Brief Summary

Peripheral artery disease (PAD) results in blockages of arteries (blood vessels) and decreased blood flow to the legs. This may cause difficulty or pain with walking or other activities that use leg muscles. Exercise may help improve blood flow in the legs and improve the ability to walk. This research project will be conducted patients with PAD that require revascularization. The goal is to examine the effects of 3 months of exercise rehabilitation or neuromuscular stimulation on leg blood flow, physical function, quality of life and general health.
