The trunk segmental motion complexity and balance performance in challenging seated perturbation among individuals with spinal cord injury

This study investigates how spinal cord injury (SCI) affects trunk motion complexity during seated balance tasks and how this relates to postural control. The researchers measured trunk motion in individuals with SCI and healthy controls during seated perturbations to understand differences in motion complexity and balance performance. The findings suggest that SCI reduces trunk motion complexity, particularly in the lumbar region, impacting postural stability and accuracy, especially during backward movements.

• 1
  Individuals with SCI showed significantly lower motion complexity in the lumbar and upper thoracic segments compared to healthy controls.
• 2
  Backward perturbations, compared to forward perturbations, resulted in reduced complexity in the lumbar and upper thoracic segments and increased steady-state error.
• 3
  Lower lumbar rotation complexity negatively correlated with MD variability and steady-state error in individuals with SCI, while showing a minor positive correlation with settling time during backward perturbation.
