针刺治疗面神经麻痹对神经电生理的影响

目的 探讨针刺治疗面神经麻痹的机理。方法 将48例面神经麻痹患者进行针刺治疗前后自身对照，通过神经肌电图测试观察针刺前后神经肌电图的变化。结果 面神经直接刺激：潜伏期、诱发电位波幅与针刺前比较，P〈0.01；瞬目反射：潜伏期R1、R2波与针刺前比较，P〈0．01；R1诱发电位与治疗前比较，P〈0．01；针刺后上述指标与健侧比较，P〉0．05。结论 针刺治疗面神经麻痹，对已损伤面神经电生理有明显的改善作用，可使其恢复到正常水平。

The influence of acupuncture on neural electrophysiology in treating facial paralysis

Objective To investigate the mechanism of acupuncture treatment of facial paralysis.Methods An auto-comparison was made in 48 facial paralysis patients between before and after acupuncture treatment.Neuro-myoelectric changes were observed by electromyography after acupuncture.Results Direct stimulation of the facial nerve: Evoked potential amplitude in the latent period was significantly different from that before acupuncture(P<(0.05));nictitation reflex: R_1 and R_2 waves in the latent period were significantly different from those before acupuncture(P<(0.01));R_1 evoked potential was significantly different from that before treatment(P<(0.01));after acupuncture,the above indices were not significantly different from those on the healthy side(P>(0.05)).Conclusion In treating facial paralysis,acupuncture significantly improves the electrophysiology of the injured facial nerve and restores it to a normal level.
