Role of Home-Based Transcutaneous Electrical Acustimulation for Treatment of Pain in Subjects With Chronic Pancreatitis

Active TEA or sham TEA will be self-administered at home over two daily treatment sessions of 30 minutes each in the morning and evening. Active TEA will be delivered through an active stimulation acupoint that has previously shown to reduce abdominal pain in other patient populations. Sham TEA will be administered at a different point a few cm away from the active site and that has been shown to be ineffective in reducing pain. Other than the location, the anatomical location, application of TEA and sham will be identical. The device will be programmed by the study team to generate fixed frequency, pulse width, and time on/time off during the pulsed stimulation. The subject is only able to change the stimulation output in a range from 0-10 milliampere.
