Epley maneuver

The Epley maneuver or repositioning maneuver is a maneuver used to treat benign paroxysmal positional vertigo (BPPV) of the posterior or anterior canals. It works by allowing free floating particles from the affected semicircular canal to be relocated, using gravity, back into the utricle, where they can no longer stimulate the cupula, therefore relieving the patient of bothersome vertigo. It is often performed by a medical doctor, occupational therapist, audiologist, Osteopath, chiropractor, or physical therapist, after confirmation of a diagnosis of BPPV using the Dix-Hallpike test and has a reported success rate of between 90–95%. This maneuver was developed by Dr. John Epley and first described in 1980. Physiotherapists, Osteopaths and some chiropractors now use a version of the maneuver called the "modified" Epley that does not include vibrations of the mastoid process originally indicated by Epley, as they have since been shown not to improve the efficacy of the treatment.
