这项研究的目的是为了更好地了解步态如何随着年龄的增长而变慢。分析了人体运动的运动学参数(速度、步长、周期、摆动和双支撑持续时间)，以及它们在减速过程中和有意调节速度过程中的相互关系。本实验对67名60~80岁以上的老年人进行了自由步态和快步态步行实验。这一群体与处于相同情况下的年轻群体进行了比较。结果表明，老年人步态的主要特征是步幅缩短，双支撑时相增多。然而，这些特性似乎更多地是由于老年人步态缓慢，而不是影响这一人群的更具体的变化，因为年轻受试者的缓慢步态中也观察到了相同的特征。此外，在这项研究中观察到的有意调节速度的能力并没有随着年龄的增长而改变。这些结果表明，如果考虑到速度，老年人的步态可以说是正常的。
The aim of this research was to better understand how gaits slows with age. We analyzed the kinematic parameters of locomotion (velocity, stride length, cycle duration, swing and double support durations), and their interrelationships both in the slowing process due to aging and in intentional modulations of velocity. The experiments were carried out on a group of 67 elderly adults (aged 60 to 80+) walking with a free gait and fast gait. This group was compared to a young population in equivalent situations. The results show that the main characteristics of the elderly gait are the shortening of strides and the increasing of the double support phase. However, these properties seem to be due to the slowness of the elderly gait more than to more specific alterations affecting this populations since identical features were also observed in the slow gait of the young subjects. Furthermore, the ability to intentionally modulate velocity observed in this study was not altered by aging. These results suggest that elderly gait can be said to be normal if one takes the velocity into account.
