Prosthesis or prosthetic amputation is the method of replacing a body part with an artificial part. A Prosthetic hand is an artificial device which replaces the missing hand of an amputee. The artificial device could be either non-moving aesthetic arm or an automated motor controlled movable arm. The automated movement is controlled by various methods which are discussed in this paper. Control methods of EMG and EEG are discussed here. Electromyography (EMG) is a technique for evaluating and recording the electrical activity produced by skeletal muscles. It is recorded using a device called Electromyogram which detects the electric potential generated by muscle cells when they are electrically or neurologically activated. Electroencephalography (EEG) is a method to record electrical activity of the brain, using electrodes placed along the scalp. EEG measures voltage fluctuations resulting from ionic current within the neurons of the brain. This paper compares these
