The Use of tDCS in the Orofacial Pain

Transcranial Direct Current Stimulation (tDCS) is a non-invasive neuromodulatory method utilizing weak electrical currents to elicit short and long-term central nervous system changes.

The sham was administered using the same tDCS devices as in the active group with a preprogrammed sham protocol of 20 minutes to be virtually indistinguishable from the active stimulation.
