In VEMP testing, a loud stimulus (90-95dB nHL) is often required to elicit the desired
response. VEMP testing contraindications
1
include:
• Presence of tinnitus, hyperacusis or other sensitivity to loud sounds
• Conductive hearing loss caused by middle ear effusion, perforated eardrum or
otosclerosis which may decrease the intensity of the stimulus such that the
response is significantly reduced or absent
Recording cVEMP requires the patient to turn their head to the right and left of center to
a minimum of a 45-degree angle such as to contract the sternocleidomastoid (SCM)
muscle and therefore the contraindications include (in addition to the above mentioned
for VEMP testing):
• Cervical spine, neck issues or pain that prohibit head turn
• Cervical spine, neck issues or pain that prohibit the patient from performing and
maintaining the contraction the SCM muscle for the duration of the test
Recording oVEMP requires the patient to gaze upward and therefore the
contraindications include (in addition to the above mentioned for VEMP testing):
• absence or damage to the eyes or eye musculature
• inability to gaze upward for the duration of the test
If there is any doubt, then a medical opinion should be sought prior to testing. In all
cases the test should be terminated if any signs of discomfort are displayed.
