Transcutaneous Electrical Acustimulation (TEA) for the Treatment of Non-Erosive Gastroesophageal Reflux Disease (NERD): A Multicenter, Randomized, Sham-Controlled Trial

This multicenter study aims to evaluate whether Transcutaneous Electrical Acustimulation (TEA) is effective in treating Non-Erosive Gastroesophageal Reflux Disease (NERD). NERD is a common condition where patients experience symptoms like heartburn and regurgitation, but no visible damage can be seen in the esophagus during an endoscopy. TEA is a non-invasive treatment that uses a small device to deliver mild electrical stimulation through the skin on specific acupoints. This study will compare the effects of real TEA treatment with a sham (inactive) control. Participants will be randomly assigned to one of two groups: active TEA treatment or sham stimulation. Neither the participants nor the researchers evaluating the outcomes will know which treatment is being given. The main outcome is the improvement of reflux symptoms after 4 weeks of treatment. The results of this study may provide a new non-drug option for patients suffering from NERD.
