背景肩胛骨的适当运动对于肱骨上举过程中关节盂的动态定位非常重要。许多研究已经描述了成人肱骨抬高过程中典型的肩胛骨运动学。然而，儿童和成人在肩胛胸肌肉组织和肩胛骨方面可能存在差异。据我们所知，没有研究已经进行检查肩胛骨运动学的儿童无论是典型的或非典型的发展。因此，在儿童中，年龄和发育对肩胛骨运动的影响目前尚不清楚。本研究的目的是描述和比较典型发育的儿童和健康成人在肱骨抬高过程中肩胛骨的运动学模式。15名成人（7名女性，25-37岁）和14名儿童（8名女性，4-9岁）参加了本研究。使用磁跟踪装置收集运动学数据。受试者被要求在肩胛平面（额状面前40度）抬高手臂，顺序进行三次试验。两个年龄组的因变量存在显著差异。在肩胛平面旋转25 °至125 °期间，儿童表现出比成人（29.1 ° SD 10.1 °）更大的向上旋转（43.9 ° SD 6.39 °）。肩胛平面的平均盂肱/肩胛胸比成人为2.4：1，儿童为1.3：1。这项研究表明，有儿童和成人肩胛骨运动模式的显着差异。儿童肩胸关节的贡献更大，特别是向上旋转向肱骨抬高。从临床的角度来看，这些结果可以用来帮助确定合并的稳定和动员肩胛胸关节在演习中的儿童在肩部损伤，以改善肩关节功能。(c)2005爱思唯尔有限公司保留所有权利。
Background. Appropriate motion of the scapula is important for dynamic positioning of the glenoid during humeral elevation. A number of studies have described the typical scapular kinematics during humeral elevation in adults. However, children and adults may have differences in scapulothoracic musculature and scapular osteology. To our knowledge, no study has been performed examining scapular kinematics in children with either typical or atypical development. Consequently in children the influence of age and development on scapular motion is currently unknown. The aim of this study was to describe and compare the kinematic patterns of the scapula during humeral elevation in children with typical development and healthy adults.Methods. Fifteen adults, 7 females, 25-37 years of age, and 14 children, 8 females, 4-9 years of age, participated in this study. Kinematic data were collected using a magnetic tracking device. Subjects were asked to elevate their arm in the scapular plane (40 degrees anterior to the frontal plane) in a sequence of three trials.Findings. Significant differences were seen between the two age groups in the dependent variables. During scapular plane rotation from 25 degrees to 125 degrees, children showed greater upward rotation (43.9 degrees SD 6.39 degrees) than adults (29.1 degrees SD 10.1 degrees). The mean glenohumeral to scapulothoracic ratio in the scapular plane was 2.4:1 for adults, 1.3:1 for children.Interpretation. This study demonstrates that there are significant differences in scapular kinematic patterns between children and adults. Children have a greater contribution from the scapulothoracic joint, specifically upward rotation toward humeral elevation. From a clinical perspective, these results can be used to help determine the incorporation of stabilization and mobilization of the scapulothoracic joint during exercises for a child with impairment at the shoulder for improving shoulder function.
