| Abstract: | A new computerized method was developed for correcting and eliminating adverse illusory (vertigo), vestibulo-opto-oculomotor (nystagmus), and vestibulo-postural (balance) reactions allowing subjects to be trained to block the generalization of an afferent signal to the effector mechanisms of the CNS by acquisition of a fixation reflex using biological feedback. Two versions of the model were used, with the aims of inducing anomalous reactions of a defined sensory modality (visual or vestibular). A total of 24 patients with peripheral and central vestibulopathies were divided into two groups, one of which was trained visually, while the other was trained using a vestibular approach. The method allows anomalous illusory and vestibulo-opto-oculomotor reactions to be produced in the subjects and for these to be inhibited by acquisition of a fixation reflex. The visual correction method was the most effective for patients with peripheral vestibulopathy, while the vestibular method was the most effective for those with central vestibulopathy. |
