To determine the influence of diurnal variation in maternal movements (MM) on fetal heart rate (FHR) accelerations, 24‐hour maternal heart rates (MHR), MM and FHR recordings were made simultaneously on nine healthy pregnant women at 36–39 weeks of gestation. Correlations between the diurnal variations in maternal factors and FHR parameters; that is, baseline FHR, amplitude, duration and hourly percentage of time spent in accelerations, were examined. Only a few cases showed a significant correlation between acceleration parameters and the diurnal variation of MHR or MM, while most cases indicated a high correlation between the diurnal variation in baseline FHR and that of maternal factors. In conclusion, the occurrence and form of accelerations might be independent of maternal activity.
