Neuromotor development of preterm and full-term infants.
The Neuromotor Behavioral Inventory (NBI), a 16-category measure of muscle tone, developmental motor abilities, quality of movement, neurological reflexes and reactions, and neuromotor outcome was used with 38 infants divided into three groups: healthy preterm (HPT), sick preterm (SPT), and healthy full-term (HFT) infants. Infants were tested at five time points: 40 weeks postconception (newborn) and 3, 6, 9 and 12 months of age post-term. The intent of the study was two-fold: to determine whether there are developmental differences among the groups of infants and whether the differences persist during the first year of life. Results indicate that HFT and HPT infants score higher than SPT infants in the neuromotor categories of: muscle tone, upper extremity development, head control, and neuromotor outcome rating. HFT infants scored higher than both preterm groups in: trunk rotation, reaction to movement, visual and auditory attention, and fixing. Differences persisted among the groups during the first year of life in the following: the developmental motor ability of trunk rotation, fixing, adaptability, and the neuromotor outcome rating. It appears that neonatal health status is a contributing factor to infant neuromotor development, particularly in the quality of movement reactions.
