During the period 1.10.1979 to 31.1.1981 508 maturity determinations were carried out in 483 infants at the Department of Medical Obstetrics of the Neukölln Hospital in Berlin, using the motor nerve conduction rate of the n. ulnaris in combination with the FARR schema. The median value of the NCR increases from 13.0 m/sec in the 33rd pregnancy week (PW) to 30.4 m/sec in the 44th PW almost in linear progression by 1.58 m/sec per week. Over the entire range the NCR showed a highly significant correlation (r = 0.946 at p greater than 0.00001) with the gestatory age of the infant, whereas the FARR schema differs up to the 38th PW markedly in false-positive direction. Measurement of the motor NCR of the n. ulnaris is evidently a simple and very accurate method for post-partum determination of the gestatory age.
1979年10月1日至1981年1月31日期间，在柏林新克尔恩医院医学妇产科对483名婴儿进行了508次成熟度测定，采用尺神经运动神经传导速率结合FARR模式。神经传导速率（NCR）的中位数从妊娠第33周（PW）的13.0米/秒增加到第44周的30.4米/秒，几乎呈线性增长，每周增加1.58米/秒。在整个范围内，NCR与婴儿的胎龄显示出高度显著的相关性（p大于0.00001时，r = 0.946），而FARR模式在第38周之前在假阳性方向上有明显差异。尺神经运动NCR的测量显然是产后确定胎龄的一种简单且非常准确的方法。
