Background

The serratus anterior (SA) is capable of a wide range of actions across the scapulothoracic joint. Furthermore, the lack of control, strength, or activation of this important muscle is believed to be associated with several painful conditions involving the shoulder complex. Studies and clinical intuition have therefore identified several exercises that selectively target the activation of the SA.

Methods

This paper reviews the anatomy, innervation, testing, and complex actions of the SA. In addition, this paper describes the classic signs and symptoms of weakness or reduced activation of the SA. Several exercises are described and illustrated that purportedly target the activation of the SA, with the intention of optimizing muscular control and encouraging pain free shoulder motion.

Conclusions

This review provides the theoretical background and literature-based evidence that can help explain the SA's complex pathokinesiology, as well as guide the clinician to further develop exercises that likely challenge the muscle. This paper is written along with a companion paper entitled: Kinesiologic considerations for targeting activation of scapulothoracic muscles: part 2: trapezius. Both papers prepare the reader to expand their pallet of exercises that target and challenge these two dominant muscles, with a goal of improving function of the shoulder for several painful conditions caused by their reduced or altered activation pattern.

靶向激活肩oth动脉肌肉的运动学考虑因素-第1部分：前锯肌。

背景

前锯肌（SA）能够跨肩oth孔联合关节进行多种动作。此外，据信缺乏对这一重要肌肉的控制，力量或激活，这与涉及肩部复合体的几种疼痛状况有关。因此，研究和临床直觉确定了几种选择性针对SA激活的运动。

方法

本文回顾了SA的解剖，神经支配，测试和复杂的动作。此外，本文还介绍了SA衰弱或激活减少的经典体征和症状。描述和说明了一些练习，这些练习据称针对SA的激活，旨在优化肌肉控制并鼓励无痛肩膀运动。

结论

这篇综述提供了理论背景和基于文献的证据，可以帮助解释SA的复杂病理运动学，并指导临床医生进一步开展可能挑战肌肉的锻炼。本文与随附的论文一起撰写，题为：靶向激活肩oth动脉肌肉的运动学考虑因素：第2部分：斜方肌。这两篇论文都为读者准备了扩展针对和挑战这两种主要肌肉的运动的平台，目的是针对因其减少或改变的激活方式而导致的几种疼痛情况改善肩部功能。
