对胸部和腹部脏器钝性撞击伤的物理机制通常被简单地描述为“挤压”——这是一种过于简单化的描述。对躯干的任何冲击都会导致体壁的快速位移，这可能会撕裂和挫伤下面的内脏，但这种简单的解释并不能解释距离接触点一定距离的部位的病理情况，也不能充分描述损伤的严重程度和位置对能量转移速度的依赖性。如果体壁速度很高，很小的体壁位移可能会造成严重的伤害。体壁的运动产生的波在体内传播，并将能量传递到内部部位。这些波的性质和性质进行了简单的讨论，并提出了波的作用，在生产的特征伤害，造成的冲击躯干。
The physical mechanism of blunt impact injuries to thoracic and abdominal viscera is often conveniently described simply in terms of "crush"--this is an over-simplification. Any impact to the torso does result in the rapid displacement of the body wall which may lacerate and contuse underlying viscera, but this simple explanation does not account for pathology at sites some distance from the contact point and does not adequately describe the dependence of the severity and location of injury upon the rate of energy transfer. Quite minor displacements of the body wall may produce serious injury if the body wall velocity is high. The motion of the body wall generates waves that propagate within the body and transfer energy to internal sites. The nature and properties of these waves are discussed in simple terms and the role of waves in the production of the characteristic injuries resulting from impact to the torso is presented.
