Objectives: To review the current evidence for cerebellar modulation in movement disorders and its safety profile. Methods: Eligible studies were identified after a systematic literature review of the effects of cerebellar modulation in cerebellar ataxia, Parkinson's disease (PD), essential tremor (ET), dystonia and progressive supranuclear palsy (PSP). Neuromodulation techniques included transcranial magnetic stimulation (TMS), transcranial direct current stimulation (tDCS) and deep brain stimulation (DBS). The changes in motor scores and the incidence of adverse events after the stimulation were reviewed. Results: Thirty-four studies were included in the systematic review, comprising 431 patients. The evaluation after stimulation ranged from immediately after to 12 months after. Neuromodulation techniques improved cerebellar ataxia due to vascular or degenerative etiologies (TMS, tDCS and DBS), dyskinesias in PD patients (TMS), gross upper limb movement in PD patients (tDCS), tremor in ET (TMS and tDCS), cervical dystonia (TMS and tDCS) and dysarthria in PSP patients (TMS). All the neuromodulation techniques were safe, since only three studies reported the existence of side effects (slight headache after TMS, local skin erythema after tDCS and infectious complication after DBS). Eleven studies did not mention if adverse events occurred. Conclusions: Cerebellar modulation can improve specific symptoms in some movement disorders and is a safe and well-tolerated procedure. Further studies are needed to lay the groundwork for new researches in this promising target.engrestrictedAccessCerebellumDeep brain stimulationDirect current stimulationMovement disordersNeuromodulationTranscranial magnetic stimulationtheta-burst stimulationtranscranial magnetic stimulationlevodopa-induced dyskinesiasprogressive supranuclear palsyparkinsonian resting tremordeep brain-stimulationhuman motor cortexcervical dystoniawriters crampspinocerebellar degenerationarticleCopyright ELSEVIER SCIENCE INC10.1016/j.brs.2017.11.015Clinical NeurologyNeurosciences1876-4754
