Relations between handedness and motor abilities in preschool children

Relations between laterality and motor abilities were assessed in preschool children. Study sample included 202 children aged 5-7.5 decimal years. Upper extremity usage and gesture laterality was assessed by a battery of tests and used on children evaluation according to harmonious or inharmonious laterality. The performance of motor tasks that require whole body coordination, the speed of alternating hand motion frequency and the precision of hand aiming were assessed according to the type of laterality. There were no statistically significant sex differences in laterality distribution, and no differences according to laterality harmonization. There was no statistically significant difference in motor test performance between the children with harmonious and inharmonious laterality.
