A total of 113 patients with posterior neck pain with or without radiating pain were analyzed. The kinematic sagittal parameters of cervical radiographs were obtained at the occipito\u2013cervical (O\u2013C2) angle, sagittal Cobb\u2019s angles of C1\u2013C2, C2\u2013C7, and sagittal vertical axis (SVA) of C1\u2013C7 and C2\u2013C7. Cervical disc degeneration was evaluated using the sum of Pfirrmann grades and total modified Matsumoto scores calculated from MRI of the cervical spine. A significant positive correlation was found for the C2\u2013C7 angle using the sum of the Pfirrmann grades and total modified Matsumoto scores, whereas the O\u2013C2 angle and the C1\u2013C2 angle were negatively correlated. The sagittal cervical parameters representing cervical kyphosis and jaw lifting posture were found to be significantly correlated with the degree of cervical disc degeneration. These findings suggest that the loss of the natural sagittal lordosis of the cervical spine may contribute to the progression of disc degeneration, rather than the forward head posture.<\/jats:p>","DOI":"10.1515\/med-2021-0219","type":"journal-article","created":{"date-parts":[[2021,2,5]],"date-time":"2021-02-05T22:26:23Z","timestamp":1612563983000},"page":"161-168","source":"Crossref","is-referenced-by-count":23,"title":["Correlation between kinematic sagittal parameters of the cervical lordosis or head posture and disc degeneration in patients with posterior neck pain"],"prefix":"10.1515","volume":"16","author":[{"given":"Hyo Jeong","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Rehabilitation Medicine, Gangnam Severance Hospital, Rehabilitation Institute of Neuromuscular Disease, Yonsei University College of Medicine , Seoul , Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dae Geun","family":"Jeon","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, Gangnam Severance Hospital, Rehabilitation Institute of Neuromuscular Disease, Yonsei University College of Medicine , Seoul , Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jung Hyun","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, Gangnam Severance Hospital, Rehabilitation Institute of Neuromuscular Disease, Yonsei University College of Medicine , Seoul , Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"374","published-online":{"date-parts":[[2021,1,22]]},"reference":[{"key":"2022091918191492788_j_med-2021-0219_ref_001","doi-asserted-by":"crossref","unstructured":"Scheer JK, Tang JA, Smith JS, Acosta FL, Protopsaltis TS, Blondel B, et al.
