The Dix-Hallpike test is a diagnostic manoeuvre used to identify benign paroxysmal positional vertigo (BPPV). The Epley manoeuvre is used to treat BPPV (usually of the posterior canal) once it has been diagnosed by the previously mentioned Dix-Hallpike test.
What does a positive hallpike test mean?
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.
What does hallpike Dix maneuver test for?
Doctors use the Dix-Hallpike test (sometimes called the Dix-Hallpike maneuver) to check for a common type of vertigo called benign paroxysmal positional vertigo, or BPPV. Vertigo is the sudden feeling that you or your surroundings are spinning.
Which side is positive Dix-Hallpike?
Positive: “down” side produces nystagmus and is the side causing the positional vertigo. If the right side is being tested (in the “down” position), the eye will rotate in a counterclockwise manner during the rapid phase of nystagmus, with a minor up-beating vertical (toward the forehead) component.
What if Dix-Hallpike is negative?
Dix-Hallpike maneuver negative If your Dix-Hallpike test is negative, it’s possible that there is another cause for your vertigo symptoms, such as: migraine. ear infection. inflammation of the nerves inside your ear (called vestibular neuritis)

What is a positive Epley maneuver?
Dix-Hallpike maneuver positive The Epley maneuver consists of a series of slow movements of your head and neck. These movements can dislodge canaliths and move them into a part of your ear where they’ll stop triggering vertigo.
Is Dix-Hallpike positive without nystagmus?
Caovilla & Ganança31 state that the possible results from the Dix-Hallpike test in BPPV with and without nystagmus are: positive objective, when there is nystagmus associated with vertigo, positive subjective when there is only vertigo and negative in the absence of nystagmus and vertigo.
How accurate is Dix-Hallpike?
The ability of the Dix-Hallpike maneuver to correctly diagnose people with BPPV is anywhere from 48 to 88 percent. Obviously, this is a huge gap. Medical literature suggests that if a specialist or someone deeply familiar with the test performs it, you’ll more likely receive an accurate result.
