Abstract

Objectives: Orthostatic tremor is a specific form of tremor which is characterized by
a subjective feeling of unsteadiness during stance, not present in other positions. The
diagnosis can be confirmed in the electromyographic or accelerometric study by recor-
ding the tremor (e.g. in the quadriceps muscle) of frequency 13–18 Hz occurring exclusi-
vely in the upright position. Case report: In the present case, despite the presence of
the classic features of orthostatic tremor the proper diagnosis has been much delayed.
Conclusions: The paper presents the characteristic features of this rare movement disor-
der, indicates some diagnostic possibilities, and emphasizes the need for disseminating
the knowledge about the disease which can be treated successfully.
