In the researchers' words
A novel multisite high definition tDCS (HD-tDCS) in healthy people showed that such network-targeted stimulation could enhance motor excitability beyond traditional stimulation which targeting only one region. It showed that the excitability following multisite HD-tDCS was more than double the increase following conventional tDCS. To consider the various lesion site of different stroke survivors. The electrode placements based on personalized lesion profiles and anatomical features can be determined using finite element modeling, with lesion profiles generated from fMRI and advanced algorithms calculating the current density to maximize the modulation effect. Combining motor network interaction and the new multisite electrode montage may further provide a potential to facilitate stroke recovery.
