ORTHOSTATIC HYPOTENSION

This study tests whether a non-invasive spinal cord stimulation device can help people with chronic spinal cord injury improve autonomic functions like blood pressure, bladder, bowel, and sexual control. About 30 adults with complete paralysis at or above T6 will receive targeted…

This study looks at whether breathing air with a little extra carbon dioxide can raise blood pressure and improve blood flow to the brain in people with neurogenic orthostatic hypotension (NOH). NOH causes a big drop in blood pressure when standing, leading to light-headedness, n…

This study looks at whether carbonated (fizzy) water can help people stay steady on their feet better than plain water. Drinking water is known to raise blood pressure and reduce fainting risk, but it's unclear if the bubbles add extra benefit by stretching the stomach. Researche…

This study tests if special breathing exercises can help pregnant women with POTS, a condition that causes a rapid heart rate and dizziness when standing up. The study will include 44 pregnant women aged 19-35. One group will learn diaphragmatic breathing, while the other gets st…

This study tests a non-invasive spinal stimulation technique to help control blood pressure in people who had a spinal cord injury within the past month. Many of these individuals experience dangerous drops in blood pressure when sitting up, causing dizziness and nausea that can …

This study tests whether gentle electrical stimulation on the back can help people with chronic spinal cord injury maintain healthy blood pressure when they sit up. Participants will lie on a tilt table while their blood pressure is measured with and without stimulation. The goal…

This study aims to understand how the autonomic nervous system—which controls things like blood pressure, skin blood flow, and bladder health—is affected after spinal cord injury. Researchers will perform lab tests and have participants wear a smartwatch to track skin sweat, hear…

This study looks at how the body regulates blood pressure and heart rate in healthy adults and older adults with high blood pressure. Participants will undergo tests like standing up and exercising on a stationary bike while their heart activity and artery stiffness are measured.…

This observational study will follow up to 1,000 adults with conditions like fainting, rapid heartbeat, or low blood pressure who have had or will have a procedure that adjusts nerve signals to the heart. Researchers will track whether symptoms return within a year. The goal is t…

This study looks at how midodrine and droxidopa, two drugs used for low blood pressure upon standing, affect the veins in the abdomen of people with autonomic failure. About 34 adults aged 40-80 with conditions like multiple system atrophy, pure autonomic failure, or Parkinson di…

This study looks at how blood pressure changes when standing up affect thinking and brain blood flow in people with Parkinson's disease. About 60 participants with and without orthostatic hypotension (low blood pressure on standing) will take thinking tests while lying down and s…
