title: The effects of logon versus click on vestibular evoked myogenic potentials.
abstract: CONCLUSIONS
  Logon is superior to click to trigger larger and more consistent vestibular evoked myogenic potentials (VEMPs).
  
  
  OBJECTIVE
  To record and compare the parameters of VEMPs evoked by bone- and air-conducted logon (l-VEMPs) and click (c-VEMPs).
  
  
  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.
