- Shock wave therapy at 3 months of follow-up holds few benefits for patients with rotator cuff disease, according to a Cochrane meta-analysis.
Why this matters
- Rotator cuff disease is increasing in prevalence with the aging of the population.
- A meta-analysis of 32 randomized controlled trials and controlled clinical trials (N=2281).
- Funding: No external sources.
- At 3 months of follow-up, achieving pain relief of ≥50% was no better in the shock wave group than the control group (risk ratio, 1.10; 95% CI, 0.62-1.94), with low certainty.
- Pain relief on a visual analogue scale (0-10) was slightly better in the shock wave group (standardized mean difference [SMD], −0.49; 95% CI, −0.88 to −0.11) vs the control group (moderate certainty).
- The absolute effect was 0.78 points better, falling short of being clinically important (cutoff, 1.5 points).
- Function was no better in the shock wave group (SMD, 0.62; 95% CI, 0.13-1.11), with moderate certainty.
- No difference between groups in the number of participant withdrawals for adverse events or treatment intolerance, and no difference in experiencing any adverse events.
- Low to moderate certainty of evidence because of bias.
- Few clinically important benefits.
