Can mirror therapy and action observation rewire the brain to ease shoulder pain?
NCT ID NCT06823206
First seen Sep 17, 2026 · Last updated Sep 18, 2026 · Updated 1 time
Summary
Researchers are testing whether a 12-week program that combines movement representation techniques with sensorimotor training can reduce shoulder pain in adults aged 50 and older who have had rotator cuff related shoulder pain for more than three months. The program uses action observation, mirror therapy, and shoulder control exercises. Participants are randomly assigned to the training or to standard care. The study measures pain, disability, brain structure, shoulder joint space, and pain-related beliefs to understand how the treatment might work.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- sensorimotor training combined with movement representation techniques, including action observation and mirror therapy
- What this could lead to
- If it works, this approach could offer a non-drug way to ease long-lasting shoulder pain and change how the brain controls the shoulder.
- What could go wrong
- This is a single-center trial of 122 people, so results may not apply to everyone with shoulder pain. The training may not outperform standard care, and brain imaging changes may not translate into less pain.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Aged 50 or above * Presence of shoulder pain for more than three months * Clinical test showed 3/5 positive tests (painful arc, resisted external rotation, Neer test, Kennedy-Hawkins test, and Jobe test), and the intensity of pain being provoked should be ≥ 3/10 on an 11-point numeric pain rating scale (NPRS) * Structural changes of rotator cuff tendons using MRI or ultrasound imaging Exclusion Criteria: * History of trauma * Shoulder fracture, glenohumeral osteoarthritis, or arthritis in the acromioclavicular joint * Clinically suspected labrum lesion * Previous shoulder surgery or dislocation * Clinical signs of anterior shoulder instability * Clinical signs of frozen shoulders * Previous clinical treatment or corticosteroid injection for a shoulder injury within the last 12 months * Symptoms referred from or related to the spine; and (9) other competing diagnoses (i.e., rheumatoid arthritis, cancer, neurological disorders, fibromyalgia, or psychiatric illness).
