Body weight supported treadmill training (BWSTT) has been confirmed to be an effective gait rehabilitation therapy for patients with locomotor dysfunction of the lower limbs. Powered Gait Orthosis (PGO) is a pair of powered mechanical legs in exoskeleton structure, which can guide the patient’s legs to move in a preprogrammed physiological gait pattern during BWSTT. A prototype of single-leg PGO has been designed and constructed. It has linear actuators at hip and knee joints; it is also instrumented with sensors and encoders. To realize the physiological gait movement of the single-leg PGO, a control platform, a safe protection device, and a set-point gait motion control method have been developed. The effectiveness of the proposed set-point gait motion control method is confirmed by the preliminary experimental results..
