To measure the scapulohumeral rhythm (SHR) in outpatient settings, the motion analysis protocol named ISEO (INAIL Shoulder and Elbow Outpatient protocol) was developed, based on inertial and magnetic sensors. To complete the sensor-to-segment calibration, ISEO requires the involvement of an operator for sensor placement and for positioning the patient's arm in a predefined posture. Since this can affect the measure, this study aimed at quantifying ISEO intra- and inter-operator agreement. Forty subjects were considered, together with two operators, A and B. Three measurement sessions were completed for each subject: two by A and one by B. In each session, the humerus and scapula rotations were measured during sagittal and scapular plane elevation movements. ISEO intra- and inter-operator agreement were assessed by computing, between sessions, the: (1) similarity of the scapulohumeral patterns through the Coefficient of Multiple Correlation (CMC(2)), both considering and excluding the difference of the initial value of the scapula rotations between two sessions (inter-session offset); (2) 95% Smallest Detectable Difference (SDD(95)) in scapula range of motion. Results for CMC(2) showed that the intra- and inter-operator agreement is acceptable (median≥0.85, lower-whisker ≥ 0.75) for most of the scapula rotations, independently from the movement and the inter-session offset. The only exception is the agreement for scapula protraction-retraction and for scapula medio-lateral rotation during abduction (inter-operator), which is acceptable only if the inter-session offset is removed. SDD(95) values ranged from 4.4° to 8.6° for the inter-operator and between 4.9° and 8.5° for the intra-operator agreement. In conclusion, ISEO presents a high intra- and inter-operator agreement, particularly with the scapula inter-session offset removed.
为了在门诊环境中测量肩肱节律（SHR），基于惯性和磁力传感器，开发了名为 ISEO（意大利国家职业安全与健康研究所肩部和肘部门诊协议）的运动分析协议。为了完成传感器到节段的校准，ISEO 需要操作员参与放置传感器和将患者手臂定位在预定义姿势中。由于这可能会影响测量结果，因此本研究旨在量化 ISEO 的内部和操作员之间的一致性。考虑了 40 名受试者和两名操作员 A 和 B。每位受试者完成了三次测量：A 完成了两次，B 完成了一次。在每次测量中，测量了肱骨和肩胛骨在矢状面和肩胛骨平面抬高运动中的旋转。通过计算会话之间的：（1）通过多相关系数（CMC(2)）评估肩胛骨模式的相似性，同时考虑和不考虑两次会话之间肩胛骨旋转初始值的差异（会话间偏移）；（2）在肩胛骨运动范围中 95%最小可检测差异（SDD(95)），评估 ISEO 内部和操作员之间的一致性。CMC(2)的结果表明，大多数肩胛骨旋转的内部和操作员之间的一致性是可以接受的（中位数≥0.85，下限≥0.75），独立于运动和会话间偏移。唯一的例外是肩胛骨前伸-后缩和外展时肩胛骨中外旋转的协议（操作员之间），如果去除会话间偏移，则是可以接受的。SDD(95)值在操作员之间为 4.4°至 8.6°，在操作员内部为 4.9°至 8.5°。总之，ISEO 具有较高的内部和操作员之间的一致性，特别是在去除了会话间偏移之后。
