**1. Introduction**

Neuromodulation is an increasingly rising field in the successful treatment of neurological disorders [1, 2]. Neurostimulation allows highly flexible alteration of disease symptoms. A number of medications fail due to severe side effects that outweigh the medication benefit, but neurostimulation has been so long to be potentially used as a treatment option for several movement disorders [2], with mild side effects with unknown mechanism of action in other disorders [3].
