This retrospective cohort study was performed in 33 female professional CB dancers. Data related to anthropometric parameters, CB dance experience, sciatica or LBP history, and sagittal spine curvatures were collected. A binary logistic regression and receiver-operating characteristic analysis were performed. The main spine misalignments observed in the SIM of CB dancers were thoracic functional hyperkyphosis, hypomobile kyphosis, and hypokyphosis, and those for the lumbar curvature were hyperlordotic attitude and functional hyperkyphosis. The lumbar curvature in slump sitting and trunk forward bending positions, together with the stature, were significant predictor factors of sciatica history, while the years of dance experience was a significant predictor factor of LBP history. The cut off values analysis revealed that dancers with a stature of 161 cm or less, and those with 14 years of experience or more, have a greater probability of experiencing sciatica or LBP history, respectively.<\/jats:p>","DOI":"10.3390\/ijerph18095039","type":"journal-article","created":{"date-parts":[[2021,5,10]],"date-time":"2021-05-10T10:49:51Z","timestamp":1620643791000},"page":"5039","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Sagittal Integral Morphotype of Female Classical Ballet Dancers and Predictors of Sciatica and Low Back Pain"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5903-0843","authenticated-orcid":false,"given":"Antonio","family":"Cejudo","sequence":"first","affiliation":[{"name":"Department of Physical Activity and Sport, Faculty of Sport Sciences, Regional Campus of International Excellence \u201cCampus Mare Nostrum\u201d, University of Murcia, C.P., 30100 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebasti\u00e1n","family":"G\u00f3mez-Lozano","sequence":"additional","affiliation":[{"name":"Department of Sport and Physical Activity, Faculty of Sport, Jer\u00f3nimos Campus, Catholic University of Murcia UCAM, C.P., 30107 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1379-5151","authenticated-orcid":false,"given":"Pilar","family":"Sainz de Baranda","sequence":"additional","affiliation":[{"name":"Department of Physical Activity and Sport, Faculty of Sport Sciences, Regional Campus of International Excellence \u201cCampus Mare Nostrum\u201d, University of Murcia, C.P., 30100 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1222-6133","authenticated-orcid":false,"given":"Alfonso","family":"Vargas-Mac\u00edas","sequence":"additional","affiliation":[{"name":"Telethusa Centre for Flamenco Research, 11004 C\u00e1diz, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fernando","family":"Santonja-Medina","sequence":"additional","affiliation":[{"name":"Department of Medicine and Orthopaedic Surgery, Faculty of Medicine, Regional Campus of International Excellence \u201cCampus Mare Nostrum\u201d, University of Murcia, C.P., 30100 Murcia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"126","DOI":"10.2519\/jospt.2008.2390","article-title":"Injury Patterns in Elite Preprofessional Ballet Dancers and the Utility of Screening Programs to Identify Risk Characteristics","volume":"126","author":"Gamboa","year":"2008","journal-title":"J.
