Abstract:
The measurement of eye movement can aid in the detection and localization of vestibular pathology due to the relationship between the function of the vestibular sensory receptors in the inner ear and the eye movements produced by the vestibulo-ocular reflex (VOR). The majority of tests of vestibular function involve the measurement of horizontal eye movements produced by stimuli that activates the horizontal semicirculuar canals (hSCCs). The video head impulse test (vHIT) is a new clinical test of dynamic SCC function that uses a high-speed digital video camera embedded in light-weight goggles to record head and eye movement during passive head rotations. There are no published data concerning the examiner reliability of the vHIT. A prospective repeated measures design was used to assess test-retest reliability of the hSCC vHIT in young healthy adult participants (n=44). The vHIT was administered to each participant by each of two different examiners on two different days. A repeated measures analysis of variance was used to determine the effects of examiner, session, and hSCC on the magnitude of VOR gain (eye velocity/head velocity). The intra-class correlation coeffecient and the coefficient of repeatability were used to assess intra- and inter-examiner reliability.
