Resumos

Tremor ortostático (TO) é v.m novo tipo de tremor, irregular e de alta freqüência, recentemente descrito, que afeta grupamentos musculares antagonistas nos membros inferiores, desde que seja mantida a postura ereta. Descrevemos dois novos casos deste tipo peculiar de tremor, que pode não ser tão incomum quanto até então suposto. Enfatizamos suas principais características diagnosticas e semiológicas. O TO pode compartilhar algum mecanismo fisiopatológico básico com os tremores da variedade heredofamilial essencial clássica.

Orthostatic tremor (TO) is a recently described new type of a high frequency irregular tremor which affects antagonistic sets of muscles in the lower limbs only since the erect posture is maintained. We describe two other cases of this peculiar kind of tremor which may be not so uncommon as up to now realized and emphathize its main diagnostic and semeiological characteristics. TO may share some basic pathophysiological mechanism with tremors of the classical heredofamilial essential variety.
