Abstract: BACKGROUND: Patients with degenerative cervical spondylosis often suffer from changed varicosity of the cervical spine, unbalanced neck-shoulder muscular strength, and descending power.
OBJECTIVE: To probe into the correlation between sagittal curvature parameters and pain threshold for neck-shoulder muscles in degenerative cervical spondylosis.
METHODS: Totally 50 patients with degenerative cervical spondylosis received treatment at the 3D Printed Outpatient Center of Shanghai Ninth People’s Hospital, Shanghai Jiao Tong University School of Medicine from January 2022 to March 2023 were included in the study. After excluding the 10 patients of cervical lateral projection that failed to meet the measurement conditions, the cervical lateral projections were shot to measure the following iconography parameters: Borden value and C2-7 Cobb angle as well as pain thresholds on the midpoint of the superior trapezius muscle in bilateral bundles and at 1 cm beside the C5-6 interspike. The correlation between sagittal curvature parameters and pain threshold of neck-shoulder muscles in degenerative cervical spondylosis was analyzed.
RESULTS AND CONCLUSION: (1) The Borden value of sagittal curvature showed a moderately positive correlation with the bundle pain threshold in the left upper trapezius muscle, the bundle pain threshold in the right upper trapezius muscle, and the pain threshold at the 1 cm of the left side beside the C5-6 interspike (r=0.498, P < 0.01; r=0.448, P < 0.05; r=0.405, P < 0.05) and a weak positive correlation with the pain threshold at the 1 cm of the right side beside the C5-6 interspike (r=0.322, P < 0.05). (2) The C2-7 Cobb angle showed a weak positive correlation with the left squared myalgia threshold (r=0.355, P < 0.05), and there was no correlation with the pain threshold of the left trapezius muscle and the pain threshold at the 1 cm of both sides beside the C5-6 interspike. (3) There was a correlation between the pain threshold of the neck-shoulder muscles, and a high correlation between the pain threshold of the left and right muscles and the pain threshold within the left and right side muscles, indicating that the neck-shoulder muscles are consistent and may be related to the coordination of the neck-shoulder movements.
