For 1, 4, and 5 years, they reported additional involuntary trunk and limbs jerks preceding falling asleep and occasionally during intrasleep wakefulness. Videopolysomnography revealed jerks during relaxed wakefulness arising in axial muscles with a caudal and rostral propagation at a slow conduction velocity, characteristic of propriospinal myoclonus (PSM). Jerk\u2010related EEG\u2013EMG back\u2010averaging did not disclose any preceding cortical potential. During relaxed wakefulness preceding falling asleep and during intrasleep wakefulness, PSM coexisted with motor restlessness and sensory discomfort in the limbs. PSM disappeared when spindles and K\u2010complexes appeared on the EEG. At this time, typical PLMS appeared every 20 to 40 seconds, especially during light sleep stages. PLMS EMG activity was limited to leg, especially tibialis anterior muscles, and did not show propriospinal propagation. In one patient, alternating leg muscle activation was also present. Jerks with a PSM pattern represent another motor phenomenon associated with RLS and different from the more usual PLMS. \u00a9 2005 Movement Disorder Society<\/jats:p>","DOI":"10.1002\/mds.20599","type":"journal-article","created":{"date-parts":[[2005,7,8]],"date-time":"2005-07-08T17:12:34Z","timestamp":1120842754000},"page":"1323-1329","source":"Crossref","is-referenced-by-count":37,"title":["Propriospinal myoclonus: A motor phenomenon found in restless legs syndrome different from periodic limb movements during sleep"],"prefix":"10.1002","volume":"20","author":[{"given":"Roberto","family":"Vetrugno","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Federica","family":"Provini","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giuseppe","family":"Plazzi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pietro","family":"Cortelli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pasquale","family":"Montagna","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2005,7,8]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870100517"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1389-9457(03)00010-8"},{"key":"e_1_2_6_4_2","first-page":"265","volume-title":"Sleeping and waking disorders: indications and techniques","author":"Coleman RM","year":"1982"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870120111"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1389-9457(01)00123-X"},{"key":"e_1_2_6_7_2","first-page":"197","article-title":"Axial myoclonus of propriospinal origin","volume":"114","author":"Brown P","year":"1991","journal-title":"Brain"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870120112"},{"key":"e_1_2_6_9_2","first-page":"835","article-title":"Propriospinal myoclonus at the sleep\u2010wake transition: a new type of parasomnia","volume":"24","author":"Vetrugno R","year":"2001","journal-title":"Sleep"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1093\/sleep\/14.6.540"},{"key":"e_1_2_6_11_2","volume-title":"A manual of standardised terminology, techniques and scoring system for sleep stages in human subjects","author":"Rechtschaffen A","year":"1968"},{"key":"e_1_2_6_12_2","first-page":"1197","volume-title":"Principles and practice of sleep medicine","author":"Carskadon MA","year":"2000"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.10397"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-4598(199602)19:2<155::AID-MUS5>3.0.CO;2-D"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.57.2.300"},{"key":"e_1_2_6_16_2","first-page":"317","article-title":"Activity pattern in periodic limb movement disorder","volume":"75","author":"De Weerd AW","year":"2004","journal-title":"J Neurol Neurosurg Psychiatry"},{"key":"e_1_2_6_17_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.53.6.1201"},{"key":"e_1_2_6_18_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.54.8.1609"},{"key":"e_1_2_6_19_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.52.5.1060"},{"key":"e_1_2_6_20_2","first-page":"619","article-title":"La sindrome delle gambe senza riposo (restless legs)","volume":"44","author":"Coccagna G","year":"1966","journal-title":"Omnia Med Ther"},{"key":"e_1_2_6_21_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0404.1988.tb05929.x"},{"key":"e_1_2_6_22_2","doi-asserted-by":"publisher","DOI":"10.1002\/mds.10304"}],"container-title":["Movement Disorders"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fmds.20599","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/movementdisorders.onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/mds.20599","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,20]],"date-time":"2025-10-20T14:30:40Z","timestamp":1760970640000},"score":1,"resource":{"primary":{"URL":"https:\/\/movementdisorders.onlinelibrary.wiley.com\/doi\/10.1002\/mds.20599"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2005,7,8]]},"references-count":21,"journal-issue":{"issue":"10","published-print":{"date-parts":[[2005,10]]}},"alternative-id":["10.1002\/mds.20599"],"URL":"https:\/\/doi.org\/10.1002\/mds.20599","archive":["Portico"],"relation":{},"ISSN":["0885-3185","1531-8257"],"issn-type":[{"value":"0885-3185","type":"print"},{"value":"1531-8257","type":"electronic"}],"subject":[],"published":{"date-parts":[[2005,7,8]]}}}
