Abstract
UNLABELLED
The overhead pitching motion is described as a coordinated sequence of body movements and muscular forces that have an ultimate goal of achieving high ball velocity and target accuracy. An understanding of the dynamic overhead throwing motion outlined in this clinical commentary can assist the clinician in addressing the unique injuries experienced by the pitcher. The potential biomechanical sources for injury have been studied utilizing videography and electromyographic techniques due to the rapid pace with which the pitching motion occurs. This clinical comentary will describe what is widely accepted as the six phases of the pitching motion and the relationship to the kinetic chain theory as well as outline the common mechanical faults that can lead to increased tissue stress and potential injury.

过头投球动作被描述为一系列协调的身体动作和肌肉力量，其最终目标是实现高球速和目标准确性。理解本临床评论中概述的动态过头投球动作可帮助临床医生处理投手所经历的独特损伤。由于投球动作发生速度很快，已利用摄像和肌电图技术研究了潜在的生物力学损伤源。本临床评论将描述被广泛认可的投球动作的六个阶段及其与动力链理论的关系，并概述可能导致组织应力增加和潜在损伤的常见机械错误。
