Abstract

The purpose of this study is to convergence comparison the ankle joint angle change during walking of college students in their 20s with flat foot according to the heel height of insole shoes. Qualisys Track Manager Software ver. 2.8 (Qalisys Track Manager) was used for 15 college students. Functional shoes with insoles were manufactured, and the heel heights of the shoes were set to 3cm and 7cm. The subjects wore shoes with two high heels and gaited by attaching a reflex marker to the side of the ankle joint. The angle change of the ankle joint was measured in the gait stance phase. The angle of the ankle joint significantly decreased both heel strike, foot flat, midstance, and toe off to the heel height increased when the subjects with flat feet wore insole shoes. Therefore, it is thought that flat feet should wear low shoes when wearing insoles to reduce the fatigue of the soles and to walk comfortably.

본 연구의 목적은 인솔구두의 굽 높이에 따른 평발을 가진 20대 대학생의 보행 시 발목관절의 각도변화에 대해 융복합적 비교를 하는 것이다. 15명의 대학생을 대상으로 동작분석기(Qualisys Track Manager)를 이용하였다. 인솔이 장착된 기능성 구두를 제작하고, 구두의 굽 높이를 0cm, 3cm와 7cm로 셋팅하였다. 실험대상자들은 두 개의 굽 높이가 있는 구두를 신고 발목관절의 측면에 반사마커를 부착하여 보행을 실시하였다. 보행입각기에서 발목관절의 각도변화를 측정하였다. 평발을 가진 실험대상자가 인솔구두를 착용 시 구두 굽 높이가 높을수록 양측의 Heel strike, Foot flat, Midstance, Toe off에서 유의한 감소가 나타났다. 따라서 평발을 가진 대상자는 인솔구두를 착용 시 낮은 구두를 신어야만 발바닥의 피로를 감소시켜 편안한 보행을 할 것으로 사료된다.
