[Purpose] The objective of this study was to determine the effects of virtual reality-based balance training on balance of the elderly. [Methods] The subjects were 32 healthy elderly people aged between 65 and 80, who were divided into a VR (virtual reality) training group (n=17) and a control group (n=15). The VR training group engaged in a 30-minute exercise session using Wii Fit three times a week for eight weeks, while the control group received no intervention. The balance of the two groups was measured before and after the intervention. [Results] According to the Romberg Test conducted to examine the effects of the training on balance, both the area covered by the body's center of pressure movement, and movement distances per unit area of the body's center of pressure envelope significantly decreased in the VR training group. Moreover, the two groups showed significant differences in balance. [Conclusion] Virtual reality training is effective at improving the balance of the healthy elderly. Thus, virtual reality training can be proposed as a form of fall prevention exercise for the elderly.
[目的] 本研究的目的是确定基于虚拟现实的平衡训练对老年人平衡能力的影响。[方法] 研究对象为32名年龄在65至80岁之间的健康老年人，他们被分为虚拟现实（VR）训练组（n = 17）和对照组（n = 15）。VR训练组每周使用Wii Fit进行三次30分钟的锻炼，持续八周，而对照组未接受任何干预。在干预前后测量两组的平衡能力。[结果] 根据用于检查训练对平衡影响的Romberg测试，VR训练组中身体压力中心移动所覆盖的面积以及身体压力中心包络每单位面积的移动距离均显著降低。此外，两组在平衡能力方面存在显著差异。[结论] 虚拟现实训练在改善健康老年人的平衡能力方面是有效的。因此，虚拟现实训练可被提议作为老年人预防跌倒的一种锻炼形式。
