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
