1. An FES method for partially restoring the motor function of a person having paralyzed muscles, said method comprising:

  • implanted a force sensor comprising a nerve electrode for sensing electrical signals primarily from mechanoreceptors associated with a peripheral sensory nerve that supplies glabrous skin of the person having the paralyzed muscles,sensing electrical signals via said force sensor,producing an electrical control signal for activating a muscle stimulator in response to the electrical signals sensed by said nerve electrode, andstimulating the paralyzed muscles in accordance with said control signal.
