A mathematical modeling approach is applied for deriving subject-specific stabilometric parameters associated with center-of-pressure sway measurements for assessing balancing ability of subjects in quiet standing on a force platform. Based on the inverted pendulum model, a new combined stabilometric parameter including anthropometric characteristics (body height and mass) is obtained which represents a measure of postural instability. A physical meaning of the subject-specific parameter is related to the effective stiffness of the inverted pendulum model.
一种数学建模方法被应用于推导与压力中心摇摆测量相关的个体特异性稳定参数，以评估在力量平台上安静站立的个体的平衡能力。基于倒立摆模型，获得了一个新的组合稳定参数，包括人体测量特征（身高和体重），它代表了姿势不稳定性的一种度量。该个体特异性参数的物理意义与倒立摆模型的有效刚度有关。
