Treatment for Psychogenic Disorders

Objective: To apply respiratory biofeedback to patients with Psychogenic Movement Disorders (PMD) with a goal of decreasing involuntary movements. Study Population: Patients diagnosed with "clinically definite" PMD based on the Fahn-Williams scale Design: Open-label pilot study Outcome measures: * To evaluate a possible decrease or resolution in involuntary movements caused by PMD as measured by the Psychogenic Movement Disorder Scale. Videotaping will be performed pre- and post-treatment and the videos will be evaluated by movement disorder specialists who are blinded to the pre-treatment or post-treatment condition. * To evaluate if respiratory biofeedback is an effective treatment for patients with PMD. * To retrospectively evaluate the components of anxiety and depression with responders versus non-responders.
