A performance evaluation apparatus and performance evaluation method capable of efficiently evaluating the performance of a wearable motion assistance device is provided, which assists motions of a wearer's lower back part. In a state where the wearable motion assistance device is secured and mounted on both femur links and a trunk link, torque acting on an axis line of a pitch direction relative to the trunk link for each hip joint is detected while controlling driving forces by first and second driving sources so that a posture of the trunk link and rotation angles of each hip joint and each knee joint virtually match motions of the lower back part of the wearer; and performance of an assist force by the wearable motion assistance device is evaluated based on a detection result of the torque according to drive control of the first and second driving sources.

A gait orthotic device, such as a powered exoskeleton, includes at least one joint; at least one actuator configured to cause movement of the device at the joint; a cushioning mechanism coupled to the device for absorbing energy or spreading a force during an impact with a surface or object; and a controller. The controller is configured to determine when a fall is occurring and direct the actuator to: orient the device so the cushioning mechanism makes contact with the surface or object during the fall; or reduce a kinetic energy of the device during the fall by performing positive joint work. The cushioning mechanism can take various forms, including an airbag, a spring, a bumper, a roll bar or a kickstand. Preferably, the cushioning mechanism is an airbag in the form of an airbag module that is detachably coupled to the device for removal and replacement.
