提出了一种全局坐标系（GCS）方法，根据感兴趣的关节中心和目标解剖标志（AL）之间的至少三个距离来估计髋关节和腰骶关节中心（HJC和LSJC）。根据通常的骨盆和股骨缩放尺寸，分析从 HJC 和 LSJC 到相关骨盆和股骨 AL 的距离。对来自同一成人标本样本的四十六个骨盆和相关的股骨进行了检查。得到相应的回归方程。这些方程可用于在 AL 数量非常有限的情况下估计 HJC 和 LSJC：例如，在汽车行业执行的坐姿分析期间。与现有的 AL 的 HJC 和 LSJC 方法相比，该方法显示出更好的结果，平均误差小于 11 mm。 (C) 2014 Elsevier Ltd. 保留所有权利。
A global coordinate system (GCS) method is proposed to estimate hip and lumbosacral joint centers (HJC and LSJC) from at least three distances between joint center of interest and target anatomic landmarks (ALs). The distances from HJC and LSJC to relevant pelvis and femur ALs were analyzed with respect to usual pelvis and femur scaling dimensions. Forty six pelves and related pairs of femurs from a same sample of adult specimens were examined. The corresponding regression equations were obtained. These equations can be used to estimate HJC and LSJC in conditions where a very limited number of ALs are available: for example, during seated posture analysis as performed in the automotive industry. Compared to currently existing HJC and LSJC methods from ALs, the proposed method showed better results with an average error less than 11 mm. (C) 2014 Elsevier Ltd. All rights reserved.
