Brief Summary

Overall project design: This PhD project involves a randomized study on diabetic individuals with healing resistant wounds, comparing the effect of passive movement of the lower limb with standard treatment of diabetic wounds. How to effectively improve the condition of peripheral arterial disease is limited. The primary purpose of this study is to uncover whether passive movement of the lower limb will influence muscle oxygen demand and thereby increasing blood flow. An increase in muscle oxygen demand is likely to increase both blood flow rate and the number of capillaries, which would induce the healing of wounds, that were not previously possible. The secondary purpose is to increase understanding of the pathophysiological processes in wound healing through the study of biochemical markers of vascularization, inflammation and stem cell recruitment in blood samples. Further on analyzing the skin and muscle biopsies of the number and quality of endothelial cells and Capillary density and to develop new quantifiable methods to evaluate wound healing in. The project is a randomized trial, consisting of simple passive training to improve blood vessel function, increase the growth of the smallest blood vessels, thereby preventing ulceration and ultimately amputation.
