The Impact of Superimposed Vibration on the Recovery of Muscle Strength and Function Following Anterior Cruciate Ligament Surgery
62 participantsStarted 2026-04-01
Plain-language summary
Restoring muscle strength following knee ligament reconstruction (of the anterior cruciate ligament, ACL) is a major challenge for the functional success of rehabilitation. Despite advances in rehabilitation protocols, many patients still experience persistent strength deficits several months after surgery. Current rehabilitation strategies rely primarily on neuromuscular training programs aimed at restoring maximum strength and joint range of motion. However, these approaches exhibit significant interindividual variability and do not always fully resolve persistent muscle inhibition. In this context, local vibration appears to be a promising tool. This project aims to evaluate the benefits of repeated application of local vibration superimposed on muscle strengthening exercises (recovery of quadriceps strength, single-leg balance, quadriceps power, perception of effort and pain, knee range of motion) performed during the first six weeks of post-ligamentoplasty rehabilitation. The underlying hypothesis is that the addition of sensory stimulation via vibration, superimposed on rehabilitation exercises, could facilitate muscle activation and, ultimately, accelerate the functional recovery of the quadriceps.The expected results could help validate the use of this approach as a standardized tool within post-ACL rehabilitation protocols, by promoting faster muscle recovery and reducing the duration of functional disability.

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?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
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.
