Neuromotor and sensory development in preterm infants: prospective study

Area of Science:

• Neonatal Development
• Pediatric Neurology
• Developmental Psychology

Background:

• Preterm infants face significant developmental challenges.
• Early motor and sensory development are critical for long-term health outcomes.
• Understanding the interplay between motor and sensory skills in early infancy is essential.

Purpose of the Study:

• To examine the relationship between motor and sensory development in preterm infants.
• To assess developmental trajectories in the first four months of life.
• To identify risks in motor and sensory domains for infants born at 32 weeks gestational age or less.

Main Methods:

• A cohort of 56 high-risk preterm infants (born ≤32 weeks gestational age) was studied.
• Neuro Sensory Motor Developmental Assessment and Infant Sensory Profile-2 were administered at 1 and 4 months corrected age.
• Statistical analysis included Wilcoxon and Spearman's correlation tests.

Main Results:

• A significant difference in motor and sensory scores was observed between 1 and 4 months.
• High percentages of infants (86-91% at 1 month, 69-85% at 4 months) exhibited sensory development risks.
• A moderate to strong significant relationship was found between motor and sensory development.

Conclusions:

• Preterm infants are at considerable risk for both motor and sensory developmental delays.
• Early sensory-based intervention strategies warrant investigation for preterm populations.
• Longitudinal monitoring and targeted interventions are recommended for optimizing preterm infant development.
