Diagnosis of posterior semicircular canal benign paroxysmal positional vertigo
Abstract
Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo. It is a mechanical disorder of the inner ear, perceived as a sudden spinning sensation (vertigo) when the position of the head changes with respect to gravity. BPPV has a considerable impact on patients’ quality of life. It most commonly affects the posterior semicircular canal and is clinically detected with the Dix-Hallpike maneuver. Physiotherapists should diagnose posterior semicircular canal BPPV when vertigo is associated with torsional upbeating nystagmus towards the affected ear, caused by the maneuver.
