Development of a Low-Cost Foot Pressure Monitoring System for Basic Gait Analysis

Mayank Mundra

Abstract: Gait analysis provides critical insights into mobility, injury risk, and musculoskeletal health. This study evaluates plantar pressure distribution using a wearable insole system equipped with force-sensitive resistors (FSRs). Ten sensors on each foot recorded dynamic pressures during walking and were compared against a gold-standard pedoscan system. The Step Smart device captured overall pressure trends, with peak pressures at the heel and medial midfoot closely matching pedoscan readings (Sensor 1: Left 415 vs. 200, Right 385 vs. 300). Discrepancies were observed at high-pressure points such as the hallux and first metatarsal head (Sensor 2: Left 260 vs. 30, Right 105 vs. 15), likely due to sensor resolution limitations. Midfoot and arch sensors showed improved alignment (Sensor 4: Left 345 vs. 300, Right 368 vs. 260), while low-pressure regions remained consistent. Data from the Step Smart device is transmitted in real time via Wi-Fi to a connected computer, enabling immediate visualization and analysis. Despite minor underestimations, the device effectively reproduced temporal and spatial gait characteristics, demonstrating reliability in portable gait assessment. These findings highlight its potential for real-time clinical monitoring, rehabilitation, and home-based gait analysis, offering a cost-effective and accessible alternative to traditional laboratory pedoscans.
