本文介绍了一种运动协同作用的方法，使他们能够量化的人在运动或实践中的非典型运动模式。在这种方法中，运动变异性可以相对于任务特定的性能变量被分类为“好”（不影响变量）或“坏”（改变变量）。作者回顾了具有典型运动模式的人、唐氏综合征患者、中风后患者和老年人的运动协同作用研究。练习对运动协同作用的两个阶段的影响被描述为以协同指数的不同变化为特征：指数先增加，然后下降。协同变化与实践可能伴随着塑料的变化，从初级皮质和半球间的投射下降的预测。作者强调的重要性，在运动障碍和康复领域的从业者-意识到在运动控制和协调的最新进展。
This article describes an approach to motor synergies that allows them to be quantified in people with atypical movement patterns during exercise or practice. Within this approach, motor variability may be classified with respect to a task-specific performance variable as "good" (not affecting the variable) or "bad" (changing the variable). The authors review studies of motor synergies in people with typical movement patterns, in people with Down syndrome, in patients after stroke, and in elderly people. Two stages of practice effects on motor synergies are described as being characterized by different changes in the synergy index: an increase followed by a drop in the index. Synergy changes with practice may be accompanied by plastic changes in both descending projections from the primary cortex and interhemispheric projections. The authors emphasize the importance-for practitioners in the area of motor disorders and rehabilitation - of being aware of the latest progress in motor control and coordination.
