Effects of combining 2 weeks of passive sensory stimulation with active hand motor training in healthy adults.

The gold standard to acquire motor skills is through intensive training and practicing. Recent studies have demonstrated that behavioral gains can also be acquired by mere exposure to repetitive sensory stimulation to drive the plasticity processes. Single application of repetitive electric stimulat...
