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 (1-VEMPs) and click (c-VEMPs). Subjects and methods. Air- and bone- conducted 1-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 1-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 1-VEMPs with respect to c- VEMPs.
