Cerebellar Deep Brain Stimulation or VNS for Chronic Post-stroke Motor Rehabilitation
Sponsor: Qilu Hospital of Shandong University
Summary
Upper-extremity impairment after stroke remains a major therapeutic challenge and a target of neuromodulation treatment efforts.In this open-label, randomized phase I trial, we applied deep brain stimulation to the cerebellar dentate nucleus combined with bilateral or unilateral stimulation. Vagus nerve stimulation was also conducted for motor function after ischaemic Stroke.We hypothesized that cerebellar stimulation was superior to vagus stimulation as the motor rehabilitation after stroke benefits from both side of cerebellum.

Interventions
Bilateral Cerebellar deep brain stimulation
Participants underwent stereotactic implantation of a single DBS lead in the area of the cerebellar DN contralateral to the lesioned cerebral hemisphere using a frame-based technique similar to that used in DBS for movement disorders. All participants received an 4-channel lead (Medtronic,3389）with electrode arrays up to 15.5 mm in length. Then bilateral stimulation was activated after 1 month post-DBS
Unilateral Cerebellar deep brain stimulation
Participants underwent stereotactic implantation of a single DBS lead in the area of the cerebellar DN contralateral to the lesioned cerebral hemisphere using a frame-based technique similar to that used in DBS for movement disorders. All participants received an 4-channel lead (Medtronic,3389）with electrode arrays up to 15.5 mm in length. Then unilateral stimulation was activated after 1 month post-DBS
Vagus Nerve Stimulation
Device implantation was done under general anaesthesia. A horizontal neck crease incision was created left of the midline at the level of the cricoid cartilage. After the vagus nerve was identified, the stimulation lead was wrapped around the vagus nerve. The lead was then tunnelled subcutaneously to the pulse generator device which was contained in a subcutaneous pocket in the pectoral region.
