Abstract

Purpose: The purpose of this study is to determine the relationship between the repetitive flexion or extension posture on the cervical spine on labor and degenerative change of the cervical spine, and the factors affecting degenerative change of the cervical spine.
Materials and Methods: To determine the factors affecting degenerative change of the cervical spine, age, sex, height, weight, body mass index, smoking, diabetes mellitus (DM), time engaging in labor, and cervical spine posture (flexion or extension) required repetitively on labor were investigated in the subjects. In addition, to evaluate the level of degenerative change of the cervical spine on 83 people in the flexion group (flexion strain) and 83 people in the extension group (extension strain), cervical degenerative index (CDI) in the simple cervical spine lateral radiograph was used to score (0-60 points) the degenerative severity.
Results: A total of 166 subjects (flexion group: 83 people, extension group: 83 people) participated in this study, and for the CDI, the cervical spine flexion group scored 7.8±6.2 points, and the cervical spine extension group scored 12.2±6.0 points to show that the cervical spine extension group had significant degenerative change in the cervical spine. In the multiple linear regression test performed to verify the risk factors affecting the degenerative change of the cervical spine, age (p=0.004), contraction of DM (p=0.029), and extension posture of cervical spine (p<0.001) influenced the degenerative change of the cervical spine.
Conclusion: Repetitive extension posture on the cervical spine on labor and contraction of diabetes affected degenerative change of the cervical spine, therefore, training in medical care and posture on labor are required to prevent the progression of degenerative change in the cervical spine.
