다국어 초록 (Multilingual Abstract)

[PURPOSE] The purpose of this study was to investigate the effects of tai chi on gait, balance ability, and ankle range of motion in elderly women. [METHODS] Participants were randomly assigned to either tai chi (n=14, 69.8±3.4 years) or control group(n=14, 69.4±3.2 years). Individuals in the tai chi group participated the 24-form simplified tai chi session for 50 minutes a day, 3 days a week for 12 weeks. The control group remained in a sedentary lifestyles and refrained from any type of regular physical activity. The measures, including gait velocity, step length, stride width, Berg 's balance scale, one leg standing with closed eyes, Get-up & Go test, and ankle range of motion were performed before and after the 12-week study period. Two-way repeated measured ANOVA was used to test the effect of tai chi practice on each variable. The statistical significance was set at α = .05. [RESULTS] First, gait velocity(p<.001) and step length(p<.001) were increased, and stride width(p<.001) was decreased after the tai chi exercise program. Second, Berg 's balance scale(p<.001) and one leg standing with closed eyes(p<.01) were increased, and Get-up & Go test(p<.001) was decreased after the tai chi exercise program. Third, left dorsi flexion(p<.001), right dorsi flexion(p<.001), left plantar flexion(p<.001) and right plantar flexion(p<.001) were significantly increased after the tai chi exercise program. [CONCLUSIONS] Our data suggest that tai chi program has positive effects on gait, balance ability, and ankle range of motion in elderly women.

[목적] 본 연구는 태극권이 노인 여성의 보행과 균형능력 및 족관절 운동범위에 어떠한 영향을 미치는지 규명하고 노인의 낙상 예방을 위한 운동 프로그램으로 제시하고자 시행하였다. [방법] 연구대상자는 65세 이상으로 낙상 경험이 없으며 독립적인 일상생활이 가능한 노인 여성 28명이며, 이들 중 태극권 집단(n=14, 69.8±3.4세)과 통제 집단(n=14, 69.4±3.2세)으로 구분하여 사전과 사후 동일한 방법으로 보행능력 검사(보행속도, 보장 및 보폭), 균형능력 검사(버그 균형 척도, 동적 균형 및 정적 균형) 및 족관절 운동범위 검사(배측굴곡과 족저굴곡)를 실시하였다. 태극권 집단은 12주간, 주 3회, 50분간 간화태극권 24식을 실시하였다. 반면 통제 집단은 실험기간 동안 규칙적인 운동을 참여하지 않았다. 결과는 반복측정에 의한 이원변량분석을 이용하여 분석하였으며 유의적 수준은 α = .05로 설정하였다. [결과] 첫째, 보행능력의 보행속도(p<.001)와 보장(p<.001)은 유의하게 증가하였으며 보폭(p<.001)은 유의하게 감소하였다. 둘째, 균형능력의 버그 균형 척도(p<.001)와 정적 균형의 눈감고 한발서기(p<.01)는 유의하게 증가하였으며 동적균형의 의자에서 일어나 3m 걸어갔다 돌아오기(p<.001)는 유의하게 감소하였다. 셋째, 족관절 운동범위의 좌측 배측굴곡(p<.001)과 우측 배측굴곡(p<.001) 및 좌측 족저굴곡(p<.001)과 우측 족저굴곡(p<.001)은 유의하게 증가하였다. [결론] 태극권은 낙상 위험과 연관이 있는 노인 여성의 보행과 균형능력 및 족관절 운동범위 증진에 긍정적인 영향을 미친다고 생각된다. 따라서 노인의 신체적 기능 증진을 목적으로 권장되고 있는 태극권은 낙상 예방에도 효과적인 중재전략으로 활용할 수 있다고 본다.
