Previous studies have demonstrated that pressure, force, area, and time measurements can be reliably collected from pedobaragraphic platforms, but no studies have analyzed geometric measurements. The purpose of this study was to establish the test-retest reliability of geometric measurements obtained during gait at a self-selected speed using a two-step approach. Data were collected on both feet for 10 healthy participants using the emed-x platform. Reliability of 15 geometric measurements was assessed using intraclass correlation coefficients (ICC). All 15 measurements were demonstrated to be reliable (ICC>0.8), with 12 measurements ICC>0.90. Collection of geometric measurements at a self-selected pace with the emed-x platform was found to be reliable and can be used for investigation in research settings.
