Traditional ESWT uses a once-weekly treatment schedule over 7 weeks, which takes a long time and leads to low patient compliance. This study aims to test two new high-frequency, short-course ESWT protocols, compare their pain relief, shoulder function improvement, tendon healing effect, safety and treatment adherence with the conventional regimen, and finally establish a more efficient, patient-friendly standardized treatment plan for clinical use. A total of 300 eligible participants will be recruited from 10 top-tier hospitals across China and followed up for 12 months after treatment.",[27],"Partial Rotator Cuff Tears (PRCTs)",[29,30,31,32,33],"Partial rotator cuff tears","Extracorporeal shock wave therapy","High-frequency short-course therapy","Shoulder pain","Treatment adherence","NOT_YET_RECRUITING","2026-06-22",{"date":37,"type":38},"2026-06-29","ACTUAL",{"date":40,"type":21},"2027-01-01",{"date":42,"type":21},"2030-01-01",{"name":44,"class":45},"Peking University Third Hospital","OTHER"]
