AUTONOMIC DYSFUNCTION

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 tests a prescription wrist device called NightWare in 125 veterans with PTSD who have frequent nightmares. The device aims to improve sleep quality, which may also reduce the risk of heart disease. Researchers will measure sleep, blood vessel health, and nervous system…

This study tests whether a short-acting beta-blocker called landiolol can keep heart rate below 90 beats per minute during and after major surgery in people with heart risks. About 114 adults aged 45 and older with at least two risk factors (like high blood pressure or heart dise…

This study tests whether a noninvasive spinal cord stimulation device can improve bladder, bowel, and sexual function in people with spinal cord injury. About 60 veterans from Canada and Ukraine will receive either real or sham stimulation alongside standard rehab. The goal is to…

This study tests whether adding a non-invasive brain stimulation technique called repetitive transcranial magnetic stimulation (rTMS) to standard rehab can improve heart rate control, arm strength, and quality of life in stroke survivors. About 44 adults aged 35-80 who had a stro…

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 why some people develop POTS (a condition causing rapid heartbeat and dizziness) after COVID-19. Researchers think a part of the nervous system that normally fights inflammation may not work well in these patients. They will measure immune cells and inflammati…

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 how the autonomic nervous system (which controls heart rate and blood pressure) works in people with Down syndrome. Researchers will measure heart rate, blood pressure, and stress hormones during activities like cold water, fear simulations, exercise, and caff…

This study looks at how certain natural chemicals in the body, like angiotensin-(1-7), affect high blood pressure and damage to the heart and kidneys in children. Researchers will follow 125 children with newly diagnosed high blood pressure and healthy kids for two years, collect…
