BPPV Diagnosis | Dix-Hallpike Maneuver [Performance, Interpretation]

The video tutorial explains the Dix Hallpike maneuver, a diagnostic test for BPPV, a type of vertigo. It covers the symptoms of BPPV, such as dizziness and room spinning, and provides a detailed guide on performing the maneuver. The tutorial also explains how to interpret nystagmus observed during the test to diagnose posterior or anterior canal issues. It discusses the implications of test results, including canalithiasis and cupulolithiasis, and previews further topics like the horizontal roll maneuver.
