Abstract

Introduction. The study aim was to compare lower extremity dominance, subtalar angle, balance, fall risk, and performance in younger adults with and without pes planus. Methods. A total of 80 physically active subjects participated in the study: 39 patients with flexible pes planus and 41 asymptomatic individuals. Arch height was assessed with the navicular drop test, the subtalar joint angles were determined with a goniometer, balance assessments were performed with the Biodex Balance System, and performance was evaluated with the single-leg jump and vertical jump tests. Furthermore, the strength of the gluteus medius muscles was measured with a dynamometer. Results. A significant difference was demonstrated for the subtalar angles (right and left), as well as the single-leg jump and vertical jump test results between asymptomatic subjects and those with pes planus (p < 0.05). Conclusions. it can be concluded that there was a decrease in the subtalar angle and performance in young adults with pes planus compared with asymptomatic participants. This finding suggests that prophylactic measures should be taken before the effects are seen in young adults.
