The DMRF is gathering input from people with cervical dystonia (CD) about how their botulinum neurotoxin (BoNT) treatments are guided—particularly looking at the use of ultrasound (US) versus electromyography (EMG). The brief survey asks about your treatment setting, whether your provider uses EMG or US, and how treatment areas are determined. Even if you’re not currently treated with BoNT, there's an option to let us know. Your feedback will help inform clinical understanding and future research. Your participation is greatly appreciated.
