Baseline Dyspnea Index (BDI)
Please visit this website for more information about the instrument: Baseline Dyspnea Index
Exploratory: Amyotrophic Lateral Sclerosis (ALS)
Short Description of Instrument
The BDI grades the severity of dyspnea at a single point in time and contains three classification axes: functional impairment (activities of daily living), magnitude of task in exertional capacity (intensity of activity), and magnitude of subject effort (effort or difficulty breathing). The BDI is easy to administer and useful for measuring baseline dyspnea levels.
Each axis contains five categories rated 0 to 4. Scores are summed for a baseline score that ranges from 0 to 12.
