Pilot study: Biomechanical assessment of the plantar pressure distribution in healthy subjects using the pressure platform EcoWalk

Plantar pressure provides useful information to assess the feet's condition. These systems have emerged as popular tools in clinical environment. These systems present errors and no compensation information is presented by the manufacturer, leading to uncertainty in the measurements. Ten healthy subjects, 5 females and 5 males, were recruited. Lateral load distribution, antero-posterior load distribution, average pressure, contact area, force, and peak pressures in 12 plantar regions were recorded. The aims of this study were to assess repeatability of the EcoWalk system and identify the range of pressure values observed in the normal foot. The coefficient of repeatability was less than 4\% for all parameters considered. The peak pressure was found to be repeatable when it was analyzed by region.
