abstract="Abstract Quiet standing and walking are generally considered to be an automatic process regulated by sensory feedback. In our report &quot;Astasia without abasia due to peripheral neuropathy,&quot; which was published in 1994, we proposed that forced stepping in patients lacking the ankle torque is a compensatory motor control in order to maintain an upright posture. A statistical-biomechanics approach to the human postural control system has revealed open-loop (descending) control as well as closed-loop (feedback) control in quiet standing, and fractal dynamics in stride-to-stride fluctuations of walking. The descending control system of bipedal upright posture and gait may have a functional link to cognitive domains. Increasing dependence on the descending control system with aging may play a role in falls in elderly people.<p /> <p>Language: ja</p>",
