Currently, there is poor evidence of the effect of hydrotherapy alone on patients with hip or knee osteoarthritis.
The study aimed to assess the impact of hydrotherapy on pain, function, and muscle function in older women with knee osteoarthritis.
A randomized controlled trial was conducted to evaluate the efficacy of hydrotherapy in women with knee osteoarthritis. Seventy-three women aged 65 and older were randomized to hydrotherapy (n=36) or a control group (n=37). The hydrotherapy group received the intervention program in a heated pool (twice per week for six weeks) and an educational protocol while the control group received an educational protocol only. Primary outcomes (before and post-treatment) were pain intensity (0-100) and function (0-100), assessed with the WOMAC questionnaire. Secondary outcomes (before and post-treatment) were knee extensor and knee flexor muscle performance (strength, power, and endurance), assessed by an isokinetic dynamometer. The magnitude of change between the groups for the outcomes was calculated using linear regression models adjusted by baseline outcome values.
The hydrotherapy group had better outcomes for pain (adjusted mean difference=11 points, 95% CI: 3-18) and function (adjusted mean difference=12 points, 95% CI: 5-18). Patients receiving hydrotherapy had better performance for knee flexor and extensor strength, knee flexor power, and knee extensor endurance.
Older women with knee osteoarthritis are likely to have benefits from a course of hydrotherapy exercises. Registry of clinical trials (Trial number RBR-8F57KR) - http://www.ensaiosclinicos.gov.br/rg/RBR-8f57kr/.
目前，单独使用水疗对髋或膝骨关节炎患者的效果证据不足。
本研究旨在评估水疗对老年膝骨关节炎女性疼痛、功能和肌肉功能的影响。
进行了一项随机对照试验，以评估水疗对膝骨关节炎女性的疗效。73 名年龄在 65 岁及以上的女性被随机分为水疗组（n=36）或对照组（n=37）。水疗组在加热泳池中接受干预方案（每周两次，共六周）和教育方案，而对照组仅接受教育方案。主要结局（治疗前后）为疼痛强度（0-100）和功能（0-100），采用 WOMAC 问卷评估。次要结局（治疗前后）为膝关节伸肌和屈肌肌肉性能（力量、功率和耐力），采用等速测力计评估。使用线性回归模型计算组间结局变化的幅度，该模型通过基线结局值进行调整。
水疗组疼痛（调整平均差异=11 分，95%置信区间：3-18）和功能（调整平均差异=12 分，95%置信区间：5-18）的结果更好。接受水疗的患者在膝关节屈肌和伸肌力量、膝关节屈肌功率和膝关节伸肌耐力方面表现更好。
接受水疗锻炼的老年膝骨关节炎女性可能会受益。临床试验注册（试验编号 RBR-8F57KR）- http://www.ensaiosclinicos.gov.br/rg/RBR-8f57kr/。
