概要	The American Shoulder and Elbow Surgeons (ASES) Standardized Assessment Form is a hybrid outcome instrument combining patient self-report and clinician assessment to evaluate shoulder function and pain. Developed by the ASES Committee in 1994 and published in the Journal of Shoulder and Elbow Surgery, the ASES Score has become the standard shoulder outcome measure in orthopedic and sports medicine settings, widely used in clinical trials, surgical registries, and longitudinal outcomes tracking.	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.
