Abstract

A new method was developed which uses the delay inherent in reflex activity to separate the reflex contribution at the human ankle from the non-reflex components of the dynamic response. With this approach, it was possible to partition the torque response to a stochastic input into linear, nonlinear, and reflexive components. It is shown that the nonlinear stiffness component of the model had little effect for this subject, but it had a larger influence in other subjects where the reflex response is smaller. It is also likely to be important during larger amplitude perturbations, where the joint dynamics become exceedingly nonlinear.
