广义估计方程评估浮针法联合穴位埋线治疗不同分期膝骨关节炎的疗效

Generalized equation estimation of the therapeutic effect of floating needle therapy combined with acupoint embedding on different stages of human knee osteoarthritis

背景:穴位埋线法和浮针疗法是治疗膝骨关节炎的方法,但关于两种方法联合治疗的效果研究还鲜有报道。目的:运用广义估计方程探讨穴位埋线联合浮针法对不同分期膝骨关节炎的治疗效果。方法:选择2019年2月至2023年2月东莞市中医院收治的膝骨关节炎患者436例作为研究对象,随机分为2组,对照组(n=218)采用浮针法,观察组(n=218)采用穴位埋线法结合浮针疗法。以K-L分期方法为原则进行分期,其中对照组Ⅰ期57例,Ⅱ期62例,Ⅲ期49例,Ⅳ期50例;观察组Ⅰ期48例,Ⅱ期66例,Ⅲ期63例,Ⅳ期41例。比较两组患者治疗前后各指标水平及临床疗效;采用广义估计方程模型分析临床疗效的影响因素以及不同时点、不同方法、不同分期对治疗效果影响的交互效应。结果与结论:①观察组与对照组以及不同分期患者之间的基线资料均无显著差异(P>0.05),具有可比性;②两组患者经过治疗后Ⅰ期患者的治愈率最高,观察组总好转率显著高于对照组;组内比较,不同分期患者治愈率差异均有显著性意义(P<0.05);③两组患者经过治疗后各项指标均显著下降,对照组治疗4周后各指标不同分期患者相比差异均有显著性意义(P<0.05);观察组患者治疗2周后,各项指标不同分期患者相比差异即有显著性意义(P<0.05),且观察组治疗4周后各项指标均低于对照组(P<0.05),治疗效果优于对照组;④广义估计方程模型分析结果显示,创伤史、白细胞介素6水平、治疗方法、治疗时间和K-L分期均显著影响患者的临床疗效;⑤交互效应分析中,治疗2周两组患者中Ⅲ、Ⅳ期的目测类比评分有统计学意义(P<0.05);治疗4周时,两组患者中Ⅱ、Ⅲ、Ⅳ期患者的目测类比评分有统计学意义(P<0.05);⑥提示穴位埋线联合浮针法对不同分期膝骨关节炎的治疗效果优于单独浮针疗法,创伤史、白细胞介素6水平、治疗方法、治疗时间和K-L分期对患者的治疗效果有显著影响。

BACKGROUND:Acupoint embedding and floating needle therapy are two methods for the treatment of knee osteoarthritis,but there are few reports on the combined treatment of the two methods.OBJECTIVE:To investigate the therapeutic effect of acupoint embedding combined with floating needle therapy on different stages of knee osteoarthritis using generalized estimating equations.METHODS:A total of 436 patients with knee osteoarthritis admitted to Dongguan Hospital of Traditional Chinese Medicine from February 2019 to February 2023 were selected as the research subjects.All patients were randomly divided into a control group with floating needle therapy(n=218)and an observation group with acupoint embedding method combined with floating needle therapy(n=218).Staging was performed according to the K-L staging method.In the control group,there were 57 cases in stage I,62 in stage II,49 in phase III,and 50 in stage IV,while in the observation group,there were 48 cases in stage I,66 in stage II,63 in phase III,and 41 in stage IV.The levels of indexes and clinical efficacy were compared between groups before and after treatment.Generalized estimating equation model was used to analyze the influencing factors of clinical efficacy and the interaction effect of different time points,different methods and different stages on therapeutic efficacy.RESULTS AND CONCLUSION:There was no significant difference in baseline data between the observation group and the control group,as well as between the patients of different stages(P>0.05).After treatment,the cure rate of stage I patients was the highest after treatment,and the total improvement rate in the observation group was significantly higher than that in the control group.There were significant differences in the cure rate among different stages in each group(P<0.05).After treatment,all indicators in the two groups were significantly decreased.In the control group,there were significant differences in various indicators of patients at different stages after 4 weeks of treatment(P<0.05).In the observation group,after 2 weeks of treatment,there were significant differences in various indicators of patients at different stages(P<0.05),and all the indexes in the observation were lower than those in the control group after 4 weeks of treatment(P<0.05)and the therapeutic effect in the observation group was better than that in the control group.Generalized estimating equation model analysis showed that trauma history,interleukin-6 level,treatment method,treatment time and K-L stage all significantly affected the clinical efficacy in patients.In the interaction effect analysis,after 2 weeks of treatment,there was a significant difference in the visual analogue scale score between the two groups in stages III and IV(P<0.05).After 4 weeks of treatment,there was a significant difference in the visual analogue scale score between the two groups in stages II,III,and IV(P<0.05).To conclude,acupoint embedding combined with floating needle therapy is superior to floating needle therapy alone in the treatment of different stages of knee osteoarthritis.Trauma history,interleukin-6 level,treatment method,treatment time and K-L stage significantly influence the therapeutic effect.
