When performing the Dix-Hallpike test, make sure to warn the patient in advance of each step, so that they know what to expect: 1. Ask the patient to sit upright on the examination couch. 2. Adjust the patient’s position so that when supine, their head will hang over the edge of the bed, allowing for head extension below the horizontal plane. 3. Po...
When performing the Epley manoeuvre, each position should be maintained until full resolution of symptoms and nystagmus has been achieved for at least 30 seconds: 1. The Epley manoeuvre typically follows on from a positive Dix-Hallpike test, so we will assume the patient is still positioned lying flat, with the head hanging over the end of the bed,...

Apr 11, 2020 · Dix-Hallpike test: gold-standard for diagnosis; positive test shows latency, vertigo, rotatory and vertical nystagmus; contraindicated in neck/back pathology. Management: self-limiting within 6 months; avoid provoking positions, counsel on recurrence risk; vestibular rehabilitation (Epley manoeuvre, Semont manoeuvre, Brandt-Daroff exercises).
A positive test is indicated by patient report of a reproduction of vertigo and clinician observation of nystagmus (involuntary eye movement). For some patients, this maneuver may be contraindicated, and a modification may be needed that also targets the posterior semicircular canal.
Feb 3, 2013 · The test must be performed quickly to ensure adequate displacement of the endolymp and otoconia, which helps to provoke the expected symptoms. A positive result, indicating canalithiasis of the posterior canal, occurs when the test induces vertigo and short-duration nystagmus.
