This study aimed to evaluate the reliability of the RSQ Motion sensor and its validity against the Propriometer and electronic goniometer in measuring the active range of motion (ROM) of the shoulder. The study included 15 volunteers (mean age 24.73 ± 3.31) without any clinical symptoms with no history of trauma, disease, or surgery to the upper limb. Four movements were tested: flexion, abduction, external and internal rotation. Validation was assessed in the full range of active shoulder motion. Reliability was revised in full active ROM, a fixed angle of 90 degrees for flexion and abduction, and 45 degrees for internal and external rotation. Each participant was assessed three times: on the first day by both testers and on the second day only by one of the testers. Goniometer and RSQ Motion sensors showed moderate to excellent correlation for all tested movements (ICC 0.61-0.97, LOA < 23 degrees). Analysis of inter-rater reliability showed good to excellent agreement between both testers (ICC 0.74-0.97, LOA 13-35 degrees). Analysis of intra-rater reliability showed moderate to a good agreement (ICC 0.7-0.88, LOA 22-37 degrees). The shoulder internal and external rotation measurement with RSQ Motion sensors is valid and reliable. There is a high level of inter-rater and intra-rater reliability for the RSQ Motion sensors and Propriometer.
本研究旨在评估 RSQ Motion 传感器的可靠性，并验证其在测量肩部主动活动范围（ROM）方面的有效性，与 Propriometer 和电子量角器进行对比。研究纳入了 15 名志愿者（平均年龄 24.73±3.31 岁），均无临床症状，且上肢无创伤、疾病或手术史。共测试了四个运动：屈曲、外展、外旋和内旋。在肩部主动活动的全范围内评估验证，在全主动 ROM、屈曲和外展 90 度的固定角度以及内旋和外旋 45 度的固定角度下评估可靠性。每位参与者评估了三次：第一天由两位测试者进行，第二天仅由其中一位测试者进行。量角器和 RSQ Motion 传感器在所有测试运动中均显示出中等到极好的相关性（ICC 0.61-0.97，LOA<23 度）。分析组内可靠性显示两位测试者之间具有良好到极好的一致性（ICC 0.74-0.97，LOA 13-35 度）。分析组内可靠性显示具有中等到良好的一致性（ICC 0.7-0.88，LOA 22-37 度）。RSQ Motion 传感器测量肩部内旋和外旋是有效且可靠的。RSQ Motion 传感器和 Propriometer 具有高度的组内和组间可靠性。
