Retraining the brain to ease carpal tunnel pain: a new approach put to the test
NCT ID NCT07800260
First seen Sep 02, 2026 · Last updated Sep 03, 2026 · Updated 1 time
Summary
This trial tests whether adding a brain-training method called Graded Motor Imagery (GMI) to standard nerve exercises helps people with carpal tunnel syndrome more than the exercises alone. GMI involves three stages over six weeks: recognizing left versus right hands in pictures, imagining moving the affected hand, and using mirror therapy. The study includes 46 adults aged 30 to 60 with mild to moderate carpal tunnel syndrome, and it measures changes in pain, hand function, and grip strength.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Graded Motor Imagery (GMI), a three-stage brain-training program (hand recognition, imagined movement, mirror therapy) added to progressive neurodynamic exercises
- What this could lead to
- If it works, adding brain-focused training to standard exercises could offer a more effective, drug-free way to reduce pain and improve hand function in carpal tunnel syndrome.
- What could go wrong
- This is a small early-stage trial with 46 participants, so results may not apply to everyone. The added training may not provide extra benefit over exercise alone, and some people may find the mental tasks challenging.

Inclusion Criteria: * mild to moderate unilateral CTS based on the Bland classification of electrodiagnostic testing ; * positive Phalen or Tinel tests; * symptoms such as paresthesia and pain associated with CTS that last longer than 3 months; * patients aged 30-60 years (when CTS becomes more prevalent); * patients who achieved a minimum score of 24 on the Mini-Mental State Examination (MMSE). Exclusion Criteria: * bilateral CTS; * history of prior CTS surgery; * clinical indicators of cervical radiculopathy or polyneuropathy; * pregnancy or cognitive impairment; * the presence of orthopedic, neurological, or functional problems on the unaffected side that could affect hand function (e.g., history of trauma or surgery, peripheral nerve injury, tendinopathy, tenosynovitis, trigger finger, arthritis, sequelae of a fracture, etc.); * receipt of any conservative treatment for CTS within the last month.
