The Effects of Transcranial Direct Current Stimulation on Central Pain in Patients With Spinal Cord Injury

July 12, 2013 updated by: Hyung-Ik Shin, Seoul National University Bundang Hospital

The Analgesic Effect of Transcranial Direct Current Stimulation Over the Primary Motor Cortex on Central Neuropathic Pain Patients With Spinal Cord Injury

The purpose of this study is to evaluate the analgesic effect of transcranial direct current stimulation (tDCS) applied on motor cortex in patients with spinal cord injury who have chronic neuropathic pain.
