Transcranial Direct Current Stimulation (tDCS) is a form of brain stimulation which allows for the selective increase or decrease in the cortical excitability of a targeted region. When applied over the motor cortex it has been shown to induce changes in cortical and subcortical brain regions involved in descending pain inhibition or Conditioned Pain Modulation (CPM).The aim of the current study was to assess whether activation of pain inhibitory pathways via tDCS of the motor cortex facilitates the CPM response.
