Hypothesis: Implementation of the "aVOR app" into teaching courses at medical school enhances students' satisfaction with the course and increases their competence in treating benign paroxysmal positional vertigo (BPPV).

Background: BPPV is often underdiagnosed and left untreated. One problem in teaching the management of BPPV to health care professionals is the lack of simulation-based training tools.

The use of mastoid vibration with canalith repositioning procedure to treat persistent benign paroxysmal positional vertigo: A case report.

The Canalith Repositioning Procedure (CRP) was originally described as a non-invasive treatment for Benign Paroxysmal Positional Vertigo (BPPV) by Epley. Since its inception, the maneuver has undergone several modifications; and currently is performed in the absence of induced mastoid vibration (oscillation). Clinically, mastoid vibration may be used to assist in treatment of persistent cases of BPPV, where a simple CRP may fail to improve symptoms.

Affected-ear-up 120° maneuver for treatment of lateral semicircular canal benign paroxysmal positional vertigo.

Although several researchers have tried various canalith repositioning procedures for lateral canalolithiasis, a standard treatment has not been established. We adopt 120° rotation, which is anatomically appropriate because the principle of cure may be the fixing of pathological debris to the dark cells of the utricle. The aims of this study were to clarify the efficacy rate of the affected-ear-up 120° maneuver and to elucidate the appearance rate of lying-down nystagmus in patients with lateral canalolithiasis.

Barriers and facilitators to ED physician use of the test and treatment for BPPV.

Background: The test and treatment for benign paroxysmal positional vertigo (BPPV) are evidence-based practices supported by clinical guideline statements. Yet these practices are underutilized in the emergency department (ED) and interventions to promote their use are needed. To inform the development of an intervention, we interviewed ED physicians to explore barriers and facilitators to the current use of the Dix-Hallpike test (DHT) and the canalith repositioning maneuver (CRM).

A Case Study of High-Velocity, Persistent Geotropic Nystagmus: Is This BPPV?

Background And Purpose: Deciphering the cause for a persistent, direction-changing geotropic nystagmus can be difficult. Migraine and light cupula are two possible causes, though can be confused with benign paroxysmal positional vertigo (BPPV) affecting the horizontal semicircular canal. In migraine, the persistent geotropic nystagmus tends to be slow; in light cupula, the nystagmus has been illustrated to beat in the direction opposite that of prone positioning.

[Light cupulopathy: persistent direction changing positional nystagmus with a null plane].

The purpose of this study was to report two cases of light cupulopathy, and describe the characteristics of these cases and analysis the possible physiopathological mechanisms. The histories, clinical features, characteristics of nystagmus, and vestibular function, as well as audiologic results of the two patients with light cupula were analyzed. The two patients showed persistent geotropic direction changing positional nystagmus(DCPN)in the supine head roll tests.

Results: Both patients were treated successfully with manual or device-assisted canalith repositioning maneuvers, with no recurrence on the follow-up of 6 -18 months.

Clinical Practice Guideline: Benign Paroxysmal Positional Vertigo (Update).

Objective This update of a 2008 guideline from the American Academy of Otolaryngology-Head and Neck Surgery Foundation provides evidence-based recommendations to benign paroxysmal positional vertigo (BPPV), defined as a disorder of the inner ear characterized by repeated episodes of positional vertigo. Changes from the prior guideline include a consumer advocate added to the update group; new evidence from 2 clinical practice guidelines, 20 systematic reviews, and 27 randomized controlled trials; enhanced emphasis on patient education and shared decision making; a new algorithm to clarify action statement relationships; and new and expanded recommendations for the diagnosis and management of BPPV. Purpose The primary purposes of this guideline are to improve the quality of care and outcomes for BPPV by improving the accurate and efficient diagnosis of BPPV, reducing the inappropriate use of vestibular suppressant medications, decreasing the inappropriate use of ancillary testing such as radiographic imaging, and increasing the use of appropriate therapeutic repositioning maneuvers.
