Benign Paroxysmal Positional Vertigo (BPPV) is a treatable disorder that presents as brief spells of vertigo occurring as a person changes position. Oftentimes, people report a spinning sensation when they roll in bed or when they get up first thing in the morning.
The departments of vestibular rehabilitation at Banner – University Medical Center Phoenix and Macias Otology have published two outcome studies in the journal Laryngoscope regarding BPPV.
The first study, "Variables Affecting Treatment in BPPV," was a retrospective review of 259 patients. The study showed that completing the Canalith Repositioning Maneuver (aka: the Epley Maneuver) resulted in a 98.4 percent success rate with only one to three visits to the vestibular clinic.
The second study, "Vibration with the Canalith Repositioning Maneuver: A Prospective Randomized Study to Determine Efficacy," was published in April 2004. The result was that the use of vibration behind the ear with BPPV provided no additional benefit in initial treatment success or in reducing long-term rates when included in the canalith repositioning maneuver.
The Banner – University Medical Center Phoenix vestibular clinic continues to develop and perform outcome studies that support the positive effect of vestibular rehabilitation for the population suffering from dizziness and disequilibrium.
