Reader response: Questionnaire-based diagnosis of benign paroxysmal positional vertigo

Kim et al.'s¹ 6-question strategy to diagnose benign paroxysmal positioning vertigo (BPPV) provides "acceptable" accuracy for BPPV diagnosis but less utility for type of BPPV. Reported accuracy of question 4—"to distinguish horizontal canal (HC) from posterior canal (PC) BPPV"—is largely due to vastly different frequencies of BPPV types.
