The purpose of this study was to determine if scores between 0 and 30 (mild), 31 and 60 (moderate), and 61 and 100 (severe) on the Dizziness Handicap Inventory (DHI) differentiated a person's functional abilities.
Retrospective case series.
Tertiary balance outpatient center.
Patients (n = 85; mean age, 61 years) with a variety of vestibular diagnoses participated.
Patients completed the DHI, the Dynamic Gait Index (DGI), the 5 times sit to stand test (FTSST), the Activities-specific Balance Confidence (ABC) scale, gait speed, and the Timed "Up & Go" (TUG) during the same session. Reported numbers of falls within the last 4 weeks were recorded.
The DGI, FTSST, ABC, gait speed, TUG, and gait speed were compared among DHI groups.
Significant differences were identified using an analysis of variance between DHI groups on the DGI, the FTSST, ABC, and number of falls (p < 0.05). A significant difference was found between DHI groups (mild vs. severe and moderate vs. severe) on the DGI (p < 0.05) with greater DHI scores exhibiting more impaired walking. The FTSST was different between DHI groups mild and severe and DHI groups moderate and severe (p < 0.05), with slower FTSST scores with higher DHI scores. Reported falls were higher among the severe DHI group and the other 2 DHI groups (p < 0.05). All 3 DHI groupings were different from each other on the ABC (p < 0.001).
Patients who perceive a greater handicap as a result of dizziness demonstrate greater functional impairment than patients who perceive less handicap from dizziness.
本研究的目的是确定头晕残障量表（DHI）得分在0至30分（轻度）、31至60分（中度）和61至100分（重度）之间是否能区分一个人的功能能力。
回顾性病例系列研究。
三级平衡门诊中心。
参与研究的患者（n = 85；平均年龄61岁）患有多种前庭疾病。
患者在同一次就诊时完成DHI、动态步态指数（DGI）、5次坐立试验（FTSST）、特定活动平衡信心（ABC）量表、步速和定时起立行走测试（TUG）。记录过去4周内报告的跌倒次数。
比较DHI各分组之间的DGI、FTSST、ABC、步速、TUG和跌倒次数。
通过方差分析发现，DHI各分组在DGI、FTSST、ABC和跌倒次数方面存在显著差异（p < 0.05）。在DGI方面，DHI各分组之间（轻度与重度、中度与重度）存在显著差异（p < 0.05），DHI得分越高，行走功能受损越严重。DHI轻度与重度分组以及中度与重度分组之间的FTSST存在差异（p < 0.05），DHI得分越高，FTSST得分越慢。重度DHI组的报告跌倒次数高于其他两个DHI组（p < 0.05）。ABC在所有3个DHI分组之间均存在差异（p < 0.001）。
与头晕导致的残障感较轻的患者相比，因头晕而感到残障感较重的患者表现出更严重的功能障碍。
