Fig. 6. Changes in length–tension curves from one subject associated with
errors in estimation of model parameters, experimentally recorded ankle
passive torques and other torque calculations. (A–C) Changes in the
passive length tension curve due to 5% errors of each parameter. (D) Changes
in the passive length–tension curve after scaling up or down by 2% and
5% the initial experimentally recorded passive ankle torque. (E) Changes in
the length–tension curve after adding biases to the footplate torques
(of 5%) and the foot torque (of 25%). See List of symbols for definitions of
parameters.
