Give our pen-grasping experiment a try!
Hold the pen as tightly as you can in each of the wrist positions indicated in the trials. Have a partner try to pull the pen out of your grasp . . .
Did you discover in Trial 1 that neutral is your strongest position?
Was it harder to hold onto the pen in trials 1 & 2 in wrist flexion and extension?
Now you’ve directly experienced the effect your wrist position has on your grip strength!
