Some embodiments of the present invention provide systems and methods for treating diminished muscle function. Some systems include an electrical member that delivers electrical energy to a hand region of a body that comprises a dysfunctional muscle a joint motion assembly that couples to the body and provides, to a joint adjacent the dysfunctional muscle, a motion made up of a cycle of opposing joint movements and a control unit that provides an operator of the system with control of a timing of electrical energy delivery and an amount of electrical energy delivered. Some systems time the electrical energy delivery to occur when the moving joint is near an inflection point and deliver electrical energy delivered in amounts effective to result in a depolarization of the dysfunctional muscle, a nerve in proximity of the joint, and/or a muscle of substantially normal function in proximity of the joint.
