Table 3 Muscle-tendon parameters in the calibrated NMS model
From: Functional symmetrization of neuromotor modules during locomotor development in human infants
Parameter | Interpretation |
|---|---|
c1 | First recursive coefficient for estimating past neural activation from muscle excitation |
c2 | Second recursive coefficient for estimating past neural activation from muscle excitation |
ShapeFactor | Nonlinear factor describing the transformation from neural activation to muscle activation |
ActivationScale | Scaling coefficient for muscle activation |
OptimalFibreLength | Fiber length at which maximum activation occurs |
PennationAngle | Pennation angle of the fiber at maximum activation |
TendonSlackLength | Tendon length when the tendon is slack (not under tension) |
MaxContractionVelocity | Maximum velocity at which a muscle fiber can contract |
MaxIsometricForce | Maximum force a muscle can generate during isometric contraction |
StrengthCoefficient | Multiplicative factor applied to max isometric force for muscles within the same group |
