tDCS plus exercise to improve motor control after ACL reconstruction

Effects of Transcranial Direct Current Stimulation Over Motor Cortex During Recovery of ACL Patients

Not applicable Interventional Fundación Universidad Católica de Valencia San Vicente Mártir · NCT06818201

This trial will test whether adding non-invasive brain stimulation (tDCS) to exercise-based rehab helps people aged 16–40 recovering from ACL reconstruction regain better muscle control and function.

What this trial studies

Participants who had a complete ACL tear treated with surgery will receive a rehabilitation program that pairs transcranial direct current stimulation (tDCS) targeting the motor cortex with exercise, compared with sham tDCS plus the same exercises. The protocol measures cortical reorganization and corticospinal activation alongside pain, psychosocial measures, and functional outcomes to see if neuromuscular control improves. Key eligibility includes age 16–40 and a Tegner activity level of 4 or higher, while exclusions include other lower-limb pathology, neurological disease, recent concussion, cranial metal, or medications that affect neuronal activity. The study aims to determine whether supraspinal modulation via tDCS can reduce arthrogenic muscle inhibition and enhance recovery after ACL reconstruction.

Who should consider this trial

Good fit: Ideal candidates are people aged 16–40 with a complete ACL tear treated surgically who were moderately to highly active before injury (Tegner ≥4).

Not a fit: Patients with additional knee/leg injuries, neurological disorders, recent concussion, cranial metal implants, or those taking medications that affect brain activity are unlikely to be eligible or to benefit.

Why it matters

Potential benefit: If successful, combining tDCS with exercise rehab could speed recovery of muscle control and reduce the risk of re-injury after ACL reconstruction.

How similar studies have performed: Small trials and pilot studies combining tDCS with physical rehabilitation for motor recovery have shown some promising but inconsistent results, so the approach remains experimental.
