Individuals with vestibular dysfunction may experience visual vertigo (VV), in which symptoms are provoked or exacerbated by excessive or disorienting visual stimuli (eg, supermarkets). Individuals with VV are believed to be overly reliant on visual input for balance (ie, visually dependent). VV can significantly improve when customized vestibular rehabilitation exercises are combined with exposure to optokinetic stimuli. However, the frequency of treatment sessions (twice weekly for 8 weeks) and the equipment used (expensive and space consuming) make it difficult to incorporate these techniques into everyday clinical practice where exercises may be practiced unsupervised. The aim of this focused review is to provide an overview of recent findings investigating (a) responses of individuals with vestibular deficits to a customized exercise program incorporating exposure to optokinetic stimuli via a "high-tech" visual environment rotator or a "low-tech" DVD with and without supervision, and (b) the mechanism of recovery. Optokinetic stimulation will also be discussed in relation to other new innovations in vestibular rehabilitation techniques and future work.
患有前庭功能障碍的个体可能会出现视觉性眩晕（VV），其症状由过多或使人迷失方向的视觉刺激（例如超市）引发或加重。据信，患有 VV 的个体过度依赖视觉输入来维持平衡（即视觉依赖）。当将定制的前庭康复锻炼与向视动刺激暴露相结合时，VV 可显著改善。然而，治疗次数（每周 2 次，持续 8 周）和所使用的设备（昂贵且占用空间）使得难以将这些技术整合到日常临床实践中，因为这些练习可能在无人监督的情况下进行。本次重点综述的目的是概述最近的研究结果，这些结果调查了（a）前庭功能减退个体对包含向视动刺激暴露的定制运动方案的反应，该方案通过“高科技”视觉环境转椅或带有和不带有监督的“低科技” DVD 来实现，以及（b）恢复的机制。还将讨论视动刺激与前庭康复技术的其他新创新以及未来工作之间的关系。
