The effect of height on nerve conduction velocity (NCV) was studied in 41 normal subjects. Peroneal and sural NCV correlated inversely with height and with estimated axonal length, whereas median motor and sensory NCV failed to show any significant relationship to height. These findings are consistent with the hypothesis of abrupt distal axonal tapering in the lower extremities. Recognition of height effect in the legs is clinically significant, since diagnostic sensitivity of NCV determinations is improved when corrected for height differences. Multiple regression equations derived from the sample data allow satisfactory estimation of peroneal NCV, sural NCV, H-reflex latency, and F-wave latency from height (or axonal length), age, and other important predictors.
对41名正常受试者研究了身高对神经传导速度（NCV）的影响。腓总神经和腓肠神经的NCV与身高及估计的轴突长度呈负相关，而正中神经运动和感觉NCV与身高未显示出任何显著关系。这些发现与下肢远端轴突突然变细的假说一致。认识到腿部的身高效应具有临床意义，因为校正身高差异后，NCV测定的诊断敏感性会提高。从样本数据得出的多元回归方程可根据身高（或轴突长度）、年龄和其他重要预测因素，令人满意地估算腓总神经NCV、腓肠神经NCV、H反射潜伏期和F波潜伏期。
