Electromagnetic tracking systems have enabled some investigators and clinicians to measure tri-planar scapular motion; yet, they are not practical and affordable options for all clinicians. Currently, the ability to affordably quantify scapular motion is limited to monitoring only the motion of scapular upward rotation, with use of a digital inclinometer.
HYPOTHESIS/PURPOSE: The objective of this study was to determine the criterion-related validity of a modified digital inclinometer when used to measure the motion of scapular anterior-posterior (AP) tilt.
MATERIALS & METHODS: Thirteen volunteers, free from any history of shoulder injury, reported for a single testing session. Each subject underwent a brief shoulder and posture examination in order to confirm the absence of pathology. Subjects actively performed clinically relevant amounts of humeral elevation in the scapular plane while in a seated position. An electromagnetic tracking system (Ascension Technology, Burlington, VT) and a modified inclinometer (Pro 360, Baseline®, Fabrication Enterprises, White Plains, NY) were used to acquire scapular AP tilt over the same shoulder motions. Criterion-related validity was determined using Pearson Product Moment correlations.
Correlation analyses revealed significant moderate to good associations (r = 0.63 to 0.86, p < 0.01) between scapular AP tilt measures obtained with a digital inclinometer and an electromagnetic tracking system.
A modified digital inclinometer is a moderately valid device to use for the quantification of scapular AP tilt. Further study is warranted to establish reliability and to validate use of the device in patients with shoulder injury or pathology. The modified inclinometer expands the clinician's ability to quantify scapular kinematic motion during the clinical evaluation and rehabilitation process.

电磁跟踪系统使一些研究人员和临床医生能够测量肩胛骨的三维运动；然而，对于所有临床医生来说，它们并非实用且经济实惠的选择。目前，以经济实惠的方式量化肩胛骨运动的能力仅限于使用数字倾角仪监测肩胛骨上旋运动。
假设/目的：本研究的目的是确定一种改良数字倾角仪用于测量肩胛骨前后（AP）倾斜运动时的标准关联效度。
13名无肩部损伤史的志愿者参加了一次测试。每位受试者都接受了简短的肩部和姿势检查，以确认无病理情况。受试者坐在座位上，在肩胛骨平面内主动进行临床上相关程度的肱骨抬高动作。使用电磁跟踪系统（Ascension Technology，佛蒙特州伯灵顿）和改良倾角仪（Pro 360，Baseline®，Fabrication Enterprises，纽约州怀特普莱恩斯）在相同的肩部运动中获取肩胛骨AP倾斜度。使用皮尔逊积矩相关性确定标准关联效度。
相关性分析显示，数字倾角仪和电磁跟踪系统测得的肩胛骨AP倾斜度测量值之间存在显著的中度到良好关联（r = 0.63至0.86，p < 0.01）。
改良数字倾角仪是一种用于量化肩胛骨AP倾斜度的中度有效设备。有必要进一步研究以确定其可靠性，并验证该设备在肩部损伤或病理患者中的使用。改良倾角仪扩展了临床医生在临床评估和康复过程中量化肩胛骨运动学运动的能力。
