Systematic Variation of Prosthetic Foot Spring Affects Center-of-Mass Mechanics and Metabolic Cost During Walking

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
