Dix Hallpike test
Informed by recognized medical guidance
Overview
The Dix-Hallpike test is a simple, head-moving test that doctors use to help diagnose a common cause of vertigo (a spinning sensation) called benign paroxysmal positional vertigo (BPPV). During the test, you lie on a bed while the doctor quickly turns your head to one side and then lowers your head below the bed. This movement can trigger a brief episode of vertigo and tiny, jerky eye movements (nystagmus), which helps the doctor confirm the diagnosis.
Key facts
- The Dix-Hallpike test is the standard test used to diagnose BPPV, a condition caused by tiny calcium crystals moving into the wrong part of the inner ear.
- The test is quick and safe, usually taking about 30 seconds per side.
- A positive test means the doctor sees vertigo and nystagmus (uncontrolled eye movements) after the head movement.
The Dix-Hallpike test is very commonly performed when someone has symptoms of vertigo. BPPV itself is one of the most common causes of vertigo in adults.
The test is done on people who have episodes of vertigo when they move their head in certain ways, such as rolling over in bed, looking up, or bending forward. It is more often used in older adults, but can be done at any age.
