Positional vertigo Vertigo produced by changes in the head position relative to gravity Benign paroxysmal positional vertigo (BPPV) A disorder of the inner ear characterized by repeated episodes of positional vertigo. Posterior canal BPPV A form of BPPV in which dislodged inner ear particles in the posterior semicircular canal abnormally influence the balance system producing the vertigo, most commonly diagnosed with the Dix-Hallpike test. Lateral canal BPPV A form of BPPV in which dislodged inner ear particles in the lateral semicircular canal abnormally influence the balance system producing the vertigo, most commonly diagnosed by the supine roll test. Canalithiasis A theory for the pathogenesis of BPPV that proposes that there are free-floating particles (otoconia) that have moved from the utricle and collect near the cupula of the affected canal, causing forces in the canal leading to abnormal stimulation of the vestibular apparatus. Cupulolithiasis A theory for the pathogenesis of BPPV that proposes that otoconial debris attached to the cupula of the affected semicircular canal cause abnormal stimulation of the vestibular apparatus. Canalith repositioning procedures (CRP) A group of procedures in which the patient moves through specific body positions designed to relocate dislodged particles within the inner ear for the purpose of relieving symptoms of BPPV. e specific CRP chosen relates to the type of BPPV diagnosed. ese have also been termed canalith repositioning maneuvers or canalith repositioning techniques.
