| Outline of Final Research Achievements |
We have been developing a system of fetal movement acceleration measurement (FMAM). This system consists of two channels of fetal and maternal movements. This study examined whether the FMAM system is useful to see maternal sleep disturbances and influences of fetal movement during a pregnant woman’s sleep on maternal sleep.
The subjects were eighteen healthy pregnant women at 24-36 gestational weeks. We recorded fetal and maternal movement signals simultaneously.At the results,maternal time in bed, and maternal waking time were similar to those of our previous polysomnographic studies. The number of synchronized fetal-maternal movements corresponded to that of maternal micro-arousals.This study suggest that the FMAM system is useful to see a pregnant woman’s sleep disturbance, especially relationships with her fetus. Further studies of fetal-maternal synchronization from late pregnancy to early postpartum are needed to investigate postpartum depression state.
