[Monitoring fetal movements using the Doppler-Fizeau effect with a new apparatus: the Tococinon].

We introduce the Tococinon, which is an apparatus using the Doppler-Fizeau effect. Its purpose is to record fetal movements. The method carries good correlation with ultrasonographic observations of fetal movements. It is more accurate than the patient's own impressions, and can be used from the end of the first trimester until term. The Tococinon makes it possible for the mother to watch her own baby's behaviour and to screen for abnormalities in it. Its development makes it possible for us to foresee other studies on different types of movement and to attempt to correlate these with some pathological states.
