Résumé
In an attempt to diminish the intensity of vertigo, this study was designed to reduce the imbalance between the vestibular system on the two sides. By rotating the subjects with a string-activated rotating chair in opposite direction of the dominant side, the dominant side would be inhibited and simultaneously the subordinate side would be stimulated. Eight patients with vestibular vertigo confirmed by ENG and rotatory test were subjected to a rotatory stimulus, the effect of which was evaluated by rotatory test. V [max] of the two sides of all patients were compared before the stimulus and 10, 40, and 70 minutes afterwards. The results indicate a significant difference between directional preponderance [DP] values before and after stimulation, especially at 70 minutes. The initial values of DP in 5 of 8 patients were out of the normal range and were significantly reduced to lower levels after stimulation, especially after 70 minutes when DP fell within normal limits. In two of the remaining patients, a change in direction was observed at 40 minutes, and it remained so even after 70 minutes in one of them. By minimizing the inequality between the vestibular discharge on the two sides, a reduction in vertigo intensity is expected
