What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Shoulder Pain and Disability Index (SPADI) Total Score from Baseline to Week 8
Shoulder Pain and Disability Index (SPADI) total score (validated Simplified Chinese version; range 0-100, where 0 = no pain/disability and 100 = worst pain/disability; higher scores indicate worse outcome).

Worst shoulder pain in the past 24 hours measured by a Numeric Rating Scale (NRS) item from the Brief Pain Inventory-Chinese version (BPI-C) (range 0-10, where 0 = no pain and 10 = worst imaginable pain; higher scores indicate worse outcome). Assessed at Weeks 0 (baseline), 2, 4, 8, and 12. Endpoint is the change from baseline to Week 8 (Week 8 minus Week 0); negative change indicates improvement.
