FES-induced co-activation of antagonist muscles for upper limb control and disturbance rejection

Highlights • A neuromusculoskeletal model including proprioceptive feedback and anatomical data to study co-activation of antagonist muscles is proposed. • A simulation study to investigate FES-induced joint impedance modulation indicates both stiffness and damping may be increased. • A closed-loop...

Description
Summary:Highlights • A neuromusculoskeletal model including proprioceptive feedback and anatomical data to study co-activation of antagonist muscles is proposed. • A simulation study to investigate FES-induced joint impedance modulation indicates both stiffness and damping may be increased. • A closed-loop control strategy integrating FES-controlled co-activation is proposed. • Preliminary experimental results on four healthy subjects indicate joint stiffness is greatly increased and closed-loop control may present functional performance.
