Effect of extracorporeal shockwave therapy for rotator cuff tendinopathy: a systematic review and meta-analysis.

Shoulder pain from rotator cuff tendinopathy, a condition affecting the tendons that stabilize and move the shoulder, is common and can limit daily function for a long time. This review asked whether extracorporeal shockwave therapy, which delivers pressure waves to the affected tissue, helps compared with sham treatment or other therapies. Pooling 16 randomized trials with just over a thousand patients, the authors found that shockwave therapy was associated with statistically significant improvements in pain scores and in several function and shoulder-outcome scales, along with better external rotation range of motion and a higher overall treatment response rate than controls.

One range-of-motion measure, abduction, did not show a statistically significant difference. What makes this interesting is the consistency of the pain and function results across multiple outcome measures, which strengthens confidence in the direction of effect. Still, the authors describe the evidence as limited, so this should be read as an encouraging but not definitive signal rather than settled proof.

If you've been dealing with shoulder pain from what's called rotator cuff tendinopathy, a problem affecting the tendons that help move and stabilize your shoulder, you may have heard about shockwave therapy as a possible treatment. This treatment uses pressure waves aimed at the sore area.

Researchers combined results from 16 studies involving more than a thousand people to see whether it actually helps compared with sham treatment or other options. They found that people who received shockwave therapy tended to report less pain and better shoulder function and movement than those in comparison groups, and more of them were rated as having a good treatment response. One specific movement measurement, lifting the arm out to the side, didn't show a clear difference between groups. These results are promising, but the researchers themselves describe the evidence as limited, so it's not yet a settled answer.

The studies varied in design and quality, and this summary reflects a body of research still developing rather than a final conclusion about how well shockwave therapy works for everyone with this condition.

This systematic review and meta-analysis addresses a question physiotherapists regularly face when managing rotator cuff tendinopathy, calcific or non-calcific: does extracorporeal shockwave therapy (ESWT) offer measurable benefit over sham or alternative treatments for pain and function. Pooling 16 randomized controlled trials totaling 1093 patients, the analysis found statistically significant improvements favoring ESWT across pain (VAS), multiple function scores (Constant-Murley, UCLA, ASES), external rotation range of motion, and total effective rate, while abduction range of motion did not reach statistical significance. For clinical reasoning, the consistency of significant findings across several independently validated outcome measures adds some weight to ESWT as an option worth understanding within a broader treatment context, though the authors explicitly characterize the overall evidence base as limited.

The abstract does not report heterogeneity statistics, risk-of-bias ratings per domain, or long-term follow-up data, so durability of effect and comparability across calcific versus non-calcific subgroups remain unclear. Importantly, this review does not establish superiority of ESWT over any single specific comparator, since multiple different control conditions (sham, other treatments, placebo) were pooled together, and the abstract does not detail adverse event monitoring, so no safety conclusions can be drawn.
