Effectiveness of cathodal tDCS of the primary motor or sensory cortex in migraine: A randomized controlled trial.

Objectives: Transcranial Direct Current Stimulation (tDCS) is a new technology that is extensively used for migraine treatment. The present study aims to examine the effectiveness of cathodal-tDCS (c-tDCS) in decreasing migraine pain frequency, duration, and intensity at the right primary motor cortex (M) or sensory cortex (S) in individuals with episodic or chronic migraine.

Methods: The present study has a randomized, single-blind, and sham-controlled design.
