- 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<0.05). Patients with abnormal caloric responses exhibited higher scores in several DHI items and subscales (DHI-4, DHI-12, DHI-14, DHI-17, DHI-19, DHI-23, physical, emotional, and functional; p<0.05). No significant differences were found in cVEMP results. Only one SOT condition (equilibrium score 5) showed a statistically significant but weak association with DHI scores (r=–0.151, p=0.045).
Conclusions
There were limited correlations between objective vestibular test outcomes and subjective dizziness disability. These findings underscore the multidimensional nature of dizziness and the importance of integrating subjective and objective measures for a comprehensive clinical assessment.
