Upper and lower body exerciser that can be used by people with lower body paralysis

摘要

An exercise device for people with lower body paralysis. The exercise device guides and resists the motion of the hands and feet away from and towards the trunk. The exercise device holds the feet at a nearly constant angle in relation to a line drawn between the ankles and hips. The arm motion is constantly mechanically linked to the leg motion so that voluntary arm motion causes motion of paralyzed legs. A knee guide keeps paralyzed legs in proper alignment. Arm motion controls the application of electrical stimulation to leg muscles. Electrical stimulation of leg muscles causes the generation of leg forces that contribute to the overcoming of the resistance to the movement of the hands and feet in relation to the trunk.
