Abstract

Background: Knee osteoarthritis (KOA) is a common degenerative articular disease that causes disability and poor quality of life (QoL) of the individuals. Electrotherapeutic agents such as therapeutic ultrasound (US), interferential current (IFC), and infrared radiation are used in the treatment. It is not clear which of these agents is the best in improving these variables.

Objective: The study aimed to compare the effects of the combined application of US and IFC therapies and infrared radiation on pain, functional activities, and QoL in people with KOA.

Methods: In a randomized controlled study, 60 participants were randomized into two groups, the combination therapy group (CTG) and the infrared radiation group (IRG). Each group received 15-min treatment three times per week for 12 weeks. The visual analog scale (VAS) was used to assess the pain, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) for functional activities and the Short Form Health Survey questionnaire for QoL.

Results: Participants in the CTG had a significant $(p < 0.05)$ reduction in pain and significant $(p < 0.05)$ improvement in functional activities and QoL compared to the IRG.

Conclusion: The results of this study support the use of the combination of IFC and US therapies to reduce pain and improve function and QoL for KOA patients.

联合治疗和红外辐射对膝关节骨关节炎患者疼痛、身体功能和生活质量的影响:一项随机对照研究。

背景:膝关节骨关节炎(KOA)是一种常见的退行性关节疾病，可导致个体的残疾和生活质量(QoL)下降。电疗药物如治疗超声(US)、干扰电流(IFC)和红外辐射用于治疗。目前尚不清楚哪种药物在改善这些变量方面效果最好。目的:本研究旨在比较US和IFC联合应用治疗和红外辐射对KOA患者疼痛、功能活动和生活质量的影响。方法:采用随机对照研究，将60例患者随机分为联合治疗组(CTG)和红外放疗组(IRG)。每组治疗15分钟，每周3次，连续12周。采用视觉模拟量表(VAS)评估疼痛，采用西安大略和麦克马斯特大学骨关节炎指数(WOMAC)评估功能活动，采用简短健康调查问卷评估生活质量。结果:CTG的参与者有显著的差异(p < 0.05)。(p < 0.05)疼痛减轻，差异有统计学意义(p < 0.05)。与IRG相比，功能活动和生活质量的改善。结论:本研究结果支持IFC联合US治疗可减轻KOA患者的疼痛，改善功能和生活质量。
