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 ACQ is a 7-item self-report questionnaire developed by Juniper and colleagues at McMaster University in 1999 to assess the degree of asthma control in the previous one to two weeks. Unlike generic respiratory tools, the ACQ measures symptom-based control and rescue medication use, providing a simple yet psychometrically sound method for evaluating treatment efficacy. It is widely adopted in clinical trials, guideline-driven care, and routine asthma management to guide therapy titration and assess treatment response.
