通过建立脊柱前屈的力学模型，定量计算腰骶椎间盘承受的应力。
Based on mechanics model of spinal flexion, stress upon lumber intervertebral disc was quantitatively calculated.
就像一辆车减速一样，在后弯之后前屈之前，脊柱也需要一些时间来恢复到中立状态。
Like a car gearing down, the spine needs some time to return to neutral after back bending before moving into forward bending.
犁式，肩倒立和坐立或站立前屈集中脊柱的压缩，导致损伤。
Plow, shoulder stand and seated or standing forward bends concentrate compression forces on the spine, which can lead to injury.
结果：两组颈部及脊柱周围软组织压痛均有明显改善（P<0.05），治疗后两组颈前屈、后伸、左右侧屈及左右旋转活动度加大（P<0.05）。
Results:Surrounding soft tissues tenderness of neck and spinal were obviously improved (P<0.05). ROM of neck in both groups after therapy were improved as well(P<0.05).
如果它能得到躯干前侧和后侧肌肉的辅助从而波动住身体，特别是保持脊柱屈度的全体性，那是最好的。
It works best if it has help from the muscles at the front and the back of the torso to help keep the body properly aligned, especially when it comes to maintaining the integrity of the spinal curves.
方法采用脊柱活动节段的三维有限元模型分析了脊柱在直立位、前屈位和后伸位的应力分布情况。
Methods Stress distribution of the spine in the upright, flexion and extension positions was analyzed using a three-dimensional finite element model of the spinal motion segment.
