Stimulation of the Dentate Nucleus of the Cerebellum for the Treatment of Refractory Spasticity With or Without Dystonia

To establish anatomical and functional criteria, based on stereotactic imaging and electrophysiological recordings, that enable the precise implantation of electrodes in the DN and its efferent projections for the treatment of movement disorders. This study aims to describe a surgical technique for the implantation of deep brain electrodes targeting the stimulation (DBS) of the dentate nucleus (DN) and its efferent projections, supported by the magnetic resonance imaging (MRI), the diffusion tensor imaging (DTI), reformatted in the stereotomographic images and related to stereotactic landmarks and checked with semimicro deep brain recording.
