Abstract: Postural body sway displacements for quiet standing subjects (measured with a new ultrasonic device) are reported. Two of the well-known strategies for balancing, namely ankle and hip movements, were probed. The data are modeled using a Fokker–Planck–Langevin stochastic theory. Both analytic and computer simulation techniques are employed. The Kramers transition rate for a fall is expressed as a function of experimental parameters. The root mean square velocity is especially important for determining the fall probability.
