Effect of Non-invasive Neuromodulation on the Quality of Bowel Cleansing: a Randomized, Controlled, Double-blind Clinical Study

To clarify whether non-invasive neuromodulation for assisted bowel preparation can improve the quality of bowel preparation, to explore the possible mechanisms by which TEA improves the quality of bowel preparation, and to assess its safety, as well as subjects' tolerance, compliance and satisfaction.
