The purpose of this study was to investigate the effects of aging on gait for people 60 years old and above using gait variables commonly applied in sport shoe analysis. Thirty-eight subjects were divided into age groups: 60-69 years and 70-82 years. They walked along a carpeted walkway at a comfortable walking speed wearing a pair of their own walking shoes and a pair of laboratory supplied sports shoes. Kinetic and kinematic data were collected and subsequently analysed. Subjects of the older age group (70-82 years) displayed less movement in the subtalar joint during the support phase of walking with the personal shoes than subjects of the younger age group. Subjects of the older age group walked more slowly and exerted lower anterior-posterior forces with both the personal and laboratory shoes than subjects of the younger age group. Trends suggest (not statistically significant) that foot movement during mid-stance decreases with increasing age. It is speculated that this decrease in foot movement may be due to increased stiffness in the ankle and subtalar joint with age and/or due to a selection process of the older test subjects to prefer shoes with more support. Further research is needed to support or reject these speculations.
本研究的目的是使用运动鞋分析中常用的步态变量,调查衰老对60岁及以上人群步态的影响。38名受试者被分为两个年龄组:60 - 69岁组和70 - 82岁组。他们穿着自己的一双步行鞋和一双实验室提供的运动鞋,以舒适的步行速度沿着铺有地毯的通道行走。收集并随后分析了动力学和运动学数据。与年轻年龄组的受试者相比,老年年龄组(70 - 82岁)的受试者在穿着个人鞋子行走的支撑阶段,距下关节的运动较少。老年年龄组的受试者行走速度较慢,无论是穿着个人鞋子还是实验室提供的鞋子,其前后作用力都比年轻年龄组的受试者小。趋势表明(无统计学意义),随着年龄的增长,步态中期足部的运动减少。据推测,足部运动的这种减少可能是由于随着年龄增长,踝关节和距下关节的僵硬程度增加,和/或由于老年受试对象选择了更具支撑性的鞋子。需要进一步的研究来支持或反驳这些推测。
