We, Fenne, Mirthe and Jenny, are senior year physical therapy students at Zuyd University of Applied Sciences in Heerlen. For our bachelor thesis we are investigating the validity of an augmented feedback device that helps improve the walking pattern of people with acquired brain injury. Our study aims to assess whether the system is able to measure gait characteristics of people after stroke such as an irregular or slow walking pattern correctly. We are investigating first insights about the validity. The results of this study are expected June 2018.
