Sante Fe is an investigation of a new technique to distinguish between different types of movement disorders, specifically organic versus functional, by observing changes in involuntary movements in two different situations.

This study involves a short, one-time visit. Subjects will be asked to undergo a brief neurological examination while being video taped in two different scenarios. The severity of the abnormal movement will be analyzed and compared among subjects with functional (FMD) versus organic movement disorders (OrgMD).

Inclusion Criteria:

1. Patients with a clinical diagnosis of Functional Movement Disorder (e.g. functional tremor, functional dystonia, functional myoclonus) based on Fahn-Williams criteria or OrgMD (e.g. Parkinson disease, essential tremor, cervical dystonia) evaluated by a fellowship-trained movement disorder neurologist at Cleveland Clinic
2. Patients with mild to severe involuntary movement as a result of the movement disorder, visible for video-recording.

Exclusion Criteria:

1. Significant cognitive impairment that prevents proper informed consent
2. Patients whose movement disorders cannot be captured on video
