Body representation can be divided into a conscious component, body image, and an unconscious action\u2010related one, body schema. As behavioral studies already explored the impact of a distorted body image in AN, we aimed to explore whether distortion also extends into unconscious body schema. This study is the first with an unbiased measurement of the body schema in a homogeneous sample of AN patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>Twenty\u2010three patients diagnosed with AN and 23 healthy controls (HC) walked through a door like aperture varying in width. Door width was based on participants shoulder width and ranged from an aperture\u2010to\u2010shoulder\u2010ratio of (A\/S) 0.9 to 1.45. Shoulder rotation was measured as indication of perceived body width. To measure the unconscious body schema, we used a cover story pretending to investigate the influence of change of position on retention memory.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We found a significantly higher critical A\/S for AN than HC, which indicates that AN patients rotate their shoulders for relatively larger door widths than HC, thus unconsciously estimating their body size to be larger than in reality. Additionally, we found a correlation between negative body attribution and overestimation of bodily dimensions.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>As stated by the \u201callocentric\u2010lock\u201d\u2010hypothesis, AN patients might be locked to a stored representation of their body that cannot be updated and remains at pre\u2010AN conditions. We suggest future AN\u2010therapy to counter body schema alterations by combining cognitive behavioral therapy and virtual reality therapy.<\/jats:p><\/jats:sec>","DOI":"10.1002\/eat.23451","type":"journal-article","created":{"date-parts":[[2020,12,21]],"date-time":"2020-12-21T06:57:18Z","timestamp":1608533838000},"page":"578-586","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":41,"title":["How the unconscious mind controls body movements: Body schema distortion in anorexia nervosa"],"prefix":"10.1002","volume":"54","author":[{"given":"Nina","family":"Beckmann","sequence":"first","affiliation":[{"name":"Department of Psychosomatic Medicine and Psychotherapy LWL University Hospital, Ruhr University Bochum  Bochum Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patricia","family":"Baumann","sequence":"additional","affiliation":[{"name":"Department of Psychosomatic Medicine and Psychotherapy LWL University Hospital, Ruhr University Bochum  Bochum Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephan","family":"Herpertz","sequence":"additional","affiliation":[{"name":"Department of Psychosomatic Medicine and Psychotherapy LWL University Hospital, Ruhr University Bochum  Bochum Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u00f6rg","family":"Trojan","sequence":"additional","affiliation":[{"name":"Department of Psychosomatic Medicine and Psychotherapy LWL University Hospital, Ruhr University Bochum  Bochum Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3257-7299","authenticated-orcid":false,"given":"Martin","family":"Diers","sequence":"additional","affiliation":[{"name":"Department of Psychosomatic Medicine and Psychotherapy LWL University Hospital, Ruhr University Bochum  Bochum Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,12,20]]},"reference":[{"issue":"3","key":"e_1_2_9_2_1","first-page":"99","article-title":"\u00dcberpr\u00fcfung und Normierung des \u201cFragebogen zum K\u00f6rperbild\u201d (FKB\u201020) von Clement und L\u00f6we (1996) an einer repr\u00e4sentativen deutschen Bev\u00f6lkerungsstichprobe","volume":"15","author":"Albani C.","year":"2006","journal-title":"Zeitschrift F\u00fcr Medizinische Psychologie"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1001\/archgenpsychiatry.2011.74"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neubiorev.2017.03.017"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1001\/archpsyc.1961.01710120031004"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/00006842-196203000-00009"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0924-9338(13)76475-7"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0033291703001168"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.psychres.2012.04.037"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00221-011-2974-7"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1098-108X(199709)22:2<107::AID-EAT1>3.0.CO;2-J"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/hbm.22541"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-90817-5_1"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuropsychologia.2009.10.008"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.concog.2010.09.004"},{"issue":"2","key":"e_1_2_9_16_1","article-title":"La realidad virtual, una nueva herramienta terap\u00e9utica.
