[Diurnal variation of active movements: an indication of fetal hypotrophy?]
1Centre de Gynécologie et Obstétrique, Centre hospitalier régional et universitaire, Amiens.
In a prospective study of 36 pregnancies, the authors made use of the mother's counting of active movements in order to evaluate the correlation between daytime fluctuations in active movements and fetal hypotrophy. With a threshold peak mean evening motor activity no more than 20 p. cent greater than in the morning throughout the period counted, daytime variations were found to have optimal diagnostic capacity for hypotrophy. During the last week preceding delivery, a threshold mean peak evening active movements no more than 35 p. cent greater than in the morning yielded optimum diagnosis of fetal hypotrophy. Furthermore, there was a correlation between daytime fluctuations in active movements and the findings of fetal ultrasound biometry and utero-umbilical flow velocimetry.
