Deep Brain Stimulation Motor Ventral Thalamus (VOP/VIM) for Restoration of Speech and Upper-limb Function in People With Subcortical Stroke

All participants enrolled in this group will undergo a surgical procedure to implant deep brain stimulation electrode leads. The electrodes will be connected to external stimulators and a series of experiments will be performed to identify the types of movements that the hand and arm can make and how speech abilities are affected by the stimulation. The implant will be removed after less than 30 days.
