A Chair-based Abbreviated Repositioning Maneuver (ChARM) for fast treatment of posterior BPPV

Experiences of patients and their health care providers with canalith repositioning maneuvers for benign paroxysmal positional vertigo: a qualitative systematic review protocol

OBJECTIVE

This review will synthesize the evidence on the experiences of patients undergoing canalith repositioning maneuvers (provided both by health care providers and by the patients themselves) and of health care providers offering canalith repositioning maneuvers in patients with benign paroxysmal positional vertigo.

INTRODUCTION

Despite having proven effectiveness for treating benign paroxysmal positional vertigo, the underutilization of canalith repositioning maneuvers by health care providers is a concern. Understanding the experiences of patients receiving canalith repositioning maneuvers and the experiences of the health care providers repositioning the canalith is imperative for the effective implementation of these maneuvers.

INCLUSION CRITERIA

This review will include qualitative studies describing the experiences of health care providers or patients with canalith repositioning maneuvers provided by health care providers or by patients themselves for benign paroxysmal positional vertigo, with or without other interventions, in any setting. Canalith repositioning maneuvers provided by non-qualified health professionals, non-professional caregivers, family caregivers, volunteer caregivers, or other informal caregivers will be excluded.

METHODS

MEDLINE, Embase, Cochrane CENTRAL, PsycINFO, Scopus, Web of Science, and CINAHL will be searched. Gray literature will be searched using OpenGrey, PsyArXiv, bioRxiv, medRxiv, and Google Scholar. Articles published in English will be considered, regardless of the publication date. Studies will be screened and critically appraised for methodological quality by 2 independent reviewers. The standardized JBI data extraction tool will be used, and the meta-aggregation approach for data synthesis and the ConQual approach for confidence evaluation will be followed.

Update on benign paroxysmal positional vertigo

Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo worldwide. This review considers recent advances in the diagnosis and management of BPPV including the use of web-based technology and artificial intelligence as well as the evidence supporting the use of vitamin D supplements for patients with BPPV and subnormal serum vitamin D.

Benign Positional Paroxysmal Vertigo Treatment: a Practical Update

PURPOSE OF THE REVIEW

To define the best up-to-date practical approach to treat benign paroxysmal positional vertigo (BPPV).

RECENT FINDINGS

Both posterior and horizontal canal BPPV canalith repositioning maneuvers (Semont, Epley, and Gufoni's maneuvers) are level 1 evidence treatment for evidence-based medicine. The choice of maneuver (since their efficacy is comparable) is up to the clinician's preferences, failure of the previous maneuver, or movement restrictions of the patient. Maneuvers for controversial variants, such as anterior canal and apogeotropic posterior canal BPPV, have weaker evidence of efficacy. Despite this, these variants are increasingly diagnosed and treated. Maneuvers also play a role in the differential diagnosis with central vestibular disorders. Chair-assisted treatment may be of help if available while surgical canal plugging should be indicated in selected same-canal, same-side intractable severe BPPV. The primary evidence-based treatment strategy for BPPV should be physical therapy through maneuvers. Despite the high success rate of liberatory maneuvers, there is a low percentage of subjects who have unsatisfactory outcomes. These patients need to be investigated to identify recurrences, multiple canal involvement, associated comorbidities (migraine, persistent postural perceptual dizziness), or risk factors for recurrences (low vitamin D serum level). Future research should also identify the optimum maneuvers for variants whose diagnosis and treatment are still a matter of some debate.
