Abstract. This project proposes a tool to support the process of analysis and diagnosis of patients that of foot deformities.Basically, it is proposed to develop an computational system that monitor and evaluate the plantar pressure of patients. The system will determine the points of highest pressure made during a walking, and then to identify the king of footfall, instability, impulse and other biomechanical limitations. This way, we idealized the use of pressure-sensitive insoles along with data storage devices, whitch will allow to analysis and supportive diagnosis in the distribution of plantar pressure.
