The Semont maneuver, also known as the liberatory maneuver, is a physical therapy technique used to treat benign paroxysmal positional vertigo (BPPV). BPPV is a disorder arising from a problem in the inner ear, characterized by brief episodes of dizziness or vertigo. The Semont maneuver helps to reposition the otoliths (calcium carbonate crystals) that have moved into the semicircular canals of the inner ear.
