TLDR
The results suggest that static radiographs cannot accurately represent vertebral orientation during dynamic motion and data should be collected during both flexion and extension movements when investigating intervertebral kinematics with respect to global head orientation.About:

Three-dimensional intervertebral kinematics in the healthy young adult cervical spine during dynamic functional loading.
TL;DR: This study provides valuable reference data for evaluating the effects of age, degeneration, and surgical procedures on cervical spine kinematics during three-dimensional dynamic functional loading.
Journal ArticleDOI
In vivo three-dimensional intervertebral kinematics of the subaxial cervical spine during seated axial rotation and lateral bending via a fluoroscopy-to-CT registration approach.
TL;DR: The observed coupling characteristics of the intervertebral kinematics were different from those in previous studies under discrete static conditions in a supine position without weight-bearing, suggesting that the testing conditions likely affect the kinematic of the subaxial cervical spine.

Cervical motion segment contributions to head motion during flexion\extension, lateral bending, and axial rotation
TL;DR: The clinical implication of increased contributions from the inferior motions segments near the end ROM is that the clinician may advise the patient to avoid end ROM positions to lessen the demand on the discs of inferior motion segments.
Basic Science Cervical motion segment contributions to head motion during flexion\extension, lateral bending, and axial rotation
TL;DR: In this paper, the cervical spine segmental contribu- tions to head flexion, lateral bending and axial rotation during dynamic motion in young, healthy individuals were determined continuously during each of the three head movements.

TL;DR: The results suggest that the paraspinal muscles of the lumbar spine play an important role in adjacent segment loading of a spinal fusion, independent of the presence of rigid spinal instrumentation.

ISB recommendation on definitions of joint coordinate systems of various joints for the reporting of human joint motion-Part II: shoulder, elbow, wrist and hand

TL;DR: A definition of a joint coordinate system (JCS) for the shoulder, elbow, wrist, and hand is proposed and a standard for the local axis system in each articulating segment or bone is generated.

TL;DR: The Standardization and Terminology Committee (STC) of the International Society of Biomechanics proposes definitions of JCS for the ankle, hip, and spine, and suggests that adopting these standards will lead to better communication among researchers and clinicians.

Abnormal magnetic-resonance scans of the lumbar spine in asymptomatic subjects. A prospective investigation
TL;DR: In this paper, the authors performed magnetic resonance imaging on sixty-seven individuals who had never had low-back pain, sciatica, or neurogenic claudication, and found that about one-third of the subjects were found to have a substantial abnormality.
