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.
