Modeling the muscle response to functional electrical stimulation (FES) is an important step during model-based FES control system design. The Hammerstein structure is widely used in simulating this nonlinear biomechanical… read more

Multi-directional Ankle Impedance During Standing Postures
Author(s)3: 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
