Min. activation in damped equilibrium model

[William A]

Hi,

I understand that minimum activation in Millard equilibrium muscle model should be nonzero, but what about the damped equilibrium model? Can we have zero muscle activation in the damped version?

Thanks,
William

Can we have zero muscle activation in the damped version?

Yes. Please see the following resources:
