Towards Realistic Prosthetic Gait Simulations: Enhancing the Accuracy of OpenSim Analysis by Integrating the Transfemoral Prosthesis Model

Ryu, H., Hong, W., & Hur, P. (2023, August 28).

By: H. Ryu*, W. Hong n & P. Hur *

topics (OpenAlex): Prosthetics and Rehabilitation Robotics; Muscle activation and electromyography studies; Spinal Cord Injury Research
TL;DR: The model with prosthesis characteristics demonstrated a closer match to the actuator data, particularly during the stance phase, suggesting that it better reflects the dynamic features of a real powered prosthesis, but discrepancies were observed during the swing phase, highlighting the need for further refinements.

Piecewise Linear Labeling Method for Speed-Adaptability Enhancement in Human Gait Phase Estimation

Hong, W., Lee, J., & Hur, P. (2022, December 14). IEEE Transactions on Neural Systems and Rehabilitation Engineering.

By: W. Hong n, J. Lee  n & P. Hur  n

author keywords: Legged locomotion; Labeling; Training; Phase estimation; Thigh; Data models; Exoskeletons; Gait phase estimation; machine learning; labeling method; exoskeleton and prosthesis
topics (OpenAlex): Prosthetics and Rehabilitation Robotics; Muscle activation and electromyography studies; Gait Recognition and Analysis
TL;DR: A new labeling method is proposed to have the estimator learn the ground truth based on variable toe-off onset at different walking speeds to improve speed-adaptability in gait phase estimation, resulting in outstanding accuracy for both gaitphase, heel-strike, and toe-offs estimation.
