Treadmill stepping in infants born prematurely
Early Human Development
|November 18, 1994
Summary
Low-risk premature infants demonstrate coordinated stepping on a treadmill as early as one month corrected age, outperforming full-term infants. This suggests early out-of-utero experience may enhance neuromotor development.
Area of Science:
- Developmental Pediatrics
- Neurorehabilitation
- Motor Control
Background:
- Premature birth can impact infant motor development.
- Understanding early neuromotor pathways in premature infants is crucial for timely interventions.
- Treadmill-based assessments offer insights into infant locomotion.
Purpose of the Study:
- To investigate the stepping abilities of low-risk premature infants on a treadmill.
- To compare the motor coordination of premature infants with full-term infants.
- To assess the influence of corrected age and treadmill speed on infant stepping patterns.
Main Methods:
- Twelve low-risk premature infants were observed at 1, 6, and 9 months corrected age.
- Infants performed five 20-second trials on a supported treadmill at three different speeds.
- Analysis included leg postures, limb movement parameters, and anthropometric measures from video recordings.
Main Results:
- Premature infants exhibited coordinated alternating steps responsive to speed changes at all observed ages.
- Compared to full-term peers, premature infants showed more coordinated steps.
- Premature infants displayed more extended leg postures during non-stepping phases than during initiated swings.
Conclusions:
- Low-risk premature birth does not appear to impede the neuromotor pathway for stepping.
- Early exposure to treadmill stepping may facilitate motor development in premature infants.
- These findings highlight the potential benefits of early motor interventions for preterm infants.
