[A non-invasive stress test for fetal movement stimulation].
A method for foetal stimulation is required for both interpretation of external CTG and assessment of foetal mobility status. All methods so far described in the literature proved to be impracticable for their invasive nature or for insufficient controllability. An approximately unitised level of stimulation is necessary for proper assessment of mobility standards, and this has been achieved by means of sound stimulation. The latter is based on a body sound transmitter coupled to a sinus generator. Sensitivity of the method is 90 per cent. Preliminary comparison between quantity of movement and birth weight of examined foetuses has provided some clues to the effect that the responsiveness to external stimuli of newborns with low birth weight had been comparatively low, which was reflected in less movement activity.
