What does this research mean for the field?

Individuals with anterior cruciate ligament reconstruction (ACLR) exhibit distinct cognitive and biomechanical profiles that adapt independently, suggesting that rehabilitation should target cognitive function and biomechanical performance separately. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

This study investigates the relationship between visual processing, cognitive interference, and knee angular impulse in individuals after ACL reconstruction.

Implication

Randomized trial examines cognitive differences affecting knee impulse in ACLR individuals, indicating need for tailored rehab strategies.

Key Points

This study investigates the relationship between visual processing, cognitive interference, and knee angular impulse in individuals after ACL reconstruction.
Thirty-two females (16 ACLR, 16 controls) participated in cognitive assessments and drop-jump tasks.
Participants performed jumps under various conditions: standard, choice, visual-cued, and audio-cued.
Cognitive predictors and biomechanics were analyzed using logistic regression and ANOVA.
Three cognitive variables differentiated groups: cognitive interference score, visual simple reaction time, and visual complex reaction time (χ²(3) = 55.090, p < 0.001).
The ACLR group showed faster visual reaction times but poorer interference control compared to controls.
ACLR individuals had lower eccentric knee angular impulse (p = 0.003, d=-0.37), indicating protective strategies.
