Insights

General movements (GM) in infants evolve from

Area of Science:

  • Neuroscience
  • Developmental Pediatrics
  • Movement Science

Background:

  • General movements (GM) are a key indicator of early neurological development.
  • Understanding the typical progression of GM is crucial for identifying developmental deviations.

Purpose of the Study:

  • To characterize the developmental trajectory of general movements (GM) in healthy infants.
  • To investigate the relationship between GM development and other neurological markers.

Main Methods:

  • Longitudinal video recording of spontaneous motility in 22 healthy, full-term infants from 2 to 18 weeks of age.
  • Regular neurological examinations were conducted concurrently with movement assessments.

Main Results:

  • Infant GM transition from a 'writhing' quality (slow, limited amplitude) to a 'fidgety' quality (small, irregular, continuous movements).
  • This transformation is more closely linked to postmenstrual age than postnatal age.
  • Fidgety GM were consistently observed between 8-12 weeks; rapid arm movements ('swipes'/'swats') appeared by 3 months.

Conclusions:

  • General movements undergo a distinct developmental transformation in early infancy.
  • The development of GM and other neurological aspects appear to proceed autonomously within the typical central nervous system.

Anatomical Movements00:51

Anatomical Movements

Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist, metacarpophalangeal,...

Absolute Motion Analysis- General Plane Motion

Visualize a drone, with its propellers spinning rapidly, hovering mid-air. The fascinating movements and operations of this drone can be comprehended by applying the principle of general plane motion.
As the drone's propellers rotate, an upward force is generated that counteracts the force of gravity, enabling the drone to lift off from the ground. This initial movement of the drone is along a straight path, representing a form of translational motion. In this phase, every point on the drone...

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...
Three Developmental Domains01:29

Three Developmental Domains

Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...

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 Infancy01:30

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.
