The assessment of dyspnea in bronchial asthma. 
We report a new quality of life measuring instrument for the self-assessment of dyspnea in bronchial asthma patients while performing a daily activities test.  The instrument was tested for sensitivity to inhaled B-agonist in patients with moderate to severe asthma.  Results indicated that the new scale was a sensitive and simple tool which may be useful in the therapeutic management of bronchial asthma.
