Dynamic Plantar Microvascular Skin Response to Compressive Loads in At-risk Diabetic and Healthy Control
The purpose of this pilot study is to compare the dynamic response of microcirculation in
the skin on the bottom of the big toe after applying controlled plantar stress in 25
diabetic subjects with a history of foot ulcer and 25 age-matched healthy controls to better
understand the role of local hypoxia in neuropathic foot ulceration in subjects with
diabetes.
The investigators hypothesize that if they apply a gait simulating load to the plantar foot
and measure microvascular function, diabetic individuals will demonstrate an increased delay
in reestablishing microvascular flow compared to healthy individuals.
