Exercise With Audible Cues on Motor Unit Behavior in Athletes With Anterior Cruciate Ligament Reconstruction
Thailand40 participantsStarted 2024-10-20
Plain-language summary
The closed kinetic chain (CKC) of terminal knee extension exercise (TKE) is designed to activate VM activity for knee injury training. This CKC exercise is effective for highest recruiting muscle activity, especially safe for post-operative knee surgery. The study of ACL reconstruction rehabilitation guideline suggests that exercises can be applied within the early phase of rehabilitation to prevent knee laxity and less knee pain compared to open chain exercise. Therefore, it is interesting to investigate the effects of TKE exercise synchronized with metronome pace on change of VM motor unit behavior in post operative ACL reconstruction. This study focuses on the immediate effect of 1-seesion TKE and expects that adding metronome during TKE will enhance neuromuscular control of VM and may change motor unit behavior.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
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
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
