OBJECTIVE: The aim of the systematically review the short-, intermediate-, and long-term effects of extracorporeal shockwave therapy on pain intensity and shoulder function in individualswith noncalcific rotator cuff tendinopathy. DESIGN: The MEDLINE, CINAHL, SPORTDiscus, and Embase were searched from inception up to June 2023. We included randomized controlled trials that investigated the effects of extracorporeal shockwave therapy on pain intensity and shoulder function. RESULTS: Nine studieswere included with a total sample of 543 individuals. Extracorporeal shockwave therapy was superior to sham extracorporeal shockwave therapy in improving pain intensity at short-term follow-up (standardized mean difference -0.28; 95% confidence interval -0.55 to -0.01). Extracorporeal shockwave therapy was not superior to sham extracorporeal shockwave therapy in improving pain intensity at intermediate- and long-term follow-ups (p > 0.05). Extracorporeal shockwave therapy was not superior to other treatments in improving pain intensity at short- and intermediate-term follow-ups (p > 0.05). Extracorporeal shockwave therapy was not superior to sham extracorporeal shockwave therapy and other treatments in improving shoulder function at short-, intermediate-, and long-term follow-ups (p > 0.05). CONCLUSIONS: Moderate-certainty evidence indicated that extracorporeal shockwave therapy showed small improvement in shoulder pain over sham extracorporeal shockwave therapy at short-term followup. In addition, extracorporeal shockwave therapy was not superior to sham extracorporeal shockwave therapy in improving function, and it was not superior to other treatments in improving shoulder pain and function.
