在安静站立期间，人体以随机方式摇摆。在这里，我们表明，波动耗散定理可以应用于人体姿势控制系统。也就是说，姿势系统对弱机械扰动的动态响应可以从准静态条件下系统所表现出的波动来预测。我们还表明，估计的相关性和响应函数可以描述由一个简单的随机模型组成的钉扎聚合物。这些发现表明，姿势控制系统利用相同的控制机制下安静站立和动态条件。[S0031-9007（97）05009-6]
During quiet standing, the human body sways in a stochastic manner. Here we show that the fluctuation-dissipation theorem can be applied to the human postural control system. That is, the dynamic response of the postural system to a weak mechanical perturbation can be predicted from the fluctuations exhibited by the system under quasistatic conditions. We also show that the estimated correlation and response functions can be described by a simple stochastic model consisting of a pinned polymer. These findings suggest that the postural control system utilizes the same control mechanisms under quiet-standing and dynamic conditions. [S0031-9007(97)05009-6]
