A Low Cost Wireless System to Monitor Plantar Pressure using Insole Sensor: Feasibility Approach

摘要

Plantar pressure analysis is an important strategy applied in clinical, orthopaedics, sports and rehabilitation studies. In this context, this work describes the development and application of wireless system to monitor plantar pressure. This system is composed by a data acquisition module based on low cost electronic instrumentation, high resolution insole flexible pressure sensor and Java application for data real-time visualization. To verify the feasibility and effectiveness of the system, workbench tests were realized and a healthy subject performed pilot trials based on static and dynamic activities on the biomechanics platform. According to the preliminary results, this system is effective to show the interaction between the foot and floor in static and dynamic conditions, presenting a measurement range of pressure of 0-300kPa and rapid response, among other features. Thus, this system is a feasible tool for quick and practical mapping of plantar pressure.
