Abstract

Fetal vibroacoustic stimulation was performed as a sham test and a real test in 264 patients who underwent ultrasonographic examination at the National University Hospital, Singapore. The patients were at a gestational age of 24 to 43 wks. Fetal movements were assessed by studying the fetuses with ultrasound and by asking mothers if they felt fetal movements. Real stimulation produced significantly more movements than sham stimulation (95% and 5%, respectively, p < 0.0001). The sound provoked fetal movements detected by ultrasound were felt by 77% of the mothers. The percentage of agreement was gestational-age-dependent and highest in the most mature fetuses. We conclude that maternal perception of sound provoked fetal movements seems to have a higher correlation to ultrasonically observed fetal movements than perception of spontaneous fetal movements to ultrasound observations.
