Pregnancy Clinical Trial
Official title:
Qualitative and Quantitative Study of Fetal Movements Using Multichannel Ultrasound Pulsed Doppler in Normal and Pathologic Pregnancy
To enable an investigation of fetal movements, the researchers have developed a multichannel
ultrasound pulsed Doppler called ACTIFOETUS. This new fetal monitor includes three
transducers of four sensors which are placed on three different zones of the mother's
abdomen. One of the transducers is aimed at the fetal heart, another at the lower limbs and
one transducer at the thorax and the fetal upper limbs to detect heart and body movements.
The signals are analysed and processed by software which computes a number of parameters
describing the movements.
Ninety pregnant women from 28 weeks gestation will be monitored over a 40 minute period
every month or every 2 weeks in case of pathological pregnancy. The final purpose will be to
develop a system of home monitoring as an indicator of fetal well-being.
