Benign Paroxysmal Positional Vertigo (BPPV) is the most common peripheral vestibular system disorder. Prevalence in the geriatric population is estimated at ~10%.1,2 The condition is typically caused by displaced otoconia, and potentially underlying otolithic membrane, which are free-floating in the semicircular canal (canalithiasis).3,4

The disorder is of strong interest to physical therapists because the condition is diagnosed (Dix-Hallpike) and treated with physical head positioning maneuvers. Medication is typically not helpful and surgical intervention (canal plugging) is only pursued in refractory cases.
