In VEMP testing, which muscle is typically monitored for oVEMP?

Explanation:
oVEMP measures the vestibulo-ocular reflex by recording from extraocular muscles. The inferior oblique muscle, located beneath the eye, is the primary muscle monitored because it reliably reflects utricular-driven vestibulo-ocular activity when stimuli such as sound or vibration are used. Electrodes are placed under the eye to capture potentials from these muscles, which distinguishes oVEMP from cVEMP that uses neck muscles like the sternocleidomastoid. So the monitored muscle for oVEMP is the inferior oblique / extraocular muscles beneath the eyes.
