Abstract

The use of prosthetics has gradually increased due to various diseases, and it is estimated that 35-40 million people are prosthetic/orthotic users, with the number estimated to increase to two billion by 2050. Mobility has been determined to be a strong predictor of quality of life. There are various ways to measure mobility and predict outcomes in lower-limb amputees (LLA), such as self-report and performance-based measures. However, these come with many limitations, showcasing the need for quantitative measures of gait parameters to allow for better development of prosthetic components. Motion analysis tools are expensive and time consuming, but an inexpensive, easy to use, open-source platform, OpenCap, has emerged. OpenCap has only been validated among able-bodied individuals, so it’s utility in estimating kinematics of LLA patients is unknown. This study analyzed the clinical utility of OpenCap for lower-limp amputee prosthetic user patients through a system-usability scale survey provided to clinicians. Additionally, the temporal-spatial parameters acquired from the video of each patient were compared to known temporal-spatial parameters of LLA patients. It was found that OpenCap does have potential clinical utility as it was able to provide accurate temporal-spatial measures, and the SUS scores identified its usability.
