关于健康成人左右运动神经传导参数的比较

目的：研究正常人左、右侧的末梢神经传导特点及易损伤性,探讨生活习惯与末梢神经潜在性损伤的内在关联,提高电生理诊断准确率。方法：100名志愿者为对象,检测正中、尺、胫和腓神经的复合肌肉动作电位（CMAP）、F波,观察左、右侧的神经传导参数及左右差值与生活习惯之间的联系。结果：左侧尺、胫运动神经传导速度（MCV）慢于右侧（P值各为0.013、0.011）。MCV≤X-1S尺神经组的远端潜伏期（D Lat）、F波最短潜伏期（F-Lat）延长于MCV〉X-1S组（P值均为0.000）。MCV≤X-1S胫神经组的近端波幅（P Amp）低于MCV〉X-1S组（P=0.000）。右侧腓神经D Lat延长于左侧（P=0.007）,D Lat≥X＋1S腓神经组的MCV、F-Lat平均值慢或延长于D Lat〈X＋1S组（P值各为0.041、0.000）。结论：左侧尺、胫神经MCV慢于右侧,右侧腓神经D Lat延长于左侧。推测神经传导左右差异是由日常生活中的频繁而反复的轻微外伤导致。

Comparison between right and left motor nerves conduction parameters of healthy adults

Objective：Conduction characteristics of healthy people＇s right and left peripheral nerves and features of easily-injured parts in body are studied and inevitable connection between daily living custom and potential injury on peripheral nerves are probed to improve electro-physiological diagnosis.Methods：100 volunteers compound muscle action potential（CMAP） and F-wave of median,ulnar,tibial and peroneal nerves are examined.Conduction Parameters of right and left nerve are compared and the differences between right and left nerves are observed to confirm itsconnecion to living customs.Results：Muscle Conduction Velocity（MCV） of left ulnar and tibial nerves are slower than that of the right（P value is 0.013 and 0.011 respectively）.Distal latency（D Lat） and the shortest F-wave latency（F-Lat） of MCV ≤ X-1S ulnar nerve group is longer than that of MCV X-1S group（both of P value are 0.000）.MCV and F-Lat of of D Lat ≥ X＋1S peroneal nerve group is longer than that of D Lat X＋1S group（P value are 0.041 and 0.000 respectively）.Proximal amplitude（P Amp）of MCV ≤ X-1S tibial nerve group is lower than that of the MCV X-1S group（P=0.000）.D Lat of right peroneal nerve is longer than that of left（P=0.007）,Average values of MCV and F-Lat of D Lat ≥ X＋1S pereoneal nerve group is slower or longer than that of D Lat X＋1S group（P values are 0.041、0.000 respectively）.Conclusions：MCV of left ulnar and tibial nerves are slower than that of the right;D Lat of right peroneal nerve is longer than that of the left.It is conjectured that frequently and repeatedly light injury,which often happens in daily customary living,may lead to conductive difference between right and left nerves.
