目的 测定正常人前臂后皮神经感觉传导正常值.方法 采用逆向法检测58例正常健康人及1例男性伴前臂后皮神经损伤患者的双侧前臂后皮神经感觉传导,记录感觉神经动作电位(SNAP)的起始潜伏期、峰潜伏期、峰峰波幅和传导速度,并计算正常健康人双侧波幅比值.结果 正常健康人前臂后皮神经SNAP的起始潜伏期、峰潜伏期、波幅及传导速度分别为(1.96 ±0.12)ms、(2.48±0.14)ms、(7.39±2.36) μV、(61.39±3.69) m/s,双侧波幅比值(低值/高值)为0.88 ±0.09,左右侧间比较,差异无统计学意义(P＞0.05).各年龄峰潜伏期和波幅的组间比较,差异亦有统计学意义(P＜0.05),而起始潜伏期和传导速度组间无统计学意义(P＞0.05).该例男性患者的前臂后皮神经SNAP波幅和传导速度左侧为1.4 μV和54.5 m/s,右侧为5.8 μV和61.2 m/s.结论 前臂后皮神经的感觉传导测定易于操作,随着年龄增长,SNAP峰潜伏期逐渐延长,波幅逐渐降低,应根据不同年龄段选择正常参考值.

Objective To determine normal reference values for conduction in the posterior antebrachial cutaneous nerve.Methods Antidromic sensory conduction examinations of the bilateral posterior antebrachial cutaneous nerve were conducted with fifty-eight healthy subjects.The onset latency,peak latency,peak-to-peak amplitude and conduction velocity of the sensory nerve action potentials (SNAPs) were recorded and the inter-side ratios of the peak-to-peak amplitudes were calculated.Results The observed means (and standard deviations) of the onset time,the peak latency,the amplitude and the conduction velocity were 1.96 (0.12) ms,2.48 (0.14) ms,7.39 (2.36) μV and 61.39 (3.69) m/s,respectively.The side-to-side amplitude ratio (smaller/larger) was 0.88 ± 0.09,and no significant difference was observed between the left and right side.The average peak latency and amplitude were significantly different for different age groups.There was no statistically significant difference among the age groups with regard to onset latency or conduction velocity.Conclusion Conduction in the posterior antebrachial cutaneous nerve is easy to study.The peak latency is prolonged and the amplitude decreases with age,suggesting that different normal reference values should be established for different age groups.
