The Epley maneuver is also know as the particle repositioning maneuver. It is used to treat a particular cause of dizziness called Benign Positional Vertigo. This type of vertigo is thought to be caused by crystals in the inner ear which become dislodged and float in the fluid in the inner ear, disrupting the normal balance mechanism. The Epley maneuver works by allowing the free floating particles to be relocated to the proper position by gravity and head positioning, thereby relieving the patient of the bothersome vertigo. It is often performed by a physician, physical therapist or audiologist after the dizziness has been confirmed. it can also be performed by the patient at home with the appropriate instructions. This maneuver does not help other causes of vertigo.
