Summary

Children with Developmental Coordination Disorder (DCD) exhibit non-optimal balance control, particularly in challenging situations. Their muscle activity shows weaker coordination with corrective forces, suggesting underlying neurological differences.

Area of Science:

  • Motor Development
  • Neuroscience
  • Pediatrics

Background:

  • Static balance is crucial for normal motor development and assessed in developmental tests.
  • Children with Developmental Coordination Disorder (DCD) often struggle with static balance tasks.
  • Previous research suggests DCD balance issues emerge in difficult or novel situations.

Purpose of the Study:

  • To investigate the correlation between electromyography (EMG) and force plate signals during one-leg stance in children.
  • To compare balance control mechanisms in children with DCD and balance problems versus typically developing controls.
  • To explore potential structural deficits, specifically cerebellar involvement, related to DCD balance impairments.

Main Methods:

  • Examined EMG signals from leg muscles (tibialis anterior, peroneus) and force plate data during one-leg stance.

  • Included four groups: two age-matched groups, a group of children with DCD and balance problems, and their controls.
  • Analyzed stable and unstable balance epochs to assess corrective responses.

    • Main Results:

    • Tibialis anterior and peroneus muscles are vital for lateral balance control across all participants and conditions.
    • Children with DCD and balance problems demonstrated a weaker coupling between EMG and corrective forces compared to controls.
    • This weaker coupling indicates less optimal postural control in the DCD group.

    Conclusions:

    • Static balance control is generally adequate for children with DCD under normal conditions.
    • Balance deficits in DCD manifest primarily in challenging, unattended, or novel situations, characterized by increased postural sway.
    • Findings suggest cerebellar involvement as a potential structural deficit underlying DCD-related balance problems.
