Abstract
A caloric testing technique and apparatus for evaluating vestibular ear disorders by independently stimulating the left and right lateral canal receptor organs, using heated and cold air, and measuring the responses in order to obtain an indication of disordered vestibular function. Timed irrigation periods are employed, the periods being adjustable so as to control the magnitudes of the caloric stimulations, and the measurements of responses are made by the electrical recording of eye movements for accurate measurement of nystagmic response intensity.
