Associations between Dizziness Handicap Inventory scores and vestibular function tests: a cross-sectional survey

Objectives: This study aims to evaluate the relationship between subjective dizziness disability, as assessed by the Dizziness Handicap Inventory (DHI), and objective vestibular function test (VFT) results in patients presenting with dizziness. Methods: We conducted a retrospective review of 177 patients who completed the DHI, vertigo visual analog scale, and disability scale at their initial visit. Objective VFTs included videonystagmography with caloric testing, cervical vestibular evoked myogenic potential (cVEMP), and the sensory organization test (SOT). Statistical analyses were conducted to assess correlations and differences in DHI scores based on VFT results and clinical characteristics.Results: The DHI scores indicated a higher perceived dizziness handicap among female patients compared to males (p=0.012). Chronic dizziness was associated with elevated DHI scores in specific items (DHI-2, DHI-12, and DHI-21; p
