The shoulder's ability to participate in sports and activities of daily living depends on its active range of motion. Clinical goniometry is of limited utility in rigorously assessing limitation of motion and the effectiveness of treatment. We sought to determine (1) whether a validated position-sensing tool, the Kinect, can enable the objective clinical measurement of shoulder motion and (2) the degree to which active range of motion correlates with patient self-assessed shoulder function.
In 10 control subjects, we compared Kinect motion measurements to measurements made on standardized anteroposterior and lateral photographs taken concurrently. In 51 patients, we correlated active motion with the ability to perform the functions of the Simple Shoulder Test (SST).
In controls, Kinect measurements strongly agreed with photographic measurements. In patients, the total SST score was strongly correlated with the range of active abduction. The ability to perform each of the individual SST functions was strongly correlated with active motion. The active motion in well-functioning patient shoulders averaged 155° ± 22° abduction, 159° ± 14° flexion, 76° ± 18° external rotation in abduction, -59° ± 25° internal rotation in abduction, and -3.3 ± 3.7 inches of cross-body adduction, values similar to the control shoulders. Use of the Kinect system was practical in clinical examination rooms, requiring <5 minutes to document the 5 motions in both shoulders.
The Kinect provides a clinically practical method for objectively measuring active shoulder motion. Active motion was an important determinant of patient-assessed shoulder function.
肩部参与体育活动和日常生活活动的能力取决于其主动活动范围。临床角度测量法在严格评估运动受限情况和治疗效果方面效用有限。我们试图确定：（1）一种经过验证的位置传感工具——Kinect，是否能够实现肩部运动的客观临床测量；（2）主动活动范围与患者自我评估的肩部功能之间的关联程度。
在10名对照受试者中，我们将Kinect测量结果与同时拍摄的标准化前后位和侧位照片测量结果进行比较。在51名患者中，我们将主动运动与简单肩部测试（SST）功能执行能力进行关联分析。
在对照受试者中，Kinect测量结果与照片测量结果高度一致。在患者中，SST总分与主动外展范围高度相关。执行每项SST功能的能力与主动运动高度相关。功能良好的患者肩部主动运动平均外展155°±22°，屈曲159°±14°，外展时外旋76°±18°，外展时内旋-59°±25°，体侧内收-3.3±3.7英寸，这些值与对照肩部相似。在临床检查室中使用Kinect系统切实可行，记录双肩的5项运动所需时间不到5分钟。
Kinect提供了一种客观测量肩部主动运动的临床实用方法。主动运动是患者评估肩部功能的重要决定因素。
