背景冈上肌强化是肩部康复的重要组成部分。先前的研究已经确定，满罐和空罐练习可引起最大量的冈上肌活动。然而，在进行冈上肌练习时，并没有考虑肩胛骨的运动学。假设 与满罐运动相比，空罐运动期间肩胛骨下旋、内旋和前倾增加。研究设计 描述性实验室研究。方法 20 名参与者进行满罐和空罐练习，同时使用电磁跟踪系统收集三维肩胛运动数据。采用双向重复测量方差分析比较肱骨抬高上升期和下降期30°、60°和90°时的肩胛角。结果 在空罐运动期间，除了前/后倾斜的下降阶段 30° 外，所有采样的肱骨仰角都有更多的肩胛骨前倾和内旋 (P< .05)。结论 空罐练习时肩胛骨前倾和内旋增加，而肩胛骨上旋在练习之间没有差异。临床相关性 空罐运动期间，肩胛内旋和前倾的增加会减少冈上肌出口的体积。当维持肩峰下间隙很重要时，使用全罐运动似乎最适合选择性加强冈上肌。
Background Supraspinatus strengthening is an important component of shoulder rehabilitation. Previous work has determined that the full-can and empty-can exercises elicit the greatest amount of supraspinatus activity. However, scapular kinematics has not been considered when prescribing supraspinatus exercises. Hypothesis Scapular downward rotation, internal rotation, and anterior tipping during the empty-can exercise are increased when compared with the full-can exercise. Study Design Descriptive laboratory study. Methods Twenty participants performed full-can and empty-can exercises while an electromagnetic tracking system was used to collect three-dimensional scapular kinematic data. Scapular angles at 30 °, 60 °, and 90 ° of the ascending and descending phases of humeral elevation were compared using 2-way repeated measures analysis of variance. Results There was more scapular anterior tipping and internal rotation during the empty-can exercise at all sampled humeral elevation angles except at 30 ° of the descending phase for anterior/posterior tipping (P< .05). Conclusion Scapular anterior tipping and internal rotation are increased during the empty-can exercise, whereas scapular upward rotation was not different between exercises. Clinical Relevance Increased scapular internal rotation and anterior tipping decrease the volume of the supraspinatus outlet during the empty-can exercise. When maintenance of the subacromial space is important, use of the full-can exercise seems most appropriate for selective strengthening of the supraspinatus muscle.
