Abstract：
The computerized rotational head impulse test (crHIT) uses a computer-controlled rotational chair to deliver whole-body rotational impulses to assess the semicircular canals. The crHIT has only been described for horizontal head plane rotations. The purpose of this study was to describe the crHIT for vertical head plane rotations. In this preliminary study, we assessed four patients with surgically confirmed unilateral peripheral vestibular abnormalities and two control subjects. Results indicated that the crHIT was well-tolerated for both horizontal head plane and vertical head plane stimuli. The crHIT successfully assessed each of the six semicircular canals. This study suggests that the crHIT has the potential to become a new laboratory-based vestibular test for both the horizontal and vertical semicircular canals.
摘要：
计算机旋转头部脉冲测试（crHIT）使用计算机控制的旋转椅传递全身旋转脉冲以评估半规管。crHIT仅针对水平头部平面旋转进行了描述。这项研究的目的是描述垂直头部平面旋转的crHIT。在这项初步研究中，我们评估了4例经手术证实为单侧外周前庭异常的患者和2例对照受试者.结果表明，crHIT对水平头部平面和垂直头部平面刺激均具有良好的耐受性。crHIT成功地评估了六个半规管中的每一个。这项研究表明，crHIT有可能成为水平和垂直半规管的新的基于实验室的前庭测试。
