Резюме	The Rotator Cuff Quality of Life Index (RC-QoL) is a rotator cuff-specific outcome instrument that measures symptom impact and functional limitations in patients with rotator cuff disease. Developed within rotator cuff treatment literature, the RC-QoL captures the physical, emotional, and social burden of rotator cuff pathology—pain, functional limitations, sleep disturbance, psychological distress—providing a patient-centered perspective on disease impact beyond mechanical function alone. The RC-QoL is widely used in rotator cuff repair and conservative management outcome studies.	The Global Rating of Change (GRC) Scale is a single-item, self-report outcome measure that asks patients to rate the overall change in their condition since baseline assessment. Developed by Jaeschke, Singer, and Guyatt in 1989 and published in Controlled Clinical Trials, the GRC Scale has become a fundamental method for anchor-based interpretation of change scores on clinical outcome measures, enabling clinicians and researchers to determine the minimal clinically important difference (MCID) in standardized scales.
