Abstract

We describe the case of a 22-year-old female who was diagnosed with a functional movement disorder. The diagnostic processes she underwent elegantly illustrates the practical utility and limitations of multi-channel electromyography/polymyography and EEG back-averaging in correlating with and demonstrating the clinical features of functional movement disorders, providing a vital avenue through which a clinician may find useful when navigating the imposing diagnostic minefield of functional movement disorders.
