The Science behind Handmaster Plus

Finger extensor muscles, located generally on the back of the hand, wrist & elbow, contract aggressively to support any gripping action. Because little attention has historically been placed on this stabilizing role, imbalance, performance limitation and injury have been rampant in sports, music and the workplace.

Traditional hand therapy applications included a ‘rice box’ application, whereby the patients immersed his or her hand in the rice and opened and closed it naturally against the resistance of the rice. Limitations to the exercise (and inconvenience) rendered the exercise nearly extinct. Handmaster Plus is a great evolvement of the basic rice box idea of natural resistance.

Handmaster Plus strengthens all 9 finger extensor muscles AS WELL AS all 9 finger flexor muscles through full, natural, 3-dimensional ranges of motion.
