A teaching, training and test tool for the vestibulo-ocular reflex (VOR) system and its disorders, including BPPV. It demonstrates eye saccades, including those caused by canalithiasis (free-floating particles in the canals), and both functioning and dysfunctional VOR. It shows how BPPV is caused and treated.
aVOR demonstrates how head movement has an automatic influence on eye direction, the impact of dysfunction of the semicircular canals, their size, shape and location in the head, and the causes of nystagmus.
The application includes a Quiz Mode which presents the symptoms of various types of VOR dysfunction for the student to diagnose.
It is designed for college-level neuropsychology students and medical professionals, and incorporates the latest research. aVOR is sponsored by the University of Sydney, Australia.
