Deep brain stimulation parameters for dystonia: A systematic review

•Stimulation parameters for dystonia are 3.3 V amplitude, 131 Hz frequency, and 120 μs, 210 μs, or 450 μs pulse widths.•Longer pulse widths are more common among generalized dystonia.•Shorter pulse widths are more frequently used in focal and acquired dystonia.•Some dystonia subtypes show improved clinical outcomes with specific pulse widths.
