Try gripping a soft ball or other object as hard as you can. Change your wrist position as indicated in the trials
Trial 1
Neutral Wrist
Trial 2
Wrist Flexion
Trial 3
Wrist Extension
Can you see that the ball in this example compresses the most in neutral?
Did you discover in your own Trial 1 that neutral is your strongest position?
Was it easiest to squeeze the ball in neutral, and harder in flexion and extension?
Now you’ve directly experienced the effect your wrist position has on your grip strength!
