Abstract
Background: Previous studies that compared foot pressures in boys and girls found that girls had greater peak pressures under the hallux than did boys. Only one of these studies considered plantar pressure measurements in children. The purpose of the study was to investigate the effect of gender on foot pressure measurements in children. Methods: This is a comparative study using the F-Scan pressure platform (F-Mat; Texscan® Boston, MA) on a sample of children attending a podiatric clinic. Pressure measurements and temporal parameters were measured in 61 children between the ages of 5 and 16 years. Associations between joint hypermobility and hallux valgus angle also were investigated. Results: Girls were found to have significantly greater peak pressure under the hallux, faster timing of heel contact to first metatarsal head loading, and a more medially placed center of pressure trajectory. No associations were found between these significant variables and hypermobility scores or hallux valgus angle. Conclusion: The results indicate that there are differences in pressure measurements between boys and girls, but the reasons for these remain unclear. Differences in pressure measurements in the feet of boys and girls may be useful in establishing the cause of foot pathologies for which a prevalence has been shown in boys or girls, such as hallux valgus deformity, which is known to be more frequent in females of all ages.
