MANIOBRA DIX HALLPIKE PDF

Procedure[ edit ] When performing the Dix—Hallpike test, 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. As such, the side-lying position can be used if the Dix—Hallpike cannot be performed easily. In BPPV, the nystagmus typically occurs in A or B only, and is torsional--the fast phase beating towards the lower ear. Its onset is usually delayed a few seconds, and it lasts 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.
