Foot Plantar Pressure Measurement System for Static and Dynamic Condition

Abstract

The purpose of this paper is to measure human foot pressure at various important points and to provide the proper diagnosis for treating the post-operative orthopedic patients. Measurement of the human foot pressure distribution can provide vital information and is of great value for medical diagnostics. The distribution of human plantar pressure data depends on the conditions of the foot such as foot structure, function, the posture control of the entire body and gait. This device data will contribute greatly to the diagnosis, estimation of surgery and a better understanding of the pathogenesis of diseased foot with abnormal pressure distribution. The device will measure the foot pressure with the help of FSR, force sensitive resistor sensors which are placed on the upside of the sole of shoe. These sensors are connected to the Arduino Mega 2560. A custom-made software is created using LabVIEW. The patient’s details can be fed in and are saved in this software and when executed, the pressure data values collected is converted into digital pattern and a pedobarography is generated. This pedobarography image is displayed and saved in a word document and thus, enables the doctors to examine the foot pressure based on the deduced results.
