Transcutaneous Electrical Acustimulation (TEA) for Gastroparesis

The device being studied, the Transcutaneous Electrical Accustimulator (TEA), will deliver weak electrical current at two specific points, one at the leg and the other at the arm at settings known to improve symptoms involving the digestive system. The study team would like to test if the device will impact the gastrointestinal (GI) symptoms and gastric motility in study participants with gastroparesis.
