We describe a gait disorder which appears unique to XDP, involving phasic dystonic knee bending superimposed on parkinsonian shuffling, and may help clinically differentiate one of our parkinsonian\u2010predominant patients from more\u2010common forms of parkinsonism. The gait is distinct from other complex dystonic disorders with gait involvement.<\/jats:p><\/jats:sec>","DOI":"10.1002\/mdc3.12929","type":"journal-article","created":{"date-parts":[[2020,3,2]],"date-time":"2020-03-02T10:54:43Z","timestamp":1583146483000},"page":"448-452","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Phasic Knee Bending Dystonic and Parkinsonian Gait: A Characteristic Finding in <scp>X\u2010Linked<\/scp> Dystonia Parkinsonism"],"prefix":"10.1002","volume":"7","author":[{"given":"Christopher D.","family":"Stephen","sequence":"first","affiliation":[{"name":"Dystonia Clinic and Movement Disorders Unit Department of Neurology, Massachusetts General Hospital and Harvard Medical School  Boston MA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Criscely L.","family":"Go","sequence":"additional","affiliation":[{"name":"Department of Behavioral Medicine Jose Reyes Memorial Medical Center  Manila Philippines"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patrick","family":"Acuna","sequence":"additional","affiliation":[{"name":"Dystonia Clinic and Movement Disorders Unit Department of Neurology, Massachusetts General Hospital and Harvard Medical School  Boston MA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nutan","family":"Sharma","sequence":"additional","affiliation":[{"name":"Dystonia Clinic and Movement Disorders Unit Department of Neurology, Massachusetts General Hospital and Harvard Medical School  Boston MA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2020,3,26]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1353-8020(02)00042-1"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/mds.10271"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1712526114"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/mds.1263"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.3109\/00207454.2010.526728"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/ana.23832"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/mds.23866"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jns.2014.03.057"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/mds.23052"}],"container-title":["Movement Disorders Clinical Practice"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fmdc3.12929","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/mdc3.12929","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/mdc3.12929","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/movementdisorders.onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/mdc3.12929","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,20]],"date-time":"2025-10-20T13:34:45Z","timestamp":1760967285000},"score":1,"resource":{"primary":{"URL":"https:\/\/movementdisorders.onlinelibrary.wiley.com\/doi\/10.1002\/mdc3.12929"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,3,26]]},"references-count":9,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2020,5]]}},"alternative-id":["10.1002\/mdc3.12929"],"URL":"https:\/\/doi.org\/10.1002\/mdc3.12929","archive":["Portico"],"relation":{},"ISSN":["2330-1619","2330-1619"],"issn-type":[{"type":"print","value":"2330-1619"},{"type":"electronic","value":"2330-1619"}],"subject":[],"published":{"date-parts":[[2020,3,26]]},"assertion":[{"value":"2019-02-08","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2020-02-26","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2020-03-26","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
