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.

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.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
