Video head impulse test (vHIT) artifacts are defined as spurious elements or disturbances in the recorded data that deviate from the true vestibulo-ocular reflex response. These artifacts can arise from various sources, encompassing technological limitations, patient-specific factors, or environmental influences, introducing inaccuracies in vHIT outcomes. The absence of standardized criteria for artifact identification leads to methodological heterogeneity. This narrative review aims to comprehensively examine the challenges posed by artifacts in the vHIT. By surveying existing literature, the review seeks to elucidate the multifaceted nature of artifacts arising from technological, patient-related, evaluator-related, and environmental factors.
视频头脉冲试验（vHIT）伪迹被定义为记录数据中偏离真实前庭眼反射反应的虚假元素或干扰。这些伪迹可能源于各种来源，包括技术限制、患者特定因素或环境影响，从而在vHIT结果中引入不准确因素。缺乏用于伪迹识别的标准化标准导致方法学上的异质性。本叙述性综述旨在全面审视vHIT中伪迹带来的挑战。通过查阅现有文献，该综述旨在阐明由技术、患者相关、评估者相关和环境因素引起的伪迹的多方面性质。
