Position
For the
cVEMP
measurement, the patient’s position is very important because it directly affects the measurement quality.
Indeed, to correctly collect data, the
s
ternocleidomastoid muscle must be contracted enough. The best way for that is to lie
down the patient and ask him to keep his head elevated in the opposite direction of the stimulation.
To make measurement on both ears easier, it is recommended to equip one ear at a time because the meas-
urement position is hard to hold when the electrodes and clips are on both sides.
