The aim of this study was to assess the repeatability and reliability of the S-Plate® pressure platform in a group of healthy subjects.
Forty subjects, free from physical conditions that would affect normal gait, walked along a five-meter corridor while data were recorded from the pressure platform. A total of 10 steps (five each side) were obtained as well as five static trials; the same measurements were repeated one week later. Peak and mean plantar pressures and contact area were recorded for both dynamic and static trials. Additionally, weight supported on each limb was documented during static trials. To assess intrasession and intersession repeatability and reliability, the intraclass correlation coefficients (ICCs) and coefficient of variation (CoV) were calculated.
Taking the ICC values into account, every static and dynamic variable analysed showed moderate to excellent reliability and the CoV values were all below 12%.
Measurements of either static or dynamic plantar pressure variables with the S-Plate® pressure platform show good repeatability and reliability, and so it is useful for comparing steps within and between sessions.
本研究旨在评估S-Plate®压力平台在一组健康受试者中的可重复性和可靠性。
40名无影响正常步态身体状况的受试者沿着一条5米长的走廊行走，同时从压力平台记录数据。共获得10步（左右各5步）以及5次静态试验；一周后重复相同测量。记录动态和静态试验的足底峰值压力、平均压力和接触面积。此外，在静态试验期间记录每侧肢体支撑的体重。为评估组内和组间的可重复性和可靠性，计算组内相关系数（ICC）和变异系数（CoV）。
考虑ICC值，分析的每个静态和动态变量均显示出中度至高度的可靠性，且CoV值均低于12%。
使用S-Plate®压力平台测量静态或动态足底压力变量均显示出良好的可重复性和可靠性，因此它有助于比较不同组内和组间的步数。
