Abstract

The objective of this study was to effect of Tai Chi on balance and muscle activity of ankle joints with USN sensor in elderly people. Thirty six elderly participated and randomly assigned to a experimental group with Tai Chi and control group. The experimental group trained using a Tai Chi through 3 times per a week over 6 weeks. For all subjects, their balance such as functional reach test and one leg stance test, the change of muscle activity of ankle joints with USN sensor wireless-electromyogram during leg closed stance with eye closed were measured, and the results were as followed. The results were of a signigicant changes to the balance in group and between group as well. Comparison of muscle activity left tibialis anterior and left gastrocnemius in group, there were significant difference. Comparison of muscle activity right tibialis anterior and right gastrocnemius in group, there were significant difference. Comparison of muscle activity between groups, there was significant difference. Additional results indicated that, elderly people who received Tai Chi in one study, improve balance control and muscle activity ankle joint. so it is anticipated that improvement in clinical utilization for the elderly who's gait ability and balance ability reduced.

본 연구는 태극권이 노인의 균형과 센서 USN을 이용하여 발목관절 근활성도에 미치는 영향을 알아보기 위해 다음과 같이 실시하였다. 대상자는 65세 이상 노인 36명을 태극권을 시행한 실험군과 태극권을 하지 않은 대조군을 각각 18명씩 무작위 배정하였다. 실험군은 태극권을 주 3회 6주 동안 18회 실시하였다. 모든 대상자는 실험 전과 실험 후에 정적 및 동적균형검사와 센서 USN을 이용하여 발목관절 근활성도 변화를 측정하였다. 정적균형은 기능적 뻗기 검사, 동적균형은 외발서기검사 그리고 발목관절 근활성도 측정은 눈을 감고 발을 모아 서있는 자세에서 안뜰계에 평류안뜰 자극을 적용한 상태에서 측정하였다. 연구결과, 정적 및 동적균형 모두 두 집단 간 통계적인 차이를 나타냈고, 발목관절 근활성도 분석도 통계적으로 유의한 차이가 나타났다. 따라서 태극권이 노인에게 균형과 발목관절 근활성화에 효과적임을 알 수 있었다.
