颈椎定位旋转手法治疗颈痛患者的生物力学效应。本文通过实验获得头部运动学数据，将其导入已开发和验证的有限元模型，并计算和分析正常模型和病理模型中的角位移、关节盘压力和关节面接触力，分析了颈椎定位旋转手法的安全性。结果表明，颈椎定位旋转技术对颈椎C5-C6“肌腱出沟、骨性错位”病理模型的位置调整和施力更为有效。颈椎定位旋转手法与非定位情况相比，髓核压力变化较小。因此，在腰椎间盘退变患者中，颈椎定位旋转手法比非定位旋转手法具有更直接的机械效应，更安全。颈椎定位旋转手法是一种安全有效的治疗颈痛患者的方法。在病理模型的计算分析中得到了很好的证明。
Unlocking the biomechanical effects of cervical spine positioning rotation manipulation in the treatment of patients with neck pain. In this paper, the safety of the cervical positioning rotation manipulation is analyzed by experimentally obtaining head kinematic data, importing them into a finite element model that has been developed and validated, and calculating and analyzing the angular displacements, disc pressures, and articular surface contact forces in the normal and pathological models. The results show that the cervical spine positioning rotation technique is more effective in adjusting the position and applying force to the cervical spine C5-C6 "tendon out of the groove and bone misalignment" pathological model. Also, the cervical positioning rotation manipulation is applied with less variation in disc nucleus pulposus pressure than in the non-positioning situation. Thus, in patients with disc degeneration, cervical positioning rotational manipulation has a more direct mechanical effect and is safer than non-positioning rotational manipulation. The cervical spine positioning rotation manipulation is a safe method that can effectively treat patients with neck pain. It has been well demonstrated in the computational analysis of the pathological model.
