Insights
Preterm infants develop early postural control sequentially, like full-term infants. However, preterm infants show a slower onset of extensor/flexor patterns and less mature load-bearing distribution for motor skill acquisition.
Area of Science:
- Developmental Pediatrics
- Motor Control Research
- Neonatal Development
Background:
- Early postural control is crucial for motor development in infants.
- Understanding developmental trajectories in preterm infants is essential for early intervention.
Purpose of the Study:
- To compare the development of early postural control in preterm and full-term infants.
- To identify specific motor acquisition differences between these groups.
Main Methods:
- Prospective observational study design.
- Inclusion of 10 preterm (32-36 weeks gestation) and 10 full-term infants.
- Observations conducted on day 15, and at 1, 2, and 3 months post-birth.
Main Results:
- Both preterm and full-term infants demonstrate sequential development of early postural control.
- Preterm infants exhibited a delayed onset in acquiring extensor and flexor postural patterns.
- Load-bearing distribution was observed to be less mature in preterm infants compared to full-term peers.
Conclusions:
- Early postural control development follows a similar sequential pattern in both preterm and full-term infants.
- Preterm infants display distinct developmental trends in specific motor components, including slower acquisition of postural patterns and less mature load bearing.
- These findings highlight potential areas for targeted developmental support in preterm infants.
Abstract:
In a prospective study, 10 infants born between 32 to 36 weeks of gestation and 10 infants born at fullterm were observed on day 15, and in months 1, 2 and 3. The investigation showed that the development of early postural control takes place in a sequential way in preterm infants, similar to that of in fullterm infants. However, some movement components for the acquisition of motor abilities showed a different trend in the development of preterm infants when compared to fullterm infants: the onset for the acquisition of the extensor and flexor patterns was slower and the distribution of the load bearing was less mature.
