Abstract
Abstract The exercise apparatus, in the embodiment shown, is adapted for replaceable attachment to the wheelchair of a handicapped user. It encompasses a support frame, gear motors and rotating discs with connecting rods that cause the wheelchair and the apparatus's handles and foot supports to move back and forth. This action enables a user, who is unable to move on his or her own, to experience a range of motion that provides exercise for the muscles in the torso and the extremities.
