Background: Quantitative and objective neurophysiological assessment can help to define the predominant phenomenology provide diagnoses with prognostic therapeutic implications. We evaluated retrospectively indications final of movement disorder evaluations in a specialized disorders centre. Methods: Reports from 2003 11/2021 were reviewed. The classified according phenomenology, diagnosis each study was categorized subgroups phenomenology. Results: A total 525 reports evaluated. mean age patients 51 years (range 5 – 89 years), 50% women. most common indication functional (33%), followed by jerky movements (25%), tremor (20%), unsteadiness (6%), stiff person syndrome (4%), other less (12%). prevalent (37%), (28%), comprising essential dystonic (5%), cerebellar parkinsonian (3%) types tremors (10%); myoclonus (21%), including cortical (8%), subcortical undefined (10%) types. Conclusions: This 17-year experience showed that testing disorders. More standardized techniques will encourage widespread use neurophysiology evaluate
