[Orthostatic tremor inducing instability].
Orthostatic tremor (OT) is a neurological disease of unknown aetiology. It is defined by the presence of a 10-20 Hz tremor in the legs while standing still.

متن کاملOrthostatic tremor: a cerebellar pathology?
SEE MUTHURAMAN ET AL DOI101093/AWW164 FOR A SCIENTIFIC COMMENTARY ON THIS ARTICLE: Primary orthostatic tremor is characterized by high frequency tremor affecting the legs and trunk during the standing position.

متن کاملEvidence for a non-orthostatic origin of orthostatic tremor.
OBJECTIVES Orthostatic tremor was first described by Heilman in 1984. It usually occurs in the legs during stance and decreases markedly during sitting or walking. The aim of this study was to determine if orthostatic tremor is invariably associated with the orthostatic and weight bearing conditions in the arms and legs, and to investigate the features of orthostatic tremor under different leve...
متن کاملOrthostatic tremor: a review of 45 cases.
OBJECTIVE To evaluate the clinical characteristics, associated features, and treatment response of a large orthostatic tremor series seen over a 26-year period. METHODS We reviewed the medical records of 45 patients seen between 1987 and 2013 who fulfilled the diagnostic criteria for orthostatic tremor. RESULTS The mean age at onset was 59.5 years and 23/45 (51%) were men. A family history ...
متن کاملCharacterizing Orthostatic Tremor Using a Smartphone Application
BACKGROUND Orthostatic tremor is one of the few tremor conditions requiring an electromyogram for definitive diagnosis since leg tremor might not be visible to the naked eye. PHENOMENOLOGY SHOWN An iOS application (iSeismometer, ObjectGraph LLC, New York) using an Apple iPhone 5 (Cupertino, CA, USA) inserted into the patient's sock detected a tremor with a frequency of 16.4 Hz on both legs. ...
