Insights

Early motor assessments in extremely preterm infants can predict later neurodevelopmental outcomes. Poorer scores on the Motor Optimality Score-Revised (MOS-R) and abnormal General Movements Assessment (GMA) at 14 weeks corrected age are linked to cerebral palsy and developmental delays at two years.

Area of Science:

  • Neonatal neurology
  • Developmental pediatrics
  • Movement science

Background:

  • Infants born extremely preterm (<28 weeks' gestation) or extremely-low-birthweight (ELBW) (<1000g) are at high risk for neurodevelopmental impairments.
  • Early identification of neurodevelopmental risks is crucial for timely intervention.

Purpose of the Study:

  • To investigate the relationship between early motor repertoire and neurodevelopmental outcomes at two years in extremely preterm/ELBW infants.
  • To assess the predictive value of the General Movements Assessment (GMA) and Motor Optimality Score-Revised (MOS-R) for neurodevelopmental outcomes.

Main Methods:

  • A prospective cohort study of 139 extremely preterm/ELBW infants was conducted.
  • Parent-recorded videos were used to score the GMA and MOS-R at 12-13 and 14-15 weeks corrected age.
  • Neurodevelopmental outcomes at two years included cerebral palsy diagnosis and scores on the Bayley Scales of Infant and Toddler Development.

Main Results:

  • Higher MOS-R scores at 14-15 weeks corrected age were associated with lower odds of cerebral palsy (CP) and motor or cognitive impairment at two years.
  • Absent or abnormal GMA at 14-15 weeks corrected age predicted CP and motor delay.
  • Early MOS-R scores (12-13 weeks) showed limited association with two-year neurodevelopmental outcomes.

Conclusions:

  • Motor repertoire assessments, specifically MOS-R and GMA, at 14-15 weeks corrected age are valuable predictors of neurodevelopmental outcomes in extremely preterm/ELBW infants.
  • These findings support the use of early motor assessments for identifying infants at risk for CP and developmental impairments.

Language Development

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

Piaget's Stage 1 of Cognitive Development

The sensorimotor stage, the initial phase of Jean Piaget's theory of cognitive development, spans the first two years of a child's life. During this period, infants actively engage with their surroundings, building cognitive awareness through direct interaction with the world. This interaction is primarily based on sensory perception and motor actions, allowing infants to gradually understand basic physical properties and predict how objects interact within their environment.

Socioemotional Development during Infancy

Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.
