A Study of Randomized Sham-control Auricular TENS Unit Stimulation in Pediatric Functional Gastrointestinal Disorders
A Study of Randomized Sham-control Auricular TENS Unit Stimulation in Pediatric Functional Gastrointestinal Disorders
The purpose of this study is to see if using a micro-current through a device called a TENS
 (Transcutaneous Electrical Nerve Stimulator) unit helps to improve functional
 gastrointestinal disorder (FGID) symptoms in children by stimulation of the vagus nerve. The
 study will compare two methods of stimulation to determine if there is a difference in the
 two methods.
