ABSTRACT Artículo en español English version
INTRODUCTION Orthostatic tremor is a rare kind of tremor which is clinically characterised by a feeling of instability or being about to fall that is experienced on standing up, which disappears or improves on walking and is absent when sitting or lying down.

AIM To shed light on the main features of this tremor syndrome. DEVELOPMENT. First, its clinical spectrum is defined, with emphasis on the key characteristics that enable us to make an initial approximation to its syndromes. Then the main neurophysiological features that make up the electromyographic profile of orthostatic tremor are described. Finally, the pathophysiological hypotheses regarding the genesis of this kind of tremor are addressed and the therapeutic options currently available are described.

CONCLUSIONS The convergence of all the data reviewed provides a complete, critical analysis of this enigmatic motor disorder, thus allowing a rigorous approach to its main characteristics, which makes both its clinical recognition and its therapeutic management easier.
