The data were compared with those collected from a group of patients affected by Parkinson's disease (PD) and normal age\u2010matched subjects. N30 amplitude was significantly decreased in both groups of patients with respect to the controls. The decrease was larger in patients with ST. The N20 wave remained stable. The latencies of both waves were unchanged. When the stimulus rate was increased, the N30 amplitude decreased significantly, with a similar trend observed in both patients and controls. The isolated abnormalities of the N30 wave in both ST and PD support the hypothesis of a common physiopathogenetic mechanism that involves the basal ganglia or their connections with the supplementary motor area.<\/jats:p>","DOI":"10.1002\/mds.870090408","type":"journal-article","created":{"date-parts":[[2004,12,31]],"date-time":"2004-12-31T11:36:23Z","timestamp":1104492983000},"page":"426-430","source":"Crossref","is-referenced-by-count":38,"title":["Abnormalities of somatosensory evoked potentials in spasmodic torticollis"],"prefix":"10.1002","volume":"9","author":[{"given":"L.","family":"Mazzini","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Zaccala","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"Balzarini","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2004,10,12]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/0168-5597(89)90058-0"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/0168-5597(90)90055-I"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/0168-5597(91)90108-A"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/116.1.87"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/0168-5597(92)90005-V"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/106.2.271"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/113.5.1501"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/0168-5597(87)90065-7"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.37.4.616"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(71)92226-4"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/0168-5597(90)90021-5"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/0022-510X(91)90115-N"},{"key":"e_1_2_1_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/0013-4694(86)90091-X"},{"key":"e_1_2_1_15_2","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/110.2.451"},{"key":"e_1_2_1_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/0168-5597(91)90134-J"},{"key":"e_1_2_1_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/0006-8993(89)91068-8"},{"key":"e_1_2_1_18_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870060109"},{"key":"e_1_2_1_19_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.40.5.824"},{"key":"e_1_2_1_20_2","first-page":"313","volume-title":"Movement disorders","author":"Rothwell JC","year":"1987"},{"key":"e_1_2_1_21_2","doi-asserted-by":"publisher","DOI":"10.1002\/ana.410230112"},{"key":"e_1_2_1_22_2","doi-asserted-by":"publisher","DOI":"10.1016\/0168-5597(89)90002-6"},{"key":"e_1_2_1_23_2","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-444-81352-7.50018-2"},{"key":"e_1_2_1_24_2","doi-asserted-by":"publisher","DOI":"10.1016\/0168-5597(92)90069-N"},{"key":"e_1_2_1_25_2","doi-asserted-by":"publisher","DOI":"10.1016\/0022-510X(93)90315-P"},{"key":"e_1_2_1_26_2","doi-asserted-by":"publisher","DOI":"10.1016\/0165-0173(85)90010-4"},{"key":"e_1_2_1_27_2","doi-asserted-by":"publisher","DOI":"10.1002\/ana.410320309"},{"key":"e_1_2_1_28_2","doi-asserted-by":"publisher","DOI":"10.1016\/0166-2236(89)90074-X"},{"key":"e_1_2_1_29_2","first-page":"417","article-title":"La r\u00e8gion de l'aire motrice suppl\u00e8mentaire est impliqu\u00e8e dans la coordination entre posture et mouvement chezl'homme","volume":"308","author":"Massion J","year":"1989","journal-title":"C R Acad Sci [III]"}],"container-title":["Movement Disorders"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fmds.870090408","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/movementdisorders.onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/mds.870090408","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,20]],"date-time":"2025-10-20T09:49:42Z","timestamp":1760953782000},"score":1,"resource":{"primary":{"URL":"https:\/\/movementdisorders.onlinelibrary.wiley.com\/doi\/10.1002\/mds.870090408"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1994,1]]},"references-count":28,"journal-issue":{"issue":"4","published-print":{"date-parts":[[1994,1]]}},"alternative-id":["10.1002\/mds.870090408"],"URL":"https:\/\/doi.org\/10.1002\/mds.870090408","archive":["Portico"],"relation":{},"ISSN":["0885-3185","1531-8257"],"issn-type":[{"type":"print","value":"0885-3185"},{"type":"electronic","value":"1531-8257"}],"subject":[],"published":{"date-parts":[[1994,1]]}}}
