Learn how positional vertigo works by watching the crystals (aka "otoconia" or "otolith") fall and move through the semicircular canals of your inner ear anatomy with this educational model. We developed this anatomical model to promote the understanding of fluid dynamics as well as how our inner ear crystals respond to gravity when displaced in the canals. This model can demonstrate how BPPV repositioning techniques such as the Epley work. Perfect for use with patients, students, and clinical mentorship and training.
