Objectives This study aims to examine the changes in balance ability and pain through water bag exercise in middle-aged women with chronic low back pain, providing foundational data and suggesting effective exercise programs. Methods Participants were middle-aged women with chronic low back pain who had no history of lumbar surgery in the past year and volunteered to participate. 10 subjects were selected. The Functional Reach Test (FRT) and the distance of center of pressure (COP) movement at the highest reach point during FRT performance were measured. Additionally, the effects of water inertial load exercise were examined through the Visual Analogue Scale (VAS) pain index test. The exercise intervention was conducted twice a week for 50 minutes over 8 weeks. This study focused on a case report without a control group, and data were processed and analyzed using a paired t-test to compare pre-post intervention dependent variables. Results The FRT test results showed an significant decrease in COP values in all directions(anterior-posterior and mediolateral) at the highest reach point(p<.001), with a significant increase in FRT distance(p<.01). There was no significant difference in COP values during FRT performance before and after exercise. The VAS results showed a significant reduction in pain perception after exercise(p<.01). Conclusions The study found that middle-aged women with chronic low back pain experienced a reduction in pain perception and improvement in balance ability after implementing an exercise program using water inertia load. The water inertia load exercise was found to be effective not only in enhancing muscle strength but also in improving reflexive balance control ability, suggesting its utility in preventing and reducing low back pain.

본 연구의 목적은 만성요통을 가진 중년여성들에게 물의 관성 부하를 이용한 운동 프로그램이 균형 능력과 시각 적 통증 척도(VAS)에 미치는 영향을 알아보기 위해 실행하였다. 연구대상자는 최근 1년 이내 요부 수술 병력이 없는 만39세에서 만49세까지의 만성요통 환자 10명으로, 8주간 주 2회, 총 50분씩 워터백 운동을 실시하였다. 기능적 도달 검사(FRT) 거리와 FRT의 최고 도달지점의 압력중심점(COP)의 이동거리, 그리고 시각적 통증 척도(VAS)를 통해 운동 의 효과를 평가하였다. 통계처리는 SPSS 28.0을 이용하여 평균 및 표준편차를 산출하고 대응표본 t검정 분석을 실시 하였다. 검사 결과, 운동 후 FRT 거리는 유의하게 증가하였고(p<.01), FRT의 최고 도달지점에서의 COP 값은 앞뒤· 좌우 모든 방향에서 유의하게 감소하였다(p<.001). 요통에 대한 시각적 통증 척도(VAS) 결과는 운동 후 유의하게 감소 하여(P<.01), 물의 관성 부하 운동이 만성요통을 가진 중년여성들의 통증 감소와 균형 능력 향상에 효과적임을 확인하였다.
