Abstract

The purpose of this work was to develop a compact, noninvasive and objective tool for foetal movement monitoring and classification. Four tocodynamometers were used as movement transducers and their output signals processed by a minicomputer on which a microprocessor real time compatible algorithm was developed. The algorithm was based on time domain analysis where the parameters, such as averaging intervals and threshold levels were optimised in a trial and error procedure to minimise undetected foetal movements and false detections on a set of nine pregnant women. The detection score was 92·2 per cent when short foetal movements were ignored.
