On the mMRC symptom scale, what score indicates less symptoms in COPD?

A score of 0-1 on the modified Medical Research Council (mMRC) dyspnea scale indicates less severe symptoms in individuals with Chronic Obstructive Pulmonary Disease (COPD). This scale is designed to assess the level of breathlessness experienced by patients and is an important tool in evaluating the impact of COPD on a patient's quality of life.

Scores in the range of 0-1 signify that the individual experiences only mild dyspnea, such as feeling breathless only during strenuous activity or not at all in usual daily activities. This suggests that their COPD has minimal effect on their daily functioning and overall well-being.

In contrast, higher scores (2-3 or 4-5) correspond to more significant levels of breathlessness and indicate a greater degree of symptom burden, suggesting that the patient's COPD is having a more pronounced impact on their daily activities. Thus, the lower the score on the mMRC scale, the less severe the symptoms, making a score of 0-1 indicative of less respiratory distress.
