Efficacy and Safety of Deep Brain Stimulation in Mesencephalic Locomotor Region（MLR） for Poststroke Hemiplegia

"An elaborate target/trajectory planning and a precise image fusion of MRI and stereotactic CT scanning are performed before surgery. After microelectrode recording, two sets of quadripolar DBS leads (contact interval is 1.5mm) will be inserted into theMLR. Subsequently, an implantable pulse generator will be connected via extension wires and implanted at the left/right subclavicular area subcutaneously. Device: MLR-DBS devices~(1) DBS electrode: 3387 (Medtronic, Minneapolis, MN, USA) or L302 (PINS Medical, Beijing, China) or 1210(SceneRay, Suzhou, China); (2) Extension wire: 37086 (Medtronic, Minneapolis, MN, USA) or E202 (PINS Medical, Beijing, China) or 1340/SR1341 (SceneRay, Suzhou, China); (3) Implantable pulse generator: ACTIVA PC/RC (Medtronic, Minneapolis, MN, USA) or G102/G102R (PINS Medical, Beijing, China) or 1180/SR1101 (SceneRay, Suzhou, China)."
