Adult overhead athletes without a history of shoulder injury show scapular adaptations. There is a lack of detailed assessment of scapular kinematics in junior overhead athletes. This study aims to investigate three-dimensional scapular kinematics in junior overhead athletes. We recruited a total of 20 junior tennis players and 20 healthy children without participation in any overhead sports in this study. Bilateral scapular kinematic data were recorded using an electromagnetic tracking device for scapular plane glenohumeral elevation. The data were further analysed at 30°, 45°, 60°, 90° and 120° during glenohumeral elevation and lowering. Statistical comparisons of the data between groups (junior overhead athletes and non-overhead athletes) and sides (serve dominant and non-dominant shoulders of the overhead athletes) were analysed with the ANOVA. Comparisons showed that, in general, the scapula was more upwardly rotated and anteriorly tilted in overhead athletes when compared to non-overhead athletes, however there was no side-to-side differences when serve dominant and non-dominant shoulders compared in junior overhead athletes. The serve dominant arm of junior overhead athletes had alternations in scapular kinematics when compared with the non-overhead athletes. These findings provide clinical evaluation implications and the need for clinicians to assess for potential adaptations in junior overhead athletes.
没有肩部损伤史的成年过头运动运动员表现出肩胛骨适应性变化。青少年过头运动运动员的肩胛骨运动学缺乏详细评估。本研究旨在调查青少年过头运动运动员的三维肩胛骨运动学。在本研究中，我们共招募了20名青少年网球运动员和20名未参加任何过头运动的健康儿童。使用电磁跟踪设备记录双侧肩胛骨运动学数据，用于肩胛骨平面内肱骨头抬高动作。在肱骨头抬高和下降过程中的30°、45°、60°、90°和120°时对数据进行进一步分析。采用方差分析对组间（青少年过头运动运动员和非过头运动运动员）和两侧（过头运动运动员的发球侧肩和非发球侧肩）的数据进行统计学比较。比较结果显示，总体而言，与非过头运动运动员相比，过头运动运动员的肩胛骨向上旋转和前倾更为明显，然而，在青少年过头运动运动员中，发球侧肩和非发球侧肩相比没有差异。与非过头运动运动员相比，青少年过头运动运动员的发球侧手臂肩胛骨运动学存在变化。这些发现为临床评估提供了启示，也表明临床医生有必要评估青少年过头运动运动员的潜在适应性变化。
