خلاصه	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 Lower Extremity Functional Scale (LEFS) is a 20-item patient self-report instrument designed to assess functional limitations in individuals with lower extremity musculoskeletal disorders. Developed by Binkley, Stratford, Lott, and Riddle in 1999 and published in Physical Therapy, the LEFS provides a validated, general lower-extremity outcome measure applicable across diverse pathologies (knee, ankle, hip, foot injuries and conditions), making it particularly valuable in physical therapy and rehabilitation settings.
