Patient, observer and instrumental methods for recording fetal movements are described. Significant correlations between both patient and observer, and patient and instrumental fetal movement counts, were found. Significant diurnal, daily and weekly variation in fetal movement counts occurred which need to be considered in the interpretation of the frequency of fetal movements as an indication of fetal welfare.
描述了记录胎动的患者、观察者和仪器方法。发现患者与观察者之间以及患者与仪器胎动计数之间存在显著相关性。胎动计数存在显著的昼夜、每日和每周变化，在将胎动频率解释为胎儿健康指标时需要考虑这些变化。
