Twenty\u2010two patients were studied with intractable focal epilepsy with tonic limb posturing as the most prominent semiology, who underwent resective surgery and obtained favorable postoperative seizure outcomes. These 22 patients were divided into an <jats:styled-content style=\"fixed-case\">SSMA<\/jats:styled-content> group (N = 12) and an extra\u2010<jats:styled-content style=\"fixed-case\">SSMA<\/jats:styled-content> group (N = 10), according to the location of resection. Resection area in the extra\u2010<jats:styled-content style=\"fixed-case\">SSMA<\/jats:styled-content> group was located in the dorsolateral frontal or prefrontal area in four patients, the frontal operculum (insula) in two, the parietal cortex in three, and the temporoparietal cortex in one patient. Video\u2010recorded seizures were carefully reviewed. Tonic posturing characteristics and the presence or absence of accompanying symptoms were compared between groups. Incidence of preservation of consciousness was significantly higher in the <jats:styled-content style=\"fixed-case\">SSMA<\/jats:styled-content> group (p &lt; 0.001). Patients in the <jats:styled-content style=\"fixed-case\">SSMA<\/jats:styled-content> group demonstrated a propensity for having unilateral or bilateral asymmetrical tonic limb posturing. In contrast, patients in the extra\u2010<jats:styled-content style=\"fixed-case\">SSMA<\/jats:styled-content> group had a statistically significantly higher incidence of bilateral symmetrical tonic limb posturing (p &lt; 0.05). These findings may be helpful in identifying seizure origin.<\/jats:p>","DOI":"10.1111\/epi.13283","type":"journal-article","created":{"date-parts":[[2015,12,13]],"date-time":"2015-12-13T05:27:14Z","timestamp":1449984434000},"source":"Crossref","is-referenced-by-count":10,"title":["Seizures with tonic posturing: Semiologic difference between supplementary sensorimotor area (<scp>SSMA<\/scp>) origin and extra\u2010<scp>SSMA<\/scp> origin"],"prefix":"10.1111","volume":"57","author":[{"given":"Bunpot","family":"Sitthinamsuwan","sequence":"first","affiliation":[{"name":"National Epilepsy Center Shizuoka Institute of Epilepsy and Neurological Disorders Shizuoka Japan"},{"name":"Division of Neurosurgery Department of Surgery Faculty of Medicine Siriraj Hospital Mahidol University Bangkok Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naotaka","family":"Usui","sequence":"additional","affiliation":[{"name":"National Epilepsy Center Shizuoka Institute of Epilepsy and Neurological Disorders Shizuoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takayasu","family":"Tottori","sequence":"additional","affiliation":[{"name":"National Epilepsy Center Shizuoka Institute of Epilepsy and Neurological Disorders Shizuoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kiyohito","family":"Terada","sequence":"additional","affiliation":[{"name":"National Epilepsy Center Shizuoka Institute of Epilepsy and Neurological Disorders Shizuoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akihiko","family":"Kondo","sequence":"additional","affiliation":[{"name":"National Epilepsy Center Shizuoka Institute of Epilepsy and Neurological Disorders Shizuoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazumi","family":"Matsuda","sequence":"additional","affiliation":[{"name":"National Epilepsy Center Shizuoka Institute of Epilepsy and Neurological Disorders Shizuoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Koichi","family":"Baba","sequence":"additional","affiliation":[{"name":"National Epilepsy Center Shizuoka Institute of Epilepsy and Neurological Disorders Shizuoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yushi","family":"Inoue","sequence":"additional","affiliation":[{"name":"National Epilepsy Center Shizuoka Institute of Epilepsy and Neurological Disorders Shizuoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2015,12,13]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/0013-4694(94)90068-X"},{"key":"e_1_2_7_3_1","first-page":"271","volume-title":"Advances in neurology","author":"Bleasel AF","year":"1996"},{"key":"e_1_2_7_4_1","first-page":"389","volume-title":"Epileptic Seizures: Pathophysiology and Clinical Semiology","author":"Bleasel A","year":"2000"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-510X(02)00199-5"},{"key":"e_1_2_7_6_1","first-page":"185","volume-title":"Frontal lobe seizures and epilepsy.
