The impact of transcutaneous electrical acustimulation (TEA) on rectal distension‐induced pain in patients with irritable bowel syndrome (IBS)—A study to determine the optimal TEA delivery modalities and effects on rectal sensation and autonomic function

TEA at ST36-100 Hz is superior stimulation point/parameter, compared to TEA at PC-6/sham-TEA, to reduce rectal distension-induced pain in IBS-C patients. This therapeutic effect appears to be mediated through rectal hypersensitivity reduction and autonomic function modulation.
