خلاصه	The MRC Dyspnoea Scale is a simple 5-grade ordinal classification of dyspnea severity based on the exertional threshold at which breathlessness limits activity. Developed by the UK Medical Research Council (MRC) in 1959, it remains one of the most widely used dyspnea assessments globally due to its brevity, ease of administration, and strong prognostic correlation in chronic obstructive pulmonary disease and other chronic respiratory diseases. The scale is used in clinical practice, epidemiological surveys, and longitudinal disease monitoring to grade symptom severity and guide treatment intensity.	The SGRQ is a 76-item disease-specific quality-of-life instrument designed to measure health status in patients with chronic respiratory disease, particularly chronic obstructive pulmonary disease (COPD). Developed by Jones and colleagues at King's College London in 1991, it has become the gold standard for assessing functional impact and symptom burden in respiratory populations. The SGRQ is widely used in clinical trials, epidemiological studies, and routine respiratory care to track changes in patient-reported outcomes.
