خلاصه	The Nijmegen Questionnaire is a 16-item self-report instrument designed to identify dysfunctional breathing patterns, particularly hyperventilation syndrome, in patients presenting with respiratory or non-respiratory symptoms. Developed by van Beveren and colleagues in the Netherlands in 1994, it provides rapid assessment of symptoms attributable to chronic hyperventilation: dizziness, chest tightness, muscle tension, paresthesias, and anxiety. The Nijmegen Questionnaire is widely used in respiratory physiology clinics, pulmonary rehabilitation programs, and psychosomatic medicine to detect dysfunctional breathing phenotypes that may masquerade as asthma, anxiety disorders, or cardiopulmonary disease.	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.
