An Effective Home-Based Particle Repositioning Procedure for Posterior Canal Benign Paroxysmal Positional Vertigo (BPPV).

Patients with benign paroxysmal positional vertigo (BPPV) find it difficult to visit the hospital many times for a standard Epley's maneuver performed only by a specialist. The aim of this study was to compare the efficacy of a home-based particle repositioning procedure (HBPRP) with the standard Epley's maneuver in treating patients with posterior canal BPPV. A prospective non-blinded randomized controlled study was conducted. Patients were randomized into two groups, where one group received the standard treatment and other received a new HBPRP. The vertigo scale, duration of nystagmus during Dix-Hallpike test and frequency of vertigo, were documented on first, second and third visits, with complications noted during the second and third visits. These parameters were compared between both the groups following the treatment, during all visits. The patients were randomized into 2 arms with 15 each. Those belonging to group 1 received Epley's maneuver and group 2 received HBPRP. There was no significant difference in the baseline characteristics of patients in both groups. Both groups of patients had significant improvement of symptoms at the end of the study. A comparison of both groups at 2nd and 3rd visits showed no differences in frequency of vertigo, reduction in vertigo scale and duration of nystagmus following Dix-Hallpike test between both groups. HBPRP is a safe and effective procedure and can be taught as a home-based treatment for patients diagnosed with posterior canal BPPV.
