This study focuses on an at-home wrist rehabilitation system aimed at achieving a situation where a home-stay patient can receive rehabilitation from a therapist in a clinic. In a former report, a pneumatic driven at-home wrist rehabilitation system, which could be used for passive exercise, was developed. Using the same system that was developed, this paper discusses the realization of rehabilitation by active exercise based on the wrist characteristics obtained in passive exercise. Firstly, game-based active-resistive exercise is proposed. Then game-based active assistive exercise using the wrist characteristics obtained in passive exercise to set up the assist torque is proposed. From the experimental results in the clinic, the validity of rehabilitation by active exercises developed in this paper is verified. From the above, it is clarified that both passive and active exercise could be carried on by the at-home wrist rehabilitation system developed in this research.
