Overview

This study will incorporate critical cross viscero-visceral intersystem interactions to 1) investigate in a controlled laboratory setting and then with mobile at-home monitoring the extent, severity, and frequency of occurrence of autonomic dysreflexia with respect to daily bladder and bowel function, in conjunction with identifying potential underlying mechanisms by examining urinary biomarkers for several specific vasoactive hormones, and 2) to regulate cardiovascular function therapeutically as part of bladder and bowel management using spinal cord epidural stimulation.
