Benign paroxysmal positional vertigo (BPPV), which was first identified by Barany, is the most common peripheral vestibular pathologic condition. BPPV is defined as an abnormal sensation of movement, usually evoked by sudden head movements.The specific cause of BPPV is still unknown, however it may be associated with various disorders of the inner ear or head trauma(1)

Otoliths called autoconial debris that pass from the utricular macula to the semicircular canal are responsible for the pathogenesis of BPPV. This can happen in two different ways: canalolithiasis and cupulolithiasis. Canalolithiasis occurs when otoliths enter the canal from the non-bulbous end and move freely in the canal. Cupulolithiasis occurs by the adhesion of otoliths in the cupule of the crista ampullaris. The most commonly involved canal is the posterior semicircular canal and the form of posterior canal canalolithiasis is mostly observed. Epley maneuver is done in posterior canal Benign paroxysmal positional vertigo to reposition these otolith into original position

The diagnosis of BPPV is performed by using the Dix---Hallpike Maneuver The success rate of Epley Manuever is ranged between 75%---89%Epley maneuver In patients with posterior canal canalolithiasis may increase the success of Epley Maneuver. In this study, the results of Berg Balance Scale (BBS) and Dizziness Handicap Index (DHI) and VEMP are evaluated in patients who underwent head-shaking maneuver before Epley Maneuver and who underwent Epley Maneuver without head-shaking maneuver before treatment and at the 1st week after treatment.(1)
