目的本研究的目的是评估初始杆位置对主观视觉垂直（SVV）倾斜的影响，并探讨性别和年龄对该初始位置引起的SVV倾斜的影响。研究设计前瞻性横断面研究。设置三级转诊中心。患者本研究包括6598例连续患者与大范围的前庭障碍和333名对照组。平均年龄55岁（3-97岁），性别比为0.6。干预SVV的测量方法是在完全黑暗中以45 °左右交替的方式呈现磷光棒12次。患者被要求更换杆垂直与远程control.Results平均而言，SVV在每次迭代倾斜的杆介绍的一方。它在女性受试者中更强，在年轻人中（50）。这也是较高的左前庭损失的患者相比，那些有权利involvement.Conclusions这些影响表明，短期视觉记忆和多感觉皮层处理干扰SVV测量。
Objective The aim of this study was to evaluate the effect of initial rod position on the subjective visual vertical (SVV) tilt and to investigate the effect of sex and age on the SVV tilt induced by this initial position.Study Design Prospective cross-sectional study.Setting Tertiary referral center.Patients The study included 6598 consecutive patients with a large range of vestibular disorders and 333 control subjects. The mean age was 55 years (range, 3-97), and the sex ratio was 0.6.Intervention SVV was measured by presenting a phosphorescent rod 12 times in total darkness with a 45-degree deviation from the vertical alternatively on the right and left. The patient was asked to replace the bar vertically with a remote control.Results On average, SVV at each iteration was tilted to the side of the rod presentation. It was stronger in female subjects, in younger individuals (50). It was also higher in patients with a left vestibular loss in comparison to those with a right involvement.Conclusions These effects suggest that short-term visual memory and multisensory cortical processing interfere with SVV measurements.
