. The aim of the study was to assess the change of sagittal spinal curvatures in children with generalized joint hypermobility (GJH) instructed with "straighten your back" command (SYB). . 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. . Children with GJH after SYB presented the following: in standing, increase in SS and decrease in TK, LK, and UK ( < 0.01), with LL not significantly changed; in sitting: decrease in global thoracic kyphosis (35.5° (SD 20.5) versus 21.0° (SD 15.5), < 0.001) below the standards proposed in the literature (30-40°) and flattening of its lower part ( < 0.001). The same changes were observed in the control group. . In children with generalized joint hypermobility, the "straighten your back" command leads to excessive reduction of the global thoracic kyphosis and flattening of its lower part. Therefore, the "straighten your back" command should not be used to achieve the optimal standing and sitting positions.
本研究旨在评估接受“挺直背部”指令（SYB）的全身关节过度活动症（GJH）儿童矢状面脊柱曲度的变化。本研究纳入了56例GJH儿童。对照组由193名儿童组成。使用桑德斯倾角仪在自然姿势（站立和坐姿）以及SYB指令后评估骶骨斜率（SS）、腰椎前凸（LL）、全胸段后凸（TK）、下胸段后凸（LK）和上胸段后凸（UK）。接受SYB指令后的GJH儿童表现如下：站立时，SS增加，TK、LK和UK减小（<0.01），LL无显著变化；坐姿时：全胸段后凸减小（35.5°（标准差20.5）对21.0°（标准差15.5），<0.001），低于文献提出的标准（30 - 40°），且其下部变平（<0.001）。对照组也观察到了相同的变化。在全身关节过度活动症儿童中，“挺直背部”指令会导致全胸段后凸过度减小及其下部变平。因此，“挺直背部”指令不应被用于实现最佳的站立和坐姿。
