Summary
Dr. Jeremy Schroeder and Dr. Peter Rippey review a 2024 systematic review and meta-analysis on extracorporeal shockwave therapy for rotator cuff tendinopathy, published in BMC Musculoskeletal Disorders. The analysis included 17 randomized controlled trials with 1,131 patients aged 50-60, comparing ESWT plus rehabilitation to rehabilitation alone. The meta-analysis found statistically significant improvements in pain (VAS scores) and function across multiple outcome measures (UCLA, ASES, Constant-Murley scores) for the shockwave group. No significant improvement was found for abduction range of motion. The majority of studies used radial shockwave (11 of 17), with subgroup analysis showing trends toward improvement regardless of intensity or shockwave type. Despite high heterogeneity among studies, ESWT was deemed a safe adjunct with a good safety profile, though more standardized studies are needed before widespread insurance coverage.
Key Points
- Meta-analysis of 17 RCTs with 1,131 patients found statistically significant pain and function improvements with ESWT
- Shockwave plus rehabilitation outperformed rehabilitation alone across most outcome measures
- No significant improvement was found for abduction range of motion specifically
- Most studies used radial shockwave (11 of 17) with 4-10 weekly sessions
- Subgroup analysis showed improvement trends regardless of shockwave intensity or type (radial vs focused)
- Safety profile was good with no significant adverse events beyond transient procedural pain
- More standardized studies with consistent protocols are needed for insurance reimbursement
Key Moments
Meta-analysis of 17 RCTs shows shockwave improves rotator cuff pain and function
A 2024 systematic review of 17 randomized controlled trials with 1,131 patients found that extracorporeal shockwave therapy produced statistically significant improvements in pain and function for rotator cuff tendinopathy compared to rehabilitation alone.
"This is a systematic review and meta-analysis published in the May 2024 issue of BMC Musculoskeletal Disorders by Zhu et al."
Both radial and focused shockwave show improvement trends
Subgroup analysis dividing studies by intensity and type (radial vs focused) found trends toward improvement regardless of which modality was used, though more standardized research is needed.
"the subgroup analysis that they did in this article dividing the intensities and whether it was radial or focused found a trend towards improvement regardless of which intensity was used or whether it was radial or focused."
ESWT as a safe adjunct to rehabilitation for shoulder tendinopathy
Despite methodologic limitations, the meta-analysis concludes that shockwave is a safe treatment with a good safety profile that can serve as a useful adjunct to rehabilitation for rotator cuff tendinopathy.
"I would say that it might be a good adjunct to add to someone who's getting rehab for a rotator cuff tendinopathy."
