Rehabilitation Benign Paroxysmal Positional Vertigo: Symptoms and Causes By Centers for Rehab Services, June 18, 2018 Benign Paroxysmal Positional Vertigo, also known as BPPV, is the most common cause of vertigo. This condition can lead to sudden, brief spells of dizziness, triggered by certain movements or head positions. BPPV is a problem of the inner ear. It occurs when calcium carbonate crystals within the ear become dislodged and move to the semicircular canals, where they aren’t supposed to be. Find locations for UPMC Centers for Rehab Services. Physical therapists at UPMC Centers for Rehab Services can treat BPPV through a series of guided head movements. Medication may help lessen the nausea and dizziness associated with BPPV, but they will not solve the underlying problem. BPPV can happen as a result of trauma, disease, inner ear infection, intubation, and more.
