Influence of body weight and prosthetic flexible ankle on walking balance parameters in transtibial amputee gait

Abstract

The walking balance of transtibial person has been widely documented in many literature. However, the effect of walking balance of transtibial amputee between body weight and a prosthetic foot is not widely known. This study was used for gait analysis to measure the walking equilibrium parameters amputated from 14 people with transtibial. To reduce variability among subjects at the time of testing, we carried out washing out for all subjects for 2 days. Data generated that all subjects walked in one direction straight to measure the walking balance and kinetic parameters. Design experiment with a crossover design, subjects with amputations walked for a distance of 80 meters, estimated time of 6 minutes and speeds about 1.20 to 0.15 m per sec, during the gait phase. The movement of the ankle in the plantar flexion position is reduced because in the final phase, the standing ankle becomes flexible. Correlation analysis shows that the effect of walking balance when wearing a prosthetic foot is measured during 1 gait cycle. The results depend on the design of prosthetic foot and how to walk.
