The elderly’s fall accidents develop into secondary disabilities, including the possibility of becoming bedridden due to fall-related fracture, disuse syndrome, etc. Consequently, such accidents can prove devastating to the elderly. This study examined to obtain useful findings for preventing falls of the elderly through a basic examination to clarify the mechanisms of sensing falls. A quasi-visual stimulus of a fall (screen image projected on a head-mounted display system) did not induce participants’ movement to avoid a fall. Then a degree of contribution of the visual system on postural stability during various standing conditions was examined. The visual contribution differed with sanding conditions. The visual contribution to postural stability may slightly smaller during dynamic compared to that during a quiet or static stance.

老年人跌倒事故发展为继发性残疾，包括因跌倒相关骨折、废用综合症等而卧床不起的可能性，此类事故对老年人来说可能是毁灭性的，本研究旨在获得预防跌倒的有用发现。老年人通过基本检查阐明了跌倒的感知机制。跌倒的准视觉刺激（投射在头戴式显示系统上的屏幕图像）并没有诱导参与者做出避免跌倒的动作。视觉系统在各种情况下对姿势稳定性的影响检查了站立条件下的视觉贡献因打磨条件而异，与安静或静态站立期间相比，动态期间对姿势稳定性的视觉贡献可能稍小。
