摘要：



文题释义：
表面肌电图：是一种非侵入性的检测技术，它通过皮肤表面记录肌肉活动时神经肌肉系统产生的生物电变化信号。这种技术能够提供关于肌肉募集与去募集能力、疲劳、协同激活、协同收缩的信息，对于评估肩胛骨肌肉功能状态具有重要意义，有助于理解肩胛骨运动障碍的发生机制。
肩袖撕裂：是指肩关节周围的肌腱(肩袖)发生部分或完全撕裂，这可能导致肩关节疼痛和功能障碍。肩袖由冈上肌、冈下肌、小圆肌及肩胛下肌的肌腱组成，它们跨越肩关节上方，对肩关节的稳定性和运动功能至关重要。肩袖撕裂常伴有肩胛骨运动障碍。

背景：肩袖撕裂是一种常见的肩关节疾病，严重影响患者的生活质量。表面肌电图可以提供肌肉运动时的电生理信息，目前有不少研究将表面肌电图用于评估肩胛骨运动状态，其研究多集中于运动员、偏瘫患者等特殊人群，但在肩袖撕裂患者中的应用尚不多见。
目的：采用表面肌电图检测，比较正常人及肩袖撕裂患者肩胛骨周围肌肉的运动模式差异，探讨肩袖撕裂患者肩胛骨运动障碍的发生机制，为建立临床康复训练方法提供依据。
方法：选择2021年9月至2023年2月在上海中医药大学附属光华医院就诊的小型肩袖撕裂患者40例纳入试验组，并设置无肩关节疾病的对照组40例。统计人口学和临床资料，使用表面肌电检测，运用最大主动等长收缩法(MVIC)，在患者肩关节前屈、外展、体侧外旋时，进行上斜方肌、中斜方肌、下斜方肌和前锯肌的%MVIC测试，每个动作重复测试3次，计算上斜方肌/下斜方肌、上斜方肌/中斜方肌和上斜方肌/前锯肌的%MVIC平均值比值，并进行组间对比。
结果与结论：①与对照组相比，试验组在进行前屈、外展、体侧外旋3个动作时，上斜方肌/下斜方肌、上斜方肌/中斜方肌、上斜方肌/前锯肌的%MVIC比值均明显升高，差异有显著性意义(均P < 0.05)；②结果表明，肩袖撕裂患者的肩胛骨运动障碍机制可能是斜方肌和前锯肌被过度激活，从而导致运动失衡。

Abstract: BACKGROUND: Rotator cuff tears are a prevalent condition affecting the shoulder joint, which can substantially diminish a patient’s quality of life. Surface electromyography is a diagnostic technique that captures the electrophysiological signals of muscles during movement. Most of its studies have focused on special populations such as athletes and hemiplegic patients, but its use in patients with rotator cuff tears is still rare.
OBJECTIVE: To compare the differences in the movement patterns of the muscles around the scapula between normal subjects and patients with rotator cuff tears using surface electromyography and to investigate the pathogenetic mechanisms of scapular dyskinesia in patients with rotator cuff tears, thereby providing a basis for the establishment of clinical rehabilitation protocol. 
METHODS: From September 2021 to February 2023, 40 patients with rotator cuff tears who met the enrolled criteria at Guanghua Hospital affiliated to Shanghai University of Chinese Medicine were included in the trial group, and a control group without shoulder disease (n=40) was set. Demographic and clinical data were obtained using surface electromyography. Using the maximal voluntary isometric contraction (MVIC) method, the %MVIC of the upper trapezius, middle trapezius, lower trapezius, and serratus anterior muscles was measured during shoulder flexion, abduction, and external rotation at the side. Each movement was tested thrice, and the average %MVIC ratios of upper trapezius/lower trapezius, upper trapezius/middle trapezius, and upper trapezius/serratus anterior were calculated for intergroup comparison.
RESULTS AND CONCLUSION: Compared with the control group, the trial group showed significantly higher %MVIC ratios of upper trapezius/lower trapezius, upper trapezius/middle trapezius, and upper trapezius/serratus anterior during shoulder flexion, abduction, and external rotation at the side (all P < 0.05). To conclude, the mechanism of scapular dyskinesis in patients with rotator cuff tears may involve overactivation of the trapezius and serratus anterior muscles, resulting in movement imbalance.
