title: Nonlinearity of the Jongkees difference equation for vestibular hypofunction.
abstract: The Jongkees formulation for vestibular paresis normalizes the difference between total left and right caloric responses to the sum of responses. When studied over the full paresis range of 0% to 100% hypofunction, the Jongkees formula is found to be a nonlinear index that does not accurately indicate the percentage of vestibular paresis. A linear paresis formula is described that more directly conveys the magnitude of relative vestibular hypofunction.
