背景对于肩部疾病患者，建议进行包括髋部或躯干运动在内的动力链练习。然而，这些练习的实际肌肉激活和肩胛运动学尚不清楚。本研究的目的是检查躯干旋转对旨在改善肩胛功能的肩部运动的影响。方法 13 名健康的年轻男性参与了这项研究。在有或没有躯干旋转的情况下进行肩胛下翻、第一位置和第二位置的外旋以及肩胛外展45°、90°和145°的俯卧位肩胛骨回缩。肌电图用于评估上斜方肌（UT）、中斜方肌（MT）、下斜方肌（LT）和前锯肌（SA）的肩胛肌活动，电磁运动捕捉用于评估肩胛骨运动。计算肌肉活动比率，即 UT 与 MT、LT 和 SA 的活动。这些数据在每次练习的 2 种条件（有和没有躯干旋转）之间进行比较。结果将躯干旋转添加到肩胛骨旋转中，第一次外旋和第二次外旋显着增加了肩胛骨外旋和后倾，并且所有 3 种练习都增加了 LT 激活。此外，在肩外展90°和145°处进行肩胛骨后缩的躯干旋转可显着降低UT/LT比率。结论我们的研究结果表明，本研究中的躯干旋转肩部运动对于难以增强LT活动和抑制UT过度激活的患者或观察到肩胛骨外旋或后倾减少的患者可能有效。
BackgroundIn patients with shoulder disease, kinetic chain exercises including hip or trunk movement are recommended. However, the actual muscle activation and scapular kinematics of these exercises are not known. The purpose of this study was to examine the effect of trunk rotation on shoulder exercises that are devised to improve scapular function.MethodsThirteen healthy young men participated in this study. Scaption, external rotation in the first and second positions, and prone scapular retraction at 45°, 90°, and 145° of shoulder abduction were performed with and without trunk rotation. Electromyography was used to assess the scapular muscle activity of the upper trapezius (UT), middle trapezius (MT), lower trapezius (LT), and serratus anterior (SA), and electromagnetic motion capture was used to assess scapular motion. The muscle activity ratio, which is the activity of the UT to the MT, LT, and SA, was calculated. These data were compared between 2 conditions (with and without trunk rotation) for each exercise.ResultsAdding trunk rotation to scaption, the first external rotation, and the second external rotation significantly increased scapular external rotation and posterior tilt, and all 3 exercises increased LT activation. In addition, trunk rotation with scapular retraction at 90° and 145° of shoulder abduction significantly decreased the UT/LT ratio.ConclusionsOur findings suggest that shoulder exercises with trunk rotation in this study may be effective in patients who have difficulty in enhancing LT activity and suppressing excessive activation of the UT or in cases in which a decreased scapular external rotation or posterior tilt is observed.
