Figure 1. Dix-Hallpike Maneuver

Figure 1. A. The patient assumes a sitting position far enough back on the stretcher so that when she lies back her head will extend over the end of the stretcher. The head is turned 45 degrees to one side and is supported by the examiner. B. The patient rapidly assumes the supine position with the head extended over the bed 45 degrees and turned 45 degrees to the side. The examiner should continue to support the patient's head. Reproduction of vertigo and nystagmus is diagnostic of BPPV. The maneuver is repeated with head turned to the opposite side if necessary.
