Motor coordination of children: construction of centiles charts with LMS method by Cole and Green

Abstract

The purposes of this study were 1) to construct reference values to KTK test battery; 2) to compare Vouzela childrens motor coordination with those from other Portuguese sites and international references; 3) to present pseudo-velocity curves for each KTK test. The sample comprises 811 children aged six to 11 years. Motor coordination was assessed with the four tests of the KTK Battery. Centile charts were constructed using the LMS method implemented in LMSchartmarker Pro software. Pervasive interindividual differences were noted in all coordination tests. Mean values of Vouzela childrens motor coordination were lower than German and Belgian samples. 50th percentile was similar among Vouzela, Peruvian and Azorean samples. Pseudo-velocity curves suggested a marked specificity to each test and sex, as well as decreasing of the coordinative gains per year.
