Health-related quality of life in children with flexible flatfeet: a cross-sectional study.

Purpose: The effect of paediatric flexible flatfeet (PFF) on health-related quality of life (HRQOL) has not been investigated. In this prospective cross-sectional study, the HRQOL of children with PFF was compared to those with typically developing feet (TDF) using two validated measures. We hypothesised that reduced HRQOL would be observed in children with PFF.

Motion analysis to track navicular displacements in the pediatric foot: relationship with foot posture, body mass index, and flexibility.

Background: Increased navicular drop (NDro) and navicular drift (NDri) are associated with musculoskeletal pathology in adults. The aim of this study was to investigate navicular motion in children, with respect to foot posture, and identify altered patterns of motion that demonstrate midfoot dysfunction. Navicular motion in different activities was evaluated as well as the role of flexibility and body mass index (BMI).
