How to Diagnose BPPV: A Step-by-Step Guide
Published: Jun 11, 2024
Learn how doctors diagnose BPPV with a simple in-office procedure.
Understanding the Dix-Hallpike Maneuver
The Dix-Hallpike maneuver is a key diagnostic tool for BPPV. It involves positioning the patient in a way that provokes vertigo symptoms, allowing doctors to observe eye movements called nystagmus. This helps confirm the presence of BPPV and identify which ear is affected.
Performing the Maneuver
During the Dix-Hallpike maneuver, the patient sits upright before quickly lying back with their head turned to one side. The doctor observes for signs of vertigo and nystagmus. This process is repeated on both sides to determine which ear is affected.
Interpreting the Results
If the test provokes vertigo and nystagmus, BPPV is likely present. The side and type of nystagmus observed guide treatment decisions. If the results are unclear, further testing may be necessary to rule out other causes.
