Neuromotor development of preterm and full-term infants

Area of Science:

• Pediatrics
• Neurodevelopmental Pediatrics
• Infant Motor Development

Background:

• Infant neuromotor development is crucial for long-term health and function.
• Preterm birth and neonatal health status can influence developmental trajectories.
• The Neuromotor Behavioral Inventory (NBI) assesses various aspects of infant neuromotor function.

Purpose of the Study:

• To investigate developmental differences in neuromotor outcomes among healthy full-term (HFT), healthy preterm (HPT), and sick preterm (SPT) infants.
• To determine if these neuromotor differences persist throughout the first year of life.
• To identify specific neuromotor domains affected by neonatal health status.

Main Methods:

• Utilized the 16-category Neuromotor Behavioral Inventory (NBI) for assessment.
• Recruited 38 infants across three groups: HFT, HPT, and SPT.
• Assessed infants at five time points: newborn (40 weeks postconception) and 3, 6, 9, and 12 months post-term.

Main Results:

• SPT infants scored lower than HFT and HPT infants in muscle tone, upper extremity development, head control, and neuromotor outcome.
• HFT infants outperformed both preterm groups in trunk rotation, reaction to movement, visual/auditory attention, and fixing.
• Persistent differences were observed in trunk rotation, fixing, adaptability, and neuromotor outcome rating throughout the first year.

Conclusions:

• Neonatal health status is a significant factor in infant neuromotor development.
• Quality of movement reactions appears particularly sensitive to neonatal health.
• Early identification and intervention may be beneficial for infants at risk for neuromotor delays.
