Parkinson’s wants to create small cupped hands and flexed fingers. Work on activating the extensors and practice BIG HAND exercises to counteract the flexed posturing of the hands. PWR! Hands can be used as a warmup to gain control of a tremor and to increase challenge and attentional awareness to your PWR!Moves exercises. Steve Miller, one of our PWR! trained Instructors, developed this fun hand dance routine.
