The aim of the study was to assess the change of sagittal spinal curvatures in children with generalized joint hypermobility (GJH) instructed with \u201cstraighten your back\u201d command (SYB).<jats:italic>Methods<\/jats:italic>. The study included 56 children with GJH. The control group consisted of 193 children. Sacral slope (SS), lumbar lordosis (LL), global thoracic kyphosis (TK), lower thoracic kyphosis (LK), and upper thoracic kyphosis (UK) were assessed with Saunders inclinometer both in spontaneous positions (standing and sitting) and after the SYB.<jats:italic>Results<\/jats:italic>. Children with GJH after SYB presented the following: in standing, increase in SS and decrease in TK, LK, and UK (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mi>P<\/mml:mi><mml:mo>&lt;<\/mml:mo><mml:mn fontstyle=\"italic\">0.01<\/mml:mn><\/mml:math>), with LL not significantly changed; in sitting: decrease in global thoracic kyphosis (35.5\u00b0 (SD 20.5) versus 21.0\u00b0 (SD 15.5),<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\"><mml:mi>P<\/mml:mi><mml:mo>&lt;<\/mml:mo><mml:mn fontstyle=\"italic\">0.001<\/mml:mn><\/mml:math>) below the standards proposed in the literature (30\u201340\u00b0) and flattening of its lower part (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M3\"><mml:mi>P<\/mml:mi><mml:mo>&lt;<\/mml:mo><mml:mn fontstyle=\"italic\">0.001<\/mml:mn><\/mml:math>). The same changes were observed in the control group.<jats:italic>Conclusions<\/jats:italic>. In children with generalized joint hypermobility, the \u201cstraighten your back\u201d command leads to excessive reduction of the global thoracic kyphosis and flattening of its lower part. Therefore, the \u201cstraighten your back\u201d command should not be used to achieve the optimal standing and sitting positions.<\/jats:p>","DOI":"10.1155\/2017\/9724021","type":"journal-article","created":{"date-parts":[[2017,1,1]],"date-time":"2017-01-01T21:00:49Z","timestamp":1483304449000},"page":"1-7","source":"Crossref","is-referenced-by-count":12,"title":["The
