The Authors studied postural changes in the lumbosacral segment of the spine due to severe obesity in 28 young adults of both sexes. In particular, the preliminary degree of pelvic rotation caused by overweight was evaluated by studying the lumbosacral angle (LSA) amplitude, changes in normal static equilibrium of the spine and lumbar hyperlordosis in relation to the lordotic angle (LA) amplitude. Body Build Index (BBI), the lumbosacral angle and the lordotic angle were compared to determine if any correlations existed among the three. Even though the patient number was limited, pathologic values for both the LSA and the LA were found in all 28 subjects. The Authors found no correlation between LSA and LA increase regarding BBI; on the contrary, a correlation was evident between LSA increase and LA. A decrease in the LSA and LA values took place after reduction in body weight, after therapeutic intervention. The Authors believe that a one year follow-up is necessary to evaluate any long term decrease in the values of the above mentioned angles.
作者对28名男女青年因严重肥胖导致的脊柱腰骶段姿势变化进行了研究。具体而言，通过研究腰骶角（LSA）幅度、脊柱正常静态平衡的变化以及与脊柱前凸角（LA）幅度相关的腰椎前凸，评估超重引起的骨盆旋转初始程度。比较身体形态指数（BBI）、腰骶角和脊柱前凸角，以确定三者之间是否存在任何相关性。尽管患者数量有限，但在所有28名受试者中均发现了LSA和LA的病理值。作者发现LSA和LA的增加与BBI之间无相关性；相反，LSA增加与LA之间存在明显相关性。经过治疗干预体重减轻后，LSA和LA值下降。作者认为有必要进行一年的随访，以评估上述角度值的任何长期下降情况。
