Clinical Results of the Modified Canalith Repositioning Maneuver

Vibration With the Canalith Repositioning Maneuver: A Prospective Randomized Study to Determine Efficacy

“…In the present study, our single‐treatment success rate of 93.1% compared favorably with previously published success rates (44%–88%) and was unaffected by the inclusion of vibration. 2–12 Vibration as an independent variable did not improve treatment success rate or decrease the number of cycles required for successful treatment. Although there was a trend for decreased long‐term relapse rates in the group receiving CRP with vibration, this did not reach statistical significance.…”

“…The efficacy of canalith repositioning for the treatment of BPPV has been well established in numerous studies. 2–14 Most patients can be treated efficiently and effectively in one visit. We pointed out in a previous study that there was a significant percentage of patients requiring more than one treatment (25.2%).…”

“…Benign paroxysmal positional vertigo (BPPV) is one of the most common forms of dizziness and can be treated effectively with the canalith repositioning (CRP) maneuver. 1–14 Benign paroxysmal positional vertigo is thought to result from the movement of dense, free‐floating particles within one or more of the semicircular canals of the inner ear. The CRP maneuver was developed to clear these floating particles (otoliths) from the semicircular canals, providing rapid relief of vertiginous symptoms that could be proved by position.…”

“…The CRP maneuver is performed in an outpatient setting, with slight variations in technique depending on author. 2–14 One controversial variable involved in the procedure is the use of mastoid vibration, which has been thought to promote otolith mobilization and improve success rates. Li 11 reported a 1‐week prospective study in which CRP with vibration resulted in a 70% success rate in relieving nystagmus, with no success in the vibration‐free group.…”

Variables Affecting Treatment in Benign Paroxysmal Positional Vertigo

“… 6–9 Canalith repositioning is thought to clear the offending particles out of the semicircular canals by a series of rotational maneuvers and has demonstrated good efficacy in providing rapid and long‐lasting relief of symptoms. 10–17 Treatment requires only one treatment visit in most patients. However, there are a significant number of patients who require multiple treatment visits for relief or develop rapid recurrence of their symptoms.…”
