Which shoulder treatment claims are worth believing?

Does a scan show what is causing the soreness?

A scan may show wear or a tendon tear in an arm that works well. Those findings become more common as bodies get older.

Match the picture with strength, motion, and the way your trouble began. If it doesn't change the plan, the finding may not be the main issue.

What does a treatment result really tell you?

Ask whether people slept better, reached farther, or returned to their usual work. A picture that looks different isn't always a result you can feel.

When a claim only mentions a scan, ask about comfort and daily use. That's the part of the result that matters at home.

Why does the length of relief matter?

Early relief can be useful when it helps you sleep or move. It doesn't prove the shoulder will stay better months later.

Ask when the benefit usually starts and when it may fade. You also need a plan for the time after that window closes.

What can you ask before agreeing to care?

Ask what the treatment was compared with, how much better people felt, how long that change lasted, and how often they needed more care when it faded. That long question can save you from a short answer.

Then ask about total cost, time away from normal tasks, and the next choice. If the answer stays vague, you don't have enough to decide.

1. In the MOON Shoulder prospective cohort of 452 patients with symptomatic, ATRAUMATIC full-thickness rotator cuff tears, physical therapy succeeded in more than 70% of patients at 10 years: only 115 (27.0%) had surgery at any point over the decade. Patient-reported outcomes improved with physical therapy and did NOT decline over 10 years in those who never had surgery. The strongest predictor of early surgery was low patient expectation of physical therapy, not tear anatomy.

2. The Cochrane review of manual therapy and exercise for rotator cuff disease included 60 trials and 3,620 participants but could perform no meta-analysis because of clinical heterogeneity and incomplete outcome reporting; risk of bias was high in 43 of the 60 trials. The single high-quality placebo-controlled trial (120 participants) found manual therapy plus exercise no better than inactive ultrasound at 22 weeks on overall pain.

3. The GRASP trial randomized 708 adults with a rotator cuff disorder to progressive exercise (up to 6 sessions), a single best-practice advice session, or either of those preceded by a corticosteroid injection. Over 12 months there was no evidence of a difference in Shoulder Pain and Disability Index between progressive exercise and one advice session (adjusted mean difference -0.66, 99% CI -4.52 to 3.20), and no evidence of a difference between having a corticosteroid injection and not having one.

4. At 10 years, arthroscopic subacromial decompression offered NO benefit over placebo surgery for subacromial pain syndrome: the mean difference in VAS pain was -1.5 points (95% CI -8.6 to 5.6) at rest and -3.2 points (-13.0 to 6.5) on arm activity, against a minimally important difference of 15. It also showed no benefit over exercise therapy.

5. CSAW randomized 313 UK patients with at least 3 months of subacromial pain, intact cuff tendons and a failed non-operative programme to decompression surgery, placebo arthroscopy, or no treatment. Mean Oxford Shoulder Score at 6 months did not differ between the two surgical groups (32.7 versus 34.2; mean difference -1.3, 95% CI -3.9 to 1.3, p=0.31), meaning the bone-and-soft-tissue removal that defines the operation added nothing.

6. The Cochrane review of subacromial decompression for rotator cuff disease pooled 8 trials with 1,062 participants and concluded, on high-certainty evidence from the two low-risk-of-bias placebo-controlled trials, that decompression provides no improvement over placebo surgery.

7. In a nationally representative Finnish population sample of 602 adults aged 41-76 who had bilateral 3-Tesla shoulder MRI regardless of symptoms, rotator cuff abnormalities were found in 98.7% of participants (25% tendinopathy, 62% partial-thickness tear, 11% full-thickness tear). Abnormalities were present in 96% of ASYMPTOMATIC shoulders. Only full-thickness tears were more common in symptomatic shoulders, and that difference all but disappeared after adjustment (absolute difference 0.8%, 95% CI -3.4% to 6.0%).
