Transcranial direct current stimulation(tDCS) is a non-invasive treatment that reduces neural activity. Recently, a clinical research study using a randomized, double-blind trial of tDCS on spinal cord patients found that it significantly reduced neuropathic pain for up to 12 weeks after treatment.
Although tDCS significantly reduced pain on its own, when combined with visual illusion-another therapy in which patients are placed in front of videos and mirrors to create an illusion of walking-patients showed the most significantly reduced neuropathic pain. Both tDCS and visual illusion are well-tolerated with minimal side effects, and should be considered as an alternative to other pain reducing therapies.
