Effectiveness of particle repositioning maneuvers in the treatment of benign paroxysmal positional vertigo: a systematic review.

Background: Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo.

Purpose: The purpose of this systematic review was to determine whether patients diagnosed with posterior canal (PC) BPPV, based on positional testing, and treated with a particle repositioning maneuver will show the resolution of benign paroxysmal positional nystagmus (BPPN) on the Dix-Hallpike Test performed 24 hours or more after treatment.

Data Sources: Data were obtained from an electronic search of the MEDLINE, EMBASE, and CINAHL databases from 1966 through September 2009.

Effectiveness of careful bedside examination in assessment, diagnosis, and prognosis of vestibular neuritis.

Objective: To determine whether the use of 4 bedside tests (head-impulse, head-heave, head-shake, and vibration tests) can be as effective as the caloric test, a widely accepted standard, in the diagnosis and prediction of the time to recovery from vestibular neuritis.

Design: Inception cohort (1-year follow-up), criterion standard study.

Setting: Primary referral center.
