A neurologist notices the physical benefits of the stimulation for each of the five test probes temporarily immersed on the targeted area (subtalamic region). The final electrode will be definitely implanted depending on the results. It is an electrical stimulation undertaken through an electrode placed at the level of a thalamic nucleus, the Ventral Intermediate Nucleus (VIM). This electrode is set up surgically, thanks to a nanopositioning system, after neuroradiological spotting, undertaken under 3D MRI, and neurophysiological by detection and recording of cellular activities. The electrode is linked to a programmable subcutaneous stimulator. The intervention can be bilateral. A quadripolar electrode, proposed after the initial notice of the CEDIT(Comitee for Evaluation and Diffusion of Innovative Technologies), has rapidly imposed to different teams using this technique ; the evacuation protocole has been amended accordingly.
