Epley Maneuver (Canalith Repositioning) for Benign Positional Vertigo

Benign paroxysmal positional vertigo (BPPV) is one of the most common causes of vertigo, and is thought to be caused by free-floating debris primarily in the posterior semicircular canal. The condition is usually brought on by a rapid change in head position, and diagnosis can be confirmed by a positive Dix-Hallpike test (DHT). The Epley maneuver was invented as a way to move the ear debris out of the semicircular canal, and involves a series of four sequential movements.
