The purpose of this study was to investigate the reliability of the TekScan MatScan system in assessing plantar forces and pressures during barefoot level walking. Methods 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. Results 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 to for the mean and to 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. Conclusions These findings indicate that the TekScan MatScan system demonstrates generally moderate to good reliability. Background During functional activities such as walking the human foot exerts a force upon the underlying surface and in turn a force of equal magnitude and opposite direction is exerted upon the foot. This force is commonly termed the ground reaction force 1 2 . Technological .
