The Six-Minute Walk Test (6MWT) is a widely used clinical exercise test that assesses submaximal functional capacity by measuring the distance a patient can walk in six minutes. The test is relatively easy to administer, requires specific safety measures and equipment, and has particular contraindications for patient eligibility. It is especially beneficial for patients with moderate to severe impairments and is commonly utilized in preoperative and postoperative evaluations, as well as for monitoring therapeutic responses in pulmonary and cardiac conditions.
