Mobile Gait Analysis System for Lower Limb Amputee High-Level Activity Rehabilitation

Abstract

The goal of this project is to develop a mobile gait analysis system (MGAS) for use on soldiers with lower limb prosthetics to improve prosthetic fit, alignment and training. This system involves detecting ground reaction forces and also sensing movement using inertial measurement units (IMUs) (accelerometers and gyroscopes). The Mobile Ground Reaction Force Sensor has been designed and the device housing and sensors have been fabricated. The "smart pylon" force/moment sensor has been through design iterations and tests. IMUs and algorithms have been tested and evaluated for the Orientation Module but are currently under development. An overall system architecture to bring all these modules together for data collection and clinical analysis has been established. A protocol for the testing and validation of the MGAS in the gait lab at Center for the Intrepid has been established and the IRB application submitted. In the following calendar year, tests of the system will determine the accuracy of the results. The data from these results will be used to further improve the system and provide meaningful "clinical data". This clinical data will improve the method in which clinicians personalize prosthetics and train patients while also improving clinical results.
