When performing the<unk> , patients are lowered quickly to a supine position (lying horizontally with the face and torso facing up) with the neck extended 30 degrees below horizontal by the clinician performing the maneuver. The<unk><unk>  and the side-lying testing position have yielded similar results. As such, the side-lying position can be used if the<unk><unk>  cannot be performed easily. Steps: The examiner looks for nystagmus (usually accompanied by vertigo). In BPPV, the nystagmus typically occurs in A or B only, and is torsional—the fast phase beating toward the lower ear. Its onset is usually delayed a few seconds, and it lasts 10–20 seconds. As the patient is returned to the upright position, transient nystagmus may occur in the opposite direction. Both nystagmus and vertigo typically decrease on repeat testing.
