The Effects of Trunk Stabilization using Sling on Pain and Dynamic Balance in Patients with Chronic Low Back Pain

본 연구의 목적은 만성요통환자에서 슬링을 이용한 몸통 안정화가 통증과 동적 균형능력에 미치는 영향을 확인하는 것이다. 본 연구에서 만성요통환자 47명으로 실험군 24명과 대조군 23명이 참여하였다. 실험군은 슬링을 이용한 몸통 안정화 운동프로그램을 실시하였고, 대조군은 물리치료를 실시하였으며, 두 집단은 6주 동안 일주일에 3번, 1회에 30분 동안 실시하였다. 통증과 동적균형능력의 진행을 평가하기 위해, 프로그램 전과 후에 통증은 시각통증척도와 압통역치를 측정하였다. 또, 동적균형능력은 앞뒤쪽속도와 안가쪽속도를 측정하였다. 측정된 값은 SPSS를 활용하여 t-test와 ANCOVA를 실시하였고, 모든 통계의 유의 수준은 .05로 설정하였다. 본 연구의 결과는 다음과 같다. 첫째, 시각통증척도와 압통역치에서 두집단은 통계적으로 유의한 차이를 보였다. 둘째, 앞뒤쪽속도와 안가쪽속도에서 실험군에서 유의한 차이를 보였다. 셋째, 두집단 간에 측정항목은 큰 변화가 없었다. 결과적으로 슬링을 이용한 몸통 안정화 운동은 만성요통환자의 통증 감소와 동적균형능력 개선됨을 보여주었다. 만성요통환자를 위한 슬링운동법은 효과적이나, 좀 더 효율적인 슬링 운동법 연구가 필요하다.

The purpose of this study was to ascertain the effects of trunk stabilization using sling on pain and dynamic balance in patients with chronic low back pain. Forty-seven subjects participated in this study, these subjects were assigned into two groups, a control group(n=23) and an experimental group(n=24). The subjects in the control group were received a conservative physical therapy and experimental group carried out the trunk stabilization using sling for 30 minutes per day, three times a week during 6 weeks. In order to evaluate the progresses of pain and dynamic balance ability, corresponding variables were measured at two times, pre and 6th week. The pain was assessed by visual analogue scale(VAS) and pressure pain threshold(PPT). The dynamic balance ability was assessed using GOOD BALANCE system. The collected data were analyzed by using SPSS and verified that each data was a normal distribution based on Kolmogorov-Smirnov Goodness-of-fit test. In order to decide the significances of the within-subjects effects and between-subjects effects of pain and dynamic balance ability were ascertained by using paired t-test and ANCOVA. In all statistical analyses, significance level was set by α=.05. The results of this study were as follows; First, VAS in the exercise group before and after the pain in the both groups showed statistically significant difference. PPT in the exercise group before and after pain in the both groups showed statistically significant difference. Second, dynamic balance ability in the exercise before and after, the results of the experimental group in APV and MLV revealed a statistically significant difference. Third, between groups before and after exercise in all items no significant differences of the group comparisons. The above results indicated that a trunk stabilization using sling exercise reduced pain and improved dynamic balance abilities in patients with chronic low back pain. However, in this study, It is difficult to generalize that trunk stabilization using sling exercise application is effective for patients with chronic low back pain. The further studies should be focused at development of various modified forms of the trunk stabilization using sling exercise in keeping up the improvement effect of this exercise.
