보향각도 변화에 따른 발목관절 모멘트의 분석

초록

The purpose of this study was to investigate the differences and changes of moment influenced by the change of toe out angle(TOA). The 9 healthy female volunteers participated in the study(mean age 25±2 years, mean heights 166±1.27cm, body weights 54kg). The body weights and shoes influenced on the moment. There for the all subject have same body weights at 54kg, and when they are walked without shoes on a ground reaction force plates(GRFP) for along 15m. And that moment were measured and analyzed. Which are three groups( group A is the 15° in TOA, B is 20° in TOA, C is 25° in TOA). It were on the based in normal gait straight and gait speed walked on GRFP. The moment were measured antero-posterior, medio-lateral, vertical moment in each groups. The data analyzed by One way repeated AVONA and Duncan. The results were as fallows; 1. The plantar-dorsiflexion moment increased at the group A than group B. Therefore, normal gait has more ankle stability and plantar-dorsiflexor muscle activity. 2. The abduction-adduction moment increased at the group C than group A, B. The group C has danger of the ankle injury because lack of the medial-lateral stability. 3 The inversion-eversion moment increased at the group C than group B than group A.
