We investigated the relevance of this phenomenon in 375 consecutive subjects examined polysomnographically in a sleep disorders center. Rhythmic feet movements while falling asleep (RFM) were found in 28 subjects (7.5%). RFM occurred mostly as single, short series with a duration of between 10 and 15 seconds. They had a high night\u2010to\u2010night variability and were detected as rhythmic, oscillating movements of the whole foot or toes. Surface electromyographic (EMG) recordings displayed series of repetitive phasic bursts with a periodicity mostly between 1 and 2 per second. Single EMG burst duration varied between 300 and 700 msec. RFM at highest intensity occurred during presleep wakefulness, and usually persisted in sleep stages 1 and 2. RFM did not have a major sleep\u2010disturbing effect in any of the affected subjects. Due to its high prevalence and the lack of a major sleep\u2010disturbing effect, short series of RFM could be considered a quasiphysiological phenomenon. However, in more severe forms of RFM with evidence of a sleep\u2010disturbing effect, RFM should be considered abnormal. \u00a9 2001 Movement Disorder Society.<\/jats:p>","DOI":"10.1002\/mds.1216","type":"journal-article","created":{"date-parts":[[2002,8,25]],"date-time":"2002-08-25T12:25:38Z","timestamp":1030278338000},"page":"1164-1170","source":"Crossref","is-referenced-by-count":56,"title":["Rhythmic feet movements while falling asleep"],"prefix":"10.1002","volume":"16","author":[{"given":"Adam","family":"Wichniak","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ferenc","family":"Tracik","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter","family":"Geisler","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Georg","family":"Ebersbach","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sean P.","family":"Morrissey","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J\u00fcrgen","family":"Zulley","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2001,11,30]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/82.1.92"},{"key":"e_1_2_6_3_2","first-page":"481","article-title":"Su di un fenomeno motorio constante del sonno normale: le myoclonie ipniche fisiologishe","volume":"39","author":"De Lisi L","year":"1932","journal-title":"Riv Pat nerv ment"},{"key":"e_1_2_6_4_2","first-page":"240","volume-title":"Sleep '86.
