Abstract

In order to estimate the analog pattern of the motor commands which control the degree of contraction of a muscle as a whole, computer programmed pulse density demodulation (PDD) processing for surface electrode electromyograms (EMG) of human extremities has been developed. The principle of the pulse density demodulation processing of electromyograms (PDD-EMG), alignment of the multichannel surface electrodes, setting of the optimal threshold for pulse extraction, and elimination of the influence of secondary pulses are discussed in this report
