A computer-controlled functional electrical stimulation (FES) system has been developed to provide severely disabled quadriplegics with the ability to control their paralyzed hand. In order to increase the security of electrically induced hand movement, electromyography of hand muscles during movement was analyzed in normal subjects. It was found that not only prime movers but also agonists and antagonists played an important role in the performance of hand movement. Application of this analysis to FES of the paralyzed hand resulted in graded movement and stable positioning of the fingers. On the basis of these data, a sequence of multichannel stimulation for restoring prehension and release was introduced to a voice-controlled FES computer system.
