To study the correlation between cervical (rotation) traction force and the pressure in the cervical nucleus pulposus based on an examination of multiple segments of the cervical vertebra.
The data obtained from our observation were processed by the exponential model, and the changes in the pressure reduction (P) in the cervical nucleus pulposus were analyzed.
When stretching followed by rotation was imposed on the cervical vertebra, an increase of P was first observed due to the stretching before a reduction in P caused by the rotation. The P of C(3-4) segments was constantly greater than that of C(5-6) segments, while the changes in P of C(4-5) followed different patterns.
Changes of P in each segment of the cervical vertebra are similar in response to the load force, and there is no correlation of monotonic increase or decrease between the changes of P and the location of the cervical vertebra.
通过对颈椎多个节段的检查，研究颈椎（旋转）牵引力与颈椎髓核压力之间的相关性。
对观察获得的数据采用指数模型进行处理，并分析颈椎髓核减压（P）的变化。
对颈椎先进行伸展然后旋转时，首先观察到由于伸展导致P增加，之后由于旋转导致P降低。C（3 - 4）节段的P始终大于C（5 - 6）节段，而C（4 - 5）节段的P变化遵循不同模式。
颈椎各节段P的变化对负荷力的反应相似，且P的变化与颈椎位置之间不存在单调增加或减少的相关性。
