무릎 관절염 환자에게 적용된 수중운동 프로그램이 통증과 신체적 기능에 미치는 효과: 체계적 문헌고찰 및 메타분석

Abstract

Purpose: We aimed to identify the effect of an aquatic exercise program in patients with knee arthritis through a systemic literature review and meta-analysis.

Methods: Searched were conducted on EMBASE, CINAHL, PubMed, Ovid-MEDLINE, and Korean DB up to February 2020, using the keywords "arthritis", "hydrotherapy", "pain", "function", etc. The methodological quality was assessed using the Cochrane's Risk of Bias for randomized studies and the Risk of Bias Assessment tool for non-randomized studies. Data were analyzed using R.3.5.1.

Results: The results showed an overall medium effect size (ES) -0.53 (p<.001) of the aquatic exercise program on pain reduction in patients with knee arthritis. We identified a small effect size of the aquatic exercise program on muscle strength (ES=0.32, p=.003). however, the effect size of physical function was not significant.

Conclusion: Based on our results, the aquatic exercise program has moderate beneficial effects on pain in patients with knee arthritis, and this should be considered in developing this program.
