The dizziness handicap inventory (DHI) is widely used to evaluate self-perceived handicap due to dizziness, and is known to correlate with vestibular function tests in chronic dizziness. However, whether DHI reflects subjective symptoms during the acute phase has not been studied. This study aims to investigate the correlations of subjective and objective measurements to highlight parameters that reflect the severity of dizziness during the first week of acute unilateral vestibulopathy.
Thirty-seven patients with acute unilateral vestibulopathy were examined. Patients' subjective perceptions of dizziness were measured using the DHI, Vertigo Visual Analog Scale (VVAS), Disability Scale (DS), and Activity-Specific Balance Scale (ABC). Additionally, the oculomotor tests, Romberg and sharpened Romberg tests, functional reach test, and dynamic visual acuity tests were performed. The correlation between the DHI and other tests was evaluated.
DHI-total scores exhibited a moderately positive correlation with VVAS and DS, and a moderately negative correlation with ABC. However, DHI-total score did not correlate with results of the Romberg, sharpened Romberg, or functional reach tests. When compared among four groups divided according to DHI scores, VVAS and DS scores exhibited statistically significant differences, but no significant differences were detected for other test results.
Our findings revealed that the DHI correlated significantly with self-perceived symptoms measured by VVAS and DS, but not ABC. There was no significant correlation with other balance function tests during the first week of acute vestibulopathy. The results suggest that DHI, VVAS and DS may be more useful to measure the severity of acute dizziness symptoms.
头晕残障量表（DHI）被广泛用于评估因头晕导致的自我感知残障，并且已知其与慢性头晕的前庭功能测试相关。然而，DHI是否能反映急性期的主观症状尚未得到研究。本研究旨在调查主观和客观测量之间的相关性，以突出反映急性单侧前庭病变第一周头晕严重程度的参数。
对37例急性单侧前庭病变患者进行了检查。使用DHI、眩晕视觉模拟量表（VVAS）、残障量表（DS）和特定活动平衡量表（ABC）测量患者对头晕的主观感受。此外，还进行了动眼神经测试、罗姆伯格和改良罗姆伯格测试、功能性伸展测试以及动态视力测试。评估了DHI与其他测试之间的相关性。
DHI总分与VVAS和DS呈中度正相关，与ABC呈中度负相关。然而，DHI总分与罗姆伯格、改良罗姆伯格或功能性伸展测试的结果无关。根据DHI评分分为四组进行比较时，VVAS和DS评分存在统计学显著差异，但其他测试结果未检测到显著差异。
我们的研究结果表明，DHI与通过VVAS和DS测量的自我感知症状显著相关，但与ABC无关。在急性前庭病变的第一周，与其他平衡功能测试无显著相关性。结果表明，DHI、VVAS和DS可能更有助于测量急性头晕症状的严重程度。
