Duke Activity Status Index (DASI)

The Duke Activity Status Index (DASI) is a simple questionnaire used to assess an individual's level of physical fitness and functional capacity, particularly in relation to cardiovascular health. It asks about a person's ability to perform everyday activities—like walking, climbing stairs, and engaging in household tasks—without discomfort. The responses help healthcare providers understand a patient's functional ability and guide treatment decisions. DASI is particularly useful in evaluating patients with heart conditions or those undergoing rehabilitation, helping to tailor exercise programs and monitor improvements over time.
