It can automatically record the users’ rehabilitation information timely when users’ do the rehabilitation exercise. After finish rehabilitation exercise, users use human-machine interface upload the information to computer and create files. The files provide users for self-examination, and help the doctors to analyze the development of rehabilitation treatment. This work uses LED status light to indicate current scale of strength being exerted, and record the users' LED status. The users view about their charts and tables of rehabilitation information as well as calories consumed after rehabilitation exercise. The micro processor has power-saving model, so it won’t consume too much power when idle.
