摘要：

During quiet standing, the human body continually moves about in an erratic, and possibly chaotic, fashion. Here we show that postural sway is indistinguishable from correlated noise and that it can be modeled as a system of bounded, correlated random walks. These novel results suggest that the postural control system incorporates both open-loop and closed-loop control mechanisms.
