Dix-Hallpike maneuver

  • The Dix-Hallpike maneuver is one of the most important tests for patients who experience true vertigo. This test involves having the patient lie back suddenly with the head turned to one side.

  • The test results are considered abnormal if the patient reports vertigo and exhibits a characteristic torsional (ie, rotary) nystagmus that starts a few seconds after the patient lies back (latency), lasts 40-60 seconds, reverses when the patient sits up, and fatigues with repetition (see Medscape Reference article Benign Paroxysmal Positional Vertigo).
