title: Studies on fetal motor behaviour in normal and complicated pregnancies.
abstract: The possibility of studying fetal motor behaviour by ultrasound techniques has provoked research on its potential application for assessment of prenatal neurological conditions. The characteristics ('quality') of one particular movement pattern, the 'general movement', has been shown to be discriminative between uncomplicated pregnancy and major pathology of the developing central nervous system. Some recent studies have investigated whether the quality and/or the quantity of fetal movements correlated with other clinical variables during complicated pregnancies, and whether they provided prognostic information for the neurological outcome. Longitudinal research encompassing the pre- and postnatal periods was performed on uncomplicated pregnancies and on pregnancies complicated by intrauterine growth retardation, oligohydramnios (due to premature rupture of the amniotic membranes), or fetal breech position. Although the quantity of both fetal general movements and fetal breathing movements were found to be related to clinical variables of the fetal condition (such as heart rate variability, heart rate decelerations), clinical application seems limited due to large inter- and intra-individual variabilities. In contrast, the quality of fetal general movements appeared highly correlated with parameters of fetal clinical condition in individual cases and fulfilled several prerequisites for serving as a reliable diagnostic tool for prediction of the fetal condition and for assessment of the integrity of the central nervous system.
