The hair cells are mechanically pushed by the resistance of the endolymph, opening mechanically gated ion channels that trigger an action potential indicating rotational movement.
Turn recording back on. A positive test is indicated by patient report of a reproduction of vertigo and clinician observation of nystagmus involuntary eye movement.
The test results can also be affected by the speed the maneuver is done in and the plane the occiput is in.
