针刺内关、太冲穴治疗膝骨性关节炎

Knee osteoarthritis treated with acupuncture at Neiguan(PC 6) and Taichong(LR 3)

目的:比较针刺内关、太冲穴与常规局部取穴治疗膝骨性关节炎的疗效差异。方法:将44例患者随机分为内关太冲组(20例)和常规组(24例)。内关太冲组针刺健侧内关及患侧太冲穴,若两侧同时患病则取双侧穴位;常规组针刺患侧阳陵泉、阴陵泉、内膝眼、犊鼻、足三里等。运用视觉模拟评分法(VAS)和西安大略和麦克马斯特大学骨关节炎指数(WOMAC)于治疗前、治疗后评估治疗效果。结果:两组治疗后VAS评分及WOMAC疼痛、僵直和功能障碍各项评分均明显低于治疗前(均P<0.001);内关太冲组治疗后VAS评分较常规组下降更明显(P<0.05),两组治疗后WOMAC各项评分差异无统计学意义(均P>0.05)。结论:针刺内关、太冲穴治疗膝骨性关节炎与常规局部取穴治疗疗效相当,但前者取穴更精简、更便捷。

Objective To compare the efficacy difference in the treatment of knee osteoarthritis between acu- puncture at Neiguan （PC 6） and Taichong （LR 3） and the conventional acupoints. Methods Forty four cases were random into a Neiguanc（PC 6） Taichong（LR 3） group observation group （20 cases） and a conventional group con- trol group （24 cases）. In the observention group, acupuncture was applied to Neiguan （PC 6） on the healthy side and Taichong （LR 3） on the affected side. The acupoints were selected bilaterally if both knees were affected. In the control group, acupuncture was applied to Yanglingquan （GB 34）, Yinlingquan （SP 9）, Neixiyan （EX-LE 4）, Dubi （ST 35）, Zusanli （ST 36） and the others on the affected side. The visual analogue scale （VAS） and Western Ontario and McMaster University Osteoarthritis Index （WOMAC） were used for assessment of theraputic effect after treatment. Results The score of VAS and pain, stiffness and function impairment of WOMAC were lower apparently than those before treatment in both groups （all P^0. 001）. VAS score after treatment in the observa- tion group was lower apparently than that in the control group （P〈0.05）. The differences in each item score of WOMAC after treatment were not significant statistically between the two groups （all P〈0.05）. Conclusion Acupuncture at Neiguan （PC 6） and Taichong （LR 3） achieves the similar efficacy on knee osteoarthritis as the conventional acupoints, but the former is more simple and convenient.
