Upper extremity muscle therapy system

An apparatus, for treating diminished muscle function in an upper extremity, comprising:

• an electrical member that delivers electrical energy to a hand region comprising at least one of a digit, a hand, and a wrist, the hand region comprising a dysfunctional muscle;
• a hand joint motion assembly that couples to the hand region and provides a joint motion, in a cycle comprising opposing joint movements, to a joint to which the dysfunctional muscle ordinarily provides motion;
• and
• that controls (i) a timing of electrical energy delivery by the member and (ii) an amount of electrical energy delivered by the member;
• wherein the timing of electrical energy delivery is controlled to occur while both of the following occur simultaneously:
• (i) the joint is near an inflection point between opposing joint movements in the cycle, and (ii) motion is being provided to the joint by the joint motion assembly;
• and
• wherein the amount of electrical energy delivered is effective to result in a depolarization of at least one of the dysfunctional muscle and a nerve that innervates the dysfunctional muscle.
