【报告简介】
生物力学和运动控制的中心研究之一是揭示当外围系统涉及机械冗余时人体的运动是如何组织的。两种方法主导了解决这个问题的尝试。其中之一假设神经控制器选择优化（最大化或最小化）某一成本函数的元素的参与模式。由此，实现了对重要性能变量的单一求解，并根据优化过程组织了一组性能变量范围的单解集。另一种方法假定，稳定重要性能变量（协同）的控制器总是有助于解族。非控制流形（UCM）分析用于量化可降低性能变量变异性的元素变量的协变。最近发展起来的分析逆优化（ANIO）方法被用于基于一组实验观测值计算成本函数。一系列研究的主要目的是研究1)运动变异性与人类运动行为的最优性如何兼容，以及2)年龄相关的变化在多指按压任务中如何影响最优性与运动变异性之间的联系。目前的研究表明，对于不同的性能变量，可以使用优化原则来选择元素变量的组合和元素变量之间的平均共享，而协同作用规定在相同的性能下不同试验之间的手指力方差模式。变量的年轻受试者。老年受试者表现出较小的协同指数，对应于最优解平面与实验数据平面的较大偏差。这两个分析，在多个任务上的最佳性能和在一个任务上的试验上的力协变，可能反映与健康老化相关的一组单一过程。这一过程导致潜在的次优共享模式和较弱的协同效应。我们还测试了早期帕金森病患者手指相互作用和多指协同作用的变化。结果表明，在稳态和循环力产生任务中，多指协同作用较对照组弱。这些结果为利用运动协同试验早期检测PD和跟踪其进展和治疗效果提供了令人兴奋的机会。他们还建议，运动协同试验可用于神经系统患者协调功能受损的其他情况。
