ABSTRACT:
A hip reciprocating apparatus of a reciprocating gait brace provides for transfer of forces from movement of one leg to a reverse movement of the other leg of a user. A C-shaped pivot member pivots about a horizontal axis and is mounted at the back of the pelvic band of a gait brace. The pivot member ends are adjacent hip joints which couple the pelvic band to a leg or lower hip joint member. A length-adjustable tie rod couples the pivot member ends to posteriorly extending protrusions of the associated leg member. The pivot point of the pivot member may be equally or unequally spaced relative to the pivot member ends. The leg member protrusions may be of different lengths. A spring may be used to store energy during pivoting of the pivot member in one direction and release of the energy during pivoting in the other direction. An external power source may apply energy to movement of the pivot member in both directions.
