[Characterization of active fetal movements in early pregnancy using ultrasound (time-motion technic)].
In 82 pregnancies between 9 and 14 weeks of amenorrhea, 120 registrations of active movements of the embryo were recorded by the ultrasonic time motion technique. Four types of early motility could be observed: Ia = single convulsions of the body, Ib = series of body convulsions, II = rapid movements of the extremities, III = combined complexe movements. The frequency and complexity of the movements increased with progressing gestational age.
