抄録

In recent years, aging of population is more and more progressing. The number of people who is bedridden is increasing because muscle strength and muscle mass decrease as people age. Therefore, rehabilitation and training are needed for independent lives. In order to improve their safety and efficiency, it is important to measure the state of muscle activity and muscle fatigue. Mechanomyogram (MMG) is one of the invasive method to evaluate a state of muscle. In addition, measuring surrounding muscles simultaneously is necessary to evaluate effects of rehabilitation and training because motions are performed by some muscles. Therefore, in this study, the state of crural muscles in isometric contraction was measured by multipoint MMG. Four sensors were taped on medial head of gastrocnemius muscle, lateral head of gastrocnemius muscle, tibialis anterior and the shinbone. Root mean squares and power spectral densities (PSD) were calculated from MMG signal to measure muscle activity. By comparing PSDs from four sensors, there are different frequency components in PSD from medial head from that from lateral head. From the results, it was found that the multiple MMG measurement is available to estimate the whole muscle activity during exercise.
