This study tests whether simple counterpressure maneuvers, like leg crossing or arm tensing, can help prevent fainting in children aged 6 to 18. Participants will either receive usual care or learn these techniques and be followed for one year. The goal is to see if these easy-to…

This study tests whether a non-invasive device that stimulates the vagus nerve can reduce stomach and bowel symptoms in children aged 10-18 with hypermobile Ehlers-Danlos syndrome (hEDS) and related autonomic nervous system problems. Researchers will measure changes in digestive …
