Overview

Randomized trial investigating postural control dynamics in individuals post-ACLR, showing increased cortical effort but reduced efficiency.

Key Points

  • This research aims to examine the neural and physiological responses related to postural control after ACLR compared to asymptomatic controls.
  • Seventeen ACLR athletes and thirteen controls underwent 100 unpredictable platform translations.
  • Postural responses were analyzed using statistical parametric mapping of hip acceleration.
  • Cortical dynamics were assessed via mobile electroencephalography for perturbation-evoked potentials and effective connectivity.
  • The ACLR group showed significantly higher hip acceleration during both early adjustment and late re-stabilization phases.
  • N1 amplitudes of perturbation-evoked potentials were significantly higher in the ACLR group.
  • Frontocentral information flow was significantly lower shortly after perturbation but increased during re-stabilization.
