The Bárány tests have been depended on for years in measurement of disturbances of vestibular function. The tests have been used in examination of patients who may have no vestibular disease but who have subjective complaints, perhaps due to a structural or physiologic defect in the central pathways connected with the vestibular apparatus.
Various workers have devised modifications of the Bárány tests, each modification having a specific purpose. It has been recognized that standard caloric and rotation tests produce excessive stimulation for the measurement of finer degrees of functional defect. One practical difficulty with the Bárány tests is that the procedures require special equipment and that interpretation is difficult unless they are carried out by an examiner who is fully familiar with and frequently performs the tests.
A number of years ago I was impressed by a patient who had the clinical picture of acute labyrinthitis on the left side,
