ObjectivePrimary care physicians need good screening tests of the vestibular system to help them determine whether patients who complain of dizziness should be evaluated for vestibular disorders. The goal of this study was to determine whether current, widely used screening tests of the vestibular system predict subsequent performance on objective diagnostic tests of the vestibular system (ENG).MethodsOf 300 subjects who were recruited from the waiting room of a primary care clinic and were screened there, 69 subjects subsequently volunteered for ENGs in the otolaryngology department. The screening study included age, history of vertigo, head impulse tests, Dix-Hallpike maneuvers, and the Clinical Test of Sensory Integration and Balance with the head still and the head pitching at 0.33 Hz. The ENG included Dix-Hallpike maneuvers, vestibular-evoked myogenic potentials, bithermal water caloric tests, and low-frequency sinusoids in the rotatory chair in darkness.ResultsThe scores on the screening were related to the total ENG, but odds ratios were not significant for some variables, probably because of the small sample size.ConclusionsA larger sample may have yielded stronger results, but in general the high odds ratios suggest a relation between the ENG score and Dix-Hallpike responses and between the ENG scores and some Clinical Test of Sensory Integration and Balance responses.
