Epley maneuver

The Epley maneuver or repositioning maneuver is a maneuver used by medical professionals to treat one common cause of vertigo, benign paroxysmal positional vertigo (BPPV) of the posterior or anterior canals of the ear. 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. The maneuver was developed by the physician, John M. Epley, and was first described in 1980.

A version of the maneuver called the "modified" Epley does not include vibrations of the mastoid process originally indicated by Epley, as the vibration procedures have been proven ineffective. The modified procedure has become that now described generally as the Epley maneuver.
