摘　　要：目的观察针刺对髌股关节疼痛综合征患者疼痛的直接效应,以及对股内侧斜肌和股外侧肌肌电比率的影响。方法采用针刺治疗25例髌股疼痛综合征患者。所有患者在开始治疗前和治疗3周后进行阶梯任务实验,利用表面肌电仪对股内侧斜肌和股外侧肌的神经肌肉电活动进行评定,同时对膝关节疼痛程度进行评定。结果治疗后患者疼痛明显减轻(P<0.01),向心性收缩与离心性收缩时股内侧斜肌和股外侧肌的神经肌电比率与治疗前比较有显著性差异(P均<0.01)。结论针灸可以明显减轻疼痛,改变股内斜、外侧肌的募集。Objective It is to observe the effects of acupuncture on pain in patients with patellofemoral pain syndrome（PFPS）,and its influence on EMG ratio of vastus medialis obliquus（VMO） to vastus lateralis（VL）.Methods Twenty-five patients with PFPS were received acupuncture treatment five times a week for 3 weeks,step task test was executed before and after treatment,and the surface EMG activity ratio of VMO and VL was determined with surface electrodes,then the intensity of knee pain was evaluated.Results After 3 weeks of acupuncture treatment,the knee pain was significant decreased（P0.01）,and there was significant difference in the VMO/VL EMG ratio of PFPS before and after treatment（P0.01）.Conclusion Acupuncture can reduce the knee pain and improve the recruitment of VMO and VL of patients with PFPS.
