Reciprocating Gait Orthosis [RGO]
RGO is a lightweight bracing system that gives structural stance phase support to the lower trunk and lower limbs of the patient with lower extremity paralysis. It uses a cable-coupling system to provide hip joint motion for the swing phase. In the RGO, via its cable system, flexion of one hip (in swing) results in extension of the other hip (concurrently in stance). The hip joints of the orthosis are coupled together using two Bowden cables to transmit the necessary forces (although the original design used a single cable, functional problems and subsequent revisions evolved into the use of a second cable). This reciprocal coupling has the added benefit of eliminating simultaneous hip flexion and reducing the risk of “jack knifing” during ambulation.
RGO prescribed for Children with myelomeningocele who had absence or weakness of the hip extensor mechanism, Adults and children with paraplegia and Children with the thoracic and high lumbar level of paralysis.
