站立是老年人日常活动的基础。要提高运动功能，既要增强肌肉力量，又要加强肌肉协调性。在本文中，我们提取重要的数据，肌肉协调，称为协同作用，执行站立运动的年轻人和老年人参与者。肌肉协同对身体运动学的贡献是通过估计关节扭矩和身体运动学的神经网络来计算的。为了解释老年人的运动功能缺陷，提取的协同作用被分为4个集群的基础上协同作用如何有助于身体运动学。聚类分析显示，长者在弯腰产生动力方面的协同作用较年青人为弱。与年轻人相比，老年人需要额外的肌肉协调来稳定站立后的姿势，以避免跌倒。
Standing up is fundamental to daily activities of the elderly. It is necessary both to enhance muscle strength and to strengthen muscle coordination for improvement of their motor function. In this paper, we extract important data related to muscle coordination, called synergy, to perform standing motion by young and elderly participants. The contribution of muscle synergy to body kinematics is calculated through neural networks that estimate joint torque and body kinematics. To explain deficient motor function in elderly persons, extracted synergy is classified into 4 clusters based on how synergy contribute to body kinematics. Cluster analysis explains that elderly participants have weaker synergy than young persons in bending their backs to generate momentum. Compared to younger persons, older persons require additional muscle coordination to stabilize posture after standing-up in order to avoid falling.
