The Effects of a Novel, Non-ischemic and Pain-free Exercise Intervention in Peripheral Artery Disease
University of Oklahoma
Summary
This study is a 3-month, prospective, randomized controlled clinical trial designed to address the efficacy of the Non-Ischemic Exercise (NICE) program to improve exercise and vascular outcome measures in patients with peripheral artery disease (PAD).
Description
Specific Aims. The investigator proposes to test our central hypothesis that the NICE intervention performed without inducing leg ischemia and its' damaging sequela will be a superior exercise paradigm to increase peak walking time and HRQoL more than the Standard ischemic and painful exercise paradigm via greater improvement in microvascular mechanisms. This clinically relevant hypothesis will be tested through the following aims: Aim 1 (Exercise Outcomes) To compare the changes in ambulation and HRQoL in PAD patients randomized to either the NICE slow walking program or to the Standard prog…
