本研究的目的是调查前庭系统的贡献，在单眼视觉使用双耳双极前庭电刺激（GVS）的姿势控制。四个视觉（双眼，优势眼，非优势眼，没有视力）的条件下进行了测试，在GVS在5名健康受试者，而专注于一个目标放在他们面前。GVS诱发类似的上半身姿势摇摆在单眼和无视觉条件下，显着更大的那些在双眼视觉。阳极侧的地面反作用力的变化遵循相同的趋势，尽管优势眼的视觉数据与双眼视觉的数据没有显著差异。这些数据表明，在单眼视觉站立姿势控制的前庭传入信息的权重增加。(c)2008爱思唯尔爱尔兰有限公司保留所有权利。
The purpose of this study was to investigate the contribution of the vestibular system to Postural control during monocular vision using binaural-bipolar galvanic vestibular stimulation (GVS). Four visual (both eyes, dominant eye, non-dominant eye, and no vision) conditions were tested during GVS in five healthy subjects while focusing on a target placed in front of them. GVS evoked similar upper body postural sway during both monocular and no vision conditions that were significantly greater to those during binocular vision. Changes in ground reaction forces to the anode side followed that same trend, although data for vision with the dominant eye were not significantly different from that for binocular vision. These data suggest an increase in the weighting of vestibular afferent information during monocular vision for standing postural control. (c) 2008 Elsevier Ireland Ltd. All rights reserved.
