本研究的目的是比较健康，社区居住，年轻和老年男性之间的步态回避和适应策略。10名年轻男性（28.4 +/- 5.4岁）和10名老年男性（69.5 +/- 6.1岁）在水平上行走时进行了测试，避免了11.75 cm高的障碍物，并适应了11.75 cm的地板高度变化。三维，运动学和动力学分析进行双边。两个年龄组均使用相同的一般矢状面策略以避免和适应阻塞，但老年组的电极导线脚趾间隙显著降低。老年组的这些更危险的脚趾间隙被发现是由于有限的，额状面骨盆运动，较短的步幅，以及在矢状面内下肢能量模式的相互作用的细微差异。这些结果进行了讨论，在老年人口的体能下降。
The purpose of this study was to compare avoidance and accommodation strategies during gait between healthy, community-dwelling, young and elderly males. Ten young (28.4 +/- 5.4 years) and ten elderly (69.5 +/- 6.1 years) males were tested while walking on the level, avoiding a 11.75-cm-high obstacle, and accommodating a change in floor height of 11.75 cm. Three dimensional, kinematic, and kinetic analyses were performed bilaterally. Both age groups used the same general sagittal plane strategies in order to avoid and accommodate the obstructions, but the elderly group had significantly reduced lead toe clearances. These riskier toe clearances by the elderly group were found to be due to limited, frontal plane pelvic motion, shorter stride lengths, and subtle differences in the interplay of lower limb energetic patterns within the sagittal plane. These results are discussed with respect to diminishing physical capacity in the elderly populations.
