Exercise with metronome cues for athletes recovering from ACL surgery
Terminal Knee Extension Exercise Synchronize With Audible Cues on Motor Unit Behavior of Vastus Medialis Muscle in Athletes With Anterior Cruciate Ligament Reconstruction
This study tests if using a metronome to guide knee exercises can help athletes recovering from ACL surgery improve their muscle control and function.

What this trial studies
This study investigates the effects of terminal knee extension exercises synchronized with audible metronome cues on neuromuscular control in athletes who have undergone anterior cruciate ligament reconstruction. The focus is on enhancing the activation of the vastus medialis muscle to improve motor unit behavior during rehabilitation. Participants will engage in a single session of this exercise to assess immediate changes in muscle function and control. The study aims to provide insights into how sensory integration techniques can optimize recovery outcomes for athletes post-surgery.
Who should consider this trial
Good fit: Ideal candidates are male or female athletes aged 18-35 who have undergone primary ACL reconstruction within the last two weeks and have mild or no resting pain.
Not a fit: Patients who are non-weight bearing post-surgery or have hearing impairments that prevent them from synchronizing with the metronome will not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could lead to improved rehabilitation outcomes and faster recovery for athletes after ACL reconstruction.
How similar studies have performed: While similar approaches have been explored, this specific integration of audible cues with knee rehabilitation exercises is relatively novel.
Eligibility criteria

Inclusion Criteria: * Male or female participants who receive primary ACL reconstruction within 2 weeks with or without meniscus repair * No or mild resting pain (Numeric rating scale ≤ 3) * Reconstruction procedures using autograft including hamstrings or bone-patella bone grafts * Age range 18-35 years (33). * BMI of 18.5-25 kg/m² (34). * Tegner activity scale ≥ level 4 Exclusion Criteria: * Non-weight bearing within 2 weeks after the operation (prescription from surgeon) * Hearing problem, such as being unable to hear the metronome sound or being unable to synchronize exercises with the metronome correctly * Limitations in knee extension range caused by joint stiffness evaluated by using passive knee range of motion * Unable to perform active and passive ≥ 30º knee flexion on the operative side * History of serious injury or operation of lower back and lower extremities such as fracture * Lower back or lower extremities pain within 6 months before the study * On the pain killer medication
