| 摘 要： | 对运动协调的研究是运动控制学科的重要组成部分,其主要目的在于探索中枢神经系统等元素对机体运动控制的作用及其机制。基于运动协调的概念,矩阵分解方法被长期应用于运动协调的量化中。然而,一些量化运动协调常用的矩阵分解方法中存在的问题也日益显露。在这些矩阵分解方法中,将运动自由度表示为一个向量,作为一个具有间断特征的数据集合进行处理,是不符合实际的。这使与中枢神经运动指令有关的参数也具有间断属性,与实际由其激活的具有连续性的运动自由度状态是有矛盾的。此外,它们的量化结果与一些运动协调相关的概念不相匹配,或者是未能展现出更加丰富的运动协调相关信息。这些对量化结果的理论解释有一定程度的影响。在这此运动协调的量化问题上,函数型主成分分析技术具有特有的优势。 |

| Abstract: | The research of motor coordination is an important part in the field of motor control,which has the purpose to explore the factors and mechanism of Multi-Degree-of-Freedom(DOF) System’s control.Base on existing theories,matrix factorization algorithms are used to quantify the concepts of motor coordination for long time.However,the defect of those methods of quantifying motor coordination has emerged.Viewing the movement of Degree-of-Freedom as vector,the data collection with a characteristic of interval,in these methods is not in accord with reality.It is also paradoxical that the interval output of central nervous system’s command generates the coherent DOF movement in reality.Therefore,the results of those quantitative methods are disaccording with few concepts of motor coordination,or can’t show some in formations of motor coordination.It would influence the interpretation of those results.Function principle component method has a peculiar function to deal with those problems of quantifying motor coordination. |
