Title: The Estimation of Ambulation Capacity by History Questionnaire (EACH-Q): An Assessment of Its Validity and Inter-day Reproducibility in Patients With Vascular-type Claudication
Brief Summary: Leg artery disease is a common condition in which fatty deposits develop in the blood vessels that supply the legs. Many patients with leg artery disease experience a cramp-like leg pain during walking that is relieved by rest; this is called intermittent claudication. To help determine the severity of leg artery disease, patients may be questioned about how far they can walk before claudication pain forces them to stop. However, this information is usually of limited use because most patients poorly estimate their walking capacity. The investigators have developed a simple questionnaire to help estimate walking capacity in patients with leg artery disease. The purpose of this study is to test the validity and reliability of this questionnaire. By validity, the investigators mean the extent to which the questionnaire measures what it is supposed to measure (walking capacity). By reliability, the investigators mean the extent to which the questionnaire produces the same results over time when completed on two different days.

The investigators hypothesise that the investigators simple questionnaire will be valid and reliable.
