[The study advances and prospects of processing surface EMG signal in prosthesis control]

The surface EMG signal has direct relations with extremity movements and has become the ideal control signal for man-machine bionic system. This paper discusses the analytic study of surface EMG signals and gives various character estimations. Two kinds of character recognition methods of surface EMG are introduced for controlling prosthesis movements. The existing problems of multi-function EMG prosthesis control are summed up. In the end prospects for the study on analytic ways of surface EMG signal and the practical applications are discussed too.
