The influence of placental site and parity on the date of quickening was studied in 112 gravidas. With placental site on the anterior uterine wall, quickening occurred at a mean gestational age of 19 weeks in primigravidas, and 17 weeks, five days in multiparas. With placental site on the posterior uterine wall, quickening occurred at a mean gestational age of 18 weeks in primigravidas, and 16 weeks, one day in multiparas. It is concluded that placental site influences quickening independent of parity and that it is a major factor in determining the stage at which fetal movements are first felt.
在112名孕妇中研究了胎盘位置和产次对胎动初觉日期的影响。胎盘位于子宫前壁时，初产妇胎动初觉的平均孕周为19周，经产妇为17周零5天。胎盘位于子宫后壁时，初产妇胎动初觉的平均孕周为18周，经产妇为16周零1天。研究得出结论，胎盘位置独立于产次影响胎动初觉，且是决定首次感觉到胎儿活动阶段的主要因素。
