ORTHOSTATIC HYPOTENSION

This study tests a non-invasive spinal cord stimulation device in 30 people with chronic spinal cord injury. The goal is to see if it can help control blood pressure, bladder, bowel, and sexual function. Participants will receive stimulation over several weeks and be monitored fo…

This study looks at whether breathing a little extra carbon dioxide can raise blood pressure and improve blood flow to the brain in people with neurogenic orthostatic hypotension (NOH), a condition where blood pressure drops sharply upon standing, causing dizziness or fainting. R…

This study tests a non-invasive spinal stimulation technique to help people with a recent spinal cord injury (within 30 days) manage blood pressure drops when sitting up. Participants will receive both real and sham stimulation during a sit-up test to see if it can prevent dizzin…

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 looks at how the body controls blood pressure and heart rate in healthy adults and older adults with high blood pressure. Researchers will measure heart activity and artery stiffness during standing and exercise. The goal is to better understand these processes and hel…

This study looks at how two medications, midodrine and droxidopa, affect the veins in the abdomen of people with autonomic failure—a condition where the body can't control blood pressure properly. Researchers will measure changes in heart function when participants are tilted upr…

This study is creating a large database of 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 over 12 months. The goal is …

This study looks at whether carbonated water can help people maintain blood pressure when standing, reducing the risk of fainting. Researchers will compare the effects of carbonated and still water in 25 healthy adults. The goal is to see if the bubbles make a difference in preve…

This study aims to understand how the autonomic nervous system (which controls things like blood pressure and sweating) works after a spinal cord injury. Researchers will test about 69 people with and without spinal cord injury using simple lab exercises and smartwatches that tra…

This study looks at how blood pressure changes when standing up affect thinking and blood flow in the brain for people with Parkinson's disease. About 60 participants, some with and some without low blood pressure upon standing, will take thinking tests while lying down and stand…
