There are significant changes in gait across the life span, but particularly after the age of 70 years. This article reviews the physiology of gait and the motor control challenges during gait. The kinematics (motion) and the kinetics (moment and power) of normal gait of a database of healthy young and older adults are compared. Older subjects generate significantly lower peak ankle plantar flexor power during gait. The clinical significance of the reduction in ankle plantar flexion power is discussed.
一生中步态会发生显著变化，尤其是在70岁之后。本文回顾了步态的生理学以及步态过程中的运动控制挑战。比较了健康年轻人和老年人数据库中正常步态的运动学（运动）和动力学（力矩和功率）。老年受试者在步态中产生的踝关节跖屈肌峰值功率显著更低。讨论了踝关节跖屈功率降低的临床意义。
