An electrically-powered, body-weight unloading, gait rehabilitation device designed to assist a patient with a walking/balance disability (neurogenic, muscular, or osseous in origin) regain lost motor function, by enabling them to hang in a dedicated harness in a vertical position and exercise (e.g., walk over the ground or moving surface of an elliptical/treadmill, climb stairs, perform sit-to-stand movements). It consists of a ceiling- or wall-mounted beam, or floor-standing frame with a motorized attachment assembly connected to the harness which supports the body weight. It is intended to be used in a clinical setting under professional supervision.
