with the light bar method, as compared with OKN-RVT. We have shown furthermore that OKN-RVT testing, while better than OKN-ENG, has a poor sensitivity. Therefore OKN-RVT alone will not properly identify all patients with central vestibular pathology and should be used in a test battery with other tests of central vestibular function. In conclusion, a proper understanding of the information provided by these vestibular tests is needed for their correct use in patient treatment. We thank Dr Linda Bartoshuk and Dr Jim Jekel for their statistical analyses of the data presented here.
