Abstract

One's ability to maintain their center of mass within their base of support (i.e., balance) is believed to be the result of multisensory integration. Much of the research in this literature has focused on integration of visual, vestibular, and proprioceptive cues. However, several recent studies have found evidence that auditory cues can impact balance control metrics. In the present study, we sought to better characterize the impact of auditory cues on narrow stance balance task performance with different combinations of visual stimuli (virtual and real world) and support surfaces (firm and compliant). In line with past results, we found that reducing the reliability of proprioceptive cues and visual cues yielded consistent increases in center-of-pressure (CoP) sway metrics, indicating more imbalance. Masking ambient auditory cues with broadband noise led to less consistent findings; however, when effects were observed they were substantially smaller for auditory cues than for proprioceptive and visual cues - and in the opposite direction (i.e., masking ambient auditory cues with broadband noise reduced sway in some situations). Additionally, trials that used virtual and real-world visual stimuli did not differ unless participants were standing on a surface that disrupted proprioceptive cues; disruption of proprioception led to increased CoP sway metrics in the virtual visual condition. This is the first manuscript to report the effect size of different perturbations in this context, and the first to study the impact of acoustically complex environments on balance in comparison to visual and proprioceptive contributions. Future research is needed to better characterize the impact of different acoustic environments on balance.

听觉线索、本体线索和视觉线索对人类平衡的共同贡献。
一个人能够将重心保持在支撑基础内(即平衡),这被认为是多感官整合的结果。这篇文献中的大部分研究都集中在视觉、前庭和本体感觉线索的整合上。然而,最近的几项研究发现,有证据表明听觉线索会影响平衡控制指标。在本研究中,我们试图更好地描述视觉刺激(虚拟和现实世界)和支撑表面(稳固和顺从)的不同组合下,听觉线索对窄站平衡任务表现的影响。与过去的结果一致,我们发现,本体感觉线索和视觉线索的可靠性降低会导致压力中心(CoP)摇摆指标的持续增加,表明存在更多的不平衡。用宽带噪声掩盖环境听觉线索导致结果不太一致;然而,当观察到效果时,听觉线索的效果明显小于本体感觉和视觉线索的效果,而且方向相反(即,在某些情况下,用宽带噪声掩盖环境听觉线索可以减少摇摆)。此外,使用虚拟和真实世界视觉刺激的试验没有差异,除非参与者站在破坏本体感觉线索的表面上;本体感觉的破坏导致虚拟视觉条件下CoP摇摆指标的增加。这是第一份报告这种情况下不同扰动的影响大小的手稿,也是第一份研究与视觉和本体感觉贡献相比,声学复杂环境对平衡的影响的手稿。未来的研究需要更好地描述不同声学环境对平衡的影响。

期刊介绍: Multisensory Research is an interdisciplinary archival journal covering all aspects of multisensory processing including the control of action, cognition and attention. Research using any approach to increase our understanding of multisensory perceptual, behavioural, neural and computational mechanisms is encouraged. Empirical, neurophysiological, psychophysical, brain imaging, clinical, developmental, mathematical and computational analyses are welcome. Research will also be considered covering multisensory applications such as sensory substitution, crossmodal methods for delivering sensory information or multisensory approaches to robotics and engineering. Short communications and technical notes that draw attention to new developments will be included, as will reviews and commentaries on current issues. Special issues dealing with specific topics will be announced from time to time. Multisensory Research is a continuation of Seeing and Perceiving, and of Spatial Vision.
