work consistently, this test changes
Some days, one side just feels less “clear”
That doesn’t mean something is wrong.
👉 It means my system isn’t as reliable or efficient in that moment.And that often shows up in movement too.
For You as a Teacher
Before you ever use this with students:
👉 Use it on yourself.
Notice:
Does one side consistently feel different?
Does it change day to day?
Does fatigue influence it?
Because once you feel it in your own body…👉 You’ll recognize it instantly in your dancers.
Important Reframe
This is not about:
Good side vs bad side
Strong vs weak
Instead think:
👉 Clear vs unclear
👉 Reliable vs less reliable
That language matters—especially when you start using this in class.
To your success,
