Repeatability of Arch Index

The repeatability of footprint digitization was determined as the mean intra-footprint coefficient of variation of the arch index of 27 footprints, all digitized twice. The within subject repeatability was determined as the mean intra-subject coefficient of variation of the arch index of 10 subjects, who had two footprints made and digitized each. The coefficient of variation within footprints was two percent, and the within subjects coefficient of variation was five percent, indicating that the arch index is a reliable and consistent measurement.
