Tóm tắt	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.	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.
