Limitations and future directions
This work has some limitations, which should be taken into account. This is a single-session proof-of-principle study, which did not aim to optimize stimulation protocols to achieve maximal effects. Adaptation of the protocol, including stimulation area, intensity, duration, number of sessions, and adaptation of the intervention protocol to task characteristics might enhance efficacy further. In previous studies, multi-session compared to single-session interventions have been shown to be more efficient
