Effects of a Powered Knee-Ankle Prosthesis on Amputee Hip Compensations: A Case Series

This dataset was originally collected to investigate the effects of a robotic prosthetic leg on amputee hip compensations during level-ground treadmill walking experiments. (T. Elery, S. Rezazadeh, E. Reznick, L. Gray, and R. Gregg, “Effects of a Powered Knee-Ankle Prosthesis on Amputee Hip Compensations: A Case Series,” IEEE Transactions on Neural Systems and Rehabilitation Engineering). The dataset specifically contains data relating to Vicon (human lower-limb kinematics and kinetics), EMG, and robotic prosthetic data from an experimental protocol approved by the Institutional Review Board at the University of Texas at Dallas. Three subjects each walked on a Bertec instrumented treadmill for approximately 60 seconds with their day-to-day passive prosthesis and the powered prosthesis at their self-selected slow, normal, and fast walking speeds, resulting in a total of 6 walking trials per subject. During each trial, a 10-camera Vicon motion capture system recorded leg kinematics, while force plates in the Bertec treadmill recorded ground reaction forces, and a Delsys Trigno EMG system recorded muscle activation. The collected data has been divided into strides, and is interpolated to contain 100 points per stride. Strides begin at heel contact. Gait kinetics have been normalized by user mass.
