The effects of logon versus click on vestibular evoked myogenic potentials

Abstract

Conclusion. Logon is superior to click to trigger larger and more consistent vestibular evoked myogenic potentials (VEMPs). Objectives. To record and compare the parameters of VEMPs evoked by bone- and air-conducted logon (l-VEMPs) and click (c-VEMPs). Subjects and methods. Air- and bone-conducted l-VEMPs and c-VEMPs were recorded in 28 normal ears with an Amplaid MK12 (Amplaid, Milan) equipment. Results. VEMPs response rate was 100% with both air-conducted logon and click, while l-VEMPs showed a higher response rate (79%) in comparison with c-VEMPs (21%) with bone-conducted stimuli. A significant (p<0.05) increase of P1, N1 and P1-N1 amplitude and augmented P1 and N1 latencies were noticed in l-VEMPs with respect to c-VEMPs.
