Comparison of the Plantar Pressure and Foot Function and Range of Motion in Distance Runners With the Normal, Pronated, and Supinated Feet During Static Standing

Abstract

Introduction: This study aimed to investigate the foot function, range of motion, plantar pressure, and plantar contact area in the distance runners with normal, pronated, highly-pronated, supinated, and highly-supinated foot posture groups during static standing. Materials and Methods: In this comparative cross-sectional study, a total of 75 distance runners were divided into 5 groups using the foot posture index. The foot function and knee and foot range of motion were assessed using the Foot And Ankle Ability Measure questionnaire (FAAM) and the goniometer, respectively. The mean of the plantar pressure percentage and the mean of the contact area on the forefoot and rearfoot were investigated during static standing. One-way ANOVA was used to compare the outcomes between the groups. Results: Among the groups, the normal foot group showed the highest scores in the activities of daily living subscale and sport subscale. Compared with the other groups, the highly-pronated foot group had a significantly greater range of motion in the ankle plantar flexion (P0.0001), respectively. Conclusion: Based on the results of this study, the foot posture is an important option that could affect function and range of motion of foot and ankle and distribution of the plantar pressure and plantar contact area.
