Body Sway When Standing and Listening to Music Modified to Reinforce Virtual Reality Environment Motion

The increased likelihood of falls as a consequence of aging or disease is generally associated with rising levels of body sway during stance.  The use of virtual reality (VR) for studying the role in vision in regulating body sway is well established, however the extent to which music incorporated into a virtual environment can influence sway is not understood. This dataset was collected as part of a study to explore the hypothesis that music manipulated to match VR motion provided by an Oculus Rift head mounted display can lead to increased levels of body sway. Twenty-eight subjects stood for 60 s on a balance platform that measured anterior posterior (AP) and medial lateral (ML) center of pressure movement (indicators of body sway).  While standing, the subjects experienced combinations of 3 visual conditions (VR translation in the AP direction at 0.1 Hz, no translation, and eyes closed) and 4 music conditions (Mozart’s Jupiter Symphony modified to scale volume at 0.1 Hz and 0.25 Hz, unmodified music, and no music) for a total of 12 trials. Analysis of the data using frequency domain measures may reveal the extent to which music influenced body sway.

随着年龄增长或疾病的影响，跌倒的可能性增加，通常与站立时身体摆动的水平上升有关。虚拟现实（VR）技术在研究视觉在调节身体摆动中所起作用方面已得到广泛应用，然而，将音乐融入虚拟环境中对身体摆动产生影响的程度尚不清楚。本数据集的收集是作为一项研究的一部分，旨在探讨以下假设：通过Oculus Rift头戴式显示器提供的VR运动与音乐进行匹配处理，能够导致身体摆动水平的增加。28名受试者在平衡平台上站立60秒，该平台测量了前后来回（AP）和内侧外侧（ML）压力中心运动（身体摆动的指标）。在站立过程中，受试者经历了3种视觉条件（前后来回方向上的VR平移，频率为0.1 Hz，无平移，以及闭眼）和4种音乐条件（莫扎特的《朱庇特交响曲》经过调整以0.1 Hz和0.25 Hz的频率改变音量，未经修改的音乐，以及无音乐）的组合，共计12次试验。使用频域测量方法分析数据，可能揭示音乐对身体摆动影响的程度。
