Abstract [en]

A preterm birth is associated with neurodevelopmental impairment risks that may affect motor function. As research in the area of neuromotorical development/deviations is limited, further knowledge is required in order to improve the premises for premature children’s motor development. This because motor functions is an imperative part of both learning and social life. The main purpose of this study was to examine differences and associations regarding brain volume and motor functions in 18 children born preterm, in comparison to 19 children born at term. An additional objective was to examine associations between brain volumes, gestational age and birth weight in preterm children. Motor functions and brain volumes were examined in a group of 7-8 year old children. Motor functions were assessed in regards of manual dexterity, balance and aiming and catching. Children born at term displayed a higher level of motor function than those born preterm.  No evident differences were found regarding total brain volume. High scores of manual dexterity was significantly positively correlated with higher birth weight and larger amount of myelinated brain substance. A high score of balance was associated with higher volumes of several brain structures and lower relative frequency of grey matter. In this study no apparent differences were found between the groups in regards of brain size. However, the group of premature children performed on a significantly lower level motorically.
