Study of the Ability of a New Technique to Effectively Diagnose Movement Disorders

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
