Abstract

A description is given of the control of standing-up movement from a wheelchair and locomotion for paraplegics by functional electrical stimulation (FES). In order to determine stimulation patterns of lower extremity muscles, activities of 21 muscles were analyzed in normal subjects by averaging their EMGs (electromyograms). On the basis of this analysis, standard stimulation patterns for the lower extremity muscles were programmed and stored in a 64-channel portable FES system. The standing-up movement induced by FES was easily achieved after several exercises, and the standing position could be kept very stable. Using hand switches attached to a walker, the patient was able to control locomotion
