Abstract

The aim of this study was to determine the reproducibility of plantar pressure parameters during normal stance and gait. For this purpose, two testing sessions were conducted on 2 separate days. Fifteen healthy subjects (10 males and 5 females) participated in the study and a plantar pressure platform was used to collect plantar pressure data. In each testing sessions, the subjects performed 10 single leg static balance trials, 10 two leg static balance trials and 10 gait trials. For static balance, the mean and maximum values of the mean pressure, the mean and maximum values of peak pressure and contact area were studied, while the mean and peak value of mean and peak pressure respectively were studied for gait. Intra-class correlation coefficient (ICC), coefficient of multiple correlation (CMC), coefficient of variation (CoV), standard error of measurement (SEM) and limits of agreement (LoA) were calculated for all the parameters. Results showed that ICC values were between 0.78 and 0.95 for the static balance parameters and between 0.78 and 0.99 for gait parameters. The above ICC values combined with small SEM values for the majority of parameters showed high reliability of the measurements in total. Additionally, the CV values were for the majority of the parameters lower than 10% indicating the high consistency of the measured parameter values. In conclusion, the results of the research make the tested plantar pressure platform a reliable tool for measuring plantar pressure parameters in both static balance and gait, on the condition that representative value is calculated from the average value of repeated trials and involves more than one trial.
