Overview

Findings show associations between psychological outcomes and neuromuscular asymmetries in patients post-ACL reconstruction.

Key Points

  • This research compares psychological factors and their association with quadriceps function post-ACL reconstruction.
  • Examined 40 participants (26 ACLR patients, 14 healthy controls)
  • Used psychological assessments and evaluated neuromuscular function
  • Calculated limb symmetry indices for strength and biomechanics using a multimodal dynamometer and motion capture.
  • ACLR patients had poorer psychological outcomes than controls (p < 0.001)
  • Significant asymmetries found in quadriceps strength and jump-landing biomechanics
  • Lower knee self-efficacy linked to greater asymmetries in neuromuscular function.
