Benign paroxysmal positional vertigo in balance rehabilitation unit posturography.

Steven Williams

Benign Paroxysmal Positional Vertigo (BPPV) is characterized by sudden and quick episodes of vertigo, nausea and or positional nystagmus upon changes in head position, because of undue presence of calcium carbonate particles, resulting from the fractioning of statoconia from the utricular macula. Head movement causes the shifting of the calcium carbonate particles, causing endolymph acceleration, with consequent abnormal cupule deflexion.
