RT Journal Article SR Electronic T1 Orthostatic tremor JF Practical Neurology JO Pract Neurol FD BMJ Publishing Group Ltd SP 240 OP 243 DO 10.1136/practneurol-2011-000022 VO 11 IS 4 A1 Jones, Leah A1 Bain, Peter G YR 2011 UL http://pn.bmj.com/content/11/4/240.abstract AB Orthostatic tremor is characterised by a feeling of unsteadiness that is accompanied by a high frequency (13–18 Hz) tremor of the legs when standing, and which is relieved by sitting or walking. We describe a typical patient whose condition gradually progressed so that eventually he could no longer stand still. We discuss the clinical features, management and pathogenesis, and highlight the need for awareness of this condition because the diagnosis is often missed or delayed.
