Table 1 Coefficient of variation determined for each day, foot region and group, considering data of mean and peak pressure. Data are expressed in percentage (%) considering mean and standard deviation data from each foot region. FF: forefoot; MF: midfoot; FR: rearfoot

From: Within and between-days repeatability and variability of plantar pressure measurement during walking in children, adults and older adults
