Calculation of the circularvection times in a population with vestibular pathology. Influence of visual stimulus.
OBJECTIVE
[corrected] To describe the results obtained for circularvection times (tCV) in a study of the phenomenon of visual-vestibular interaction for a population with vestibular pathology and to analyze differences in its calculation among patients reporting a worsening of their symptoms with visual stimuli.


METHODS
A detailed case history was taken for all patients, followed by a sensory organization test using computerized dynamic posturography and the calculation of their tCV.


RESULTS
The mean tCV results were: tCV2= 6.32+/-3.17 s; tCV3=6.57+/-3.68 s; tCVr=6.27+/-6.02 s. Significant differences were obtained in tCV2 (P=.046) and tCVr (P=.023).


CONCLUSIONS
tCV is a diagnostic test using simple tools that can help differentiate patients in whom the visual stimulus is influenced.
