- Brief Summary
Injury to the anterior cruciate ligament (ACL) is very common among sports professionals and the general population \[. Unlike other joint injuries, it is reversible, but it can damage adjacent tissues, particularly the meniscus, and catalyze knee osteoarthritis.
ACL injury produces instability, joint mechanical alteration, which can lead to degenerative joint diseases. The goal of treating the injury will be to prevent symptomatic instability, restore normal knee kinematics, and prevent degenerative joint disease .
Its usual treatment is surgical and therefore contributes to a significant cost for the health system, both for the surgeries themselves, and for the rehabilitation and subsequent recovery processes.
Within recovery therapies, in some cases, and given their popularity within the world of physiotherapy, electrotherapy techniques are proposed, primarily transcutaneous electrical nerve stimulation-type techniques with action on the muscular system and analgesia.
An early intervention with neuromuscular electrostimulation electrotherapy (NMES) combined with repeated exercises is effective for the recovery of strength and restoration of the biomechanical symmetry of the limb.
There is a diversity of opinions and disparate results regarding the use of this type of technique , in any case, it has been shown that electrical stimulation favors cell migration and joint tissue regeneration.
- Detailed Description
The design of this study is a randomised, triple blind clinical trial with placebo control.
The general configuration of the study consists of capturing a group of patients treated with the same ACL surgical technique, operated on by the same surgeon, and including an additional treatment with the NESA XSIGNAL® device in a group of them.
For this, a double-blind capture system will be available (neither users nor specialists responsible for recovery will know which patients enter the complementary treatment) and two NESA XSIGNAL® devices operating double-blind (due to the imperceptivity of the stimulation performed, there will be a placebo machine and another that applies the treatment).
At the end of the study, the results obtained between the different groups of patients will be able to be compared; those additionally treated with a device, those treated with a placebo device and those in the standard rehabilitation procedure without a device.

- Primary Outcome Measures
Name Time Method Knee circumference Up to 4 month Centimeter measurement supra and infrapatellar with a tape measure with the leg in extension and without muscle contraction.
Functional ability Up to 4 month We will use the International Knee Documentation Committee (IKDC) questionnaire.
Level of Pain Up to 4 month The Visual Analogue Scale (VAS) will be used to measure the perception of pain, which consists of a longitudinal line with 11 values ranging from 0 (none The Visual Analogue Scale (VAS) will be used to measure the perception of pain, which consists of a longitudinal line with 11 values ranging from 0 (no pain sensation) to 10 (maximum pain imaginable)
Motor Control Up to 4 month It will be assessed through a dop jump, vertical jump test and Single leg squat.
- Secondary Outcome Measures
Name Time Method Brain activity Up to 4 month Brain activity will be measured through an Electroencephalogram (EEG). Corresponds to a technique for studying the electrical activity of the brain through electrodes located on the scalp The parameters to be measured are the waves beta (13-30 Hz), which are produced when a subject is awake doing cognitive work and perceiving environmental stimulus
Range of motion Up to 4 month To measure this variable, we will use a goniometer, which will align its fixed arm with the proximal segment of the limb, and the mobile arm with the distal segment, making its axis coincide with the axis of knee movement . 3 measurements will be carried out actively and another 3 passively, choosing the highest value obtained for each one. Flexion and extension movements will be analyzed.
Quality of life related to health Up to 4 month The SF-12 scale will be applied
Psychological perception test: Up to 4 month TSK-11SV questionnaire (version adapted to Spanish). It is an 11-item questionnaire about fear of movement or injury. Patients have to indicate their degree of agreement with each of the statements presented, using a Likert-type scale from 1 (totally disagree) to 4 (totally agree). This questionnaire is designed to also assess the avoidance dimensions of activity and harm, but in this work we will only use the total score. High scores indicate greater fear of movement
