目的 观察动力灸治疗肝肾亏虚型膝骨关节炎（knee osteoarthritis ，KOA）的临床疗效。方法 将符合纳入标准的60例肝肾亏虚型KOA患者随机分为试验组与对照组，每组30例。试验组给予动力灸治疗，对照组予以普通针刺治疗，两组均每天治疗1次，连续治疗21 d为1个疗程。1个疗程结束后比较两组患者治疗前后视觉模拟量表（visual analogue scale，VAS）评分、西安大略和麦克马斯特大学骨关节炎指数（the Westem Ontario and McMaster Universities Osteoarthritis Index, WOMAC）、中医证候评分及临床疗效，并记录两组不良反应情况。结果 治疗后两组患者VAS评分、WOMAC评分、中医证候评分较治疗前均明显改善（P<0.05），且试验组改善程度明显优于对照组（P<0.05）；试验组临床疗效明显优于对照组（P＜0.05）。对照组有1例患者出现晕针情况，而试验组患者均未出现不良反应。结论 动力灸治疗肝肾亏虚型KOA疗效确切，不良反应少，能有效地缓解膝关节疼痛，改善患者的生活质量。
Objective To investigate the clinical effect of dynamic moxibustion in the treatment of knee osteoarthritis (KOA) with deficiency of liver and kidney. Methods A total of 60 patients with KOA with deficiency of liver and kidney who met the inclusion criteria were randomly divided into experimental group and control group, with 30 patients in each group. The patients in the experimental group were treated with dynamic moxibustion, while those in the control group were treated with conventional acupuncture, once a day for 21 consecutive days as one course of treatment. After one course of treatment, the two groups were compared in terms of Visual Analogue Scale (VAS) score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, traditional Chinese medicine (TCM) score, and clinical outcome, and adverse reactions were recorded for both groups. Results After treatment, both groups had significant improvements in VAS score, WOMAC score, and TCM symptom score (P<0.05), and the experimental group had significantly better improvements than the control group (P<0.05). The experimental group had a significantly better clinical outcome than the control group (P<0.05). One patient in the control group experienced acupuncture syncope, which was not observed in the experimental group. Conclusion Dynamic moxibustion has a marked clinical effect in the treatment of KOA with deficiency of liver and kidney, with few adverse reactions, and can effectively alleviate the pain of the knee joint and improve patients' quality of life.
