这项研究记录了 656 名健康小学适龄儿童（5-13 岁）和 81 名年轻人（18-27 岁）以不同速度在水平走道上行走时的基本步态数据。它研究了步态速度的影响，并重新审视了步态成熟的问题。参与者穿着运动鞋沿着 GAITRite 走道以自行选择的慢速、自由和快速步行完成 6-8 次。结果测量（非标准化和标准化）包括步态速度、节奏、步长和步幅、步幅和步幅时间、支撑基础、单支撑和双支撑 (%)、站立持续时间 (%)、足部角度和相关的对称性测量。与自由速度相比，参与者慢速行走要慢 24%，快速行走要快 30% (p < 0.0001)。步频、步幅和步幅长度的标准化和非标准化测量值均随速度增加 (p < 0.001)，而步幅和步幅时间则减少 (p < 0.001)。作为步态周期的百分比，单支撑和站立持续时间随速度增加 (p < 0.001)，而双支撑则减少 (p < 0.001)。快速速度下的脚部角度明显小于自由速度和慢速速度时的脚部角度（更少的脚趾外翻）（p < 0.001），而支撑底座不受速度的影响。对称性测量不受年龄或速度的影响。步幅和步幅对称性差异（组合条件）下降了 0.8 厘米左右，而步态和站立时间、单支撑和双支撑的对称性差异下降了 0.7% 左右。临床医生和研究人员可以使用这些信息来评估儿童的步态。 (C) 2010 Elsevier B.V. 保留所有权利。
This study recorded basic gait data from 656 healthy primary school-aged children (5-13 years) and 81 young adults (18-27 years) whilst walking over-ground across a level walkway at varying speed. It investigated the effect of gait speed and re-examined the issue of gait maturation. Participants completed 6-8 walks at self-selected slow, free and fast speed along a GAITRite walkway whilst wearing athletic shoes. Outcome measures (non-normalized and normalized) were gait speed, cadence, step and stride length, step and stride time, support base, single and double support (%), stance duration (%), foot angle and associated symmetry measures. Compared to free speed, participants walked 24% slower for the slow speed and 30% faster for the fast speed (p < 0.0001). Both normalized and non-normalized measures of cadence, step and stride length increased with speed (p < 0.001) whereas step and stride time reduced (p < 0.001). As a percentage of the gait cycle, single support and stance duration increased with speed (p < 0.001) whereas double support reduced (p < 0.001). Foot angle was significantly less (less toe-out) for the fast speed than the free and slow speeds (p < 0.001) whereas support base was unaffected by speed. Symmetry measures were unaffected by age or speed. Step and stride symmetry differentials (combining conditions) fell around 0.8 cm, whereas symmetry differentials for step and stance time, single and double support fell around 0.7%. This information can be used by clinicians and researchers to assess the gait of children. (C) 2010 Elsevier B.V. All rights reserved.
