Transcutaneous Electrical Acustimulation (TEA) for Gastroparesis

This study aims to assess if the device will impact the (GI) symptoms and gastric motility in study participants with gastroparesis. This will be done over a 12 week period during which each participant will undergo two visits. There will be two total visits that each follow the same schedule. During the first visit, subjects will undergo a 3-in-1 gastric functional test which is a non-invasive method to assess the gastric motility and visceral pain. This test will entail an EGG, ECG, and water satiety drink test for gastric accommodation. Following the 3-in-1 gastric functional test, subjects will be randomized and trained on how to use the study device. Half of the patients will be assigned to the sham group and half will be assigned to the treatment group. Each group will undergo 8 weeks of treatment or 8 weeks of sham stimulation and will receive weekly calls from the study team to check for adverse events and study compliance. Following the first 8 week period, subjects will return to the study site to undergo visit two. This will follow the same format as visit 1. At this time, subjects will become unblinded. Those who received sham stimulation will be trained on the correct locations for each TEA device and will receive an additional 4 weeks of treatment with the device. Note: The gastric emptying breathalyzer test (GEBT) was removed, and the two-day visits were shortened to one-day to improve patient recruitment and retention.
