高周波筋音による筋肉の評価

In this research, we focused on mechanomyogram (MMG) to evaluate muscle activities. In previous researches, low frequency MMG ranged 10 to 100 Hz were mainly measured. On the other hands, we focused on MMG ranged higher than 100 Hz which is considered to be related to the resonance of muscle fibers. To measure high frequency components of MMG, we use wideband acoustic emission sensor and measured the MMG of the biceps brachii muscle of multiple subjects. As a result, it was confirmed that each subject included the frequency components of 100 Hz to 10 kHz in the MMG. In particular, it was found that as the force exerted by the muscles becomes larger, the MMG of 1 kHz to 10 kHz becomes larger.
