The purpose of this study was to develop a normative sample of temporal and spatial gait parameters for children (ages 1-10 years) using the GAITRite electronic walkway. Reliability of the GAITRite for assessing gait in children is similar to its reliability in adults. Normative temporal and spatial gait parameters have not been published using the GAITRite limiting clinicians and researchers ability to compare children to a large normative sample.
A total of 438 children (1-10 years) completed two walks of at least three steps each at a self-selected speed. The mean velocity, cadence, step length, stride length, heel to heel base of support, double support, and toe in/out angle for each age group was calculated.
Mean self selected velocity ranged from 82.05+/-25.28 to 133.63+/-15.44cm/s with the largest variability in subjects under 7 years of age. Cadence decreased with increasing age. Step length and stride length increased with age. Heel to heel base of support remained relatively constant between age groups with a mean of 8.77+/-2.74cm. Toe in/out angle was extremely variable for all age groups.
Developmental patterns of temporal and spatial gait parameters assessed using the GAITRite are similar to those reported in previous studies. However, the mean values for each age group differ slightly from previous gait study results. The normative data presented in this study will be useful to clinicians and researchers using the GAITRite electronic walkway to evaluate clinical populations. Data derived from other gait assessment tools and methods may not be a valid comparison to the values calculated using the GAITRite.
本研究旨在利用GAITRite电子步道为1至10岁儿童建立一个时间和空间步态参数的常模样本。GAITRite评估儿童步态的可靠性与其评估成人步态的可靠性相似。此前尚未发表过使用GAITRite得出的时间和空间步态参数常模,这限制了临床医生和研究人员将儿童与大型常模样本进行比较的能力。
共有438名1至10岁儿童以自行选择的速度完成了两次行走,每次行走至少三步。计算了每个年龄组的平均速度、步频、步长、步幅、足跟至足跟支撑基底、双支撑以及足尖内/外角度。
平均自行选择速度范围为82.05±25.28至133.63±15.44厘米/秒,7岁以下儿童的变异性最大。步频随年龄增长而降低。步长和步幅随年龄增长而增加。各年龄组间足跟至足跟支撑基底相对保持恒定,平均值为8.77±2.74厘米。所有年龄组的足尖内/外角度变化极大。
使用GAITRite评估的时间和空间步态参数的发育模式与先前研究报告的相似。然而,每个年龄组的平均值与先前步态研究结果略有不同。本研究中呈现的常模数据将有助于使用GAITRite电子步道评估临床人群的临床医生和研究人员。从其他步态评估工具和方法得出的数据可能无法与使用GAITRite计算得出的值进行有效比较。
