The aVOR App Increases Medical Students' Competence in Treating Benign Paroxysmal Positional Vertigo (BPPV)

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).

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 aVOR app (aVOR = angular vestibulo-ocular reflex) works as a bionic labyrinth that simulates the activation of the semicircular canals by rotational acceleration and the resulting vestibular evoked eye movements.

In this prospective, randomized, controlled study, medical students at a university hospital were randomly assigned to two kinds of small instructional groups. Students of the control group (n = 67) practiced diagnostic and therapeutic maneuvers for BPPV on each other, while the participants of the study group (n = 46) used the aVOR app as a virtual patient in addition. At the end of the term, students were asked to arrange the steps of the canalith repositioning procedure in the correct order in a written test.

Quality of the teaching media was rated significantly better in the aVOR group (two-sided Mann-Whitney test: P < 0.00001). Significantly more students of the aVOR group than the control group arranged the steps of the canalith repositioning procedure correctly in the final exam (56.3% versus 25.9%, Fisher's exact test: P = 0.006).

Implementation of the aVOR app as a virtual patient into small instructional courses is well adopted by medical students and increases their competence in treating BPPV.
