As decreased foetal movement (FM) may indicate impaired foetal health, FM recording has been suggested as a method of assessing foetal well-being. A non-intrusive, automated method of recording FM (FM-detector), was compared with maternal and ultrasonographic assessment of FMs in 24 women in the third trimester of pregnancy. The FM-detector detected a greater proportion of ultrasonographically recorded FMs than the mothers did (median 70% and 38%, respectively; p less than 0.001). Parity, gestational age, placental site or thickness, maternal weight or the distance from the maternal abdominal surface to the amniotic cavity did not affect the ability of the FM-detector to detect ultrasonographically recorded FMs. The estimation of FM strength by the FM-detector agreed fairly well with the assessment of FM strength by the ultrasound observer. The FM-detector would seem suitable for clinical use, as in the examination of pregnant women complaining of feeling 'less FM'.
由于胎动减少（FM）可能表明胎儿健康受损，因此胎动记录已被建议作为评估胎儿健康的一种方法。在24名妊娠晚期妇女中，将一种非侵入性自动记录胎动的方法（胎动探测器）与母亲对胎动的评估以及超声检查对胎动的评估进行了比较。与母亲相比，胎动探测器检测到的超声记录胎动比例更高（中位数分别为70%和38%；P<0.001）。产次、孕周、胎盘位置或厚度、母亲体重或从母亲腹壁到羊膜腔的距离均不影响胎动探测器检测超声记录胎动的能力。胎动探测器对胎动强度的估计与超声观察者对胎动强度的评估相当一致。胎动探测器似乎适用于临床应用，例如在检查抱怨“胎动减少”的孕妇时。
