Peripheral arterial disease (PAD) is an atherosclerotic disease that significantly affects both the functional level and the quality of life of the patient, resulting in a reduction in walking distance or, in more severe stages, rest pain, ischaemic ulcers and limb loss; furthermore, PAD patients have increased morbidity and mortality from cardiovascular and cerebrovascular ischaemic events. Exercise has been recognised having a pivotal role in the treatment of PAD patients in all specific guidelines since a large amount of studies have demonstrated that it can improve walking distance and quality of life, cardiovascular risk profile, vascular perfusion and tone of mood. Through specific protocols, it can be applied to claudication and critical limb ischaemia. In claudicant patients, supervised exercise protocols demonstrated a great efficacy, as an alternative option home based exercise protocols with periodical revision may be a good choice; wearables tools for monitoring may be of help in improving adherence to exercise prescription.
