Brain and Peripheral Electrical Stimulation in Chronic Low Back Pain: a Factorial Design

Technique based on the application of weak, direct electrical current to the brain through relatively large electrodes that are placed over the scalp, in which anodal and cathodal stimulation increases and decreases cortical excitability, respectively

Technique based on the application of low-voltage electrical current to the skin through relatively large electrodes that are placed over the pain area.
