Insights

Preterm infants aged 1-12 months demonstrate lower motor development scores compared to norms. This study provides a reference curve for motor skills in these infants.

Area of Science:

  • Pediatrics
  • Developmental Pediatrics
  • Neonatology

Background:

  • Preterm infants and those with low birth weight often experience developmental delays.
  • Establishing normative data is crucial for early identification and intervention.

Purpose of the Study:

  • To establish a reference curve for motor development in preterm infants up to 12 months corrected age.
  • To compare motor development trajectories of preterm infants with a standardized sample.

Main Methods:

  • Cross-sectional study involving 308 preterm infants (<2500g birth weight).
  • Utilized the Alberta Infant Motor Scale (AIMS) for motor development assessment.
  • Compared motor scores of preterm infants against the AIMS normative sample.

Main Results:

  • Preterm infants consistently scored lower on the AIMS than the normative sample from 1 to 12 months corrected age.
  • Motor skills showed a continuous increase in preterm infants over the first year.
  • Motor acquisition patterns exhibited a nonlinear trend with stabilization between 8 and 10 months.

Conclusions:

  • Preterm infants aged 1-12 months exhibit delayed motor development compared to normative standards.
  • The derived motor development curve can serve as a reference for follow-up programs, particularly in developing countries.

Piaget's Stage 1 of Cognitive Development01:14

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.

Hierarchy of Motor Control01:18

Hierarchy of Motor Control

The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.
Direct Motor Pathways01:11

Direct Motor Pathways

The direct motor pathways, also known as the pyramidal tracts, are a group of neural pathways that originate in the brain and descend through the spinal cord. They control the voluntary movement of the body. There are two major direct motor pathways: the corticospinal and the corticobulbar tracts.
The corticospinal tract is responsible for the voluntary movement of the limbs and trunk. It originates in the cerebral cortex of the brain and descends through the cerebrum's internal capsule and the...
Language Development01:22

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...
Indirect Motor Pathways01:22

Indirect Motor Pathways

The indirect motor or extrapyramidal pathways originate in the brainstem, the lower portion of the brain that connects it to the spinal cord. They consist of several distinct tracts, each with specialized functions. The four main tracts of the indirect motor pathways are the vestibulospinal tract, the reticulospinal tract, the tectospinal tract, and the rubrospinal tract.
The vestibulospinal tract originates in the vestibular nuclei of the brainstem. The vestibular system detects changes in...
Introduction to Developmental Psychology01:27

Introduction to Developmental Psychology

Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.Developmental MilestonesA key concept in developmental psychology is...
