MOVEMENT DISORDERS
Participants underwent stereotactic implantation of a single DBS lead in the area of the cerebellar DN contralateral to the lesioned cerebral hemisphere using a frame-based technique similar to that used in DBS for movement disorders (Supplementary Fig. Between the rehab-only and the DBS + rehab phases, participants underwent up to 16 programming visits. First, a traditional monopolar review was performed to characterize stimulation-related side effects for each of the eight contacts of the DBS lead and delineate the upper limit of the parameter space. Thereafter, the acute effects of DN-DBS on motor task execution and task-related electroencephalography were examined according to specified combinations of electrode polarity, pulse frequency, pulse width and pulse amplitude.
