Abstract

Trapezoid Rotation Tests using the Contraves computerized rotary chair system were performed in 60 normal subjects and 213 patients with peripheral vestibular disorder. In normal subjects, directional preponderance was not observed. The so-called 'response decline phenomenon' by repeating the tests was not detected and the test results showed good reproducibility. On the other hand, the test results of patients were variable, in close relationship with the state of vertigo, and reflected patient's labyrinthine pathology so accurately that the inspection of the treatment course was possible by this testing system.
