Accurate Real-Time Joint Torque Estimation for Dynamic Prediction of Human Locomotion

Accurate Real-Time Joint Torque Estimation for Dynamic Prediction of Human Locomotion
Accurate Real-Time Joint Torque Estimation for Dynamic Prediction of Human Locomotion 789 444 IEEE Transactions on Biomedical Engineering (TBME)
A real-time human torque estimator is proposed and evaluated across various walking conditions. This estimator consists of a neural network and a dynamical model and only requires kinematic measurements. read more

Teleoperation of an ankle-foot prosthesis with a wrist exoskeleton

Teleoperation of an ankle-foot prosthesis with a wrist exoskeleton 150 150 IEEE Transactions on Biomedical Engineering (TBME)
This work aims to mimic sensorimotor control pathways disrupted after amputation with a system that allows a user to teleoperate their ankle-foot prosthesis with a wrist exoskeleton while receiving augmented sensory feedback. We present a novel wrist exoskeleton design and two control strategies that dictate ankle prosthesis behavior based on wrist input. We validate all system components with benchtop testing and demonstrate that one individual with transtibial amputation can accurately command desired wrist trajectories while walking. Systems like this have the potential to provide insight into human motor control and improve functional gait metrics for people with lower-limb amputation. read more
