Diagnosis
Prompt recognition of Intermittent Claudication is important so that treatment can be given to reduce disability and improve the patient's quality of life.
This early intervention is critical, as a study found that a quarter of patients deteriorate significantly. Up to 2% will eventually require a major amputation.
Intermittent Claudication can usually be easily diagnosed in general practice.
Diagnosis is based on the patient's history and a physical examination, which can be supplemented by measurement of the ankle-brachial pressure index (ABPI), a sensitive marker of blood vessel insufficiency.
Intermittent Claudication usually involves a history of tightness, cramping, or fatigue in the calf, thigh, or buttock muscles in one or both legs. The pain is brought on by exercise and relieved by rest.
