Patients stand on a wide base but walk normally. These symptoms are due to high\u2010frequency (13\u201318 Hz) burst firing in weight\u2010bearing muscles. They are attenuated by walking and are abolished immediately by sitting. Some authors believe that the disorder is a variant of essential tremor. This study reports the clinical and electrophysiologic features of orthostatic tremor in 30 patients. The findings indicate that orthostatic tremor is distinct from essential tremor, both clinically and electrophysiologically. The major differences are the frequency of electromyographic burst firing, the invariable involvement of lower limb and paraspinal muscles, and the task\u2010specific nature of the tremor in orthostatic tremor. The study shows that the diagnosis can be established rapidly with surface electromyographic recordings. \u00a9 1993 John Wiley &amp; Sons, Inc.<\/jats:p>","DOI":"10.1002\/mus.880161117","type":"journal-article","created":{"date-parts":[[2005,1,1]],"date-time":"2005-01-01T10:40:50Z","timestamp":1104576050000},"page":"1254-1260","source":"Crossref","is-referenced-by-count":91,"title":["Orthostatic tremor: Clinical and electrophysiologic characteristics"],"prefix":"10.1002","volume":"16","author":[{"given":"Philip G.","family":"McManis","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frank W.","family":"Sharbrough","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2004,10,13]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF00839142"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.52.1.130-a"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870060111"},{"key":"e_1_2_1_5_2","doi-asserted-by":"crossref","first-page":"15","DOI":"10.1007\/978-1-349-06757-2_2","volume-title":"Movement Disorders: Tremor","author":"Gresty MA","year":"1984"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.1984.04050190086020"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1097\/00002826-198708000-00004"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870030201"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-349-06757-2_14"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.1986.00520060048016"},{"key":"e_1_2_1_11_2","first-page":"304","article-title":"Shaky\u2010legs syndrome","volume":"4","author":"Veilleux M","year":"1987","journal-title":"J Clin Neurophysiol"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1002\/mus.880131006"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.36.9.1241"}],"container-title":["Muscle &amp; Nerve"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fmus.880161117","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/mus.880161117","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,25]],"date-time":"2023-10-25T11:04:28Z","timestamp":1698231868000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/mus.880161117"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1993,11]]},"references-count":12,"journal-issue":{"issue":"11","published-print":{"date-parts":[[1993,11]]}},"alternative-id":["10.1002\/mus.880161117"],"URL":"https:\/\/doi.org\/10.1002\/mus.880161117","archive":["Portico"],"relation":{},"ISSN":["0148-639X","1097-4598"],"issn-type":[{"value":"0148-639X","type":"print"},{"value":"1097-4598","type":"electronic"}],"subject":[],"published":{"date-parts":[[1993,11]]}}}
