This single-blind, randomized controlled trial aims to investigate the effects of spinal manipulation on neuromuscular control in individuals with anterior cruciate ligament reconstruction during a single-leg vertical drop landing task. The intervention group will receive spinal manipulation, while the control group will not receive any therapeutic intervention. The main question it aims to answer is: • Can spinal manipulation induce changes in muscle activation, co-contraction magnitude, and biomechanical parameters during landing?

The spinal manipulation will target the sacroiliac joint using the global pelvic manipulation technique. Participants will be positioned in lateral decubitus with the ACL-reconstructed limb placed uppermost. The therapist will apply progressive rotation and flexion at the hip and knee joints to increase tissue tension. To establish contact, the therapist's knee will be placed against the participant's flexed knee. A high-velocity, low-amplitude thrust will then be delivered to optimize joint motion, with cavitation being monitored throughout the procedure.
