Effects of tDCS Combined With CBI on Postsurgical Pain

Transcranial direct current stimulation (tDCS), stimulates specific areas of the brain via electric current passed through electrodes placed on the scalp. During tDCS, low amplitude direct currents penetrates the skull to enter the brain and modulates neuronal activity.

CBI generally consist of cognitive coping strategies (e.g., distraction, relabeling, reducing pain-catastrophizing) and self-management (e.g., relaxation strategies, guided imagery) designed to enhance perceived control and reduce sympathetic nervous system tone.
