Abstract：
OBJECTIVE: The objectives were to compare forward head posture (FHP) in natural and corrected head postures between patients with nonspecific neck pain (NSNP) and controls and to clarify the relationship between natural and corrected head posture angle differences and deep cervical flexor function. This study aimed to provide useful evidence for postural assessment and treatment in patients with NSNP.
METHODS: In this cross-sectional study, 19 patients with NSNP reporting a pain score of 3-7 for at least 3 months and 19 participants with no neck pain within the previous 12 months were recruited. To evaluate FHP, the cranial rotation and vertical angles were measured using lateral head and neck photographs. The craniocervical flexion test was used to evaluate deep cervical flexor activation and endurance. We evaluated the head and neck alignment in natural and corrected head postures and the relationship between the degree of change and deep cervical flexor function.
RESULTS: FHP in the natural head posture did not differ between groups. In the corrected head posture, FHP was significantly smaller in the NSNP group than in the control group. In the NSNP group, the cranial rotation and vertical angles were significantly different between the natural and corrected head postures, and the angle difference correlated significantly with deep cervical flexor function.
CONCLUSIONS: Patients with NSNP show hypercorrection in the corrected head posture, which may be correlated with deep cervical flexor dysfunction. Further investigation into the causal relationship between hypercorrection, deep neck flexor dysfunction, and neck pain is required.

摘要：
目的：目的是比较非特异性颈部疼痛（NSNP）患者和对照组的自然和矫正头位中的前头部姿势（FHP），并阐明自然和矫正头位角度差异与颈深屈肌功能之间的关系。本研究旨在为NSNP患者的体位评估和治疗提供有用的证据。
方法：在这项横断面研究中，招募了19名NSNP患者，其疼痛评分为3-7，持续至少3个月，以及19名在过去12个月内没有颈部疼痛的参与者。要评估FHP，使用侧头和颈部照片测量颅骨旋转和垂直角。颅颈屈屈试验用于评估深颈屈肌的激活和耐力。我们评估了自然和矫正头部姿势下的头颈部对准以及改变程度与颈深屈肌功能之间的关系。
结果：自然头部姿势的FHP在组间没有差异。在纠正的头部姿势中，NSNP组的FHP明显小于对照组。在NSNP组中，颅骨旋转和垂直角在自然和矫正的头部姿势之间有显著差异，角度差与颈深屈功能显著相关。
结论：患有NSNP的患者在矫正头部姿势时表现出过度矫正，这可能与颈深屈肌功能障碍有关。进一步调查超校正之间的因果关系，深颈屈肌功能障碍,颈部疼痛是必需的。
