The total fetal movement activity was determined in 111 pregnant patients from 24 weeks to 42 weeks by simultaneous real-time ultrasonography and tocodynamometry. A comparison of the methods of investigation showed that tocodynamometry only detects 37% of all fetal movements with or without movements of the extremities. Movements of the extremities were only recorded in 14% of the cases. A total of only 25% of all fetal movements showed "spikes" in the tocogram. Of all the recorded spikes only 56% corresponded to a fetal movement, whereas 44% of the spikes in the tocogram were false-positive. These data demonstrate that routine clinical cardiotocography has a limited value only in the monitoring of fetal movement activity.
通过实时超声检查和宫缩图测定法，对111名孕周在24至42周的孕妇进行了胎儿总活动量的测定。对检查方法的比较显示，宫缩图测定法仅能检测出所有胎动（无论有无肢体活动）的37%。仅在14%的病例中记录到了肢体活动。在所有胎动中，总共只有25%在宫缩图上显示为“尖峰”。在所有记录到的尖峰中，只有56%与胎动相对应，而宫缩图上44%的尖峰为假阳性。这些数据表明，常规临床胎心宫缩图监测在胎儿活动监测方面的价值有限。
