The study was designed to determine the reliability of temporal-spatial gait parameters in children with motor disabilities in two conditions: bare foot and with shoes and orthoses.
: Nineteen children (mean age of 6.8 years) with Gross Motor Functional Classification System levels I-III participated.
Participants walked over the GAITRite(R) Walkway System and gait velocity (cm/sec), cadence (steps/min), stance time (% gait cycle), stride length (cm), base width (cm), and cycle time (sec) were evaluated.
The single and three-trial average relative reliability estimates of the intraclass correlation coefficients met the minimum reliability coefficient criteria of 0.80.
This was an initial attempt to evaluate the reliability of an instrumented walkway system. Further study should include more participants and address age, functional limitations, diagnoses, and use of assistive devices.
本研究旨在确定运动功能障碍儿童在两种情况下（赤足以及穿着鞋子和矫形器）时空步态参数的可靠性。
19名粗大运动功能分类系统I - III级的儿童（平均年龄6.8岁）参与了研究。
参与者在GAITRite(R)步道系统上行走，并评估步态速度（厘米/秒）、步频（步/分钟）、站立时间（%步态周期）、步幅长度（厘米）、步宽（厘米）和周期时间（秒）。
组内相关系数的单次和三次试验平均相对可靠性估计值符合最低可靠性系数标准0.80。
这是评估仪器化步道系统可靠性的初步尝试。进一步的研究应纳入更多参与者，并涉及年龄、功能限制、诊断以及辅助设备的使用。
