For all patients where dystonia is combined with other neurological or systemic features, some additional workup is warranted, regardless of the age at onset or body distribution. Here, the focus is on practical issues of relevance to any physician who may council patients regarding these options.

Many detailed resources are available for application of the BoNTs including target muscle selection, dosing, and the use of ancillary procedures for localization such as electromyography and ultrasound.

When a specific etiology cannot be determined, it is important to follow patients and revise the diagnosis as additional clinical features are recognized.
