Baropodometry is a method of diagnostic that enables the analysis of the biomechanical characteristics of the feet by analyzing graphical records of plantar footprints. Appropriate patient treatment of dysfunctions of the feet at early stages may prevent a series of different kinds of pain and problems associated with feet, knee, hip, and spine or back, which may be causing pain, fatigue, frustration and inability to move properly. Given these considerations, a low cost baropodometric system for assessing dysfunctions of the feet and postural deviations in children has been developed in this work. The system consists of a pair of instrumented shoe insoles, a data acquisition board connected to the templates and a Bluetooth device for sending signals to a computer for processing. The system has been tested with children of both genders, anomalies in patients with gait problems have been highlighted by the system and a medical specialist in pediatric physiotherapy has successfully evaluated the results.
