摘要： 目的利用表面肌电仪分析髌股疼痛综合征患者康复训练前后股内侧斜肌(VMO)和股外侧肌(VL)肌电活动的变化。方法26例髌股疼痛综合征患者随机分为神经肌电生物反馈训练组(A组)和单纯训练组(B组)各13例,均接受相同的家庭训练,但A组患者在神经肌电生物反馈仪配合下进行训练。所有患者在开始训练前和训练8周后,利用表面肌电仪对VMO和VL的神经肌肉电活动进行连续6h评定,同时对膝关节疼痛程度进行评定。结果治疗后,B组患者的VMO/VL神经肌电比率与治疗前比较差异无显著性意义(P>0.05),而A组患者的VMO/VL神经肌电比率与治疗前比较差异有显著性意义(P<0.05)。结论采用神经肌电生物反馈仪配合髌股疼痛综合征患者的康复训练可促进股内侧斜肌的募集。

Abstract: Objective To analyze electromyographic (EMG) activities of vastus medialis obliquus (VMO) and vastus lateralis (VL) in patients with patellofemoral pain syndrome (PFPS) before and after an exercise program.Methods 26 subjects with PFPS were randomly divided into the EMG biofeedback plus exercise group (group A) and exercise only group (group B) with 13 cases in each group. All patients in two groups were trained with family exercise program, but the patients of the group A used a EMG biofeedback while training. The relative activities of VMO and VL of all patients in two groups were assessed with the EMG apparatus for a continuous 6 hours period before and 8 weeks after training. At the same time the intensity of the knee pain was also assessed.Results There was no statistics difference in VMO/VL EMG ratio of the group B ( P>0.05), whereas the group A had significantly higher VMO/VL EMG ratio ( P<0.05).Conclusion The EMG biofeedback apparatus used in home exercise program of PFPS patients can improve the recruitment of VMO.
