Peripheral arterial disease (PAD) is a category of cardiovascular disease, characterised by intermittent claudication. This is defined as walking induced pain, cramping, aching, tiredness or heaviness in one or both legs that does not go away with continued walking and is relieved with rest. It is estimated that between 5-10% of individuals aged over 50 years suffer from claudication. The primary and most effective treatment for these patients is focused on improving walking ability and functional status.
