Background Intermittent claudication is usually caused by atherosclerotic stenoses and/or occlusions in the arteries to the legs and affects 7% of the Swedish population aged 60 years or more. Evidence-based treatment is best medical treatment (BMT) and exercise therapy. Best medical treatment includes treatment of risk factors for arteriosclerosis. Regarding exercise therapy, in-hospital supervised exercise therapy (SET) on a graded treadmill is known to improve walking performance as measured on the graded treadmill after three and six months. There is only scarce data on long-term results and very limited data regarding improvement of health related quality of life (HRQoL) by SET. In most countries, walk advice (WA) is routine clinical practice and resources for SET are often lacking. Invasive treatment (surgical or endovascular) is rarely required for patients with intermittent claudication.
