(orcid)0000-0001-8292-6613 In vitro upper cervical spine kinematics: rotation with combined movements and its variation after alar ligament transection 2022 Access copy available to the general public Unrestricted Previous studies indicate that maximum upper cervical axial rotation occurs only through a combination of transverse, frontal, and sagittal plane motions. This study explores the relationship between transection of the alar ligament and combined upper cervical axial rotation movements. Ten cryopreserved upper cervical spines were manually mobilized in bilateral axial rotation and two different motion combinations with simultaneous motion in the three anatomical planes: rotation in extension (extension + axial rotation + contralateral lateral bending) and rotation in flexion (flexion + axial rotation + ipsilateral lateral bending). These three motions were performed before and after right alar ligament transection. The occiput-axis axial rotation was measured using an optical motion capture system while measuring the applied load. With intact alar ligament, the axial rotation in flexion showed the lowest range of motion (right, R: 9.81 ± 3.89°; left, L: 15.54 ± 5.89°). Similar results were found between the other two mobilizations: axial rotation (R: 33.87 ± 6.64°; L: 27.99 ± 6.90°) and rotation in extension (R: 35.15 ± 5.97°; L: 28.96 ± 6.47°). After right alar ligament transection, rotation in flexion (particularly in left rotation) showed the largest increase in motion: rotation in flexion (R: 13.78 ± 9.63°; L: 23.04 ± 5.59°), rotation in extension (R: 36.39 ± 7.10°; L: 31.71 ± 7.67°), and axial rotation (R: 38.50 ± 9.47°; L: 31.59 ± 6.55°). Different combinations of movements should be evaluated when analyzing the maximum axial rotation of the upper cervical spine, as axial rotation alone and rotation in extension showed a larger range of motion than rotation in flexion. After unilateral alar ligament injury, rotation to the non-injured side in flexion demonstrates the most movement increase. info:eu-repo/grantAgreement/ES/DGA/T38-17R info:eu-repo/semantics/openAccess by-sa http://creativecommons.org/licenses/by-sa/3.0/es/ 2.4 2022 ENGINEERING, BIOMEDICAL 67 / 96 = 0.698 2022 Q3 T3 BIOPHYSICS 46 / 70 = 0.657 2022 Q3 T2 0.699 2022 Rehabilitation 2022 Q1 Biophysics 2022 Q2 Sports Science 2022 Q2 Biomedical Engineering 2022 Q2 Orthopedics and Sports Medicine 2022 Q2 4.9 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Hidalgo-García, César Universidad de Zaragoza (orcid)0000-0001-7667-2178 Fanlo-Mazas, Pablo Universidad de Zaragoza (orcid)0000-0003-3472-072X Rodríguez-Sanz, Jacobo López-de-Celis, Carlos Krauss, John Maza-Frechín, Mario Universidad de Zaragoza (orcid)0000-0003-1261-8847 Tricás-Moreno, José Miguel Universidad de Zaragoza (orcid)0000-0002-3583-5206 Pérez-Bellmunt, Albert 5004 530 Universidad de Zaragoza Dpto.
