Conclusions: cVEMPs evoked by vibration are often, but not exclusively, inhibitory in nature. Excitatory responses may be evoked when the direction of initial tap stimulation is reversed.  ...  While commonly evoked by air-conducted (AC) sound, interest is growing in cVEMPs evoked by vibration, however little is known about vibration-cVEMP properties.  ...  Results: The same electrical stimuli evoked different VOR-responses.  ...
