Abstract

The aim of this study was to determine the effect of a non-elastic fixation belt on the balance ability and fall prevention in elderly women. Elderly women experience reduced balance ability and an increased risk of falls due to a weakening of the surrounding sacroiliac joint and pelvic muscles during childbirth and menopause. On the other hand, specific studies are still needed. The subjects were allocated randomly to two groups: control (n=20) and experimental (n=20). The experimental group used a non-elastic fixation belt, whereas the control group had no fixation belt. The balance ability and the fall index were measured in all subjects using a balance measurement device, and the low abdominal muscle thickness was determined in the experimental group using ultrasound imaging for the exact application of the non-elastic fixation belt. The following statistical analysis was performed: an independent t-test for the general characteristics of the subjects, $2{\times}2$ analysis of variance with repeated measures for the balance and fall index score, and a paired t-test for the abdominal muscle thickness. The group ${\times}$ time interaction effect showed significant improvement in the General Stability Index (F1,38=47.24, p=0.001), Fourier Harmony Index (F1,38=88.83, p=0.001), Weight Distribution Index (F1,38=50.21, p=0.001), and Fall Index (F1,38=21.59, p=0.001). The thicknesses of the transverse abdominal (p=0.001) and internal oblique (p=0.001) muscles were increased significantly in the experimental group after using the non-elastic fixation belt. Overall, the application of a non-elastic fixation belt could be effective in improving the balance ability and fall prevention in elderly women.

본 연구의 목적은 노인 여성의 약화된 천장관절 안정화를 위하여 비탄력 고정식 벨트를 적용하여 균형 능력과 낙상예방에 미치는 영향을 알아보고자 하였다. 노인 여성들은 출산과 폐경으로 천장관절의 약화 및 골반 주위근육들의 약화로 인하여 균형능력의 감소와 낙상위험률이 증가된다. 그러나 이와 관련된 연구는 불충분하다. 연구 대상자들은 실험군과 대조군으로 각각 20명씩 무작위로 배정하였으며, 비탄력 고정식 벨트를 실험군에게 적용한 후 균형 측정기를 사용하여 균형능력과 낙상 위험률을 평가하였다. 또한 비탄력 고정식 벨트를 적용한 실험군에서 하복부근육의 근두께를 초음파기기를 사용하여 실험 전후에 측정하였다. 통계방법은 연구대상자의 일반적 특성을 위하여 독립 t-검정, 균형 및 낙상지수를 위하여 $2{\times}2$ 반복 측정 분산분석 및 근두께를 위하여 짝비교 t-검정을 사용하였다. 두 그룹의 교호작용 효과는 안정성 지수(F1,38=47.24, p=0.001), 퓨리에 지수(F1,38=88.83, p=0.001), 체중분포 지수(F1,38=50.21, p=0.001) 및 낙상 지수(F1,38=21.59, p=0.001)에서 모두 통계적으로 유의하게 나타났다. 또한 비탄력 고정식 벨트를 적용한 결과 실험 후 복횡근(p=0.001)과 내복사근(p=0.001)의 근두께는 통계적으로 유의하게 증가하였다. 노인 여성들의 약화된 천장관절의 강화 및 안정화 방법으로 비탄력 고정식 벨트는 균형 및 낙상 예방에 긍정적이며 용이성, 보편성 및 경제적으로 효과적임을 알 수 있었다.
