Insights
Premature infants born at lower gestational ages (GA) show poorer global motor and sensory oral motor development. Lower GA is linked to increased risks and delayed development in preterm infants.
Area of Science:
- Neonatal development
- Pediatric motor control
- Infant sensory processing
Context:
- Preterm infants require specialized developmental assessments.
- Gestational age (GA) is a critical factor in infant development.
- Early identification of developmental delays is crucial for intervention.
Purpose:
- To evaluate the association between gestational age (GA) and global motor development in preterm infants.
- To assess the link between GA and early signs of sensory oral motor development delay.
- To investigate potential associations between global motor and sensory oral motor development.
Summary:
- Lower GA (29-34 weeks) correlated with higher risk signs in sensory oral motor development compared to higher GA (35-36 weeks).
- Infants with lower GA showed significantly more global motor scores below the 10th percentile on the Alberta Infant Motor Scale (AIMS).
- Higher risk signs in sensory oral motor development were observed in infants with lower AIMS scores.
Impact:
- Gestational age significantly impacts both sensory oral motor and global motor development in preterm infants.
- Findings suggest preterm infants with lower GA are at higher risk for developmental delays.
- This study highlights a potential link between sensory oral motor and global motor development in this population.
Background:
development assessment of preterm infants.
Aim:
to evaluate the association between the gestational ages (GA) of premature infants with the global motor development as well as with early signs of sensory oral motor development delay, and to verify a possible association between them.
Method:
an exploratory study that assessed the development of 55 infants with corrected chronological ages between four to five months, born preterm at the Instituto Materno Infantil Professor Fernando Figueira (IMIP) and who were followed at the Kangaroo Mother Program Clinic between March and August of 2004. The assessment of the sensory oral motor development was performed through pre-selected indicators and of the global motor development through the Alberta Infant Motor Scale (AIMS).
Results:
infants with lower GA (29 to 34 weeks) presented a higher median of risk signs in the sensory oral motor development assessment when compared to those with higher GA (35 to 36 weeks). Regarding the global motor development, infants born with lower GA presented a higher number of scores in the AIMS below percentile 10 (26%) when compared to those with a higher GA (4%) (p=0.009). The median index of the risk signs for the sensory oral motor development were significantly higher among infants with total AIMS scores below percentile 25 when compared to those with scores equal to or above percentile 25.
Conclusion:
the gestational age of infants at birth influenced the sensory oral motor and global motor development - infants with lower gestational ages presented worse performances. These findings suggest a possible association between both aspects of infant development.
