초록
본 연구의 목적은 안정한 지지면, 불안정한 지지면에서 시각 조건이 균형에 미치는 영향에 대해 알아보고자 하였다. 건강한 성인 30명이 본 연구에 참여하였다. 시각 조건은 수직, 수평, 대각선으로 설정하였고 불안정한 지지면에서의 균형 측정을 위해 패드를 밟고 측정을 수행하였다. 균형측정기를 통해 안정성 지수(General Stability Index)와 체중 분포 지수(Weight Distribution Index), 체중 분포도(Weight Distribution)를 측정하였다. 지면 간 비교는 대응 표본 t검정을 하였고, 지면 내 비교는 일원배치분산분석을 사용하였다. 불안정한 지지면에서 시각 조건 내 (수평, 수직)의 안정성지수는 유의한 차이를 보였고(p<.05), 지면간의 비교에서 체중분포지수에서 유의한 차이가 있었다(p<.05). 체중분포도는 수평 방향의 시각의 모든 지지면에서 왼쪽과 오른쪽 사이의 유의한 차이가 나타났다(p<.05). 정적 균형 훈련 시, 수평보다 수직과 대각선의 시각 조건을 준다면 균형 훈련에 도움을 줄 수 있다고 사료된다.
Abstract
The purpose of this study was to investigate the effect of visual conditions on the static balance of stable and unstable surfaces. Thirty healthy adults participated in this study (13 men, 17 women). Visual conditions were set as vertical, horizontal, and diagonal. It was performed on the pad to measure the balance on the unstable support surface. Using the balance measuring instrument, the General Stability Index, Weight Distribution Index, and Weight Distribution was measured. Paired t-tests were used for ground-based comparisons and one-way ANOVAs were used for comparisons within the same ground. The general stability index showed a significant difference according to the horizontal and vertical line directions on the stable support surface(p<.05). According to the comparison between the grounds, the weight distribution index on the unstable support surface showed a significant difference(p<.05). Weight distribution showed significant differences between the left and right eyes on the support surface with the stable and the unstable horizontal visual condition(p<.05). In static balance training, vertical and diagonal visual direction conditions are predicted to be helpful for training.
