[Study of congenital hemiplegia: value of x-ray computed tomography of the brain and of somatosensory evoked potentials].

21 cases of children with congenital hemiparesis have been studied by computerized tomography (CT) of the head and somatosensory evoked potentials (SEP). Computerized tomography is correlated with clinical features and may disclose cerebral lesions and their physiopathological mechanisms. Somatosensory evoked potentials allow a more functional approach of the handicap but are not perfectly correlated with the motor deficit. SEP are correlated with the topography of cerebral lesions showed by CT. These two investigations seem to be interesting and complementary for the exploration of congenital hemiparesis.
