摘要
目的:观察电针治疗膝骨关节炎的疗效,探讨电针促进软骨修复的作用。方法:膝骨关节炎患者30例60膝,按随机数字表随机分配到电针组和理疗组各15例30膝。电针组采用电针治疗,穴取内膝眼、犊鼻、鹤顶、血海等,隔日1次;理疗组采用电脑中频治疗仪治疗,每日1次。两组均治疗4周。采用Lysholm膝关节评分标准(LKSS)对治疗前后膝关节功能进行评分并比较,同时采用GE Signa EXCITE Twin Speed HD 1.5T超导磁共振仪进行治疗前后膝关节MRI检查,观察胫股关节软骨10个亚区T2值的变化。结果:电针组和理疗组都是除支撑一项外,LKSS总评分及各单项评分较治疗前明显改善(P<0.01,P<0.05),且电针组治疗后对LKSS总评分和失稳感、肿胀方面的改善要优于理疗组(均P<0.05),其余各项组间差异无统计学意义(P>0.05)。电针组治疗后胫骨外侧前区(LTa)T2值较治疗前显著下降,差异具有统计学意义(P<0.05),其余各区治疗前后T2值差异均无统计学意义(P>0.05);理疗组治疗前后各区T2值无显著变化(P>0.05)。结论:电针能有效改善膝骨关节炎患者的临床症状、体征及膝关节活动功能,疗效优于物理疗法,是较佳的治疗骨关节炎的非手术疗法;电针对软骨磁共振T2值也有一定的影响,提示可能具有促进软骨修复作用。
ABSTRACT Objective To observe therapeutic efficacy of osteoarthritis treated by electroacupuncture, and ex- plore its function of promoting cartilage restoration. Methods According to random digital table, sixty cases of knee osteoarthritis （60 knees） were randomly divided into an electroacupuncture group and a physiotherapy group, 15 cases （30 knees） in each one. The electroacupuncture was applied at Neixiyan （EX-LE 4）, Dubi （ST 35）, Heding （EX-LE 2） and Xuehai （SP 10） in the electroacupuncture group, once every other day. The physiotherapy group was treated by medium-frequency therapeutic apparatus every day. For both groups, 4 weeks of treatment were required. The Lysholm knee scoring scale （LKSS） was used to evaluate and compare the knee joints function before and after treatment. At the same time, the GE Signa EXCITE Twin Speed HD 1.5T was used to take MRI examination of knee joints, and measure the T2 values in 10 sub-regions of the cartilage of tibiofemoral joints. Results Compared before treatment, the LKSS score of both groups were improved with significant differences except item demands for support （P0.01, P0.05）. Between the two groups after treatment, there were sig- nificant differences on total score, item instability and swelling （all P0.05）, the electroacupuncture group was better than the physiotherapy group, but no significant difference on the other items （all P0.05）. In the elec- troacupuncture group after treatment, T2 value in anterior lateral tibial sub-region （LTa） was significantly lowered （P0.05）, but no significant difference in the other nine sub-regions （all P0.05）. In the physiotherapy group,T2 value in any sub-region was not significantly different before and after treatment （all P〉0.05）. oncmslon Electroacupuncture could effectively improve the symptom, sign and knee joint＇s function of patients with knee os- teoarthritis. Compared with physiotherapy, it has more superior effect and considered as a better non-operative treatment for osteoarthritis. Electroacupuncture also has positive influence on T2 value in cartilage, indicating that electroacupuncture may have the function of promoting cartilage restoration.
