Supervised exercise for intermittent claudication is a first line therapy for peripheral arterial disease, as recommended by the National Institute for Health and Clinical Excellence and the European Society for Vascular Surgery. However 2/3 of British trusts cannot implement this due to gym availability, costs, travel time and the requirement for social distancing. During the COVID-19 lockdown the investigators successfully performed a feasibility study for remotely supervised exercise using an electronic walking log and fortnightly video calls with a physiotherapist. RESET2 aims to compare the benefits of and adherence to remotely supervised exercise with self-directed exercise to absolute walking distance.
