基于肌筋膜理论的手法联合电针治疗髌股疼痛综合征的临床观察OA

Objective:To observe the clinical efficacy of manual therapy based on myofascial chain theory combined with electroacupuncture in the treatment of patellofemoral pain syndrome(PFPS).Methods:Sixty patients with PFPS admitted from September 2024 to August 2025 were enrolled and randomly divided into a manual therapy group and a control group,with 30 cases in each group.During the study,2 cases in the manual therapy group and 4 cases in the control group dropped out.Finally,28 cases in the manual therapy group and 26 cases in the control group completed the trial.The manual therapy group received myofascial manual therapy combined with electroacupuncture,while the control group received placebo manual therapy combined with electroacupuncture.Manual therapy was administered for 20 minutes after each acupuncture session,3 times a week for a total of 2 weeks.The NRS pain score,Kujala score,Lysholm score,painless active knee flexion range of motion,and the electromyographic ratio of the vastus medialis to vastus lateralis muscles on the affected side were compared between the two groups before and after intervention.Results:Before intervention,there were no significant differences in NRS score,Kujala score,Lysholm score,painless active knee flexion range of motion,or the electromyographic ratio of vastus medialis to vastus lateralis between the two groups(P>0.05).After 4 weeks of intervention,the NRS scores in both groups were significantly lower than those before intervention(P<0.05),and the NRS score in the manual therapy group was lower than that in the control group(P<0.05).In the manual therapy group,the Kujala score,Lysholm score,and painless active knee flexion range of motion were significantly increased compared with baseline(P<0.05).In the control group,only the painless active knee flexion range of motion was improved(P<0.05),while the changes in Kujala score and Lysholm score were not statistically significant(P>0.05).The Kujala score,Lysholm score,and painless active knee flexion range of motion in the manual therapy group were higher than those in the control group(P<0.05).The electromyographic ratio of vastus medialis to vastus lateralis on the affected side was significantly decreased in the manual therapy group(P<0.01),whereas no significant change was observed in the control group(P>0.05).Moreover,this ratio in the manual therapy group was lower than that in the control group(P<0.01).Conclusion:Manual therapy based on myofascial chain theory combined with electroacupuncture yields significant clinical effects in the treatment of PFPS.It can effectively relieve pain,improve knee joint function,and increase the painless active knee flexion range of motion in patients.
