<P>PROBLEM TO BE SOLVED: To provide a functional electric stimulation system enabling a user to more naturally walk. <P>SOLUTION: The functional electric stimulation system for walk assistance includes: a drive force imparting device for imparting a drive force to a foot joint by individually electrically stimulating each of a plurality of muscles around of the foot joint; stimulation electrode supporters 1, 5 to be attached to the lower extremity to give electric stimulus; sensors 3, 4 for detecting that the legs contact the ground; and sensors 7, 8, 12, 13 for detecting the angle of foot joints respectively. The system estimates muscular output online on the basis of a skeleton model of a passive walk mode and a muscle skeleton mathematical model, converts the estimated output into a stimulus pattern corresponding to each of the muscles, and causes the stimulation electrode supporters to individually electrically stimulate each of the muscles based on a stimulus pattern corresponding to each of the muscles. <P>COPYRIGHT: (C)2013,JPO&INPIT |
