Author(s): 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…

Multi-directional Ankle Impedance During Standing Postures

Author(s): Guilherme A. Ribeiro, Lauren N. Knop, Mo Rastgaar
Multi-directional Ankle Impedance During Standing Postures 592 1000 Transactions on Neural Systems and Rehabilitation Engineering (TNSRE)
In this study, we estimated the multi-directional ankle mechanical impedance in two degrees-of-freedom (DOF) during standing, and determined how the stiffness, damping, and inertia vary with ankle angle and ankle torque at different postures. read more

Energy-Optimal Human Walking With Feedback-Controlled Robotic Prostheses: A Computational Study

Author(s): Matthew L. Handford, Manoj Srinivasan
Energy-Optimal Human Walking With Feedback-Controlled Robotic Prostheses: A Computational Study 500 250 Transactions on Neural Systems and Rehabilitation Engineering (TNSRE)

  Lower-limb amputees typically experience reduced mobility and higher metabolic rates than non-amputees. It may be possible to improve their mobility and metabolic rate with an optimized robotic prosthesis. Here,…
