Things have moved on from there and luckily we now have a randomised controlled trial with a sufficient sample size (n=135) of patients suffering from chronic low back pain and shown that tDCS – at least in this population and using a paradigm of 2mA for 20 mins on 5 consecutive days over the motor cortex – does nothing to reduce the perceived intensity of back pain or the disability associated with chronic low back pain (Luedtke et al., 2015). The results were not only not statistically significant, there wasn’t even a trend into the right direction

Neurobiological Effects of Transcranial Direct Current Stimulation: A Review
The purpose of this systematic review is to summarize the current knowledge regarding the neurobiological mechanisms involved in the effects of tDCS.

Neuroenhancement of the aging brain: restoring skill acquisition in old subjects.
The main finding was that old participants experienced substantial improvements when training was applied concurrent with tDCS, with effects lasting for at least 24 hours.

Examining transcranial direct-current stimulation (tDCS) as a treatment for hallucinations in schizophrenia.
Auditory verbal hallucinations were robustly reduced by tDCS relative to sham stimulation…

Modulation of training by single-session transcranial direct current stimulation to the intact motor cortex enhances motor skill acquisition of the paretic hand.
tDCS facilitated the acquisition of a new motor skill compared with sham stimulation…

Interactions between transcranial direct current stimulation (tDCS) and pharmacological interventions in the Major Depressive Episode: Findings from a naturalistic study.
tDCS over the DLPFC acutely improved depressive symptoms…

Amelioration of cognitive control in depression by transcranial direct current stimulation.
Deficient cognitive control over emotional distraction is a central characteristic of major depressive disorder (MDD)
The present study demonstrates that anodal tDCS applied to the left dlPFC improves deficient cognitive control in MDD.

Transcranial direct current stimulation of the motor cortex in the treatment of chronic nonspecific low back pain: a randomized, double-blind exploratory study.
No significant effect was seen in the primary outcomes between active and sham stimulation

Comparing immediate transient tinnitus suppression using tACS and tDCS: a placebo-controlled study.
…bifrontal tDCS modulates tinnitus annoyance and tinnitus loudness, whereas individual alpha-modulated tACS does not yield a similar result.

Review of transcranial direct current stimulation in poststroke recovery.
In this review, we summarize characteristics of tDCS (method of stimulation, safety profile, and mechanism) and its application in the treatment of various stroke-related deficits, and we highlight future directions for tDCS in this capacity.
