Assessment of the Medial Longitudinal Arch in children with Flexible Pes Planus by Plantar Pressure Mapping.

Plantar Pressure mapping was introduced as a new modality for assessment of the height of the medial longitudinal arch of the foot. Therefore, the aim of this study is to correlate the plantar pressure mapping readings of arch index contact force ratio (AICFR) in children with flexible pes planus with radiographic measurements and static plantar footprints in order to determine the reliability of pressure mapping as a modality for the assessment and follow up of the flat foot deformity.Radiographic measurements, foot prints, and pressure mapping scans were recorded for each foot at initial presentation and at latest follow up in 28 children (56 feet) with flexible pes planus.A positive correlation of pressure mapping results was found with the talo-first metatarsal angle, the calcaneal pitch angle, as well as the footprint scans (P < 0.001).This study demonstrated that plantar pressure mapping is a reliable and effective tool in screening, diagnosis, and follow up of children with flexible pes planus.
