Sit-to-stand assist system by using handrail and electric bed moving up and down

In this paper, we propose a user adaptive support system for sit-to-stand movement from a bed. The support system consists of a handrail and an electric bed which moves up and down. The evaluation indexes for the sit-to-stand movement based on a human model are introduced. By using these indexes, we set the parameters of the support system such as the handrail position, the height of the bed, and the foot position, for stabilizing the userpsilas posture and reducing the burdens of the userpsilas muscles. The parameters of the support system are determined according to the body size and the disability of the user, and the experimental results illustrate the validity of the method for setting the handrail position, the height of the bed, and the foot position.
