Individuals with developmental disabilities and tardive dyskinesia show altered postural stability. Force platform analysis reveals significant sway and unique movement patterns, suggesting potential for assessing tardive dyskinesia.

Area of Science:

  • Neurology
  • Biomechanics
  • Developmental Psychology

Background:

  • Postural stability is crucial for daily function.
  • Tardive dyskinesia (TD) is a neurological disorder characterized by involuntary movements.
  • Developmental disabilities can impact motor control and balance.

Purpose of the Study:

  • To investigate postural stability in individuals with developmental disabilities and/or tardive dyskinesia.
  • To compare postural control strategies across different clinical groups.
  • To explore the potential of postural sway measures as an indicator for tardive dyskinesia.

Main Methods:

  • Utilized force platform technology to assess postural sway.
  • Evaluated four groups: developmentally disabled with TD, developmentally disabled without neuroleptic history, TD with normal intelligence, and a healthy control group.

  • Tested postural conditions including static stance with varying arm positions and dynamic arm movements.

    • Main Results:

    • Both tardive dyskinetic and developmentally disabled groups demonstrated increased sway and center of pressure (COP) variability compared to controls.
    • The group with both developmental disability and TD exhibited distinct, task-dependent rhythmic COP motions during stance.
    • Combined effects of developmental disability and TD resulted in unique qualitative and quantitative changes in postural stability.

    Conclusions:

    • Postural stability is significantly impaired in individuals with developmental disabilities and/or tardive dyskinesia.
    • The combination of developmental disability and TD leads to specific alterations in postural control.
    • Postural stability analysis may serve as a valuable tool for assessing the presence and severity of tardive dyskinesia.
