Visual-guided balance training to improve knee function after ACL reconstruction

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized controlled trial enrolls adults with primary unilateral ACL reconstruction and begins the intervention at week five after surgery. Participants receive standardized rehabilitation and are randomized to either traditional general balance training or visual-guided balance training, while a healthy control group provides baseline comparison. Outcomes include movement-function tests, gait analysis, and biomechanical measurements to quantify knee joint function and walking performance. The trial compares how effectively visual-guided training narrows the functional gap between post-ACLR patients and healthy individuals.
