To date, protocols that have used home-based tDCS have started with an in-person training session, either a home visit from a technician or a visit to the research facility by the subject. This was done to ensure that the individuals understood and properly used it (Kasschau et al., 2016). In the context of stricter social isolation situations such as a quarantine or complete lockdown, future protocols could potentially use solutions with all the instruction and orientation sessions done remotely, but that would require testing for feasibility.
