Benign Paroxysmal Positional Vertigo (BPPV) is a common inner ear disorder causing brief, intense spinning sensations (vertigo) triggered by specific head movements. From a vestibular physiotherapist's perspective, it's a mechanical problem with a mechanical solution. It occurs when tiny calcium carbonate crystals dislodge and migrate into the semicircular canals.
Vestibular physiotherapists diagnose the affected canal using tests like the Dix-Hallpike. Treatment involves specific canalith repositioning manoeuvres, such as the Epley manoeuvre for posterior canal BPPV, which guide the otoconia back into the utricle. These highly effective manoeuvres often resolve symptoms quickly, providing rapid relief from this debilitating condition.
