To investigate the differences of spinal curvature, thoracic sagittal mobility, and respiratory strength between patients with chronic neck pain (CNP) and people without cervical pain, and to determine the correlation between respiratory strength and thoracic mobility in CNP patients.
A total of 78 participants were finally included in this study, of whom 30 had no cervical pain and 48 had CNP. The Neck Disability Index (NDI), cervical lordotic curvature, thoracic kyphotic curvature, thoracic sagittal range of motion (ROM), maximal inspiratory pressure (MIP), and maximal expiratory pressure (MEP) were measured and analyzed.
In males, thoracic sagittal ROMMEP-MIP and MEP showed a significant difference between the no cervical pain group and the CNP group. In females, thoracic kyphotic curvature, thoracic sagittal ROMMEP-MIP, MIP, and MEP were significantly different between the no cervical pain group and the CNP group. Thoracic kyphotic curvature was significantly correlated with MEP and MIP in all population groups, and significantly correlated with NDI in the female group. Thoracic sagittal ROMMEP-MIP had a significant linear relationship with NDI, MEP, and MIP in all population groups.
The thoracic mobility during forced respiration was reduced in patients with CNP and was correlated with respiratory strength. Changes in the biomechanics of the cervicothoracic spine and rib cage due to CNP may contribute to impairment of respiratory strength.
探讨慢性颈痛（CNP）患者与无颈部疼痛者在脊柱曲度、胸椎矢状面活动度和呼吸肌力方面的差异，并确定CNP患者呼吸肌力与胸椎活动度之间的相关性。
本研究最终纳入78名参与者，其中30人无颈部疼痛，48人患有CNP。测量并分析颈部功能障碍指数（NDI）、颈椎前凸曲度、胸椎后凸曲度、胸椎矢状面活动范围（ROM）、最大吸气压力（MIP）和最大呼气压力（MEP）。
在男性中，无颈部疼痛组和CNP组之间的胸椎矢状面ROM、MEP - MIP和MEP存在显著差异。在女性中，无颈部疼痛组和CNP组之间的胸椎后凸曲度、胸椎矢状面ROM、MEP - MIP、MIP和MEP存在显著差异。在所有人群组中，胸椎后凸曲度与MEP和MIP显著相关，在女性组中与NDI显著相关。在所有人群组中，胸椎矢状面ROM - MIP与NDI、MEP和MIP存在显著的线性关系。
CNP患者在用力呼吸时胸椎活动度降低，且与呼吸肌力相关。CNP导致的颈胸椎和胸廓生物力学变化可能导致呼吸肌力受损。
