Abstract:
A measurement system has been developed to continuously record pressure data between the sole of the foot and the shoe. Five force sensing resistors are mounted to an insole suitable for shoe insertion. The sensors are located at the heel, toe and under three metatarsal heads. Data from the sensors are transferred to a host computer via a Universal Serial Bus (USB) cable and saved to system memory. The system is capable of sampling data up to 240Hz across 5 active data acquisition channels. Software uses the data to display the loading profile for each sensor in order to provide quantitative results of cumulative plantar pressure. The history of each sensor can be acquired to examine event related alterations, such as endurance sport events or pre and post surgical procedures. The system is designed with the capability to supply the data necessary for characterization of such alterations.
