本研究的目的是调查移动房间范式是否可以用于评估老年人跌倒风险。将一组年轻人（18-29岁）和两组有和没有福尔斯跌倒史的老年人（60-79岁）置于模拟移动室中。参与者站着不动，面对一个振荡的三维虚拟房间在前后平面上移动，三种类型的房间运动条件，连续振荡，离散前和离散后。年轻的成年人进行较少的姿势运动和连贯性的虚拟运动比老年组。老年跌倒者组表现出更多的姿势运动[压力中心（COP）长度，p < 0.05]，与物体运动的一致性更高（p = 0.07），稳定时间最长（p < 0.05）。一个虚拟的移动房间，结合时间的稳定性和自我运动的措施似乎有用的预测风险福尔斯。(c)2007 Elsevier B.

The purpose of this study was to investigate whether the moving room paradigm could be used to assess fall risk in older people. A group of young adults (18-29 years) and two groups of elderly adults (60-79 years) with and without a history of falls were placed into a simulated moving room. Participants stood still facing an oscillating three dimensional virtual room moving in the antero-posterior plane with three types of room movement conditions, continuous oscillatory, discrete anterior and discrete posterior. The young adults performed with less postural motion and coherence with the virtual motion than the older age groups. The group of elderly fallers exhibited more postural motion [center of pressure (COP) length, p < 0.05], a trend towards higher coherence with the object motion (p = 0.07), and the greatest amount of time-to-stability (p < 0.05). A virtual moving room incorporating measures of time-to-stability and egomotion appears useful in predicting risk for falls. (c) 2007 Elsevier B.V. All rights reserved.
