Cervical Spine

Adjacent Segment Mechanics in Cervical Arthrodesis Patients

This NIH-funded prospective study aims to identify the factors that have the greatest effect on adjacent segment mechanics after cervical fusion. A total of 88 anterior cervical fusion patients will be tested prior to surgery, and 1 and 3 years after surgery.  Participants will perform full range of motion flexion/extension and rotation while biplane radiographs are collected at 30 images per second for each movement trial.

Intervertebral Kinematics in the Cervical Spine Before, During and After High-Velocity Low-Amplitude (HVLA) Mobilization

This study was designed to characterize the three-dimensional intervertebral kinematics of the cervical spine before, during, and after spinal manipulation. This study has the potential to reveal important associations between altered spine kinematics, painful/restricted cervical segmental range of motion, and the painless/unrestricted segmental motion typically seen immediately post-manipulation. This is a quantitative descriptive study to measure intervertebral kinematics (translations and rotations) before, during, and after HVLA cervical spine manipulation. This exploratory study focuses exclusively on individuals with nonspecific neck pain.
