电针治疗膝骨关节炎临床对照试验

Observation on therapeutic effects of electroacupuncture for the treatment of knee osteoarthritis

目的:探讨电针对骨关节炎的治疗作用。方法:将40例膝骨关节炎患者按就诊顺序随机分为2组,每组20例。电针组男8例,女12例,平均年龄(62.50±9.23)岁,平均病程(9.85±8.17)年,采用电针治疗;对照组男7例,女13例,平均年龄(61.15±6.75)岁,平均病程(8.60±6.89)年,口服双氯芬酸钠治疗。采用Lysholm膝关节评分标准评定治疗前后膝关节功能。结果:电针组除支撑外,其余各项评分与疗前比较差异均有统计学意义(P<0.01或P<0.05);对照组疼痛度及交锁、膝软与疗前比较差异有统计学意义(P<0.01或P<0.05),其余各项差异无统计学意义(P>0.05)。两组疗后评分在交锁、膝软、肿胀、爬楼梯和下蹲方面差异有统计学意义(P<0.05),而跛行、支撑和疼痛度评分差异无统计学意义(P>0.05)。结论:针刺能有效改善膝骨关节炎患者的临床症状、体征及膝关节活动度,疗效优于口服双氯芬酸钠,是治疗骨关节炎的有效手段。

Objective ：To study the therapeutic effects of electroacupuncture for the treatment of osteoarthritis of knee joint. Methods：Forty patients with knee osteoarthritis were randomly divided into two groups：the electroacupuncture group （20 patients）and the control group （20 patients）. The patients in electroacupuncture group （8 male and 12 female, with an average age of 62.50±9.23 yearn and mean course of disease 9.85±8.17 yearn）were treated with electroacupuncture for one month. At the same time, the patients in control group （7 male and 13 female,with an average age of 61.15±6.75 yearn and mean course of disease 8.60±6.89 yearn）were given Diclofenac sodium orally for one month. The motor function of knee joints were evaluated before and after treatment according to Lysholm knee scoring scale. Results：Most scores in the electroacupuncture group improved significantly compared with those of before treatment（P〈0.01 or P〈0.05 ）except for the item demands for support. While in the control group, compared with those of before treatment, there were significant difference on the item of pain, inter locking and instability （P〈0.01 or P〈0.05）,but there were no significant differences on other five items （P〉0.05）. Between the two groups after treatment,differences on item of inter locking,instability, swelling, stair activity and squat were significant .（P〈 0.05 ）, but no differences on limp,demands for support and pain （P〉0.05）. Conclusion：Acupuncture can effectively improve the clinical symptoms and knee joint＇s motor function of patients with knee osteoarthritis, and more superior than Diclofenac sodium oral. It is a proved effective method for osteoarthritis.
