A Study for Conducting Waves by Using the Multi-channel Surface EMG

摘要

The surface electromyogram (EMG) is recorded as the interference electric potential generated by motor units in muscle. Therefore, it may be possible to analyze the muscle contraction mechanism in order to examine the composition of the interference signal of the surface EMG. We herein propose a new method by which to analyze the composition of the surface EMG. The proposed method involves searching conducting wave which mean similar waveforms considered same wave appearing during several channels by using multi-channel surface EMG, and we can analyze surface EMG as a set of conducting waves. The proposed method is referred to as the multi-channel method for conducting waves (m-ch method). We analyzed multi-channel EMG using the proposed method.
