EMG controlled prosthetic limbs, as the name suggests, are artificial limbs controlled by EMG signals which replace an amputee's limb. Since the muscles in the remaining part of the arm function in a normal way, this enables the EMG signals to be used to control the prosthetic device. Therefore, a signal obtained from the patient's body controls the input to drive motors coupled to the prosthetic limb. Bitzer et al. successfully demonstrated EMG-based control of a four-finger hand which can be used to grasp objects. Graupe et al. in described a prosthesis control system where control of an artificial limb for above-elbow amputees was achieved. The design involves time series identification techniques for parameter discrimination. Okuno et al.
