The conduction velocity of peripheral nerves is an indication of their growth. Ulnar nerve conduction velocity, forearm length, postpartum age and weight were measured in 25 monkeys (Macaca nemestrina) to determine the best way to estimate gestational age. Correlation analysis showed that while conduction velocity is strongly correlated with gestational age (r = 0.68), both forearm length (r = 0.91) and weight (r = 0.94) are more strongly correlated. Of the three simple measurements made, weight provides the best estimate of gestational age.
周围神经的传导速度是其生长情况的一个指标。对25只豚尾猴（食蟹猴）测量了尺神经传导速度、前臂长度、产后年龄和体重，以确定估计胎龄的最佳方法。相关性分析表明，虽然传导速度与胎龄有很强的相关性（r = 0.68），但前臂长度（r = 0.91）和体重（r = 0.94）的相关性更强。在进行的三项简单测量中，体重对胎龄的估计最为准确。
