Comparing the effect of transcranial random noise stimulation and transcranial direct current stimulation over the motor cortex on motor performance in men vs. women: a randomized controlled crossover study.

(2015) found that the perceived sensations during sham and real tRNS conditions were indistinguishable, whereas the difference between anodal tDCS and sham was marginally significant ( p = 0.056).

From a behavioral perspective, both hf-tRNS and ctDCS over M1 showed a trend toward improvements in error rates, while lf-tRNS exhibited a trend toward hindering error rates in a visuomotor task.
