THE INFLUENCE OF WALKING SPEED ON SYMMETRY FOR TEMPORAL-SPATIAL AND GRF PARAMETERS IN BACKWARD WALKING

摘要

In general, changes in walking speed are known to influence many biomechanical characteristics of human locomotion. Backward walking (BW) is one of the unique strategies of human locomotion, but there is a little information in BW. The purpose of this study was to investigate whether or not walking speed influences on symmetry for temporal-spatial parameters and GRF in BW. Ten healthy subjects were asked to walk on a walk-way with force platform at three times on three speed conditions. The influence of walking speed on temporal-spatial parameters and GRF parameters were founded, and some gait parameters showed asymmetry. And also the calculated SI were showing asymmetry, so the characteristics of backward walking would be influenced walking speed and have possibility of exist some asymmetrical movements in lower leg.
