Control processes in fast movements end before the peak velocity: evidence based on experimental analysis and modelling

Both experimental effects of perturbations and computer simulation indicate that shifts in the equilibrium position underlying fast discrete movements of the elbow are completed before the peak velocity of movement and thus before the end of the phasic EMG activity. The authors' results imply t...

More Information
Summary:Both experimental effects of perturbations and computer simulation indicate that shifts in the equilibrium position underlying fast discrete movements of the elbow are completed before the peak velocity of movement and thus before the end of the phasic EMG activity. The authors' results imply that EMG patterns and the resulting kinematics are not preprogrammed but represent long-lasting dynamic responses of the system to this short-duration control pattern combined with the effects of load and peripheral feedback.< >
