Influência de sexo e idade na estrutura do pé e pressão plantar em adultos assintomáticos

Abstract

Abstract The aim of the study was identify the influence of gender and age of healthy adults on the foot structure and the plantar pressure during gait. Sample comprising 608 women and men participants. To identify the structure of the foot, anthropometric measurements of both the total and the truncated length of the foot, the width of the forefoot, and the heights of the back and navicular were taken. Peak pressure and plantar contact area in three foot-masks (forefoot, middle foot, and hindfoot) were considered markers of plantar pressure. The data were analyzed by two-way variance analysis. No significant influence of age on the foot structure dimensions was identified; however, women presented measures equivalent to the five significantly smaller anthropometric markers. As for the peak plantar pressure, both males and females showed statistically similar values, but significant differences were observed for age. As to the plantar contact area, while age did not have significant influence, men showed significantly higher values in the three foot-masks. The findings suggest that gender influences the foot structure and the plantar contact area, while age influences the peak of plantar pressure.
