Background: The Thai version of Dizziness Handicap Inventory (DHI-T) may be useful for primary care units to make decisions regarding the referral of patients with dizziness to balance specialists.
Objective: To evaluate the correlations between DHI-T scores and Cervical Vestibular Evoked Myogenic Potential (cVEMP) and caloric test results; and to compare DHI-T scores.
Methods: Subjects were 165 patients with dizziness: 144 patients in the experimental group showed an abnormal cVEMP test and/or caloric test results, 21 patients who had normal tests results were in a control group. The experimental group was divided into three subgroups: Ex-1 (abnormal cVEMP response only), Ex-2 (abnormal caloric response only), and Ex-3 (abnormal cVEMP and caloric response).
Results: The participants had a weak but statistically significant correlation between DHI-T scores and caloric test, and cVEMP test. Additionally, DHI-T score of the experimental group was significantly higher than the control group. The Ex-3 subgroup showed a higher DHI-T score than the other two subgroups, although it was statistically non-significant.
Conclusion: A higher DHI-T score is more likely to be associated with abnormal vestibular test results. Additionally, patients with dizziness who reported more than 25 points on their DHI-T scores were also more likely to have an abnormal caloric and/or cVEMP test results. Therefore, the DHI-T may be used to predict the vestibular test results of patients with dizziness and used as one of the referral criteria.
