The Fahn, Tolosa e Marín's clinical rating scale for tremor was adapted to our country for evaluation of tremor. This scale was applied to 123 patients with this movement disorder, selected from the Ambulatory of General Medicine at Hospital Universitário Pedro Ernesto da Universidade do Estado do Rio de Janeiro. These patients had been chosen no matter the etiology of their condition or their age. Although some variants may had influenced the scores of this particular scale, they did not seem to change its standardization and applicability.
