Although CP is a non-progressive condition, crouch gait can result in knee extensor disruption (KED) causing deterioration or cessation of ambulation. Diagnosis of KED in crouch gait is often overlooked. We report a seminal case of a 28-year-old active woman with diplegic CP with severe crouch gait who was referred for gait analysis due to subjective decreased walking speed and endurance. Gait analysis showed kinematic features typical of KED and radiology confirmed the diagnosis.<\/jats:p>","DOI":"10.1136\/bcr-2013-010337","type":"journal-article","created":{"date-parts":[[2013,6,28]],"date-time":"2013-06-28T12:19:49Z","timestamp":1372421989000},"page":"bcr2013010337","source":"Crossref","is-referenced-by-count":1,"title":["Bilateral knee extensor disruption in severe crouch gait"],"prefix":"10.1136","volume":"2013","author":[{"given":"Yahya","family":"Elhassan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Damien","family":"Kiernan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tim","family":"Lynch","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tim O","family":"Brien","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2013,6,27]]},"reference":[{"key":"2025042708260438000_2013.jun27_1.bcr2013010337.1","first-page":"139","article-title":"Common gait abnormalities of the knee in cerebral palsy","volume":"2013","author":"Sutherland","year":"1993","journal-title":"Clin Ortho"},{"key":"2025042708260438000_2013.jun27_1.bcr2013010337.2","unstructured":"Gage J Schwartz M Koop S .
