Quality of motor performance in preterm and full-term 3-year-old children.

Background: A combined assessment of motor performance and behaviour (CAMPB) was introduced previously for use in a longitudinal study of children who needed neonatal intensive care (NIC) and were born very preterm (n = 68), moderately preterm (n = 81) and full-term (n = 77) and in a reference group of neonatally healthy full-term children (n = 72). Aim To follow up the quality of motor performance at 3 years of age in the above groups of children.

Method: A detailed assessment of motor performance and an assessment of co-ordination were performed according to the CAMPB protocol. The results were compared between the different groups of children, and the relation between the two ways of assessing quality of motor performance was examined.

Results: The detailed assessment showed that the very preterm children had a significantly higher total score of deviations than any of the other gestational age groups of children. Also, some types of deviations were much more frequently observed in the very preterm children than in the other three groups. Some types of deviations were more often seen in children with pronounced incoordination than in children with no incoordination. The results from the two ways of assessing motor performance were strongly correlated.

Conclusion: At 3 years of age, NIC children born very preterm have a lower quality of motor performance than NIC children born at a higher gestational age and healthy children born at term. The two ways of assessing quality of motor performance proved useful in identifying children with deviations indicating minor motor impairments.
