Compensatory muscle activity for sitting posture during upper extremity task performance in paraplegic persons.

Summary

Spinal cord injury (SCI) patients use back muscles differently to maintain balance during reaching tasks. SCI individuals also show slower movement anticipation and impaired information processing compared to controls.

Area of Science:

  • Neuroscience
  • Biomechanics
  • Rehabilitation Medicine

Background:

  • The erector spinae (ES) muscle is crucial for postural stability.
  • Spinal cord injury (SCI) can lead to loss of postural control.
  • Understanding compensatory mechanisms in SCI is vital for rehabilitation.

Purpose of the Study:

  • To investigate compensatory postural activity in spinal cord injured (SCI) subjects.
  • To compare muscle activation patterns during reaching tasks between SCI and control groups.
  • To assess the impact of SCI on movement anticipation and information processing.

Main Methods:

  • Electromyography (EMG) recorded activity of latissimus dorsi (LD) and trapezius pars ascendens (TPA) muscles.
  • Subjects performed horizontal reaching movements in a sitting position to induce body disbalance.

  • Body center of gravity (CoG) displacement measured postural instability.
  • Directional cues were used to examine anticipatory effects.

    • Main Results:

    • SCI subjects utilized both LD and TPA muscles for postural stabilization, unlike controls.
    • Paraplegic individuals demonstrated slower anticipatory responses to reaching movements.
    • Impaired processing of precued information was observed in SCI subjects before upper extremity movements.

    Conclusions:

    • Paraplegic individuals exhibit altered muscle recruitment strategies for postural control post-SCI.
    • Movement anticipation and information processing are significantly affected by spinal cord injury.
    • Findings highlight potential targets for therapeutic interventions in SCI rehabilitation.
