Observing movement disorders: best practice proposal in the use of video recording in clinical practice.

Clinical evaluation is of utmost importance in the semeiological description of motor disorders which often require video recording to highlight subtle signs and their subsequent evolution. After reviewing 1858 video recordings, we composed a suitable list of video-documentation maneuvers, classified semeiologically in the form of a "video recording protocol", to guarantee appropriate documentation when filming movement disorders. Aware that our proposed filming protocol is far from being exhaustive, by suggesting a more detailed documenting approach, it could help not only to achieve a better definition of some disorders, but also to guide neurologists towards the correct subsequent examinations. Moreover, it could be an important tool for the longitudinal evaluation of patients and their response to therapy. Finally, video recording is a powerful teaching tool as visual teaching highly improves educational training.
