Midfoot Pressure Analysis in Individuals with Flat Feet While Climbing Stairs Using a Pressure Sensing System

Abstract

Flat feet, or pes planus, present a prevalent condition impacting mobility and quality of life, warranting an understanding of its biomechanical implications. This study aimed to quantify pressure differentials in the midfoot region between individuals with flat feet and those without during stair ascent. The pilot study evaluated one individual with clinically diagnosed flat feet and one healthy individual, both meeting specific inclusion criteria. The participants ascended stairs while a pressure sensing system consisting of force-sensitive resistors (FSRs) recorded midfoot pressures.

The findings revealed that FSRs positioned along the medial longitudinal arch exhibited lower mean pressure values in individuals with flat feet, while FSRs on the lateral longitudinal arch displayed higher mean pressures in the same group. These results suggest a compensatory shift in pressure distributions, highlighting the altered loading patterns associated with flat feet. 

These findings have significant implications for physical therapy, underscoring the importance of arch strengthening exercises to improve foot stability and redistribute pressure more effectively. By integrating pressure mapping into rehabilitation strategies, therapists can create personalized treatment plans, ultimately improving outcomes for individuals with flat feet. This study contributes to the broader understanding of foot mechanics and emphasizes the need for targeted interventions in managing flat foot pathology.
