The neuromechanical properties of a joint can be described in terms of its dynamic stiffness that describes the dynamic relation between joint position and torque. Dynamic stiffness is generated by intrinsic (mechanical) and reflex (neural) mechanisms that act and change together; therefore, their individual contributions cannot be measured directly. During stationary conditions, the neuromechanical properties of a joint can be estimated using nonlinear mathematical models, specialized systems identification algorithms, and disturbance experiments. Stationary results have shown that dynamic joint stiffness is heavily modulated by joint position and voluntary torque. Consequently, during movement, when these undergo large, rapid changes, dyn...
