Determination of characteristic parameters of human postural dynamics

Acta Otolaryngol Suppl. 1989;468:221-5. doi: 10.3109/00016488909139050.


Posture control performance was quantified in three variables (swiftness, stiffness, damping). Subjects were tested with a force platform recording body sway induced by vibrators attached to the calf muscles. Parameter estimation was made with identification of a transfer function representing the stabilized inverted pendulum. It is conjectured that the state feedback parameters identified are suitable for use in assessing ability to maintain posture.
