[Synchronous registration of vestibulospinal and vestibulo-ocular reflexes in rotatory stimulation]

A comparative study of vestibulo-spinal and vestibulo-ocular reactions is presented in normal subjects and in patients with different vestibular lesions. Four our investigations the rotatory chair was prepared with a special equipment for the "Vertical Drawing Test" to achieve the simultaneous recording of the nystagmus and laterotorsion reactions. Analyses of the two reflexes demonstrated a rare independence between the vestibulo-ocular and vestibulo-spinal reactions despite a common stimulus. Further studies supplying additional information laterotorsion to nystagmus, may be helpful in the analysis of balance. Variations were found in the patterns of behaviour in different groups of vestibular disturbances.
