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. [3] The Dix–Hallpike and the side-lying testing position have yielded similar results. As such, the side ...
Vestibular reflexes can also be examined using body tilt experiments. Patients with vestibular disorders may go through the Dix-Hallpike maneuver, in which the patient is seated with legs extended and rotates the head 45 degrees. The patient is then asked to lie down on the table and checked for nystagmus, or uncontrollable eye movements ...

Elicitation of extreme vertigo upon lateral movement of a patient's head when lying in a supine position Döhle bodies: Karl Gottfried Paul Döhle: pathology: various including trauma and neoplasm
The patient begins in an upright sitting posture, with the legs fully extended and the head rotated 45 degrees toward the side in the same direction that gives a positive Dix–Hallpike test. Then the patient is quickly lowered into a supine position (on the back), with the head held approximately in a 30-degree neck extension (Dix-Hallpike ...
The condition is diagnosed by the person's history, and by performing the Dix–Hallpike test or the roll test, or both. [24] [25] The patient can also be asked to induce vertigo by performing a movement that the patient knows to induce vertigo. The eyes of the patient can then easily be observed for which kind (horizontal, vertical, or ...
BPPV may affect anterior, posterior or horizontal vestibular canals. The posterior canal was reported in the literature as the most commonly affected canal, occurring in 80% of patients diagnosed with BPPV. Several positional tests such as Dix-Hallpike, supine roll test, and head shaking nystagmus test may indicate which canal is affected by ...
Before taking the test, the patient may be instructed to fast for a period before the test will take place and to stop taking any medications. On the day of the tilt table test, an intravenous line may be placed in case the patient needs to be given medications quickly; however, this may influence the results of the test and may only be indicated in particular circumstances.
