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 ide 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 mal of the two sides of all patients were compared before the stimulus and to, 40, and 70 minutes afterwards. The result indicate a significant difference between directional preponderance COP) 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 timulation, especially after 70 minutes when DP fell within normal limits. In two of the remaining patient , a change in direction was observed at 40 minutes, and it remained '0 even after 7 minute in one of them. By minimizing the inequality between the vestibular discharge on the two sides, a reduction in vertigo intensity is expected
