This study tests whether the drug landiolol can safely keep heart rate below 90 beats per minute during major surgery in 114 patients with heart risks. The goal is to see if this approach is feasible and might reduce heart injury after surgery. Participants receive the drug throu…

This study tests an experimental drug called ALN-SNCA in 46 people with early Parkinson's disease. The drug is designed to lower levels of a harmful protein, alpha-synuclein, in the brain. The main goal is to check if the drug is safe and tolerable, and to see how it moves throug…

This study tests a method to fine-tune epidural spinal cord stimulation in 100 adults with complete spinal cord injuries between C6 and T10. The goal is to help them regain voluntary leg movement and improve functions like blood pressure control. Participants must be at least 22,…

This study tests whether an implanted spinal cord stimulator can improve autonomic functions like blood pressure and heart rate in people with chronic cervical spinal cord injury. The device delivers electrical pulses to the spinal cord to help regulate involuntary body processes…

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

This study tests a new way to treat children with gut-brain disorders like cyclic vomiting and functional dyspepsia. The therapy uses a mild electrical nerve stimulation to the ear, personalized based on each child's nerve activity. The goal is to improve quality of life and redu…

This study tests whether repetitive transcranial magnetic stimulation (rTMS) can improve heart rate variability and quality of life in people who have had a stroke. 44 participants will receive either real or sham rTMS for 4 weeks. The goal is to see if this brain stimulation can…

This study tests if a nerve block injection in the neck can reduce long-COVID symptoms like fatigue, brain fog, and heart palpitations. About 78 adults with post-COVID condition will get either the real block or a fake injection to see if it helps. The goal is to find a safe, eff…

This pilot study tests whether a device called Cereset Research can help caregivers of people with dementia who feel stressed, anxious, or have trouble sleeping. The device plays tones that echo the brain's own rhythms, aiming to improve heart rate variability and reduce stress. …

This study tests a device called Cereset Research to see if it can improve how the body handles stress, anxiety, and insomnia. About 200 adults with these symptoms will use the device while researchers measure heart rate and blood pressure changes. The goal is to find a non-drug …

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 a prescription wrist device called NightWare that detects when a veteran with PTSD is having a nightmare and gently disrupts it without waking them. Researchers want to see if better sleep from fewer nightmares can also improve blood vessel and heart health. 125 …

This study looks at how a stroke can disrupt the body's automatic functions, like heart rate and blood pressure control. Researchers will compare 100 people who had a stroke or a mini-stroke using brain scans, blood tests, and heart function tests. The goal is to understand why t…

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 stress responses using virtual reality, cold water, pain patches, caffeine, and exercise in 200 participants. The goal is…

This study looks at how common mild depression is in people who have had their first heart attack. Researchers will follow 100 patients for 12 months to see if these mild symptoms affect recovery, heart health, and quality of life. The goal is to better understand the link betwee…

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 is observing 120 people with chronic pain to learn how to design a more effective pain clinic. Researchers will track pain levels, medication use, and overall well-being. The goal is to understand what patients need, not to test a new treatment.

This study explores whether high-intensity interval training (HIIT) is a feasible and acceptable option for people with long-term shoulder pain, such as rotator cuff issues or frozen shoulder. Researchers will enroll 15 people with shoulder pain and 15 without, measuring inflamma…

This study looks at whether Parent-Child Interaction Therapy (PCIT) can help parents and children dealing with anxiety, depression, and stress. About 80 parents of children aged 2-7 will complete surveys and provide saliva samples to measure oxytocin levels. The goal is to unders…

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 compare 150 adults with and without…

This study is looking at children ages 7 to 18 who have been newly diagnosed with high blood pressure. Researchers want to understand how certain hormones in the body, like angiotensin-(1-7), may contribute to damage in the heart, kidneys, and blood vessels. Over two years, they …

This small pilot study aims to see if a new in-ear wearable device can comfortably and reliably measure blood flow changes in the head. Researchers will compare people who have low blood sugar after bariatric surgery to those who don't. The goal is to learn if this device can hel…

This study looks at children with ROHHAD syndrome, a rare condition that causes rapid weight gain and breathing problems. Researchers will take blood samples to create special cells in the lab and study their genetic activity. The goal is to understand what goes wrong in the body…

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 …
