Transcutaneous spinal random noise stimulation enhances motor memory consolidation and corticospinal transmission in humans.

ABSTRACT: Stochastic resonance sensory input modulates the central nervous system's excitability, thereby possibly influencing motor skill learning and retention. We investigated the effects of transcutaneous spinal random noise stimulation (tsRNS) at the cervical level on motor skill learning and corticospinal transmission in healthy humans. Participants performed a 20 min visuomotor tracking training task requiring rapid shifts in pinch force, with motor performance tests conducted before, immediately after, 1 day after and 7 days after the training to assess motor skill learning and retention. During the task, participants received real or sham tsRNS for 20 and 0.5 min, respectively. Motor performance improved equally in both groups immediately after training; however, the real tsRNS group showed
