1引言追溯到20世纪90年代以前,临床医生评估耳石器的方法很有限。大多数情况下,医生只能通过患者在复杂的转椅上进行离心运动来评估椭圆囊。在离心过程中,患者被要求进行垂直度的主观心理物理测量,如主观视觉垂直(SVV)。但完成这些评估常给患者带来不适,且设备费用昂贵(超过15万英镑)。在20世纪90年代早期,科学文献中已有数个 1 Introduction Dating back to the 1990s, clinicians evaluated otolith devices in limited ways. In most cases, the physician can only evaluate the ellipsoid by moving the patient through a complex swivel chair. During centrifugation, the patient is asked to perform subjective psychophysical measurements of verticality, such as subjective visual verticality (SVV). However, it is often uncomfortable to perform these evaluations and the equipment is expensive (£ 150,000). In the early 1990s there were several scientific articles
