Which Patient Group Shows Greater Improvement With Patient Education Alone in Rotator Cuff-Related Shoulder Pain? - A Cohort Study

During the Turkish adaptation of the PKQ-RCRSP questionnaire, written permission was obtained from the original developer. At least two experts independently translated the questionnaire into Turkish, and a single reconciled version was created. This version was back-translated by an independent translator to ensure semantic and conceptual equivalence. Revisions were made following expert panel review and pilot testing. For validation, the PKQ-RCRSP will be administered to participants at baseline (V0). One week later (V1), the questionnaire will be repeated, and participants will be asked if their shoulder problem or knowledge has significantly changed in the past week. Those answering "Yes," who do not return, or who receive any intervention will be excluded from the test-retest analysis. Results from participants answering "No" will complete the test-retest analysis, and all participants' data will be included in other validity analyses. This concludes the validation phase.

Participants in this arm will receive structured patient education sessions for rotator cuff-related shoulder pain. The program consists of two 30-minute face-to-face sessions delivered by a physiotherapist with at least 5 years of experience in orthopedic rehabilitation. Educational topics include disease information, symptom management, treatment options, reducing fear of movement, exercise promotion, pain and stress management, physical activity recommendations, nutrition advice, and lifestyle-specific guidance. Informational brochures will be provided after the first session. The second session, delivered two weeks later, focuses on reviewing progress and enhancing motivation; no new information will be provided.
