Twenty-seven women were studied to assess the relationship between maternally perceived fetal movement and that recorded by a Doppler device. Eighty-eight percent (433 of 492) of maternally perceived movements were detected by Doppler, but only 16% of movements detected by Doppler were maternally perceived (433 of 2196). When complex movements were classified by duration, those movements lasting between 20-60 seconds were most likely (correlation greater than 0.9) to be perceived by the mother. This Doppler method has the potential to replace maternal event marking and other techniques in the recording of fetal movement.
对27名女性进行了研究，以评估母亲感知到的胎动与多普勒设备记录的胎动之间的关系。母亲感知到的胎动中有88%（492次中的433次）能被多普勒检测到，但多普勒检测到的胎动中只有16%能被母亲感知到（2196次中的433次）。当根据持续时间对复杂胎动进行分类时，持续20至60秒的胎动最有可能（相关性大于0.9）被母亲感知到。这种多普勒方法有可能取代母亲事件标记法和其他胎儿运动记录技术。
