초록
본 연구는 발목 움직임을 발생시키는 근육들의 근력, 유연성 향상을 위한 운동 프로그램 참여가 다운증후군 아동들의 보행능력과 균형능력에 어떠한 영향을 줄 수 있을지 과학적으로 검증해 보는데 그 목적이 있다. 연구대상은 B광역시에 거주하는 10명의 다운증후군 아동들이 참여하였다. 운동 프로그램 참여 전·후 발뒤꿈치 접지시간 비율 , 보행각도, 발의 회내 비율, 양발서기와 오른발/왼발 외발서기 시 균형능력을 대응표본 t-검정(paired t-test)을 실시하여 측정 변인 간에 사전/사후 결과 차이를 검증 하였다. 그 결과 첫째, 발뒤꿈치가 접촉 시간이 증가되어 발이 흡수하는 충격을 분산 시키는 효과가 있었다. 둘째, 양발 보행각도의 감소로 인해 정상인의 보행각도에 근접한 결과를 보여주었다. 셋째, 양발지지와 오른발/왼발 지지 조건 모두에서 균형능력의 향상을 보였다.
Abstract
The purpose of this study is to scientifically verify how participation in an ankle muscle strength and flexibility training can affect to improve the gait pattern and balance ability of children with Down syndrome. The participants for this study were 10 children with Down's syndrome living in metropolitan city B. The heel contact time ratio, gait angle, more pronated change ratio, and balance ability when standing on both feet and right/left uni-foot standing before and after participating in ankle muscle strength and flexibility training were measured and conducted to a paired t-test to compare the results between pre and post test. As a result, first, the heel contact time ratio was increased, which has the effect of dispersing the shock absorbed by the foot. Second, the gait angle was close to that of a normal person. Third, balance abilities were improved in both foot support and right/left foot support conditions.
