Brief Summary:
Dystonia is a group of movement disorders characterized by twisting, repetitive movements, or abnormal postures caused by involuntary muscle contractions and is characterized by a young age of onset and a high disability rate. Early intervention can reduce disability incidence, improve the patient's quality of life, and reduce the burden on families and society. Multiple international guidelines on dystonia have found deep brain stimulation (DBS) to be a safe and effective treatment for refractory dystonia. The globus pallidal internus (GPi) is the mostly widely used target for dystonia. However, there are limitations on the GPi DBS treatment, including slow onset of beneficial effects, poor improvement of axis symptoms, and potential stimulation-related side effects. Previous studies have described the highly successful use of subthalamic nucleus deep brain stimulation (STN DBS) in patients with refractory dystonia, suggesting that STN DBS is an effective and persisting alternative to pallidal deep brain stimulation. However, all STN DBS treated cases have been analyzed in open-label uncontrolled cohort studies, leading to limited data with a high level of evidence on the STN DBS in dystonia. Further, the investigators hypothesized STN has potentially more effectiveness when compared with GPi, and may be more power-saving and quick-acting. In this study, the investigators will organize a prospective randomized, double-blind, parallel-group, multicenter study comparing active versus sham stimulation in isolated segmental or generalized dystonia to evaluate the effectiveness and safety of STN DBS by measuring the impact on motor status, mental status, quality of life, the rate of response of the patients (the number of patients with ≥30% improvement in the movement score on the Burke-Fahn-Marsden Dystonia Rating Scale) and the rate of adverse events during the trial.
