Plantar pressure systems are increasingly being used to evaluate foot function in both research settings and in clinical practice. The purpose of this study was to investigate the reliability of the TekScan MatScan(R) system in assessing plantar forces and pressures during barefoot level walking.
Thirty participants were assessed for the reliability of measurements taken one week apart for the variables maximum force, peak pressure and average pressure. The following seven regions of the foot were investigated; heel, midfoot, 3rd-5th metatarsophalangeal joint, 2nd metatarsophalangeal joint, 1st metatarsophalangeal joint, hallux and the lesser toes.
Reliability was assessed using both the mean and the median values of three repeated trials. The system displayed moderate to good reliability of mean and median calculations for the three analysed variables across all seven regions, as indicated by intra-class correlation coefficients ranging from 0.44 to 0.95 for the mean and 0.54 to 0.97 for the median, and coefficients of variation ranging from 5 to 20% for the mean and 3 to 23% for the median. Selecting the median value of three repeated trials yielded slightly more reliable results than the mean.
These findings indicate that the TekScan MatScan(R) system demonstrates generally moderate to good reliability.
足底压力系统在研究和临床实践中越来越多地被用于评估足部功能。本研究的目的是调查 TekScan MatScan（R）系统在评估赤脚水平行走时足底力和压力的可靠性。
30 名参与者接受了为期一周的评估，评估变量包括最大力、峰值压力和平均压力的测量值。研究了足部的以下七个区域：脚跟、中足、第 3-5 跖骨趾关节、第 2 跖骨趾关节、第 1 跖骨趾关节、大脚趾和小脚趾。
使用三次重复试验的平均值和中位数值评估了可靠性。该系统显示出中等至良好的可靠性，表明在所有七个区域的三个分析变量的均值和中位数计算中，内类相关系数范围为 0.44 至 0.95，中位数为 0.54 至 0.97，变异系数范围为 5%至 20%，中位数为 3%至 23%。选择三次重复试验的中位数值比平均值产生了更可靠的结果。
这些发现表明，TekScan MatScan（R）系统通常具有中等至良好的可靠性。
