How inner ear shape affects positional vertigo and its treatment
Biomechanical Mechanisms of Benign Paroxysmal Positional Vertigo
Researchers will build computer and physical models of the inner ear and design head-movement maneuvers to help people with complex positional vertigo.

What this research studies
The team will use imaging and statistical shape modeling to map how the semicircular canals vary between people. They will create computer simulations and physical models that reproduce different forms of canalith (ear debris) problems. Based on those models they will design and test “universal” canalith repositioning maneuvers meant to clear debris from all three canals in one sequence. They will also study diagnostic head impulse tests and lab experiments to link specific nystagmus patterns with types of canal blockage.
Who could benefit from this research
Good fit: Ideal candidates are people with recurrent or complex multi-canal benign paroxysmal positional vertigo or unclear positional vertigo where standard maneuvers have failed or provided inconsistent results.
Not a fit: People whose dizziness is due to non-BPPV causes (for example, vestibular migraine, Meniere’s disease, or central nervous system disorders) are unlikely to benefit from these repositioning-focused approaches.
Why it matters
Potential benefit: If successful, this work could produce repositioning maneuvers and diagnostic methods that work for more people and reduce repeat treatments for BPPV.
How similar studies have performed: Standard repositioning maneuvers already help many patients, but developing universal maneuvers based on detailed inner-ear shape modeling is a new approach with limited prior testing.
