Deep brain stimulation parameters for dystonia: A systematic review

Despite anecdotal reports using low frequencies or pulse widths and variability in DBS stimulation parameters required to treat dystonia, there is consistency in amplitude and frequencies utilized. Some dystonia subtypes may improve with specific pulse widths. This review emphasizes the importance of complete data reporting in the literature and suggests that large prospective controlled blinded studies and international registries are needed to understand and optimize DBS settings for dystonia.
