ORTHOSTATIC HYPOTENSION

This study tests whether diaphragmatic breathing exercises can reduce heart rate, blood pressure, and dizziness in pregnant women with Postural Orthostatic Tachycardia Syndrome (POTS). 44 pregnant women will be split into two groups: one doing breathing exercises, the other recei…

This study looks at whether breathing air with a little extra carbon dioxide can help people with neurogenic orthostatic hypotension (NOH) — a condition where blood pressure drops sharply upon standing, causing dizziness and fainting. Researchers will test this in 80 adults (pati…

This study looks at whether carbonated water can help people stay steady on their feet and avoid fainting. Drinking water is known to raise blood pressure, but researchers want to see if the bubbles in carbonated water add an extra benefit by stretching the stomach. 25 healthy ad…

This study tests whether a non-invasive spinal cord stimulation device can improve autonomic functions like blood pressure, bladder, bowel, and sexual control in people with chronic spinal cord injury. Thirty participants will receive targeted stimulation over several weeks. The …

This study tests whether gentle electrical stimulation on the back can help stabilize blood pressure in people who recently had a spinal cord injury. Participants will undergo sit-up tests with and without stimulation to see if it prevents dizziness and keeps blood pressure in a …

This study tests whether mild electrical stimulation on the back can help stabilize blood pressure in people with chronic spinal cord injury who experience dizziness or fainting when sitting up. Five participants will have their blood pressure measured while tilted on a table, wi…

This study tests whether a wearable Holter monitor can detect early signs of fainting in people with orthostatic hypotension or reflex syncope. Forty adults who have already had a tilt-table test will wear the monitor for up to 21 days. The goal is to see if the device can pick u…

This Mayo Clinic study measures how well the autonomic nervous system works after spinal cord injury. Researchers will test blood pressure control and nerve responses in 69 people with and without injury. Participants also wear a smartwatch to track skin signals, heart rate, and …

This study looks at how blood pressure changes when standing 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 st…

This study looks at how the body controls blood pressure and heart rate in healthy young adults and older adults with high blood pressure. Participants will do tests like standing up and cycling while their heart and blood vessels are monitored. The goal is to better understand 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 or Parkinson's disease will participate.…

This study is a registry that collects information from 1,000 adults who have conditions like fainting, rapid heartbeat, or low blood pressure and have received a procedure that adjusts nerve signals to the heart. Researchers will track whether symptoms return within a year. The …
