BACKGROUND
Previous studies have proposed various ways to assess scapular dyskinesis. In clinic, assessment tools designed to measure the posterior displacement of the inferior angle of the scapula with reference to the posterior thoracic cage are needed.
OBJECTIVES
A novel scapulometer was developed to measure scapular medial border and inferior angle prominence.
METHODS
A novel scapulometer was designed to measure the distance from the root of the spine (ROS) and the inferior angle (INF) of the scapula to the thorax wall in 29 participants with scapular dyskinesis bilaterally. Two raters measured the ROS and INF distance of the scapula 3 times bilaterally. Intraclass correlation coefficients (ICC) and standard error of measurement (SEM) were calculated to determine the inter-rater and intra-rater reliability. Validity was based on correlations (convergent: ROS and internal/external rotation, and INF and tilt; divergent: ROS/INF and upward rotation of the scapula) using a FASTRAK Polhemus 3-D motion tracking system assessing scapular tilt, internal/external rotation, and upward/downward rotation.
RESULTS
The average ROS and INF displacements were 13.7 ± 5.0 mm and 12.5 ± 6.3 mm, respectively. The results showed excellent intra-rater and inter-rater reliability, with ICC = 0.88-0.99 and 0.95-0.99 (SEM = 0.7-0.8 mm), respectively. Correlations were 0.35/0.19 (convergent validity) and 0.07/0.09 (divergent validity).
CONCLUSIONS
The novel scapulometer has excellent reliability and fair validity to quantify medial border and inferior angle prominence of the scapula. Further research utilizing this instrument is recommended.
背景
先前的研究提出了多种评估肩胛骨运动障碍的方法。在临床上，需要设计评估工具来测量肩胛骨下角相对于胸后壁的后向位移。
目的
开发一种新的肩胛骨测量仪来测量肩胛骨内缘和下角的突出度。
方法
设计了一种新的肩胛骨测量仪，用于测量 29 名双侧肩胛骨运动障碍患者脊柱根部（ROS）和肩胛骨下角（INF）到胸壁的距离。两名评估者分别对双侧肩胛骨的 ROS 和 INF 距离进行了 3 次测量。计算组内相关系数（ICC）和测量标准误差（SEM），以确定评估者间和评估者内的可靠性。有效性基于 FASTRAK Polhemus 3-D 运动跟踪系统评估的肩胛骨倾斜度、内旋/外旋和上/下旋转的相关性（收敛性：ROS 和内/外旋转，INF 和倾斜；发散性：ROS/INF 和肩胛骨上旋）。
结果
平均 ROS 和 INF 位移分别为 13.7±5.0mm 和 12.5±6.3mm。结果显示评估者间和评估者内的可靠性均较好，ICC 分别为 0.88-0.99 和 0.95-0.99（SEM 分别为 0.7-0.8mm）。相关性分别为 0.35/0.19（收敛性）和 0.07/0.09（发散性）。
结论
新型肩胛骨测量仪具有良好的可靠性和可接受的有效性，可用于定量评估肩胛骨内缘和下角的突出度。建议进一步研究使用该仪器。
