背景：肩峰下疼痛综合征(SPS)是肩部疼痛的常见原因，肌肉活动缺陷被认为与疾病的发生和发展有关。方法：检索6个数据库：Medline、EMBASE、CINAHL、SPORTdisus、PEDRO和Cochrane图书馆(启动至2016年5月)。搜索得到了1414条记录，使用了与肩部撞击、肌电、肩胛肌和肩袖肌肉相关的术语。一旦删除重复项并应用选择标准，仍有22篇论文。进行数据提取、质量评价和数据合成。结果：有限的证据表明，在SPS参与者中，前锯齿肌波幅较低，激活延迟，终止时间较早。对于大多数肌肉，无论任务、负荷或手臂位置，都没有表现出显著的差异或结果相互矛盾。结论：对SPS的理解正在改变，EMG似乎无法捕捉到与这种情况相关的复杂性。解决异常运动模式和促进所有肩部肌肉的平衡激活可能是未来更合适的治疗方向。
BACKGROUND: Subacromial pain syndrome (SPS) is a common cause of shoulder pain and muscle activity deficits are postulated to contribute to the development and progression of the disorder. The purpose of this systematic review was to definitively determine whether evidence exists of differences in electromyography (EMG) characteristics between subjects with and without SPS.METHODS: Six key databases were searched: MEDLINE, EMBASE, CINAHL, SPORTdiscus, PEDro and The Cochrane Library (inception to May 2016). The search yielded 1414 records using terms relating to shoulder impingement, EMG, scapular and rotator cuff muscles. Twenty-two papers remained once duplicates were removed and selection criteria applied. Data extraction, quality assessment and data synthesis were performed. Effect sizes and 95% confidence intervals were calculated.RESULTS: There was limited evidence that serratus anterior has lower amplitude, delayed activation and earlier termination in SPS participants. For the majority of muscles, regardless of task, load or arm position, significant differences were not demonstrated or results were contradictory.CONCLUSIONS: The understanding of SPS is changing and EMG appears unable to capture the complexities associated with this condition. Addressing aberrant movement patterns and facilitating balanced activation of all shoulder muscles may be a more appropriate treatment direction for the future.
