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.
This study tests a procedure called cardioneuroablation, which uses targeted heat (radiofrequency) to calm overactive nerves that cause your heart to beat too slowly and make you faint. The goal is to stop severe fainting spells in people with reflex syncope who haven't gotten better with other treatments.

It aims to reduce fear and avoidance so they can manage their medical care more easily.
This study uses brain scans to help people with animal phobias reduce their fear without consciously trying. It tests a new method that may make fear responses weaker over time.
This study tests different ways to make blood collection less painful and less scary for children. It compares methods like cooling the skin or using a simulation toy to see which works best.
