Assessment of Quadriceps Strength Recovery During Postoperative Rehabilitation Following Anterior Cruciate Ligament Reconstruction, With or Without Local Vibration Superimposed on Muscle Strengthening Exercises

Overview

Brief 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.

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.

Arms & Interventions

Traditional rehabilitation without vibration

Sham Comparator

Intervention: No device (Other)

Application of localized vibration during certain muscle-strengthening exercises

Experimental

The stimulation is delivered at 100 Hz with an amplitude of 2-3 mm, parameters that allow for optimal activation of Ia afferents (Eklund et al., 1966). Contact is provided by a 5 cm × 1 cm skin interface positioned on the muscular body of the quadriceps of each thigh.

Intervention: Vibramoov, Techno Concept, Mane, France (Device)

Outcomes

Primary Outcomes

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

Measurement of changes in strength, with or without vibrations applied to the quadriceps during rehabilitation sessions. Quadriceps strenght will be measured by the maximum voluntary isometric contraction (MVIC): maximum force (kg) while seated. A quadriceps warm-up will begin with progressive isometric contractions, consisting of ten knee-extension contractions of the injured leg, ranging from light to strong intensity depending on the patient's perception. Following this, the patient will perform two 5-second maximal voluntary isometric contractions (MVICs) in extension, separated by 1-minute recovery periods, to measure quadriceps strength.
