Botox for Cervical Dystonia Following EMG Mapping

Summary

The purpose of this study is to determine how to improve treatment of patients with cervical dystonia who have not been helped with standard Botox injections. This study is for patients with cervical dystonia who have not benefited from treatment with Botox using conventional "single lead electromyographic (EMG) techniques" for injection. The study aim is to see if these patients may have significantly more benefit if their Botox is injected into muscles that have been chosen with a multi-channel EMG mapping study of the neck prior to Botox injection.
