Different aspects of vestibular nystagmus (elicited during and after constant velocity whole body rotation) were compared to the magnitude of curvature. Stepwise regression analysis revealed that the durations of per and postrotary nystagmus were the most significant predictors of curvature, and the time constant was the second most significant predictor. Both time constant and duration of nystagmus were found to be inversely related to curvature. A re-test of eleven subjects six months later revealed no significant changes in vestibular processing, inspite of an increase in the magnitude of curvature. It is possible that in these subjects, dysfunction in vestibular processing preceeded the occurrance of the scoliotic curve.en-USPLEASE NOTE: Boston University Libraries did not receive an Authorization To Manage form for this thesis or dissertation.
