Not applicable Interventional University of Valencia · NCT05478902

This study is testing which non-surgical treatment—exercise therapy, shockwave therapy, ultrasound-guided irrigation, or doing nothing—works best to relieve pain and improve function for people with rotator cuff calcific tendinopathy.

What this trial studies

This study aims to evaluate the effectiveness of an exercise therapy program against extracorporeal shockwave therapy, ultrasound-guided percutaneous irrigation, and a wait-and-see approach for patients with rotator cuff calcific tendinopathy. It will involve a randomized, single-blinded design with 116 participants divided into four groups. The study seeks to determine which non-surgical intervention provides the best outcomes in terms of pain relief and functional improvement. The interventions will be compared to assess their impact on the quality of life of individuals suffering from this condition.

Who should consider this trial

Good fit: Ideal candidates are individuals with confirmed calcification deposits in the rotator cuff who experience pain and loss of shoulder function.

Not a fit: Patients with other shoulder disorders, recent treatments, or systemic diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide patients with effective non-surgical treatment options for rotator cuff calcific tendinopathy.

How similar studies have performed: Previous studies have shown promise for non-surgical interventions in similar conditions, but the specific combination of treatments in this study is novel.
