Introduction: Anterior cruciate ligament (ACL) rupture causes instability and impacts gait biomechanics, necessitating neuromuscular adaptations. The initial phase of gait is critical for stability and fall prevention, influenced by postural control and motor coordination.

Objective: To analyze the behavior of the center of pressure (CoP) and neuromuscular adaptations during gait initiation in adults with a complete ACL rupture.

Methodology: Twenty adults with a complete ACL rupture were evaluated. The CoP trajectory was divided into three phases of gait initiation: anticipatory, first step execution, and second step execution. The amplitude and displacement velocity of the CoP in the anteroposterior and mediolateral directions were calculated.

Results: There was a significant decrease in CoP displacements in the anteroposterior and mediolateral directions throughout the gait phases, indicating progressive stabilization of movement.

Conclusion: Individuals with a complete ACL rupture exhibit adaptations in dynamic balance control during gait initiation, aiming for greater stability.
