The results showed that the stress was gradually increasing along with the increasing Angle and strength oftraction.
结果显示随着牵引角度加大和牵引重量的增加，腰椎间盘各部拉应力逐渐加大。

When the tractionAngle was constant, the displacement and stress of the cervical column as well as the deformation of intervertebral space were all increased with the enhancing of traction force.
当牵引角度不变时，随牵引力的增大，颈椎的位移及各点的应力均增大，椎间隙的形变亦更明显。

Stubbs stretch traction control is the key to pulling stretch of cervical traction when the Angleof flexion and traction, and patients quickly and efficiently to help solve the disease problems.
