The early development of head control in preterm infants

Area of Science:

• Neonatal development
• Pediatric neurology
• Motor control research

Background:

• Head control is a critical developmental milestone in infants.
• Understanding the nuances of head control development in preterm infants is essential for early identification of potential motor delays.

Purpose of the Study:

• To longitudinally document head control development in preterm infants.
• To investigate the relationship between head control progression and muscle development.
• To identify early indicators of motor handicap in preterm infants.

Main Methods:

• Longitudinal study of 104 infants born between 25-33 weeks gestation.
• Standardized assessments of head control and motor development.
• Correlation analysis of developmental rates with muscle development and extra-uterine experience.

Main Results:

• Protective side head turning evolves with reduced spinal extension.
• Normal motor outcome correlated with caudo-cephalic muscle development (P < 0.001, r = 0.5).
• Infants with motor handicap exhibited persistent early movement patterns; preterm infants born <31 weeks showed advanced head control at 33-35 weeks post-menstrual age.

Conclusions:

• The spinal extension movement during side head turning is specific to preterm infants.
• Individual rates of preterm head control development can be assessed through standardized examinations.
• While group delays were observed in infants with later motor handicaps, these were not individually significant during the preterm period.
