| Abstract: | Cerebral Palsy (CP), a prevalent neurodevelopmental disorder affecting motor function, often manifests with gait dysfunction. While passive rigid ankle foot orthoses (AFOs) are commonly used, their limitations prompt the exploration of innovative solutions. The inGAIT-AFO, developed within the inGAIT project, introduces a quasi-passive AFO with customizable ankle stiffness. This thesis centers on the creation of a portable sensor data framework to assess the inGAIT-AFO’s efficacy through the analysis of the gait of those using it. The goal was to provide a ready-to-use solution for clinical assessment, enhancing AFO development for children with CP. Two main versions of the framework were developed following a predefined set of requirements. The framework made use of force sensing resistors (FSRs) and encoders to respectively estimate push-off forces and measure ankle angles during gait. Both versions of the framework were technically validated against the requirements. A framework was developed that is sufficiently capable of measuring and estimating the required outcome measures meeting 87% of all requirements and 100% of all must-have requirements. |
