Applied Research on Quantitative Method of Motor Coordination Basing on Functional Data Analysis Technique

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.
