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.
- INCLUSION CRITERIA: - Clinically definite functional (psychogenic) movement disorder as defined by Fahn and Williams criteria diagnosed by a movement disorder neurologist. - Patients who are at least 18 years old - Able and willing to cooperate with the study requirements EXCLUSION CRITERIA: - Any underlying major medical or neurological conditions - Patients whose movements are related to a known neurological disorder - History of traumatic brain injury or history of strokes - Current suicidal ideation - Patients with a psychotic disorder - Patients with active substance abuse within the last 6 months - Patients with moderate to severe depression, Beck Depression Inventory (BDI) greater than 18) - Patients with any ongoing litigation related to their diagnosis of PMD. - Patients with a definite overt stressor identified that is thought to be primarily responsible for the PMD symptoms
