Abstract :
A parallel-cascade system identification method was used to identify the modulation of intrinsic contributions to dynamic ankle stiffness at 15 discrete positions throughout the subject´s range of motion (ROM). Intrinsic stiffness dynamics were well described by a linear, second-order system between position and torque. Measurements were taken before and after to evaluate the effects of proprioceptive neuromuscular facilitative (PNF) stretching on the tibilias anterior and triceps surae muscles. A single PNF stretching session with warm-up was found to have little effect on intrinsic ankle joint dynamics
