Methods. A 3-dimensional, nonlinear finite element model of a lumbar spinalsegment L4-L5 was used.
方法：我们使用了一个关于L4-L5腰椎的3维非线性有限元素法的模型。

Inhale, and start at tail bone and raise on spinalsegment at a time until weight is supported on feet and shoulders.
吸气，从骶骨开始逐节抬起脊柱，直到由脚部和肩部支撑所有身体重量。

It can alter the biomechanics of weight transfer at the affected spinalsegment, accelerate the regression of discs and eventually cause the emergence of LDH.
