Abstract

The purpose of this study was to investigate the effects of the Otago exercise program on physical function and risk of falling in elderly who have experienced falls. Thirty-six elderly people who had experienced falls more than once were randomly classified into an experimental group and control group. Each group exercised 30 minutes three times per week for a total of 8 weeks. Measurements were made using Tetrax to assess risk of falls. In addition, to measure physical function, static balance was measured using Biorescue, dynamic balance was measured using TUG, walking ability was measured using 10 MWT, and lower extremity strength was measured using FTSST. A paired t-test was conducted to verify the difference between before and after exercise in each group, and an independent t-test was performed for comparison between the groups. Regarding the experimental and control groups, static balance ability and dynamic balance ability increased significantly after exercise, and risk of falls decreased (p<.05). Lower extremity strength and gait ability increased significantly after exercise only in the experimental group (p<.05). Based on these results, the Otago exercise program is effective in improving physical function and reducing risk of falls in elderly people who have experienced falls.

본 연구는 오타고 운동프로그램이 낙상 경험 노인의 신체기능 및 낙상 위험도에 미치는 영향을 알아보고자 실시하였다. 낙상을 1회 이상 경험한 노인 36명을 대상으로 각각 오타고 운동프로그램 집단(실험군)과 일반적인 균형훈련집단(대조군)으로 무작위 분류하였다. 각 집단은 30분씩 주 3회, 총 8주 동안 운동을 실시하였다. 낙상의 위험성을 평가하기 위해 Tetrax를 사용하여 측정하였다. 또한, 신체기능의 측정을 위해 정적균형은 Biorescue, 동적균형은 TUG, 보행능력은 10MWT, 하지근력은 FTSST를 이용하여 측정하였다. 각 그룹 내 운동 전·후 차이를 검증하기 위하여 대응표본 t-검정(Paired T-test)을 실시하였고, 그룹 간의 비교를 위하여 독립표본 t-검정(Independent Sample T-test)을 실시하였다. 실험결과, 실험군, 대조군 모두 정적균형능력 및 동적균형능력은 운동 후 유의하게 증가하였으며, 낙상의 위험성은 감소하였다(p<.05). 하지근력 및 보행능력은 실험군에서만 운동 후 유의하게 증가하였다(p<.05). 본 연구의 결과를 종합해보면, 오타고 운동프로그램은 낙상 경험 노인의 신체기능 증진 및 낙상의 위험성이 감소에 효과적이라는 것을 알 수 있었다.
