Study aim: Determining the effect of visual perturbation training on kinematics and kinetics associated with anterior cruciate ligament reinjury during an unanticipated cutting maneuver in athletes Design: A controlled clinical trial with an intervention group, single-blind, randomized by computer random numbers on 24 athletes with a history of anterior cruciate ligament reconstruction. Settings and conduct: Eligible athletes were randomly assigned to control or intervention groups using a random number generator. All participants completed a pre-test at the Sport Sciences Research Institute, with data collectors blinded to group allocation. The control group performed only neuromuscular exercises, while the intervention group did the same training combined with visual disturbance using glasses. After eight weeks of training, participants repeated the post-test, and changes in biomechanical variables were analyzed between groups. Participants/Inclusion and exclusion criteria: Inclusion criteria: Having had a unilateral ACL reconstruction, being within 9-18 months of the reconstruction, having no pain, swelling, and having full and painless range of motion in the knee, ankle, neck, and lumbar joints. Achieving at least 80% of the quadriceps strength of the opposite limb, and performing all hop tests without pain and with an index of at least 80% of the opposite limb. Issuing permission to return to sports by the club's medical team for the athlete. Exclusion criteria: pain during exercise, missing more than 3 training sessions, inability to perform functional tasks (due to visual and/or hearing impairment, vestibular and neurological disorders), re-injury after surgery Intervention groups: Intervention group: Eight weeks of neuromuscular training with visual disturbance Control group: Eight weeks of neuromuscular training Main outcome variables: Knee joint kinematic; Knee joint kinetic; Knee joint performance
