Somatosensory and transcranial direct current stimulation effects on manual dexterity and motor cortex function: A metaplasticity study

Non-invasive neuromodulation may provide treatment strategies for neurological deficits affecting movement, such as stroke. For example, weak electrical stimulation applied to the hand by wearing a “mesh glove” (MGS) can transiently increase primary motor cortex (M1) excitability. Conversely, transcranial direct current stimulation with the cathode over M1 (c-tDCS) can decrease corticomotor excitability.Objective/Hypothesis: We applied M1 c-tDCS as a priming adjuvant to MGS and hypothesise d metaplastic effects would be apparent in improved motor performance and modulation of M1 inhibitory and facilitatory circuits.
