Unobtrusive sensing for gait rehabilitation assessment

Abstract

A set of sensing devices that wireless transmit information on gait rehabilitation are presented. Aiming an objective evaluation of patient progress during physiotherapy sessions, we implemented a set of sensing devices that are wearable, such as a smart inertial measurement unit (IMU), or are embedded in walking aids, such as a microwave Doppler radar array. The data delivered by the smart sensing units designed for gait rehabilitation purpose are wireless transmitted to an advanced processing server that provides synthetic information to the physiotherapist that use a mobile device to access the available services. Elements of IMU sensor network and smart walker design and implementation for gait assessment, and the experimental results are included in the paper.
