A dissociation between subjective and objective unsteadiness in primary orthostatic tremor.
Patients with primary orthostatic tremor (OT) experience a disabling sense of unsteadiness but rarely fall. In order to study the relationship between the development of subjective unsteadiness, objective unsteadiness and tremor, we recorded standing under four conditions (eyes open or closed, feet together or apart) in six patients with OT. Subjective unsteadiness was indicated by the patients...
متن کاملA Slow Orthostatic Tremor of Primary Origin
BACKGROUND Orthostatic tremor (OT) is a high-frequency tremor (13-18 Hz) present in the legs when standing. Underlying disease is found in one-third of OT patients. CASE REPORT We describe an 86-year-old man with progressive shaking of the legs while standing, which disappears immediately after sitting down or while walking. Polymyography confirmed a tremor of the legs (10-11 Hz) while standi...

متن کاملPathogenesis of Primary Orthostatic Tremor: Current Concepts and Controversies
Background Orthostatic tremor (OT), a rare and complex movement disorder, is characterized by rapid tremor of both legs and the trunk while standing. These disappear while the patient is either lying down or walking. OT may be idiopathic/primary or it may coexist with several neurological conditions (secondary OT/OT plus). Primary OT remains an enigmatic movement disorder and its pathogenesis a...
متن کاملForce platform recordings in the diagnosis of primary orthostatic tremor.
Primary orthostatic tremor (OT) consists of rhythmical muscle contractions at a frequency of around 16 Hz, causing discomfort and/or unsteadiness while standing. Diagnosis has hitherto relied on recording Electromyography (EMG) from affected muscles. The main aim of this study was to see if the characteristic postural tremor in OT can be identified with force platforms. We also quantified postu...
