The Footscan platform is a useful tool for plantar pressure measurement. However, there is still controversy over whether or not the platform should be covered by top-layer during the test. This study was designed to compare the reliability of the Footscan platform and identify the differences of the foot loading parameters between without top-layer (WOT) and with top-layer (WT) protocols. Measurements were taken from thirty-two healthy subjects. Participants were tested with a Footscan platform using the WOT and WT protocols. Three trials were performed during two separate testing sessions with a 7-day interval. Peak pressure, contact time, contact area, and pressure-time integral at ten foot zones were recorded and calculated for intra- and intersession reliability using intraclass correlation coefficients (ICCs) and coefficients of variation (CVs). The reliability and values of the analyzed parameters for the two protocols were compared. Both protocols produced a moderate to good level of intra- and intersession reliability. Compared with the WT protocol, the WOT protocol showed higher ICCs, lower CVs, and higher values in most of the parameters analyzed. The results suggest that the WOT protocol showed better reliability than the WT protocol. We recommend not using the top-layer when performing the plantar pressure test.
Footscan 平台是一种有用的足底压力测量工具。然而，关于在测试过程中平台是否应该覆盖顶层仍存在争议。本研究旨在比较 Footscan 平台的可靠性，并确定无顶层（WOT）和有顶层（WT）协议之间足部加载参数的差异。该研究共纳入了 32 名健康受试者。参与者使用 Footscan 平台进行 WOT 和 WT 协议测试。两次单独的测试中，在 7 天的间隔内进行了三次试验。记录并计算了十个足部区域的峰值压力、接触时间、接触面积和压力时间积分，用于评估两次测试的日内和日间可靠性，采用组内相关系数（ICC）和变异系数（CV）。比较了两种方案的可靠性和分析参数的值。两种方案都产生了中等至良好的日内和日间可靠性。与 WT 方案相比，WOT 方案在大多数分析的参数中表现出更高的 ICC、更低的 CV 和更高的值。结果表明，WOT 方案的可靠性优于 WT 方案。我们建议在进行足底压力测试时不要使用顶层。
