Benign paroxysmal positional vertigo (BPPV) is the most common cause of peripheral vertigo. [2] It can be characterized by three main symptoms: positional onset, spinning dizziness and short-lived symptoms. The primary diagnostic maneuver is the Dix-Hallpike which elicits the cardinal sign associated with BPPV, rotatory nystagmus.

A positive test is indicated by the patient report of a reproduction of vertigo and clinician observation of nystagmus. Both the Dix–Hallpike and the side-lying testing position have yielded similar results, and as such the side-lying position can be used if the Dix–Hallpike cannot be performed easily. [26]
The maneuver works by allowing free-floating particles, displaced otoconia, from the affected semicircular canal to be relocated by using gravity, back into the utricle, where they can no longer stimulate the cupula, therefore relieving the patient of bothersome vertigo. [2] [3] The maneuver was developed by the physician John M. Epley, and was ...

The otoconia floats freely in the inner ear fluid, causing disorientation and vertigo. [1] The disorder can be tested for using a nystagmus test, such as the Dix-Hallpike maneuver. This disorder can disrupt the ...

[9] Benign vertigo episodes generally last less than one minute. [2] The Dix-Hallpike test typically produces a period of rapid eye movements known as nystagmus in this condition. [1]
