IB-STIM for Patients with Disorders of Gut Brain Interaction (DGBIs)

IB-STIM is a small electrical device worn behind the ear that stimulates cranial nerves to help reduce abdominal discomfort in patients with Disorders of Gut Brain Interaction (DGBIs), such as functional abdominal pain, irritable bowel syndrome, and functional dyspepsia, in adolescents 11 to 18 years old. 

Learn more about these conditions

How IB-STIM works

The device is taped behind one ear and emits gentle electrical pulses which stimulates certain areas of the brain that process pain and reduce pain signaling. The device has four wires that your child’s specialist places near nerve bundles on the external ear surface. Patients wear the IB-STIM device for 120 hours (5 days) consecutively with a two-day break. This is repeated for a duration of 4 weeks.

Who can benefit from IB-STIM

IB-STIM helps adolescent patients with Disorders of Gut Brain Interaction (DGBIs) but may not be recommended for all children with these conditions. Many patients have seen a decrease in abdominal pain and other symptoms within a few weeks of wearing the device. The device is not recommended for patients with a pacemaker, hemophilia or a skin condition called psoriasis vulgaris.
