초록

The purpose of this study was to investigate the different patterns of the lower limb between elderly and adult females to reduce the rate of falls. Ten old females(age: $73.1{\pm}2.69yrs$, height: $151.9{\pm}4.82cm$, mass: $57.36{\pm}5.36$) and ten adult females(age: $28\pm}4.76$ yrs, height: $160.6{\pm}6.83cm$, mass: $53.9{\pm}8.44$) were participated in this experiment. The gait motions were captured with Qualisys system and variables were calculated with Visual-3D. The following results were found. The elderly female group showed bigger inclination angle between COM and COP than the adult female group so that the dynamic stability was reduced in walking for the compensation with a bigger stride width. The elderly female group ensure for the necessary forward movement of COM in order to replace the decreased function of ankle and knee joint. If the distance between COM and COP is closer and the energy reduction of a specific joint is reduced, they could prevent the elderly female's falling rate by strengthening of muscles which were related the extension of ankle joint.
