Proposed guidelines for videotaping individuals with movement disorders

Standardized rating scales for Parkinson's disease and dystonia have been validated and are now widely accepted as useful clinical assessment tools. However, the other movement disorders have been more difficult to quantify. The use of a standardized videotape protocol can provide a more precise audiovisual record of the movement disorder patient. With broader use by others and further revisions, these guidelines can be improved in order to provide an accurate assessment and teaching tool. The authors welcome comments.
