Abstract:This thesis discusses the embedded software implementation of a wearable body motion measuring device that is being developed to monitor and evaluate the recovery of patients after a Crucial ligament reconstruction surgery or Knee Osteoarthritis treatment. This development was performed at Gable Systems BV for a broader project titled "INSTANT", also involving Roessingh Research and Development, University of Twente, Saxion and Topvorm Twente. These measuring devices can be attached to the limbs of the patient to measure and accurately profile his/her movements. This data is invaluable for the physiotherapist to diagnose the patient properly and to monitor the recovery process. The Sensor Unit hardware comprises of a Ultra Wideband (UWB) transceiver and an Inertial Measurement Unit (IMU) along with the necessary control circuitry. The UWB modules on these sensor units can perform wireless ranging measurements with other modules in the vicinity and also communicate the data by exchanging UWB messages. The software should be capable of recording these measurements along with the data from the IMU and transmitting it to physiotherapist's control center. The user should be able to send commands to the on-body sensors to perform measurements and other routines.
