要約(日本語): Innervation Zone (IZ) location shifts according to change in muscle length, and it’s impossible to evaluate muscle contraction around IZ. This study proposed a new evaluation method for muscle function while avoiding IZ automatically, and evaluated muscular fatigue during dynamic contraction using electrode array. In the method, the characteristic waves were extracted, and IZ location was estimated using cross-correlation and amplitude ratio between a neighboring channel. The muscular fatigue was evaluated from muscle fiber conduction velocity (MFCV) using channels without IZ location. As the result, MFCV value decreased with muscular fatigue and the characteristic agree with conventional. Thus, it is possible to evaluate muscle function with changing muscle length using the system.
