Overview

Randomized trial shows neural adaptations in postural control following ACL reconstruction, indicating the role of visual information.

Key Points

  • This study aims to explore functional brain network characteristics related to balance control in individuals after ACL reconstruction while considering visual information.
  • Compared 27 individuals after ACL reconstruction with 24 non-injured controls during single-leg balance tasks under eyes-open and eyes-closed conditions.
  • Derived graph-theoretical measures from mobile electroencephalography, including clustering coefficient and path length.
  • Analyzed group effects using permutation-based ANCOVA.
  • The ACLR group showed greater cortical network segregation (higher CC; p = 0.025) during eyes-open conditions.
  • Sway characteristics were similar between groups, but the ACLR leg displayed greater knee flexion compared to the contralateral leg (p = 0.036).
  • Post-ACLR individuals exhibited more efficient functional brain connectivity when vision was available.
