Forty pregnant women participated in a study to compare subjective with ultrasound assessments of fetal movements. A real-time ultrasound scanner was used. Movements were recorded for 45 minutes in all cases. There was a significant positive correlation between the number of movements recorded by the two methods, but the 95% confidence limits were wide and no correlation was found in those patients who recorded fewer than 20 movements in the study period. Thus "false-positive" information may be obtained from purely subjective data, and in patients reporting low "kick counts" fetal activity should be assessed from real-time ultrasound recordings.
40名孕妇参与了一项研究，以比较胎儿运动的主观评估与超声评估。使用了实时超声扫描仪。所有病例均记录45分钟的胎动情况。两种方法记录的胎动次数之间存在显著正相关，但95%置信区间较宽，且在研究期间胎动少于20次的患者中未发现相关性。因此，可能会从纯主观数据中获得“假阳性”信息，对于报告“踢腿计数”较低的患者，应通过实时超声记录来评估胎儿活动情况。
