Neuromuscular Electrical Stimulation Superimposed or Not on Voluntary Contraction After Reconstruction of the Anterior Cruciate Ligament: a Randomized Controlled Trial
This study aims to evaluate the effectiveness of neuromuscular electrical stimulation with superimposed voluntary contraction (NMES+ group) compared to NMES without voluntary contraction (NMES group) during the initial month of rehabilitation post anterior cruciate ligament reconstruction (ACLR). Forty patients will be randomly assigned to either the NMES group or the NMES+ group. Both groups will follow an identical rehabilitation regimen in the first month after surgery, which includes interventions for symptom management, inflammation control, edema reduction, improved joint motion range, and restoration of muscle function.
All participants will undergo identical assessment protocols at four time points: pre-surgery evaluation, and assessments at 2, 15, and 30 days post-ACLR. The primary outcome of the study is the maximal isometric strength of knee extensors. Secondary outcomes encompass thigh muscle atrophy, self-reported functional impairments, knee pain, knee edema, joint range of motion, and quadriceps activation status.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Joint range of motion
Time Frame: Before surgery, and then at 2, 15, and 30 days post-surgery.
|
Joint range of motion will be assessed using heel-height measurement and goniometry
|
Before surgery, and then at 2, 15, and 30 days post-surgery.
|
Self-reported functional impairments
Time Frame: Before surgery, and then at 2, 15, and 30 days post-surgery.
|
Self-reported functional impairments will be assessed using Lysholm Scale and the Knee Outcome Survey-Activities of Daily Living Scale (KOS-ADLS)
|
Before surgery, and then at 2, 15, and 30 days post-surgery.
|
Quadriceps activation status
Time Frame: Before surgery, and then at 2, 15, and 30 days post-surgery.
|
The quadriceps activation status will be assessed by lag sign.
|
Before surgery, and then at 2, 15, and 30 days post-surgery.
|
Muscle atrophy
Time Frame: Before surgery, and then at 2, 15, and 30 days post-surgery.
|
The evaluation of muscle atrophy will be performed by measuring the circumference of the thigh.
|
Before surgery, and then at 2, 15, and 30 days post-surgery.
|
Knee edema
Time Frame: Before surgery, and then at 2, 15, and 30 days post-surgery.
|
Joint swelling will be assessed using the Stroke Test.

Before surgery, and then at 2, 15, and 30 days post-surgery.
|
Knee pain
Time Frame: Before surgery, and then at 2, 15, and 30 days post-surgery.
|
The severity of knee pain will be assessed through the numerical pain rating scale.
|
Before surgery, and then at 2, 15, and 30 days post-surgery.
