A myoelectric prosthesis controller

Myoelectric prostheses are preferred for their natural way of control and enhanced cosmetic restoration. Developing a software program that proportionally controls an upper limb myoelectric prosthesis is our target. Software processing of the (EMG) signal was performed by extracting the energy, RMS, and zero crossings features from the EMG signal, and then generating the appropriate control signal to the prosthesis for the required movements. A study for the amputee´s muscles was performed to choose the suitable muscles for the prosthesis operation. Results had shown that the introduced control on/off performance was over 95% and its proportional performance was over 80 %.
