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...

Area of Science:

  • Developmental neuroscience
  • Motor control research
  • Pediatric physical therapy

Background:

  • Variability is recognized as fundamental to typical motor development.
  • Inconsistent definitions and quantification of variability hinder clinical application.
  • Translating developmental research into practical assessment and intervention remains a challenge.

Purpose of the Study:

  • To emphasize the significance of statistical variability and complexity in developing postural control.
  • To outline the implications for assessing and intervening in postural control during infancy and early childhood.

Main Methods:

  • This perspective article reviews existing literature on motor development and postural control.
  • It proposes five tenets to conceptualize the role of variability in supporting movement and development.
  • It introduces evidence related to assessment and intervention strategies focusing on postural control variability.

Main Results:

  • Five tenets are proposed to explain how variability in postural control supports movement experiences, exploration, and overall development.
  • The article highlights the importance of statistical variability and complexity in postural control during development.

Conclusions:

  • Variability in postural control is essential for optimal motor development in infants and young children.
  • A clearer understanding and consistent quantification of variability are needed for effective clinical assessment and intervention.
  • Future research should focus on developing and validating assessment and intervention strategies that incorporate variability principles.
