Summary
This study evaluates the effectiveness of a neurostimulator applied to the outer ear for adolescents with functional gastrointestinal disorders. The neurostimulator provides nerve stimulation to a branch of the vagus nerve which is thought to be involved in transmission of pain signals. Half of the study subjects will receive an active nerve stimulator while the other half will receive an inactive one.
