[Vertical vestibuloocular reflexes in affection of central parts of vestibular system (communication III)].
Vertical vestibuloocular reflexes (VVOR) were examined in 45 patients with multiple sclerosis. It is proposed to study VVOR basing on stimulation of the vertical semicircular labirynthine canals with active sagittal nodding of the head. Central lesion of the vestibular system is characterized by VVOR hyperreactivity, total failure of VVOR suppression by glance, two types of VVOR domination (typical--up and atypical--down), interocular asymmetry (dissociated nystagmus).
