The purpose of this study was to examine the relationships between measurements of lumbar lordosis, pelvic tilt, and abdominal muscle performance during normal standing. In addition, the reliability of the measurements used in this study was examined. Measurements of lumbar lordosis, pelvic tilt, and abdominal muscle performance were taken of 31 healthy adults aged 20 to 33 years. Each measurement was taken twice, and the measurements were shown to be reliable. The Spearman's rho correlation of the abdominal muscle performance measurements with pelvic tilt was .18 and with lordosis was .06. The Pearson product-moment correlation of lordosis with pelvic tilt was .32. The results indicate that lumbar lordosis, pelvic tilt, and abdominal muscle function during normal standing are not related. This study demonstrates the need for a reexamination of clinical practices based on assumed relationships of abdominal muscle performance, pelvic tilt, and lordosis.
本研究的目的是探讨正常站立时腰椎前凸、骨盆倾斜度与腹部肌肉功能之间的关系。此外，还对本研究中所采用测量方法的可靠性进行了检验。对31名年龄在20至33岁之间的健康成年人进行了腰椎前凸、骨盆倾斜度及腹部肌肉功能的测量。每项测量均进行了两次，结果表明这些测量是可靠的。腹部肌肉功能测量值与骨盆倾斜度的Spearman等级相关系数为0.18，与腰椎前凸的相关系数为0.06。腰椎前凸与骨盆倾斜度的Pearson积差相关系数为0.32。结果表明，正常站立时的腰椎前凸、骨盆倾斜度和腹部肌肉功能之间并无关联。本研究表明，有必要重新审视基于腹部肌肉功能、骨盆倾斜度和腰椎前凸之间假定关系的临床实践。
