Abstract: The electrical stimulation device includes: positive and negative electrodes to be attached to epidermis of agonist-antagonist muscles acting on a target joint; a display unit; an EMG rehabilitation unit that detects an electromyogram of the agonist-antagonist muscles via the electrodes and outputs variation information corresponding to the detected electromyogram to the display unit; a FES rehabilitation unit that instructs motion of the agonist-antagonist muscles via the display unit and outputs a stimulation current signal corresponding to the instructed motion of the agonist-antagonist muscles to the electrodes; a model (inverse model) storage unit that stores models obtained beforehand and relating to target muscle characteristics, the models including: a model for converting the detected electromyogram into the variation information; and a model for converting information on the motion of the agonist-antagonist muscles into the stimulation current signal; and a rehabilitation processing unit that selectively executes the EMG rehabilitation unit and the FES rehabilitation unit.
