Exercise rehabilitation for patients with peripheral arterial disease.
Intermittent claudication, resulting from PAD, impairs functional status. Reducing the disability result from the disease is therefore an important goal of treatment. To evaluate the efficacy of an intervention designed to improve functional status requires that appropriate outcome measures be developed to assess all treatments. Such outcome measures include graded treadmill testing and questionnaire assessment. These methodologies are important because they have a high degree of precision and accuracy and are practical and reproducible. Thus, functional status changes resulting from any intervention can be evaluated, and interventions can be compared with one another using the same methodologies. Currently, interventional therapies are often used to treat a portion of patients with claudication [49]. Such therapies restore blood flow and improve functional status, but with a high associated cost: morbidity and mortality. Pharmacological therapies currently are being developed, but the role of drugs in the overall management of claudication needs further study. Importantly, exercise therapy has been shown in numerous studies to be efficacious and very well tolerated by patients. Patients improve both their walking ability in the laboratory and their community-based functional status. Because of the efficacy of this treatment, in addition to the low associated morbidity, exercise therapy is recommended as a major treatment option for persons with intermittent claudication due to PAD.
