| Research Abstract |
The purpose of this study was to develop the method for simulation by which the anatomical and physiological characteristics and the state of the active motor units were clarified from surface EMG. Models of the simulation include some parameters which were the distribution of motor units(MUs) and muscle fibers on the cross section, the muscle fiber conduction velocity, the threshold of recruitment of MUs, the twitch strength of muscle fibers etc. The following studies were executed with models mentioned above : (1) reconstruction of activities of motor units during rapid contraction, (2) examination of relationships between muscle type and surface EMG, (3) visualization of activities of MUs with inverse analysis, (4) examination of the validity of the models by finite element method.
