Optimizing Testing for BPPV - The Loaded Dix-Hallpike.

Objectives: Although the Dix-Hallpike testing is generally considered as the gold standard for the identification of the posterior canal benign paroxysmal positional vertigo (BPPV), we investigated a modification of the maneuver termed the "loaded Dix-Hallpike."

Study Design: Prospective randomized controlled trial.

Materials And Methods: Twenty-eight patients participated in this prospective study comparing the standard Dix-Hallpike (S-DH) to the loaded Dix-Hallpike (L-DH) test.
