Сводка	The Patient-Specific Functional Scale (PSFS) is a unique, individualized outcome instrument that captures patient-identified functional limitations and tracks change in those specific activities. Developed by Stratford and colleagues in 1995 and published in Physiotherapy Canada, the PSFS revolutionized patient-centered assessment by allowing each patient to identify and rate the three to five activities most important to them, rather than answering predetermined questions. This approach ensures relevance and maximizes the instrument's sensitivity to clinically meaningful change in patient-valued outcomes.	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.
