title: [Computer-aided techniques for the treatment and rehabilitation of patients suffering vertigo and balance disorders].
abstract: A new computerized method is proposed for the correction and elimination of undesirable illusory sensations (dizziness), vestibulo-oculomotor (nystagmus), and vestibulo-postural (imbalance) reactions. The method allows to teach the subject about how to avoid generalization of afferent signals over the effector mechanisms in the central nervous system by developing a fixational reflex employing delayed biological feedback for the assessment of efforts being exerted (self-control of training results). Three variants of application of this technique were evaluated depending on the type of stimulation software intended to induce illusory and oculomotor reactions of a defined sensory modality (visual, vestibular or combined). The study involved 30 subjects divided into three groups. They had been taught using the visual (group 1), vestibular (group 2) or combined (group 3) methods. Each group was comprised of an approximately equal number of subjects with vestibulopathies of either peripheral or central origin. The study demonstrated that the proposed approach allows to invoke, with the use of a computer stimulation software, abnormal illusory and vestibulo-oculomotor responses and inhibit them by developing the adequate fixational reflex. Comparative analysis of the results obtained by teaching the patients with the help of the three different methods revealed the dependence of their effectiveness on the level of disturbances in the vestibular system. The visual method of correction proved to be especially efficacious for the patients with peripheral vestibulopathy, and the vestibular methods for the patients with central vestibulopathy. Patients with combined peripheral and central vestibulopathy required the choice of training modalities (either visual or vestibular) on an individual basis.
