水中运动训练对膝骨性关节炎临床症状的有效缓解作用

Research in application value of aquatic exercise in knee osteoarthritis

目的探讨水中运动疗法对膝骨性关节炎(knee osteoarthritis,KOA)患者膝关节功能的影响。方法选择2013年1月至2016年1月某院收治的KOA患者62例,采用暗箱信封法,根据单双号将患者随机分为观察组和对照组。观察组行水中运动训练,对照组行徒手运动训练。观察两组治疗后膝关节功能改善情况。结果与治疗前相比,两组患者膝关节伸展、髋关节外展、肌肉力量和膝关节功能水平在治疗后1个月、3个月均显著改善(P<0.05)。与对照组相比,观察组患者的膝关节伸展、髋关节外展、肌肉力量和膝关节功能随着时间的推移均产生积极的变化,两组之间差异具有统计学意义(P<0.05)。两组患者在治疗期间均无不良反应发生。结论采用水中运动训练KOA患者,能有效改善患者的膝关节功能,具有重要的应用价值。

Objective To study the application value of aquatic exercise in the knee joint function in patients with knee osteoarthritis（KOA）.Methods A total of 62 patients with KOA were enrolled from January 2013 to January 2016 and were divided into observation group（n=31） and control group（n=31） rand omly according to camera obscura envelopemethod.Aquatic exercise was applied in observation group,and unarmed exercise was carried out in control group.The improvement of knee function after treatment in both groups were observed.Results Compared to those before the treatment,the knee extension,hip abduction,muscle strength,and knee function were significantly improved in both groups at 1 month and 3 months after the treatment（P〈0.05）.Compared to those in the control group,the knee joint extension,hip abduction,muscle strength,and knee function in the observation group had a positive change with the time,and the difference was statistically significant（P〈0.05）.No adverse effect occurred in patients of both groups.Conclusion Aquatic exercise has a significant curative effect for the improvement of knee function in the patients with KOA,and it has important application value.
