Abstract
Introduction: The concurrent literature reflects wide variations in the use of response filter for acquiring ocular vestibular-evoked myogenic potentials (oVEMPs). However, there is dearth of published reports on the effects of changes in response filter on oVEMP. Therefore, the present study aimed at evaluating the effect of variations in the response filter on oVEMP and identifying the optimum filter set for its clinical recording. Methods: Contralateral oVEMPs were elicited in response to 500 Hz tone bursts from thirty healthy individuals. The low-pass filters used were 500, 700, 1000, 1500, 2000, and 3000 Hz, and the high-pass filters used were 1, 10, and 30 Hz, in all possible combinations. Results: There was a significant reduction in n1- and p1-latencies with increase in high-pass and low-pass filters (P
