Continuous measurements of gross fetal body movements were made with an ultrasonic real-time scanner for periods of 24 hours in 31 women. Fetuses made 0 to 130 gross fetal body movements per hour which accounted for 0% to 50% of the time. At 38 to 39 weeks' gestational age, fetuses demonstrated a peak in activity between 2100 and 0100 hours. The longest period of complete absence of gross fetal body movements was 75 minutes. Maternal meals and glucose concentrations did not influence gross fetal body movements.
使用超声实时扫描仪对31名孕妇进行了24小时的胎儿总体活动连续测量。胎儿每小时的总体活动为0至130次，占总时间的0%至50%。在妊娠38至39周时，胎儿在21:00至01:00之间活动最为活跃。胎儿总体活动完全停止的最长时间为75分钟。孕妇进餐和血糖浓度对胎儿总体活动没有影响。
