Peripheral Arterial disease is a common condition which causes narrowing of the arteries. The most common symptom that patients with PAD experience is Intermittent Claudication (IC), pain in the lower limb(s) on exertion, which is relieved by rest. IC reduces patients' quality of life (QoL) by limiting their ability to walk and engage in daily activities. Regular exercise and physical activity (PA) are central to the management of PAD and help to improve walking distances and reduce the risks associated with PAD such as heart attack and stroke. However, exercise and PA in this population is often limited due to pain. Investigators have shown that Transcutaneous Electrical Nerve Stimulation (TENS) can help to reduce pain and increase walking distance in patients with PAD. Investigators have also shown that educating patients about their condition and helping them to set goals has the potential to increase PA, and quality of life. This study will examine the feasibility of designing a definitive trial that investigates whether TENS can improve the physical activity of patients with PAD when delivered alone and/or alongside a patient education programme.
