Recruiting studies
- NCT05555771Recruiting
Kids with fainting episodes after arriving at the emergency room
This study looks at children and teens (ages 6–18) who recently fainted but are now back to normal, using a survey. It aims to better understand fainting episodes that happen before the emergency visit and how to evaluate them safely.
Vancouver, British ColumbiaAges 6–18 - NCT05633693Recruiting
Exercises to help children with fainting and blood-pressure drops
This study tests whether teaching special standing/balance movements can reduce fainting episodes in children who have recurring vasovagal fainting or certain forms of POTS. It may help your child feel more stable when standing and improve symptoms, while researchers measure balance and “counterpressure” responses during the tests.
Burnaby, British ColumbiaAges 6–18 - NCT07195903Recruiting
Stand-up study for dizziness when standing
This study tests a new approach to help people who feel dizzy or faint when standing up, especially if standard treatments haven't worked. It aims to improve daily life and reduce risks from low blood pressure.
Roslyn, New YorkAges 18 years+ - NCT04271878Recruiting
Test breathing and blood-pressure response in POTS patients
This study measures how breathing patterns and heart rate/blood pressure change when you move from lying to standing in people with POTS. It may help researchers understand symptoms better and improve ways to manage them.
Calgary, AlbertaAges 18–60 - NCT02725060Enrolling by invitation
Study of autoimmune changes in postural tachycardia syndrome
This trial studies whether an autoimmune (immune system–related) process is involved in postural tachycardia syndrome (POTS), a condition where your heart rate rises when you stand. The study may help researchers understand what causes POTS and how it could be treated or monitored.
Oklahoma City, OklahomaAges 18–50 - NCT06289413Recruiting
Nervous system changes after weight-loss surgery
This study looks at how bariatric surgery affects the part of your nervous system that controls things like heart rate and blood pressure (autonomic function). It may help patients preparing for or recovering from weight-loss surgery.
Overland Park, KansasAges 18–85 - NCT06467825Recruiting
Sex differences in standing up after moon landing
This NASA trial tests how men and women differ in standing up after landing on the moon. Volunteers receive a water pill (furosemide) to see how their blood pressure and heart respond during simulated lunar descent and ascent.
Houston, TexasAges 25–55 - NCT06939153Recruiting
How age, sex, and exercise affect the heart when blood flow drops
This study looks at how your heart and blood vessels work together when blood flow to your legs is reduced using a special chamber. It compares younger and older adults, and men and women, especially after light exercise.
Boston, MassachusettsAges 18 years+

Common questions
- Are there clinical trials for orthostatic intolerance?
- Yes. Clin2 currently lists 8 recruiting orthostatic intolerance studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a orthostatic intolerance trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a orthostatic intolerance trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
