目的：为了确定髌股疼痛综合征患者的肌电生物反馈治疗的效果，设计：随机对照试验。设置：一所大学转诊中心的研究医院的物理医学和康复科。患者：60例髌股疼痛综合征患者。将患者随机分为两组：生物反馈组（n = 30）和对照组（n = 30）。干预：生物反馈组接受肌电生物反馈训练和常规运动计划，而对照组仅接受常规运动计划。主要结果测量：用生物反馈装置评估股内侧肌和股外侧肌的最大和平均收缩值。采用视觉模拟评分法（VAS）和功能指数问卷（FIQ）分别对患者的疼痛和功能状态进行评估。结果：两组患者治疗后第1个月末的收缩值均较治疗前显著改善。生物反馈组的股内侧肌在所有3个月测量中的平均收缩值;以及股外侧肌在第一个月结束时的平均收缩值显著高于对照组。两组的VAS和FIQ均有显著改善。每月随访显示，没有VAS和FIQ的差异groups.Conclusion：肌电图生物反馈治疗并没有导致进一步的临床改善相比，与传统的运动计划，髌股关节疼痛综合征患者。
Objective: To determine the effects of electromyographic biofeedback treatment in patients with patellofemoral pain syndrome.Design: Randomized controlled trial.Setting: A physical medicine and rehabilitation department in a research hospital of a university referral center.Patients: Sixty patients with patellofemoral pain syndrome. Patients were randomly placed into 2 groups: biofeedback group (ra = 30) and a control group (n = 30).Intervention: The biofeedback group received electromyographic biofeedback training and a conventional exercise program, whereas the control group received a conventional exercise program only.Main Outcome Measures: Maximum and mean contraction values of the vastus medialis and the vastus lateralis muscles were assessed with the biofeedback device. Pain and functional status of the patients were measured by a visual analog scale (VAS) and the Functional Index Questionnaire (FIQ), respectively.Results: Contraction values improved significantly at the end of the first month, compared with the pretreatment values in both groups. Mean contraction values in the biofeedback group of the vastus medialis muscles in all 3 monthly measurements; and the vastus lateralis muscles at the end of the first month, were significantly higher than those of the control group. Significant improvements were shown for both the VAS and the FIQ in both groups. Monthly follow-ups showed no VAS and FIQ differences between the groups.Conclusion: Electromyographic biofeedback treatment did not result in further clinical improvement when compared with a conventional exercise program in patients with patellofemoral pain syndrome.
