Self-propelled gait total lower-limb functional orthoses propelled by muscular power that are designed to make possible and/or improve gaiting by augmenting the limb functions through a linkage between both legs that permit simultaneous extension of one hip and flexion of the contralateral hip. These orthoses include a mechanism that provides the appropriate linkage between the legs for step-over-step gait (known as reciprocating gait orthoses, [RGO]). The mechanism usually includes a cable and pulley system to couple the leg extension and flexion; crutches are frequently needed to provide balance. Also available are dedicated RGOs that use a frame resembling a walker and a pivoted central bar instead of cables. These facilitate the reciprocating gait capability with less effort. Known as isocentric reciprocating gait orthoses (IRGO), these orthoses are frequently used by children.
