Previous studies of the human stretch reflex have been limited by difficulties separating the reflex response from those due to passive and intrinsic joint properties. This study has presented and experimentally verified a method for separately determining these contributions to the human ankle response, and used this technique to assess the reflex contribution to joint dynamics during the application of a stochastic position perturbation. Although this method was applied to the human ankle, it is readily applicable to any intact joint. / The results of this analysis showed that most of the neuromuscular response could be accounted for by two parallel pathways: one for the stretch reflex dynamics, and another for the intrinsic joint stiffness. The estimated nonparametric model accounted for 92% of the measured torque variance between 0.5-25Hz, and greater than 94% of the variance between 5-12Hz, where the stretch reflex was found to be most effective.
