What a positive finding suggests
Associated with benign paroxysmal positional vertigo, caused by displaced crystals in a semicircular canal.
◈ Behind the name
Margaret R. Dix (1902–1991) and Charles Skinner Hallpike (1900–1979), British ear specialists.

Please note: This page is an educational reference about clinical examination signs. A clinical sign supports — and never replaces — a full clinical evaluation, examination and appropriate testing. A sign being present does not by itself prove a diagnosis, and an absent sign does not rule one out. If you have symptoms that worry you, see a health professional.
