Official Title: Subthalamic Deep Brain Stimulation in Patients With Medication-Refractory Primary Cranial-Cervical Dystonia: A Randomised, Sham-controlled Trial
Brief Summary: Primary cranial-cervical dystonia is managed mainly by repeated botulinum toxin injections.This study is to establish whether subthalamic nucleus neurostimulation could improve symptoms in patients not adequately responding to chemodenervation or oral drug treatment. Investigators compared this surgical treatment with sham stimulation in a randomized, controlled clinical trial.
