Abstract

The purpose of this study was to investigate the effect of visual information on the dynamic balance on Y-balance Test(YBT). The subjects of the study were 18 male and female adults in their 20s and 30s (age: 23.17±1.72 years, height: 172.46±9.84 cm, weight: 73.39±11.44 kg, leg length: 88.89±5.69 cm) who participated in the study. To measure dynamic balance between binocular and monocular use, absolute reach distance, composite score, and COP variables were measured on left and right feet through YBT and results were derived. As a result of the study, monocular block(left and right eye block) showed higher absolute reach and composite scores than binocular use in posterolateral, posteromedial, and composite scores during YBT. As a result of COP, there was no difference in anterior and posteromedial reach. When reaching posterolateral, AP COP velocity of left foot in monocular block appeared slower than that in binocular vision, and in COP velocity, COP velocity of left foot in monocular block appeared slower than binocular vision.

본 연구의 목적은 시각정보로 양안시와 단안시 사용 시 Y-Balance Test(YBT) 수행이 YBT 절대도달거리, 수행점수와 압력중심 변인을 통하여 동적균형에 미치는 영향을 알아보고자 하였다. 연구의 대상자로 20-30대 성인 18명(연령: 23.17±1.72 년, 신장: 172.46±9.84 cm, 체중: 73.39±11.44 kg 다리길이: 88.89±5.69 cm)이 연구에 참여하였다. 양안 및 단안 사용으로 동적 균형 측정을 위하여 YBT를 통하여 절대도달거리, 종합점수, COP 변인들을 좌우발에서 측정하여 결과를 도출하였다. 연구결과로 YBT 시 후외측, 후내측, 종합점수에서 단안 차단(좌우 눈 차단)이 양안 사용보다 절대도달거리 및 종합점수가 높게 나타났다. COP 결과로, 전방 및 후내측 도달 시 차이가 나타나지 않았지만, 후외측 도달 시 전후 COP 속도에서 왼발은 단안 차단이 양안시 보다 전후 COP 속도가 느리게 나타났고, COP 속도에서 왼발은 단안 차단이 양안시 보다 COP 속도가 느리게 나타났다.
