“…These changes suggest a better fetal oxygen supply in the left lateral than in the supine maternal position. This is basically in accordance with previous findings (1–4). A partial but important difference is that Cito et al (4) noticed no change of fetal heart rate by altering maternal position.…”

“…The relationship of the maternal body position to fetal well‐being during labor has been understood for many decades (1). In addition, maternal body position can influence fetal well‐being without uterine contractions – results of non‐stress tests (NSTs) are most unfavorable when mothers lie on their back (2–4).…”

“…The brochure, which included a fetal movement chart (a kick chart), was provided at the ultrasound screening assessment in gestational week 17-19, which 98% of the women attend. The brochure covered information on: expected normal fetal activity [31]; differences in perception according to different fetal movements [31], maternal position [32], the inter- and intraindividual variation between fetuses [9], maternal weight [27], and smoking [33]; interpretation of variation of fetal activity; instructions on how to use the kick chart; and when to contact health professionals if experiencing DFM [11]. …”

Implementation of uniform information on fetal movement in a Norwegian population reduced delayed reporting of decreased fetal movement and stillbirths in primiparous women - a clinical quality improvement

BackgroundDelayed maternal reporting of decreased fetal movement (DFM) is associated with adverse pregnancy outcomes. Inconsistent information on fetal activity to women during the antenatal period may result in delayed reporting of DFM. We aimed to evaluate an intervention of implementation of uniform information on fetal activity to women during the antenatal period.MethodsIn a prospective before-and-after study, singleton women presenting DFM in the third trimester across 14 hospitals in Norway were registered. Outcome measures were maternal behavior regarding reporting of DFM, concerns and stillbirth. In addition, cross-sectional studies of all women giving birth were undertaken to assess maternal concerns about fetal activity, and population-based data were obtained from the Medical Birth Registry Norway.ResultsPre- and post-intervention cohorts included 19 407 and 46 143 births with 1 215 and 3 038 women with DFM respectively. Among primiparous women with DFM, a reduction in delayed reporting of DFM (≥48 hrs) OR 0.61 (95% CI 0.47-0.81) and stillbirths OR 0.36 (95% CI 0.19-0.69) was shown in the post-intervention period. No difference was shown in rates of consultations for DFM or maternal concerns. Stillbirth rates and maternal behavior among women who were of non-Western origin, smokers, overweight or >34 years old were unchanged.ConclusionsUniform information on fetal activity provided to pregnant women was associated with a reduction in the number of primiparous women who delayed reporting of DFM and a reduction of the stillbirth rates for primiparous women reporting DFM. The information did not appear to increase maternal concerns or rate of consultation. Due to different imperfections in different clinical settings, further studies in other populations replicating these findings are required.

“…The degree to which this reflects normative fetal behavior when women are standing, engaged in routine activities over the course of a day, or at night, is unknown. A small number of older studies recorded fetal heart rate during maternal exercise on stationary bicycles (Webb, Wolfe, & McGrath, 1994) and there have been several comparisons of non-stress test results in different maternal positions(Cito et al, 2005). One of the few studies to examine the effects of proprioceptive cues on the fetus by passively moving pregnant women in a rocking chair found that a rocking motion elicited fetal heart rate responsivity but lateral gliding did not (Lecaneut & Jacquet, 2002).…”

Among the earliest volumes of this Monograph series was a report by Lester Sontag and colleagues, of the esteemed Fels Institute, on the heart rate of the human fetus as an expression of the developing nervous system. Here, some 75 years later, we commemorate this work and provide historical and contemporary context on knowledge regarding fetal development, as well as results from our own research. These are based on synchronized monitoring of maternal and fetal parameters assessed between 24 and 36 weeks gestation on 740 maternal-fetal pairs compiled from eight separate longitudinal studies, which commenced in the early 1990s. Data include maternal heart rate, respiratory sinus arrhythmia, and electrodermal activity and fetal heart rate, motor activity, and their integration. Hierarchical linear modeling of developmental trajectories reveals that the fetus develops in predictable ways consistent with advancing parasympathetic regulation. Findings also include: within-fetus stability (i.e., preservation of rank ordering over time) for heart rate, motor, and coupling measures; a transitional period of decelerating development near 30 weeks gestation; sex differences in fetal heart rate measures but not in most fetal motor activity measures; modest correspondence in fetal neurodevelopment among siblings as compared to unrelated fetuses; and deviations from normative fetal development in fetuses affected by intrauterine growth restriction and other conditions. Maternal parameters also change during this period of gestation and there is evidence that fetal sex and individual variation in fetal neurobehavior influence maternal physiological processes and the local intrauterine context. Results are discussed within the framework of neuromaturation, the emergence of individual differences, and the bidirectional nature of the maternal-fetal relationship. We pose a number of open questions for future research. Although the human fetus remains just out of reach, new technologies portend an era of accelerated discovery of the earliest period of development.

Maternal position during non‐stress test and fetal heart rate patterns

Abstract: Non-stress test in sitting position or during walking should be encouraged because fetal reactivity is more quickly observed.
