Peripheral arterial disease (PAD) is an obstructive vascular disease of the lower extremities that reduces arterial blood flow during exercise or, in advanced stages, at rest.1 The prevalence of PAD has been estimated to be 10% in the general population, increasing to about 20% in persons older than 70 years of age.2 Individuals with PAD can experience fatigue, cramping, pain with ambulation (intermittent claudication [IC]). Between 3% and 7% of individuals diagnosed with PAD will suffer from IC.2 This symptom can lead to immobility, poor mobility, tissue loss, infection, and possibly loss of limb.
