สรุป	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.	The Foot and Ankle Outcome Score (FAOS) is a 42-item patient self-report instrument designed to assess symptoms, function, and activity limitations in individuals with foot and ankle pathology. Developed by Roos and colleagues in 2001 and published in the Journal of Orthopedic & Sports Physical Therapy, the FAOS has become the standard outcome measure in foot and ankle surgery and rehabilitation research, providing comprehensive evaluation across pain, stiffness, physical function, sport/recreation, and foot-ankle-related quality of life.
