Paper Abstract

Autonomic Dysreflexia (AD) is an uncontrolled response of sympathetic output occurring in individuals with an injury at the sixth thoracic (T6) neurologic level. Any noxious stimulus below the injury level can trigger an AD episode. Progression of an AD attack can result in severe vasoconstriction below the injury level. Skin oxygenation can decrease up to 40% during an AD event. We present a quantitative and non-invasive method of assessing the progression of an AD event by measuring patient's skin oxygen levels and blood flow using a fiber optic based system.
