Introduction In Vestibular Testing (VT), caloric tests allow evaluation of unilateral weakness (UW) and directional preponderance (DP), where different criteria of normality are adopted in Brazil and worldwide. The Brazilian version of the Dizziness Handicap Inventory (Brazilian DHI) evaluates the impact of dizziness on the quality of life of an individual. Objectives The objective of this research is to evaluate the impact of dizziness on the quality of life of patients undergoing VT, and to relate these findings to the results obtained according to national and international criteria. Methods Cross-sectional analytic study of 235 patients referred for VT in two hospitals. The authors performed the Brazilian DHI, history, static, and dynamic balance tests, positional nystagmus, and the Dix-Hallpike maneuver, as well as vectoelectronystagmography. Subjects were divided into three groups according to UW and DP values. Descriptive statistics and comparisons between groups were performed, considering a significance level of 5% in all analyses. Results Patients groups had 20.9% men, and 79.1% women. There was no significant difference between groups for the scores obtained in the Brazilian DHI. There was, however, a statistically significant difference in the redistribution of individuals according to the UW and DP values. Conclusion There was no relationship between VT results and the impact of dizziness in the quality of life. A review of normal values for UW and DP adopted in Brazil is suggested, as well as the application of the Brazilian DHI as an additional tool to evaluate the impact of dizziness on quality of life in all patients undergoing VT.
引言 在前庭测试（VT）中，冷热试验可用于评估单侧前庭功能减退（UW）和优势偏向（DP），巴西和全球采用的正常标准有所不同。巴西版头晕残障量表（Brazilian DHI）评估头晕对个体生活质量的影响。目的 本研究的目的是评估头晕对接受VT患者生活质量的影响，并将这些结果与根据国内和国际标准获得的结果相关联。方法 对两家医院转诊进行VT的235例患者进行横断面分析研究。作者进行了巴西DHI、病史、静态和动态平衡测试、位置性眼球震颤、Dix-Hallpike试验以及矢量电子眼震图检查。根据UW和DP值将受试者分为三组。进行描述性统计和组间比较，所有分析的显著性水平为5%。结果 患者组中男性占20.9%，女性占79.1%。巴西DHI得分在各组之间无显著差异。然而，根据UW和DP值对个体重新分布存在统计学显著差异。结论 VT结果与头晕对生活质量的影响之间没有关系。建议对巴西采用的UW和DP正常值进行审查，并将巴西DHI作为评估头晕对所有接受VT患者生活质量影响的附加工具应用。
