For these reasons, non-invasive brain stimulation (NIBS) techniques, namely transcranial direct current stimulation (tDCS) might be of help in this context. tDCS is a new NIBS technique with a good safety profile, easy implementation, good patients' tolerance and little or no adverse effects. tDCS uses low levels of constant current delivered to specific brain area via sponge electrodes placed on the scalp. tDCS modifies the polarization of the exposed neuronal circuits. Indeed, it modulates the spontaneous neuronal excitability and activity by a tonic depolarization or hyperpolarization of resting membrane potential.
Therefore, applying a home-based intervention is of interest in a population suffering from high levels of physical disability prohibiting them from frequently coming to seek care at the hospital
