Abstract

Purpose : The study was designed to investigate the changes of plantar foot pressure by different loads during walking in flatfoot. Methods : Fifteen subjects with flatfoot were recruited along with their written informed consent. They were asked to walk on plate at a self-selected and comfortable speed with loads of 0, 5, 10, and 15kg. Three walking trials were obtained and then averaged for data analysis. Foot pressure were measured from RS-Scan system (RS-Scan system, RS scan Ltd., German) and contact area, maximum force were analyzed. Results : There were significant increases on midfoot and decreases on forefoot in contact area. And there were significant increases in maximum force of foot pressure of 2nd metatarsal bone and midfoot. Conclusion : These findings revealed that flatfoot increases risk factors of metatarsal bone with different loads. Therefore, patients of flatfoot must be careful during walking with loads or activities of daily living.
