双侧正中神经、尺神经多节段运动神经传导各参数正常值的建立

目的：建立双侧正中神经、尺神经多节段运动神经传导速度（MCV）、潜伏期(LAT)和波幅(AMP)的正常值。方法：200例健康志愿者，男100例，女100例，分别按年龄分成5组,正中神经记录点在拇短展肌,刺激点分别为掌点、腕点、肘点、腋点、Erb点；尺神经记录点在小指展肌,刺激点分别为腕点、肘下点、肘上点、腋点、Erb点，记录各段MCV、LAT、AMP值。结果：正中神经、尺神经多节段MCV 、LAT、AMP与性别、侧别无相关性;年龄与正中神经各段MCV、LAT、AMP及尺神经AMP有关。 结论：双侧正中神经、尺神经多节段运动神经传导的准确检测对临床疾病诊断有重要价值。

Establishment of normative value of multiple segments motor nerve conduction velocity of bilateral median nerve and ulnar nerve

Objective: To establish normative value of multiple segments motor nerve conduction of bilateral median nerve and ulnar nerve, including motor nerve conduction velocity (MCV)、latency (LAT)and amplitude (AMP). Method: Two hundred normal volunteers were divided into 5 groups according to different ages. Median nerve was examined at multiple points: palm, wrist, elbow, axilla and Erb's. Ulnar nerve was examined at multiple points: wrist, below elbow, above elbow, axilla and Erb's. The values of segmental MCV, LAT and AMP were recorded. Result: Gender and sidedness had no effect on MCV, LAT and AMP of median nerve and ulnar nerve. However, age had significant effects on MCV, LAT and AMP of median nerve and AMP of ulnar nerve. Conclusion: The examination of multiple segments motor nerve conduction of bilateral median nerve and ulnar nerve possess important value in diagnosis.
