来自视觉和前庭传入的反射性输入产生晕动病和姿势不稳定。然而.视觉和前庭输入彼此之间的关系仍然不清楚。在这项研究中，我们研究了主观的疾病和平衡相关的症状和客观的平衡共济失调的视觉前庭冲突（VVC）刺激，使用虚拟现实诱导的发展。采用Graybiel和汉密尔顿的主观症状评价标准，患者的主观症状在VVC过程中逐渐加重。在VVC过程中未观察到客观姿势不稳定，但在VVC后立即发生。主观症状与客观共济失调之间存在时间差。我们的研究表明，VVC输入处理在不同的途径，造成主观自主症状和姿势不稳定的人。(C)2003爱思唯尔科学爱尔兰有限公司保留所有权利。
Conflicting inputs from visual and vestibular afferents produce motion sickness and postural instability. However. the relationship of visual and vestibular inputs to each other remains obscure. In this study, we examined the development of subjective sickness-and balance-related symptoms and objective equilibrium ataxia induced by visual-vestibular conflict (VVC) stimulation using virtual reality. The subjective symptoms evaluated by Graybiel's and Hamilton's criteria got gradually worse during the VVC. The objective postural instability was not observed during the VVC, but it occurred immediately after the VVC. There was a time lag between the subjective symptoms and objective ataxia induced by VVC. Our study suggests that the VVC inputs are processed in different pathways causing subjective autonomic symptoms and postural instability in humans. (C) 2003 Elsevier Science Ireland Ltd.
