Nerve conduction velocity was used to measure gestational age in at risk and very-low-birth-weight neonates. The method gave highly significant correlations with gestational estimates by the Dubowitz score and with confirmed maternal dates; 86% of the estimates agreed within two weeks with confirmed maternal dates. The method is valid in babies 30 weeks old or younger and is reproducible after the first postnatal week. There was no difference in babies small for gestational age. The technique was estimated to predict gestation with a standard deviation of +/- 1.14 weeks.
神经传导速度被用于测量高危及极低出生体重新生儿的孕周。该方法与杜波维茨评分法得出的孕周估计值以及与确认的母亲末次月经日期高度相关；86%的估计值与确认的母亲末次月经日期在两周内相符。该方法在30周龄及以下的婴儿中有效，且在出生后第一周后具有可重复性。小于胎龄儿之间没有差异。据估计，该技术预测孕周的标准差为±1.14周。
