젊은 성인 여성의 구두 힐 높이 별 보행특성 및 하지관절 간 상호작용 비교분석 = Analysis of the Gait Characteristics and Interaction among Bilateral Lower Extremity Joints According to Shoe`S Heel Heights in Young Women

다국어 초록 (Multilingual Abstract)

The purpose of this study was to analyze the gait characteristics and interaction between lower extremity joints according to shoe`s heel heights in young women. Participants were selected as subject consisted of young and healthy women (age: 23.71±1.49 yrs, height: 165.92±2.00 cm, body weight: 54.37±3.46 kg) and walked with 3 types of shoe`s high-heel (0, 5, 9 cm). The variables analyzed consisted of the displacement of Y axis in center of mass ([COM]; (position, velocity), front?rear(FR) and left?right(LR) angle of trunk, lower extremity joint angle (hip, knee, ankle) and asymmetric index (AI%). The displacement of Y axis in COM position showed the greater movement according to increase of shoe`s heel heights, but velocity of COM showed the decrease according to increase of shoe`s heel heights during gait. The hip and knee angle didn`t show significant difference statistically according to increase of shoe`s heel height, but left hip and knee showed more extended posture than those of right hip and knee angle. Also ankle angle didn`t show significant difference statistically, but 9 cm heel showed more plantarflexion than those of 5 cm and 0 cm. The asymmetric index (AI%) showed more asymmetric 9 cm heel than those of 0 cm and 5 cm. The FR and LR angle in trunk tilting didn`t show significant difference statistically according to the increase of shoe`s heel height during gait in young women.
