A study of fetal activity was undertaken as the first step in a series of physiologic fetal movement studies. A simple, safe, noninvasive, clinically applicable method for studying fetal movement with a tocodynamometer is described. Four basic types of fetal movement have been seen and defined in terms of their durations, recorded patterns, and descriptive terminologies for identifying each movement.
作为一系列胎儿生理活动研究的第一步，我们进行了一项胎儿活动研究。本文描述了一种使用宫缩压力计研究胎儿活动的简单、安全、无创且临床适用的方法。我们观察到了四种基本类型的胎儿活动，并根据其持续时间、记录模式以及用于识别每种活动的描述性术语对其进行了定义。
