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

The Cleveland Clinic40 enrolled

Overview

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).

Eligibility

Sex: ALL

Medical Language ↔ Plain English

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

Outcomes

Primary Outcomes

Change in Simplified Functional Movement Disorders Rating Scale (sFMDRS) score according to video raters between two conditions in FMD vs OrgMD patients.

Change in Simplified Functional Movement Disorders Rating Scale (sFMDRS) score according to video raters between two conditions in FMD vs OrgMD patients. Score reports total abnormal movement score ranging from 0-3 for 9 different regions of the body or body functions. Higher score implies more severe movement.

Time frame: Because this is a one-time visit study, outcome will be measured during the visit, data reported at study conclusion after successfully recruiting 40 subjects and completing analysis with projected finish date in 1 year

Secondary Outcomes

The difference in the numerical change in self-perception of movement severity between two conditions in FMD vs OrgMD patients

The difference in the numerical change in self-perception of movement severity, as measured by a Likert-style scale, between two conditions in FMD vs OrgMD patients. Self-perception is scored on a scale of 0-4, with a higher score indicating more severe abnormal movement.
