Examination of exercise evaluation by conduction wave analysis using multi-channel surface EMG

Abstract

Elucidation of muscle activity is important in clinical fields such as diagnosis of sarcopenia.Muscular activity is regulated by types and number of motor units(MU). The action potential generated by MUs are measured as electromyography(EMG).The multi-channel surface EMG(sEMG) is used to analyze the conduction of muscle potential. It is recorded as the interference electric potential generated by MUs. In previous study, we proposed a method for searching all conducting waves appearing quantitatively in the multi-channel sEMG by calculating the similarity of the waveforms. It has possibility to estimate the mobilization of MUs by examining conduction waves. In this study, we investigated the feasibility of the motion analysis using conduction waves by examining the relationship between the acquired conduction waves and the sEMG with different muscle states and motion conditions using this method.By analyzing conduction waves, we could confirm the change of sEMG due to the movement state.
