Frozen shoulder patients may get relief by working out the other arm
NCT ID NCT07510737
First seen Jun 25, 2026 · Last updated Sep 11, 2026 · Updated 4 times
Summary
This study tests whether cross training—exercising the healthy arm—can improve pain, function, and mobility in people with frozen shoulder, without directly working the painful shoulder. About 38 adults aged 18-65 with unilateral frozen shoulder will be randomly assigned to standard physical therapy or standard therapy plus cross training for eight weeks. The goal is to see if this indirect approach reduces disability and speeds recovery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- cross training (unilateral resistance exercise on the unaffected side)
- What this could lead to
- If it works, this could offer a gentler rehab option for frozen shoulder that avoids stressing the painful shoulder.
- What could go wrong
- This is a small, early-stage trial with only 38 participants, so results may not apply to everyone. The benefit of cross training for frozen shoulder is still unproven.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Having a diagnosis of unilateral primary or secondary frozen shoulder. * Range of motion in external rotation, abduction, or flexion reduced by less than 50% in at least one of these directions compared to the unaffected shoulder. * Loss of joint range of motion exceeding 30% in at least two movement planes compared to the unaffected shoulder. * Aged between 18 and 65 years. Exclusion Criteria: * Presence of a concomitant shoulder injury (e.g., rotator cuff tear). * Osteoarthritis in both shoulders or in the acromioclavicular joint. * Previous treatment for frozen shoulder. * Psychiatric disorders that may interfere with adherence to medical or physical therapy. * Presence of other neurological disorders. * A score below 24 on the Mini-Mental State Examination (MMSE).
