COP 95% Confidence Ellipse Area를 이용한 외발서기 균형 평가

  • Published : 2008.06.30

Abstract

The purpose of this study was to investigate of assessment of the ability of balance control using COP 95% confidence ellipse area while executing single-leg stance with eyes open and eyes closed through GRF system. The subjects participated in this study were 7 female yoga group and 7 female control group. The yoga training affected to improve the ability of balance control because the yoga group's COP AP and ML standard deviation and COP 95% confidence ellipse area were smaller than control group in both a single-leg stance with eyes open and eyes closed. Visual affected to the ability of balance control in a single-leg stance. I consider COP 95% confidence ellipse area as a high variable for determining the ability of balance control, and therefore suggest that additional studies for various groups and subjects will be required in the future.

이 연구는 요가 수련 그룹 7명과 비수련 그룹 7명을 대상으로 눈뜨고 눈감고 외발서기 시 COP 95% confidence ellipse area를 이용하여 균형 제어 능력을 평가하는데 그 목적이 있다. 요가 수련 그룹이 눈뜨고 눈감고 외발서기 모두에서 COP 전후 좌우 표준편차와 COP 95% confidence ellipse area가 비수련 그룹보다 유의하게 작게 나타나 요가 수련이 균형 제어 능력 개선에 영향을 미치는 것으로 나타났다. 요가 수련 그룹 내에서는 COP 전후 좌우 표준편차와 COP 95% confidence ellipse area 모두에서 눈뜨고 외발서기가 눈감고 외발서기보다 작게 나타나 시각이 균형 제어 능력에 영향을 미치는 것으로 나타났다. COP 95% confidence ellipse area는 균형 제어 능력 평가 시 분별력이 높은 변수로 생각되며, 차후 다양한 그룹과 많은 대상자를 이용하여 다른 변수들 간의 비교 분석을 통한 추가 연구가 기대된다.
