We investigate the adoption of natural co-activation strategies as present in antagonistic muscle pairs aiming to improve motor precision produced by FES. In a test in which artificial knee-joint movements were generated, we could improve the smoothness of FES-induced motion by 513% when applying co-activation during the phases in which torque production is switched between muscles – compared to no co-activation. We further demonstrated how the co-activation level influences the joint stiffness in a pendulum test.en570 Biowissenschaften; Biologie600 Technik, Technologieantagonistic muscle pairsco-activationFunctional Electrical StimulationneuroprostheticsFESArticle2364-5504
