Bipolar Directional Deep Brain Stimulation in Essential and Parkinsonian Tremor

ConclusionsSide ‐effect thresholds of monopolar directional and bipolar stimulation with both circular and directional anodes were higher compared to traditional monopolar circular stimulation in the VIM. Bipolar DBS with directional anodes evoked side‐effect less frequently than bipolar and monopolar direction al stimulation. All stimulation settings had comparable effects on tremor suppression just below their side‐effect thresholds. Thus, directional and different bipolar settings should be explored in patients with bothersome side‐effects of thalamic stimulation when monopolar stimulation settings are not satisfying. Further studies are needed to explore the efficiency of the different bipolar stimulation paradigms.
