PURPOSE
This study examined the cervical spine range of motion (ROM) resulting from whiplash-type hyperextension and hyperflexion type ligamentous injuries, and sought to improve the accuracy of specific diagnosis of these injuries.
METHODS
The study was accomplished by measurement of ROM throughout axial rotation, lateral bending, and flexion and extension, using a validated finite element model of the cervical spine that was modified to simulate hyperextension and/or hyperflexion injuries.
RESULTS
It was found that the kinematic difference between hyperextension and hyperflexion injuries was minimal throughout the combined flexion and extension ROM measurement that is commonly used for clinical diagnosis of cervical ligamentous injury. However, the two injuries demonstrated substantially different ROM under axial rotation and lateral bending.
CONCLUSIONS
It is recommended that other bending axes beyond flexion and extension are incorporated into clinical diagnosis of cervical ligamentous injury.
目的
本研究检测了挥鞭样过伸和过屈型韧带损伤导致的颈椎活动范围（ROM），并试图提高这些损伤的特异性诊断准确性。
方法
本研究通过在轴向旋转、侧弯以及屈伸过程中测量ROM来完成，使用经过验证的颈椎有限元模型，该模型经过修改以模拟过伸和/或过屈损伤。
结果
发现在通常用于颈椎韧带损伤临床诊断的屈伸ROM联合测量中，过伸和过屈损伤之间的运动学差异极小。然而，在轴向旋转和侧弯时，这两种损伤表现出明显不同的ROM。
结论
建议将屈伸以外的其他弯曲轴纳入颈椎韧带损伤的临床诊断中。
