The Six-Minute Walk Test is a simple exercise used to assess a person's functional capacity and endurance. During the test, individuals walk as far as possible in six minutes on a flat, straight surface. This test helps healthcare providers evaluate the effectiveness of treatments and monitor changes in a patient's condition over time. The distance covered in the six minutes is measured and recorded. This information can be particularly useful for patients with conditions like chronic obstructive pulmonary disease or heart failure. The test is non-invasive and can be performed in various settings, including hospitals and rehabilitation centers.
