中老年人步态指标与衰老关系的研究

分析139名中老年人在正常步行下的步态,研究从中年到老年这一衰老过程中步态指标的变化。结果表明,在周期的划分,步长与步速,髋、膝、踝及力的变化,中年人与老年人存在较大差别,老年人的下肢肌肉收缩能力下降,脚跟着地、踝跖屈和屈膝等动作变缓慢,仲髋动作不充分,摆动腿抬高的程度降低,行走时拖拉。

The Relationship between Consenescence and the Gait Norm of Elderly People

Analysis of 139 ordinary elderly people's gait in normal walking was made to study the variation of the gait norm during the aging course from middle age to the old. It is shown that there existed a substantial difference among middle aged and old people in the division of cycles, pace length and speed, hip, knee, and ankle angles, and curves of force in steps. Such data revealed that in the course of aging a series of changes took place, such as decrease of lower limbs'muscle contraction, slowing of heel landing, insufficiency of knee flexion, decrease of the extent and height of leg lifting, and sluggishness and preference of stability to speed in walking.
