High frequency head rotation test has been suggested as a method of assessing the vestibuloocular reflex. The purpose of this study was to investigate the test-retest variability of this test in normal subjects for the future clinical application. Ten asymptomatic, healthy subjects were tested 3 times repeatedly over the frequency range 1.0 to 6 Hz using Vorteq system (Micromedical Technologies). Results indicated that means of gain, phase and asymmetry were stable from 1 Hz up to 6 Hz, but standard deviations increased as the frequency increased, and test-retest variability increased over 3 Hz. These findings provide a motivation for the future studies to investigate the factors which can affect the test results and to develop a new test method.
