电针促进周围神经功能康复的实验研究

目的 探讨电针对受损伤的周围神经功能恢复的影响。方法 Wistar大鼠60只切断左侧坐骨神经并缝合，随机分成对照组与实验组。实验组每天穴位电针20分钟。分别于术后2、4及8周动态观察神经电生理、肌力及坐骨神经功能指数的变化。对照组不作任何处理。结果 实验组神经肌肉动作电位（MAP）、运动神经传导速度（MNCV）均优于对照组（P＜0．01）；排肠肌收缩力明显增强（P＜0．05）；坐骨神经功能指数明显升高（P＜0．05）。结论 穴位电针能促进受损周围神经的功能康复。

EXPERIMENTAL STUDY ON FUNCTIONAL REHABILITATION OF PERIPHERAL NERVE WITH ELECTRIC ACUPUNCTURE

Objective To observe the functional rehabilitation of injured peripheral nerve with electric acupuncture. Methods Sciatic nerve injury model was established by transection of left sciatic nerve in 60 Wistar rats,which were randomly divided into two groups. The experimental group was treated with electroacupuncture, no treatment in the control group. Change of nerve electrophysiological, power of muscle and sciatic functional index (SFI) were observed. Results Nerve muscle action potential (MAP)and motor nerve conduction velocity (MNCV) in the experimental group were better than that of the control group( P<0 01) . The single muscle twitch and tetanization of gastrocnemius muscle were higher in the experimental group too ( P <0.05).SFI were significantly higher in the experimental group( P <0.05). Conclusion Electric acupuncture therapy can improve functional rehabilitation of injured peripheral nerve.
