Overview
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.
Detailed description
The primary objective of this single-center, prospective, open-label, randomized, controlled, two-arm interventional study is to evaluate the effect of local vibration applied during muscle strengthening exercises on quadriceps strength recovery during postoperative rehabilitation following anterior cruciate ligament reconstruction.
The secondary objectives of this study are to evaluate the effect of applying vibration superimposed on muscle contraction on single-leg balance, quadriceps power, perceived exertion and pain, as well as on knee range of motion and muscle symmetry during the 6 weeks of postoperative rehabilitation.
Interventions
- Device Vibramoov, Techno Concept, Mane, France
Local vibration superimposed on muscle contraction (SLV) is delivered using a dedicated device (Vibramoov, Techno Concept, Mane, France), which bears the CE mark (European Medical Devices Directive, Class IIa) and is designed and manufactured in accordance with ISO 13485: 2016. - Other No device
No device applied on quadriceps
Primary outcome measures
- Assessment of Quadriceps Strength Recovery During Postoperative Rehabilitation Following Anterior Cruciate Ligament Reconstruction, With or Without Local Vibration Superimposed on Muscle Strengthening Exercises [Time frame: Before surgery and after 6 weeks of rehabilitation]
