5. Study Description

Brief Summary
Chronic pain patients with implanted dorsal root ganglion stimulators will be randomized to receive transcranial direct current stimulation (tDCS) to the motor cortex, magneto-encephalographically (MEG) localized stimulation or sham stimulation to identify therapeutic efficacy of paired central and peripheral neuromodulation.

Intervention Name(s)
Transcranial direct current stimulation
Other Intervention Name(s)
tDCS
Intervention Description
tDCS produces hyper/hypopolarizing potentials in the cortex underlying the scalp electrodes and can increase/decrease the excitability of targeted brain regions.
