Gait total lower-limb functional orthoses propelled by the user\'s muscular power that are designed to make possible and/or improve a patient\'s gait. These devices provide support, supplement, and/or augment the limb functions through a linkage between both legs that permits 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 system to couple the leg extension and flexion; additional crutches are frequently needed to provide balance to the user.
