Abstract
Peripheral artery disease (PAD) is characterized by limited blood flow to the limbs due to narrowed peripheral arteries. Blockage of the arteries to the lower limbs causes a common symptom among patients with PAD called claudication. Claudication pain is measured by two parameters: Initial claudication (ICT) is when the patient first notices pain while walking, and absolute claudication (ACT) is when the pain forces the patient to stop walking. Biomechanical analysis has demonstrated that muscle oxygenation in patients with PAD decreases at an increased rate compared to healthy controls. Specific tennis shoes that have additional benefits, spring-loaded and carbon fiber shoes, could also improve muscle oxygenation by absorbing and returning mechanical force, thus decreasing calf muscle demand during walking. Therefore, the objective of this study is to determine how muscle oxygenation changes while patients walk with their normal shoe, a carbon fiber shoe, and a spring-loaded shoe. During testing, patients walked at 1.5 miles per hour at a 0% incline, and the incline was increased by 2% every two minutes. Patients reported ICT and ACT; the treadmill was stopped immediately when ACT was reported. Patients were given their preferred shoes to take home and wear for three months. After three months, the data collection was performed again. From pre- to post-intervention with three months of wear of a carbon fiber or spring-loaded shoe, patients’ ICT, ACT, and muscle oxygenation values all increased from pre- to post-intervention. This knowledge will be useful for clinicians in interpreting whether different types of tennis shoes can improve muscle oxygenation in patients with PAD.
