Abstract :
The purpose of this study is to construct “FES simulator” which is a simulation system of restoring paralyzed motor functions with FES. The simulator enables to modify stimulation data through the estimation of motion by the data before applying the stimulation to a patient. In this paper, a practical model of electrically stimulated muscle was studied for FES simulator. Stimulus frequency-force characteristics obtained in our past work were used for describing the model with tractable parameters and for controlling the model by stimulus frequency with amplitude and/or width of a pulse. The description was useful to represent different properties between electrically stimulated fast and slow type muscles
