人类在站立时会产生非常缓慢(1赫兹)的身体摇摆，这种摇摆的行为被认为是根据神经性共济失调的特点而改变的。为了探讨神经性共济失调的摇摆机制和这种摇摆行为的机制，本研究提出了一种双足站立的大鼠实验环境。通过实验，我们成功地测量了6只完整的大鼠在没有姿势支撑的情况下站立超过200秒。此外，通过将测量的压力中心(COP)和系统模型的COP与提出的人体站立模型的非线性PID控制模型进行比较，对大鼠的控制参数进行了数值计算。评估的大鼠控制参数与人接近，即控制策略被认为与人相似。
Human generates very slow (<;1 Hz) body sway during standing, and the behavior of this sway is known to be changed characteristically depending on the neural ataxia. In order to investigate the sway mechanism and mechanism of neural ataxia through this sway behavior, the present research proposes an experimental environment of rats under bipedal standing. By the experiment, we succeeded the measurement of six intact rats standing for over 200 seconds without postural supports. Moreover, by comparing measured center of pressure (COP) and that of system model with nonlinear PID control model which is proposed as human standing model, control parameters of rats were numerically evaluated. Evaluated control parameters of rats were close to those of human, i.e., control strategy was considered to be comparable between rats and human.
