The nonstress test (NST) to assess fetal wellbeing is done over the course of 30 minutes with the patient lying in the semi-Fowler position. The test relates changes in fetal heart rate to fetal movement, and uterine contractions are also recorded. The purpose of this study was to determine whether the NST is affected by maternal ambulation, so that the patient must be lying down when it is performed. We did the NST during ambulation as well as with the patient reclining. There were no differences in fetal heart rate and/or uterine activity between the 2 tests. 50% of the women preferred the ambulatory method while 25% preferred reclining and 25% expressed no preference. We conclude, that the ambulatory NST is an acceptable alternative to the conventional test with the patient reclining.
用于评估胎儿健康状况的无应激试验（NST）在患者处于半福勒卧位的情况下进行，持续30分钟。该试验将胎儿心率变化与胎儿活动相关联，同时也记录子宫收缩情况。本研究的目的是确定NST是否会受到孕妇活动的影响，因此进行该试验时患者必须躺下。我们在孕妇活动时以及患者躺卧时都进行了NST。两项试验在胎儿心率和/或子宫活动方面没有差异。50%的女性更喜欢活动时进行NST的方法，25%的女性更喜欢躺卧进行，25%的女性表示没有偏好。我们得出结论，活动时进行NST是患者躺卧进行传统试验的一种可接受的替代方法。
