Multibody Dynamic Simulation-Driven Analyses and Assessments of Gait Deviations For Individuals with Above Knee Prostheses
My research aims to improve the evaluation and, in the long term, the design of prosthetic devices for individuals with above-knee amputations. Currently, assessing how well a prosthetic knee works typically requires extensive testing with patients, which can be time-consuming and physically demanding. To address this, I am developing dynamic computer models that can simulate human gait with different movement patterns or force targets.
By comparing outputs from these different simulation models, I can identify how specific aspects of the prosthetic device or the patient's own adaptations affect walking patterns. This approach would allow for the optimization of prosthetic designs or the improvement of training strategies during rehabilitation without requiring repeated patient testing. Ultimately, this work could lead to improved mobility and quality of life for people who have lost a leg above the knee.
