Randomized Controlled Trial
The effects of transcranial direct current stimulation in patients with neuropathic pain from spinal cord injury.
Transcranial direct current stimulation (tDCS) has demonstrated efficacy for reducing neuropathic pain, but the respective mechanisms remain largely unknown. The current study tested the hypothesis that pain reduction with tDCS is associated with an increase in the peak frequency spectrum density in the theta-alpha range. ⋯ The results provide new findings regarding the effects of tDCS on neuropathic pain and brain oscillation changes.
