Clinical Trial Summary

This study will be a single-centre, prospective, single-arm, open-label pilot trial assessing the feasibility and safety of unilateral MR-guided focused ultrasound (MRgFUS) thalamotomy for refractory hand tremor in up to 12 patients with multiple sclerosis (relapsing-remitting, primary progressive or secondary progressive MS). This study will be conducted at the Focused Ultrasound Centre of Excellence and MS Clinic located at Sunnybrook Health Sciences Centre/ University of Toronto. Patients with stable MS and refractory hand tremor providing informed consent will receive MRgFUS thermal ablation of the Vim thalamus contralateral to the most affected side of the body (frequently this will be the dominant hand).
