[Computerized methods for therapy and rehabilitation of patients suffering dizziness and balance disorder].
A new computerized method is proposed for correction and inhibition of unfavorable illusory (vertigo), vestibular-oculomotor (nystagmus), and vestibular-postural (balance) responses. This method allows to teach the subject to block generalization of an afferent signal to effector mechanisms of the central nervous system by developing a fixational reflex, utilizing a delayed biofeedback. Three variant ofthis method were employed, depending on the kind of stimulation programs aimed at inducing abnormal responses of a certain sensory modality (visual, vestibular or combined). The study involved 36 subjects divided into 3 equal groups one of which had been taught by a visual or vestibular technique, and the last one by a combined. Each group included approximately equal numbers of subjects with vestibulopathies of an organic (peripheral or central) or psychogenic origin. It was demonstrated that the method proposed allows, with the help of computerized stimulation programs, to provoce abnormal illusory and vestibular-optooculomotor responses in the subject, and inhibit them with the help of development of a fixational reflex. Patients were taught using three various variants of the method. A subsequent comparative analysis of results obtained has shown dependence of their effectiveness on the level of disturbance in the vestibular system: the visual variant of correction was the most effective for subjects with peripheral vestibulopathia; for subjects with central vestibulopathia, the vestibular variant was more effective; the combined variant of correction was the most effective for subjects with psychogenic vestibulopathia.
