In this study the kinematic gait parameters of healthy young and elderly subjects were compared with those of a group of patients with idiopathic gait disorder of the elderly (IGDE), a condition characterized by dysfunctional walking for which no underlying cause can be determined. The velocity and the temporal/distance gait kinematics were measured for self-selected fast, medium and slow speeds of walking. The elderly walk with a more cautious gait pattern than younger adults. This pattern is characterized by a slow walking speed and a reduced single support phase, with shorter but more frequent strides, and is even more marked in persons with IGDE. The slower the walking speed the more cautious this pattern becomes. The patients with IGDE not only walk far slower than a group of healthy age matched individuals but the range of speeds, from self-selected slow to fast, is much reduced and does not overlap that of the healthy elderly. With objective gait measurements this group might be better identified.
在本研究中，将健康年轻人和老年人的运动步态参数与一组患有老年特发性步态障碍（IGDE）的患者进行了比较，IGDE是一种以行走功能障碍为特征且无法确定潜在病因的病症。针对自我选择的快、中、慢步行速度测量了速度以及时间/距离步态运动学。老年人比年轻人行走时步态模式更为谨慎。这种模式的特点是步行速度慢、单支撑期缩短、步幅更短但更频繁，在患有IGDE的人群中更为明显。步行速度越慢，这种模式就越明显。患有IGDE的患者不仅行走速度远比一组年龄匹配的健康个体慢，而且从自我选择的慢到快的速度范围也大大缩小，且与健康老年人的速度范围没有重叠。通过客观的步态测量，这一群体可能会得到更好的识别。
