Transcutaneous electrical acupoint stimulation helpful in functional dyspepsia
A pilot study conducted by a group of American and Chinese researchers suggests that transcutaneous electrical acupoint stimulation (TEAS) can improve dyspeptic symptoms and gastric emptying time in patients with functional dyspepsia. Thirty patients with postprandial distress syndrome were randomly assigned to receive either TEAS or sham-TEAS treatment for four weeks. Compared with sham-TEAS, TEAS was found to improve dyspeptic symptoms, including initial satiety volume and maximum tolerable volume. Gastric emptying time was not affected by either treatment. Additionally, the TEAS treatment was found to increase vagal activity and decrease the sympathovagal ratio assessed by HRV. Expression of the proinflammatory cytokine Interleukin (IL)-6 in duodenal mucosa was downregulated after the TEAS treatment compared with baseline.
