Reconstruction of paraplegic standing and walking with medial hip joint system

Abstract

For reconstruction of paraplegic standing and walking, we developed a medial single hip joint system (MSH) which have a virtual axis with sliding arc guide. We compared this system with original MSH in some paraplegic patients. In result, our system was excellent in gait velocity, cadence and stride. To reduce the fatigue of upper extremities during walking with two crutches, we tried to provide the motor system for the MSH. But, the operation of finger switches was very complexly. We think there are two points of view to be the MSH system of practical use; the convenience in daily life and the joint use with wheel chair.
