A Randomized Trial of the Canalith Repositioning Procedure

Abstract

The CRP was more effective than the expectation treatment for benign paroxysmal positional vertigo insofar as it provided faster recovery and required less dependence on medication. Complications of CRP were limited to 13.8% of patients.

Manobras para o tratamento da vertigem posicional paroxística benigna: revisão sistemática da literatura

“…After the papers were selected according to inclusion criteria and to methodology quality, there were five Epley's maneuver studies left, comparing them to placebos, no treatment or medication [28][29][30][31][32] . Lynn et al 28 compared Epley's maneuver (n=18) with placebo (n=15) without previous medication or vibration.…”

“…In two papers the authors advised patients to wear neck collar after the maneuver for 48 hours 28,32 . Such recommendation was not given in three other studies [29][30][31] . In three studies, patients were advised to follow restrictive behavior in the first days, such as: sleep while sitting for 48 horas 28,29,31 , avoid provoking movements 28,31,32 , and avoid sleeping over the affected side for one week 28 or five days 31 .…”

“…The groups were compared after one, two, three and four weeks, with results favoring the maneuver group, specially after one week (75.9% vs. 48.2%, respectively, p = 0.03), reducing from then on until there was no significant difference after one month (96% vs 90%, respectively, p = 0.336). However, patients who underwent Epley's maneuver, besides improving faster, used less anti-vertigo drugs (p=0.001) 30 . Sridhar et al 29 compared 20 patients who underwent Epley's maneuver to 20 control patients who used placebo only.…”

“…The patients were randomly distributed in two groups and Epley's maneuver with mastoid vibration in the experimental group (n=28), there was only one control group (n=19). Post-maneuver recommendations were given, such as to avoid vertigo-provoking movements, avoid sleeping with the head high for 48 hours and, if 30 studied adding Epley's maneuver to a group with medication and compared it to a group using medication alone (cinnarizin). No other recommendation was given after Epley's maneuver, not even the neck collar.…”

Manobra de Epley repetida em uma mesma sessão na vertigem posicional paroxística benigna

“…We proposed repetitive maneuvers in one single session, until nystagmus was no longer seen [28][29][30][31] or until vertigo and nystagmus stopped 23,[32][33][34] , without comparing Epley's maneuver efficacy repeated in the same session with one single maneuver per session.…”
