Concurrent Validity of Wearable Nanocomposite Strain Sensor with Two-Dimensional Goniometer and its Reliability for Monitoring Knee Active Range of Motion in Multiple Participants
Concurrent Validity of Wearable Nanocomposite Strain Sensor with Two-Dimensional Goniometer and its Reliability for Monitoring Knee Active Range of Motion in Multiple Participants 150 150 Transactions on Neural Systems and Rehabilitation Engineering (TNSRE)
The range of motion (ROM) of joints in the human body is essential for movement and functional performance. Real-time monitoring of joint angles is crucial for confirming pathologic biomechanics, providing… read more

Reducing Knee Joint Loads During Stance Phase With a Rigid-Soft Hybrid Exoskeleton
Reducing Knee Joint Loads During Stance Phase With a Rigid-Soft Hybrid Exoskeleton 150 150 Transactions on Neural Systems and Rehabilitation Engineering (TNSRE)
High mechanical loads generated during walking may accelerate the wear of the knee joint. General knee exoskeletons mainly reduce knee joint load by applying pure torque assistance to reduce the… read more
A Swing-Assist Controller for Enhancing Knee Flexion in a Semi-Powered Transfemoral Prosthesis

A Swing-Assist Controller for Enhancing Knee Flexion in a Semi-Powered Transfemoral Prosthesis
A Swing-Assist Controller for Enhancing Knee Flexion in a Semi-Powered Transfemoral Prosthesis 789 444 Transactions on Neural Systems and Rehabilitation Engineering (TNSRE)
This work proposes a new swing controller for semi-powered low impedance transfemoral prostheses that resolves the issue of potentially competing inputs between artificial assistive power and user-sourced power. Rather than… read more

A Gluteus-Specific Muscle Synergy Recruited During the First Recovery Step Following a Backward Pitch Perturbation
A Gluteus-Specific Muscle Synergy Recruited During the First Recovery Step Following a Backward Pitch Perturbation 150 150 Transactions on Neural Systems and Rehabilitation Engineering (TNSRE)
The central nervous system momentarily activates a set of specific muscle synergies to maintain balance when external mechanical perturbations induce walking instability, which is critically involved in preventing falls. The… read more

Lower Limb Torque Prediction for Sit-To-Walk Strategies Using Long Short-Term Memory Neural Networks
Lower Limb Torque Prediction for Sit-To-Walk Strategies Using Long Short-Term Memory Neural Networks 150 150 Transactions on Neural Systems and Rehabilitation Engineering (TNSRE)
Joint torque prediction is crucial when investigating biomechanics, evaluating treatments, and designing powered assistive devices. Controllers in assistive technology require reference torque trajectories to set the level of assistance for… read more

Controlling Powered Prosthesis Kinematics Over Continuous Inter-Leg Transitions Between Walking and Stair Ascent/Descent
Controlling Powered Prosthesis Kinematics Over Continuous Inter-Leg Transitions Between Walking and Stair Ascent/Descent 150 150 Transactions on Neural Systems and Rehabilitation Engineering (TNSRE)
Although powered prosthetic legs have enabled more biomimetic joint kinematics during steady-state activities like walking and stair climbing, transitions between these activities are usually handled by discretely switching controllers without… read more

Lower-Limb Myoelectric Calibration Postures for Transtibial Prostheses
Lower-Limb Myoelectric Calibration Postures for Transtibial Prostheses 150 150 Transactions on Neural Systems and Rehabilitation Engineering (TNSRE)
The use of an agonist-antagonist muscle pair for myoelectric control of a transtibial prosthesis requires normalizing the myoelectric signals and identifying their co-contraction signature. Extensive literature has explored the relationship… read more

Systematic Variation of Prosthetic Foot Spring Affects Center-of-Mass Mechanics and Metabolic Cost During Walking
Author(s)3: Karl E. Zelik, Steven H. Collins, Peter G. Adamczyk, Ava D. Segal, Glenn K. Klute, David C. Morgenroth, Michael E. Hahn, Michael S. Orendurff, Joseph M. Czerniecki, Arthur D. Kuo
Systematic Variation of Prosthetic Foot Spring Affects Center-of-Mass Mechanics and Metabolic Cost During Walking 1264 855 Transactions on Neural Systems and Rehabilitation Engineering (TNSRE)

Lower-limb amputees expend more energy to walk than non-amputees and have an elevated risk of secondary disabilities. Insufficient push-off by the prosthetic foot may be a contributing factor. We aimed…
