title: The evolution of the vestibular apparatus according to the age of the infant.
abstract: In 56 full-tem A.G.A. infants and in 27 infants of a minimal age of 15 days with a neurological "risk" (full-term small for gestational age, S.G.A.), the nystagmic response to vestibular stimulation (rotatory and torsion swing test) was examined. A delay in the appearance of a response to the labyrinthic stimulus and a persistence of the prevalence of the slow phase of the nystagmus appeared clearly higher in the "risk" infants. The statistical difference of the response between the two groups was highly significant. This allowed us to conclude that the vestibular test appears to the one of the most useful in evaluating the sensorial maturation of S.G.A. infants.
