Summary

The purpose of this study is to assess the effects of high-definition transcranial direct current stimulation (HD-tDCS) on subjects with chronic musculoskeletal pain. The investigators hypothesize that subjects will show a decrease in pain symptoms in the active anodal stimulation group when compared to sham stimulation.

Conditions

• Chronic Pain

Interventions

Type	Name	Description
DEVICE	High Definition Transcranial Direct Current Stimulation (HD-tDCS)	Subject will receive active anodal/cathodal and sham HD-tDCS in a randomized, counterbalanced order. Each stimulation session will be separated by at least one week to avoid carryover effects. For both active and sham HD-tDCS the electrodes will be placed over the primary motor cortex, at an intensity of 2mA. * For active anodal stimulation, the anode will be over the primary motor cortex, and the cathodal electrodes (4) will surround the anode in a 3 inch square, duration will be 20 minutes. * For active cathodal stimulation, the cathode will be over the primary motor cortex, and the anodal electrodes (4) will surround the cathode in a 3 inch square, duration will be 20 minutes. * For sham stimulation, the same procedure will be used, however, current will only be active for 30 seconds (current ramping up, then ramping down)
