The recent developments of a particular approach to analyzing motor synergies based on the principle of motor abundance has allowed a quantitative assessment of multi-effector coordination in motor tasks involving anticipatory adjustments to self-triggered postural perturbations and in voluntary postural sway. This approach, the uncontrolled manifold (UCM) hypothesis, is based on an assumption that the central nervous system organizes covariation of elemental variables to stabilize important performance variables in a task-specific manner. In particular, this approach has been used to demonstrate and to assess the emergence of synergies and their modification with motor practice in typical persons and persons with Down syndrome. The framework of the UCM hypothesis allows the formulation of testable hypotheses with respect to developing postural synergies in typically and atypically developing persons.
基于运动丰富性原理的一种分析运动协同作用的特定方法的最新进展，使得对涉及对自我引发的姿势扰动进行预期调整的运动任务以及自愿姿势摆动中的多效应器协调进行定量评估成为可能。这种方法，即非受控流形（UCM）假说，基于这样一种假设：中枢神经系统以任务特定的方式组织元素变量的协变，以稳定重要的性能变量。特别是，这种方法已被用于证明和评估典型人群和唐氏综合征患者中协同作用的出现及其随运动练习的变化。UCM假说的框架允许针对典型和非典型发育人群中姿势协同作用的发展提出可检验的假设。
