Infrared computerized stroboscopic photometry was used to measure the kinematic profile of walking of 20 young adults and 20 neurologically healthy elderly people. Compared with the young adults, the elderly exhibited 17-20% reductions in the velocity of gait and length of stride. The elderly also exhibited comparable reductions in the maximum toe-floor clearance, arm swing, and rotations of the hips and knees, but these alterations in gait were attributable to the reduction in stride length, which may have non-neurological causes. The influence of reduced gait velocity and stride length on the other characteristics of walking must be considered when evaluating the pattern of walking in elderly people.
采用红外计算机频闪光度法测量了20名年轻成年人和20名神经功能正常的老年人的行走运动学特征。与年轻成年人相比，老年人的步态速度和步幅长度降低了17%-20%。老年人在最大足尖-地面间隙、手臂摆动以及髋部和膝部旋转方面也有类似程度的降低，但这些步态改变归因于步幅长度的减小，这可能有非神经学原因。在评估老年人的行走模式时，必须考虑步态速度和步幅长度降低对行走其他特征的影响。
