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

The study is designed to assess the assistive effects of DBS (i.e., immediate effects when the stimulation is turned ON) and obtain preliminary evidence for therapeutic effects (i.e., long-lasting effects with stimulation OFF). Researchers will 1) quantify the ability to recruit face muscles with electrical stimulation of the motor thalamus in patients with subcortical stroke, 2) quantify the ability to recruit arm and hand muscles with electrical stimulation of the motor thalamus in patients with subcortical stroke, and 3) verify if the delivery of DBS has effects on the central nervous system with clinical measures.
