经筋针刺法联合益肾壮骨方治疗膝关节骨性关节炎的效果及表面肌电图分析

Effect and surface electromyography analysis of sinew needling method combined with Yishen Zhuanggu Decoction in the treatment of knee osteoarthritis

目的探究经筋针刺法联合益肾壮骨方治疗膝关节骨性关节炎(KOA)的效果及表面肌电图分析。方法选取2022年3月至2023年3月北京市鼓楼中医医院收治的74例KOA患者作为研究对象,按照随机数字表法分为观察组(37例)与对照组(37例)。对照组采用益肾壮骨方治疗,观察组在对照组的基础上联合经筋针刺法治疗。比较两组患者治疗前后的中医证候积分、膝关节功能(Lysholm评分)、视觉模拟评分法(VAS)评分与表面肌电图指标。结果治疗后,观察组中医证候积分各维度评分低于对照组,差异有统计学意义(P<0.05)。治疗后,观察组VAS评分低于对照组,Lysholm评分高于对照组,差异有统计学意义(P<0.05)。治疗后,观察组伸展Mean值高于对照组,协同收缩比率低于对照组,差异有统计学意义(P<0.05)。结论经筋针刺法联合益肾壮骨方能缓解膝关节骨性关节炎患者中医证候积分,降低疼痛程度,提高膝关节功能,改善患者表面肌电图指标,值得推广。

Objective To explore the effect and surface electromyography(sEMG)analysis of sinew needling method combined with Yishen Zhuanggu Fang in the treatment of knee osteoarthritis(KOA).Methods A total of 74 KOA patients were admitted to Beijing Gulou Hospital of Traditional Chinese Medicine from March 2022 to March 2023 as research subjects,and divided into observation group(37 cases)and control group(37 cases)according to the random number table method.The control group was treated with Yishen Zhuanggu Decoction,the observation group was treated with sinew needling method on the basis of the control group.The traditional Chinese medicine(TCM)syndrome scores,knee function(Lysholm scores),visual analogue scale(VAS)and sEMG of the two groups before and after treatment were compared.Results After treatment,the scores of TCM syndrome in the observation group was lower than that of the control group,and the difference was statistically significant(P<0.05).After treatment,the VAS scores of observation group was lower than control group,Lysholm scores was higher than control group,and the differences were statistically significant(P<0.05).After treatment,the Mean of extension in the observation group was higher than that in the control group,and the co-contraction ratio was lower than that in the control group,and the differences were statistically significant(P<0.05).Conclusion Sinew needling method combined with Yishen Zhuanggu Decoction can relieve the TCM syndrome scores of patients with KOA,reduce the degree of pain,improve the function of knee joint,and improve the sEMG index of patients,which is worth popularizing.
