The purpose of this study was to cross\u2010culturally adapt and validate the Simplified Chinese version of the Lower Extremity Functional Scale (SC\u2010LEFS).\n                    <jats:italic>Methods<\/jats:italic>\n                    . The original English version of the Lower Extremity Functional Scale was translated and cross\u2010culturally adapted into Simplified Chinese according to international guidelines. The SC\u2010LEFS and 36\u2010Item Short\u2010Form Health Survey were administered to 213 patients with lower extremity musculoskeletal disorders. Psychometric properties including internal consistency, test\u2010retest reliability, content validity, and construct validity were tested.\n                    <jats:italic>Results<\/jats:italic>\n                    . There were no floor or ceiling effects for the SC\u2010LEFS. The scale had high values for internal consistency (Cronbach\n                    <jats:italic>\u03b1<\/jats:italic>\n                    = 0.97) and test\u2010retest reliability (intraclass correlation coefficient = 0.97). Corrected item\u2010total correlations for every item ranged from 0.67 to 0.89. And the item\u2010level content validity index (I\u2010CVI) for each item ranged from 0.78 to 1.00. Principal component analysis revealed a one\u2010factor structure. Nine of ten prior hypotheses were confirmed, which further supports good construct validity within the SC\u2010LEFS.\n                    <jats:italic>Conclusion<\/jats:italic>\n                    . The SC\u2010LEFS has high internal consistency, good test\u2010retest reliability and content validity, convergent construct validity, and a one\u2010factor structure. Thus, it could be regarded as a reliable and valid tool to assess activity limitations in Chinese patients with lower extremity musculoskeletal disorders.\n                  <\/jats:p>","DOI":"10.1155\/2020\/1421429","type":"journal-article","created":{"date-parts":[[2020,3,11]],"date-time":"2020-03-11T19:30:39Z","timestamp":1583955039000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Cross\u2010Cultural Adaptation and Validation of the Simplified Chinese Version of the Lower Extremity Functional Scale"],"prefix":"10.1155","volume":"2020","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7408-9464","authenticated-orcid":false,"given":"Chuanxin","family":"Zhang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5606-4527","authenticated-orcid":false,"given":"Yaqun","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuai","family":"Yuan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4914-588X","authenticated-orcid":false,"given":"Tianbo","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9996-8086","authenticated-orcid":false,"given":"Yuan","family":"Gao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6193-4278","authenticated-orcid":false,"given":"Chao","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8304-0208","authenticated-orcid":false,"given":"Zheru","family":"Ding","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,3,11]]},"reference":[{"key":"e_1_2_10_1_2","doi-asserted-by":"publisher","DOI":"10.2486\/indhealth.2016-0191"},{"key":"e_1_2_10_2_2","doi-asserted-by":"publisher","DOI":"10.1136\/annrheumdis-2013-204344"},{"key":"e_1_2_10_3_2","doi-asserted-by":"publisher","DOI":"10.7150\/ijms.4503"},{"key":"e_1_2_10_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/art.20089"},{"key":"e_1_2_10_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00296-016-3539-7"},{"key":"e_1_2_10_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.joca.2012.08.018"},{"key":"e_1_2_10_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jclinepi.2008.11.011"},{"key":"e_1_2_10_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.artd.2018.09.003"},{"key":"e_1_2_10_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jclinepi.2004.03.008"},{"key":"e_1_2_10_10_2","doi-asserted-by":"publisher","DOI":"10.1093\/ptj\/79.4.371"},{"key":"e_1_2_10_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jclinepi.2009.08.001"},{"key":"e_1_2_10_12_2","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2474-13-117"},{"key":"e_1_2_10_13_2","doi-asserted-by":"publisher","DOI":"10.3109\/09638288.2014.890673"},{"key":"e_1_2_10_14_2","first-page":"530","article-title":"Association between abductor muscle strength and functional outcomes in hip-fractured patients: a cross-sectional study","volume":"18","author":"Stasi S.","year":"2018","journal-title":"Journal of Musculoskeletal & Neuronal Interactions"},{"key":"e_1_2_10_15_2","doi-asserted-by":"publisher","DOI":"10.2519\/jospt.2012.4101"},{"key":"e_1_2_10_16_2","doi-asserted-by":"publisher","DOI":"10.3109\/09638288.2015.1066452"},{"key":"e_1_2_10_17_2","doi-asserted-by":"publisher","DOI":"10.3109\/09638288.2013.775361"},{"key":"e_1_2_10_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jclinepi.2006.03.012"},{"key":"e_1_2_10_19_2","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-200012150-00014"},{"key":"e_1_2_10_20_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jclinepi.2010.02.006"},{"key":"e_1_2_10_21_2","doi-asserted-by":"publisher","DOI":"10.1007\/bf01593882"},{"key":"e_1_2_10_22_2","doi-asserted-by":"publisher","DOI":"10.1093\/oso\/9780198528470.001.0001"},{"key":"e_1_2_10_23_2","doi-asserted-by":"publisher","DOI":"10.1207\/S15327752JPA8001_18"},{"key":"e_1_2_10_24_2","doi-asserted-by":"publisher","DOI":"10.1519\/15184.1"},{"key":"e_1_2_10_25_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11136-018-1798-3"},{"key":"e_1_2_10_26_2","doi-asserted-by":"publisher","DOI":"10.1097\/00006199-198611000-00017"},{"key":"e_1_2_10_27_2","doi-asserted-by":"publisher","DOI":"10.1002\/nur.20199"},{"key":"e_1_2_10_28_2","volume-title":"Scale Development: Theory and Applications","author":"DeVellis R.
