Many authors have suggested that the myoclonus in CBD is a subtype of cortical myoclonus, despite the fact that back\u2010averaging fails to detect a cortical correlate to spontaneous or action induced jerks and giant sensory evoked potentials are seldom found. Electroencephalographic\u2013electromyographic (EEG\u2013EMG) and EMG\u2013EMG frequency analysis may be more sensitive to cortical drives when EMG bursts occur at a high frequency and at low amplitudes as in CBD. We evaluated EEG\u2013EMG and EMG\u2013EMG coherence and phase in 5 patients with clinically probable CBD and unilateral, action\u2010induced and stimulus\u2010sensitive myoclonus. We found negligible corticomuscular coherence despite a dramatically exaggerated EMG\u2013EMG coherence. We conclude that an inflated EMG\u2013EMG coherence is found in some patients with CBD and that this is unlikely to be due to an exaggerated cortical drive. \u00a9 2003 Movement Disorder Society<\/jats:p>","DOI":"10.1002\/mds.10535","type":"journal-article","created":{"date-parts":[[2003,11,20]],"date-time":"2003-11-20T13:19:27Z","timestamp":1069334367000},"page":"1345-1350","source":"Crossref","is-referenced-by-count":31,"title":["Coherence analysis in the myoclonus of corticobasal degeneration"],"prefix":"10.1002","volume":"18","author":[{"given":"Pascal","family":"Grosse","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"K\u00fchn","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carla","family":"Cordivari","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Brown","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2003,8,21]]},"reference":[{"key":"e_1_2_5_2_2","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.55.7.957"},{"key":"e_1_2_5_3_2","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/117.5.1197"},{"key":"e_1_2_5_4_2","first-page":"711","article-title":"A case of clinically diagnosed corticobasal degeneration with unilateral cortical refle myoconus showing so\u2010called giant SEP","volume":"39","author":"Tanosaki M","year":"1999","journal-title":"Rinsho Shinkeigaku"},{"key":"e_1_2_5_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/ana.410430507"},{"key":"e_1_2_5_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870100203"},{"key":"e_1_2_5_7_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870130126"},{"key":"e_1_2_5_8_2","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/124.12.2459"},{"key":"e_1_2_5_9_2","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/122.3.461"},{"key":"e_1_2_5_10_2","first-page":"29","volume-title":"Corticobasal degeneration","author":"Riley DE","year":"2000"},{"key":"e_1_2_5_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0079-6107(96)00009-0"},{"key":"e_1_2_5_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0165-0270(98)00061-2"},{"key":"e_1_2_5_13_2","doi-asserted-by":"publisher","DOI":"10.1007\/s002210050764"},{"key":"e_1_2_5_14_2","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/awg043"},{"key":"e_1_2_5_15_2","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.1993.sp019851"},{"key":"e_1_2_5_16_2","doi-asserted-by":"publisher","DOI":"10.1006\/exnr.2000.7392"},{"key":"e_1_2_5_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0928-4680(00)00060-2"},{"key":"e_1_2_5_18_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870120419"}],"container-title":["Movement Disorders"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fmds.10535","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/movementdisorders.onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/mds.10535","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,20]],"date-time":"2025-10-20T10:36:12Z","timestamp":1760956572000},"score":1,"resource":{"primary":{"URL":"https:\/\/movementdisorders.onlinelibrary.wiley.com\/doi\/10.1002\/mds.10535"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2003,8,21]]},"references-count":17,"journal-issue":{"issue":"11","published-print":{"date-parts":[[2003,11]]}},"alternative-id":["10.1002\/mds.10535"],"URL":"https:\/\/doi.org\/10.1002\/mds.10535","archive":["Portico"],"relation":{},"ISSN":["0885-3185","1531-8257"],"issn-type":[{"value":"0885-3185","type":"print"},{"value":"1531-8257","type":"electronic"}],"subject":[],"published":{"date-parts":[[2003,8,21]]}}}
