Walker Gait Analysis of Powered Gait Orthosis for Paraplegic

At KOREC, first of all, a prototype of a powered gait orthosis(PGO) has been developed to reduce the energy consumption and the muscle fatigue. Each hip joint of the PGO is flexed by an air muscle operated by pressurized air enabling the patient to walk. In this study, we compared gait characteristic of powered gait orthosis in parallel bar and walker about 3 paraplegic patients. As results, hip jont and pelvic angle is similar angle about RGO and PGO in parallel bar gait and walker gait. But gait speed and gait cycle parameter is decrease more than RGO gait. It will can improve by gait training about balance and speed.
