Dix Hallpike storage sample

from Wikipedia, the free encyclopedia

The Dix-Hallpike sample , even Dix-Hallpike maneuver is a special bearing with rotation of the head, which for the diagnosis of the benign (paroxysmal) (benign) paroxysmal positional vertigo is used.

To carry out a 30-second inspection of the eyes of the patient sitting on the examination couch is carried out in order to be able to observe any existing nystagmus (= fast, jumping eye movements). The patient's head should be hyperextended backwards ( dorsiflexed ) by about 20 degrees and turned 45 degrees to the affected side. After the patient has been informed about the following maneuver and the need to keep his eyes open, he is quickly placed in the lying position. The head should hang over the examination table. The test is positive if the patient feels vertigo after a few seconds of latency and the examiner can observe nystagmus. Both should pass ( cease ) within a minute . A positive test supports the diagnosis of benign paroxysmal positional vertigo of the posterior semicircular canal of the lower ear. After the patient is straightened up again, nystagmus may again be observed. When the maneuver is repeated on the same side, nystagmus and dizziness usually decrease (fatigue). The test should be done for both sides. The sensitivity of the maneuver is given as 88 percent

False negative results can be avoided with the use of Frenzel glasses , which help to identify nystagmus.
