运动控制训练对女大学生髌股关节痛的影响研究

Research on the Effect of Motor Control Exercise on Patellofemoral Pain in Female College Students

目的:评价运动控制训练(MCE)对女大学生髌股关节痛(PFP)的疗效。为PFP的治疗提供理论依据。方法:将36名受试者随机分为实验组(MCE组)和对照组,各18人。对照组进行假干预。实验组进行MCE。每周训练3次,共6周。分别在干预前和干预后记录单腿深蹲(SLS)时的臀中肌和臀大肌肌电均方根以及动态膝外翻角(DKV)数据,评估膝关节Lysholm量表、视觉模拟评分(VAS)及Y平衡。结果:干预6周后,对照组各项指标均无显著性变化(P>0.05);MCE组各项指标除Y平衡的后外侧、后内侧最大伸展距离无统计学变化,其余各指标均有显著性改善(P<0.05);MCE组除Y平衡外,各项指标均优于对照组(P<0.05)。结论:MCE可以增强PFP女大学生臀部肌肉激活、降低DKV角,改善下肢姿势控制、减轻疼痛和提高膝关节功能。

Objective:To evaluate the efficacy of motor control exercise(MCE)in alleviating patellofemoral pain(PFP)among female college students and to provide a theoretical basis for the treatment of PFP.Methods:Thirty six participants were randomly assigned to either the MCE group(n=18)or the control group(n=18).The control group underwent a sham intervention,while the experimental group engaged in MCE.Training sessions were conducted three times per week over a period of six weeks.Record the root mean square and dynamic knee valgus angle(DKV)data of the gluteus medius and gluteus maximus muscles during single leg squat(SLS)before and after intervention,and evaluate the knee joint Lysholm scale,visual analog scale(VAS),and Y balance.Results:After six weeks of intervention,no significant changes in various indicators in the control group(P>0.05).All indicators in the MCE group showed significant improvement(P<0.05)except for the maximum extension distance of the posterior lateral and posterior medial sides of Y balance,which showed no statistical change;Except for Y balance,all indicators in the MCE group were better than those in the control group(P<0.05).Conclusion:MCE can enhance hip muscle activation,reduce the DKV,improve lower limb postural control,alleviate pain,and enhance knee joint function in female college students with PFP.
