This group focuses on the development of mathematical models for representing human motions, to potentially benefit patients undertaking a physical rehabilitation therapy (e.g., following a stroke, or due to other medical conditions). The research employs deep neural networks for modeling human motions at multiple hierarchical levels of abstraction. The aim is to encode the movements of a patient in performing physical exercises into a set of trajectory features and use the features for automated evaluation of the patient’s performance.
The group developed a deep learning framework for assessment of rehabilitation exercises, as well as the team created a dataset of physical rehabilitations exercises. The current focus of the improving and evaluating the proposed deep learning models.
We submitted an NIH R01 grant application in July 2022, but our application was not funded. Our plan is to revise the application and re-apply in the second half of 2023.
