研究运动生成的领域，包括机器人学，心理学，认知科学和神经科学，利用与生物系统中普遍存在的可变性相关的概念和工具。变异性的概念和用于评估这一概念的非线性动力学的措施打开了许多类型的运动功能障碍的研究新的前景。这篇综述介绍了在探索变异性及其在理解人类运动的潜在重要性的创新。远不是一个错误的来源，证据支持存在一个最佳状态的变化，健康和功能运动。这种变异性有一种特殊的组织，其特点是结构混乱。偏离这种状态会导致生物系统要么过于僵硬和机器人，要么嘈杂和不稳定。这两种情况都导致系统对扰动的适应性较差，例如与不健康的病理状态或缺乏技巧有关的扰动。
Fields studying movement generation, including robotics, psychology, cognitive science and neuroscience utilize concepts and tools related to the pervasiveness of variability in biological systems. The concept of variability and the measures for nonlinear dynamics used to evaluate this concept open new vistas for research in movement dysfunction of many types. This review describes innovations in the exploration of variability and their potential importance in understanding human movement. Far from being a source of error, evidence supports the presence of an optimal state of variability for healthy and functional movement. This variability has a particular organization and is characterized by a chaotic structure. Deviations from this state can lead to biological systems that are either overly rigid and robotic or noisy and unstable. Both situations result in systems that are less adaptable to perturbations, such as those associated with unhealthy pathological states or absence of skillfulness.
