Cognitive load significantly impacts children's postural control, affecting balance and stability. This developmental neurology study reveals how cognitive tasks alter movement patterns in nine-year-old children.

Area of Science:

  • Developmental neurology
  • Neuroscience
  • Human motor control

Background:

  • Understanding the interplay between cognitive processes and motor skills is crucial in developmental neurology.
  • Postural control, essential for daily activities, may be influenced by cognitive demands.

Purpose of the Study:

  • To investigate the effect of a concurrent cognitive task on postural control in nine-year-old children.
  • To analyze how cognitive load impacts various posturographic parameters and stability factors.

Main Methods:

  • Fifty nine-year-old children completed 60-second balance trials under conditions of cognitive load (mental counting) and no cognitive load.
  • Twelve posturographic parameters (PPs) were extracted from center of pressure (CoP) trajectory data using a force plate.

  • Children were grouped using Teachers Ratings and PANESS assessments to explore individual differences.

    • Main Results:

    • Significant differences were observed in most PPs during cognitive load, with increased CoP velocity and altered frequency spectrum.
    • Nonlinear stability factors indicated increased instability under cognitive load.
    • Grouped analyses revealed specific time and frequency domain differences, confirming cognitive-motor interactions.

    Conclusions:

    • Concurrent cognitive tasks significantly impair postural control in children.
    • Cognitive processes and their development are intrinsically linked to postural control capabilities.
    • Findings highlight the importance of considering cognitive load in assessing and understanding motor development.
