当站立时，老年人与年轻人相比表现出不同的运动行为。然而，这些差异的原因仍然很清楚。本研究的目的是验证一个假设，即只有感觉噪音和刚度的大小可以重复地确定髋关节或踝关节运动策略的趋势。对三种噪声条件和三种刚度条件下的肌肉骨骼模型的姿势控制进行了仿真。髋关节和踝关节角度的变化表明，感觉噪声幅度对选择没有影响。而随着刚度的增加，踝关节策略更倾向于选择。老年人的策略转移可能来源于其他成分;肌肉无力，神经时间延迟增加，或基于其他评估指标的学习。
While standing, the elderly exhibit different move- ment behaviors compared to young people. However, the causes of these differences remain clear. The purpose of this study was to verify a hypothesis that only the magnitude of sensory noise and stiffness can reproducibly determine trends in the hip or ankle movement strategies. Simulations of postural control of a musculoskeletal model for three noise conditions and three stiffness conditions were performed. Variations in the angles of the hip and ankle suggested that the sensory noise amplitude had no influence on the selection. However, the ankle strategy tended to be selected with the increase of stiffness. Strategy shifts of elderly may be derived from other components; muscle weakness, increase of neurological time delay, or learning based on other evaluation index.
