The purpose of this paper is to analyze the relationship between the alignment of the body of sternum and sacrum and the changes in the thoracic and lumbar spine curvatures in children. The study involved 113 subjects aged 9\u201313 years. A planned simultaneous measurement of the angle parameters of the alignment of the body of sternum and sacrum relative to the body\u2019s sagittal axis and the angle parameters of the thoracic and lumbar spine curvatures was performed during a single examination session. The proposed markers of alignment in the corrected sitting body posture are characterized by homogeneous results. A high measurement repeatability was observed when determining the corrected body posture in the study setting. It was noted that changes in the alignment of the body of sternum and sacrum resulted in changes in the thoracic kyphosis and lumbar lordosis angle values, which may be an important component of clinical observations of sitting body posture in children. Implementing the body of sternum alignment angle of about 64\u00b0 relative to the body\u2019s sagittal axis in clinical practice as one of the objectives of postural education may be the target solution for sitting body posture correction in children.<\/jats:p>","DOI":"10.3390\/ijerph192316287","type":"journal-article","created":{"date-parts":[[2022,12,5]],"date-time":"2022-12-05T08:10:57Z","timestamp":1670227857000},"page":"16287","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Alignment of the Sternum and Sacrum as a Marker of Sitting Body Posture in Children"],"prefix":"10.3390","volume":"19","author":[{"given":"Wojciech Piotr","family":"Kiebzak","sequence":"first","affiliation":[{"name":"Institute of Health Sciences, Collegium Medicum, The Jan Kochanowski University in Kielce, 25-369 Kielce, Poland"},{"name":"\u015awi\u0119tokrzyskie Centre for Paediatrics, Provincial Integrated Hospital in Kielce, 25-736 Kielce, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2564-8607","authenticated-orcid":false,"given":"Arkadiusz \u0141ukasz","family":"\u017burawski","sequence":"additional","affiliation":[{"name":"Institute of Health Sciences, Collegium Medicum, The Jan Kochanowski University in Kielce, 25-369 Kielce, Poland"},{"name":"\u015awi\u0119tokrzyskie Centre for Paediatrics, Provincial Integrated Hospital in Kielce, 25-736 Kielce, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Micha\u0142","family":"Koszto\u0142owicz","sequence":"additional","affiliation":[{"name":"Kieleckie Towarzystwo Naukowe, 25-303 Kielce, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"229","DOI":"10.4236\/aa.2013.34032","article-title":"Human Postural Adaptation to Erly and Atypical Gravitational Environment Effects of Sport Training on Stabilometric Parameters","volume":"3","author":"Pizzigalli","year":"2013","journal-title":"Adv.
