We will apply sham tDCS on the primary motor cortex. We will use the same montage and parameters of active tDCS. However the current will be applied for 30 seconds in the beginning of the procedure and after that the current is turned off. This parameter for sham stimulation was chosen based on previous studies that have shown that perceived sensations on the scalp such as tingling usually fade out in the first 30 seconds of tDCS. It should be noted that less than 3 minutes of tDCS induces no effects on cortical excitability [29] and also using 30 seconds of sham is a reliable method of blinding as shown by a randomized controlled study [30]. Subjects will also meditate while receiving stimulation

A 1x1 Low-intensity DC Stimulator such as the Soterix Medical Inc. (Model 1224-B New York, NY, USA) or an equivalent device will be used to deliver direct current through 35cm² saline-soaked electrodes. The anodal electrode will be placed over the left primary motor cortex (M1) while the cathodal electrode will be placed over the contralateral supra-orbital area. Primary motor cortex will be localized using the 10/20 EEG system (C3 or C4) and this is a reliable method for the technique of tDCS [5]. During active tDCS, a 2mA constant current will be delivered for 20 minutes while the subject meditates. The primary motor cortex is a reliable "entry port" to modulate dysfunctional activity in pain-related neural networks.

Assess the effects of 5 days of active vs sham tDCS stimulation plus meditation on chronic visceral pain in patients with chronic pancreatitis. We will determine the magnitude of pain reduction using the Visual Analog Scale (VAS) score and Brief Pain Inventory (BPI). We hypothesize that active tDCS plus meditation will have a greater decrease in VAS scores and BPI scores when compared to sham tDCS plus meditation in subjects with chronic pancreatitis

Assess the effects of 5 days of active vs sham tDCS stimulation plus meditation on life satisfaction in subjects with chronic pancreatitis. We will use the Quality of Life Scale (QoLS) to assess changes in life satisfaction after active tDCS plus meditation intervention. We hypothesize that active tDCS plus meditation will have a greater increase in the QoLS after the intervention when compared to sham tDCS plus mediation in subjects with chronic pancreatitis

Determine whether treatment with active tDCS coupled with meditation changes cortical activity as assessed with electroencephalography (EEG). We hypothesize that active tDCS plus meditation will have a greater increase in alpha activity and a greater inhibition in beta activity and this will be associated with a greater reduction in pain when compared to sham tDCS plus meditation in patients with chronic pancreatitis.
