The relationship between the forward head posture and mechanosensitivity in subjects with a cervicogenic headache (CGH) remains uncertain. The aim of the study was to evaluate if there was a relationship between the tissue mechanosensitivity and cranio-cervical angle (CCA) that was moderated by pain intensity and/or disability in subjects with CGH. A convenience sample of 102 subjects was recruited. The CCA was measured with photographs, using a postural assessment software. The pain intensity was measured with a visual analogue scale (VAS), and the disability was measured with the Northwick Park Questionnaire. The pressure pain threshold (PPT) was measured at the spinous process of C2, the upper trapezius and splenius capitis muscles, and the median nerve. Simple moderation multiple regression analyses were constructed. There was a positive relationship between PPT at C2 and CCA, but a nonsignificant relationship for the PPT measured at the muscles and median nerve. The effect of PPT at C2 over CCA was moderated by pain intensity (R = 0.17; R change = 0.06; < 0.05) but not disability. The Johnson-Neyman analysis revealed a cut-off point for the statistical significance of 4.66 cm in VAS. There seems to be a positive relationship between PPT at C2 and CCA, which is positively moderated by pain intensity in subjects with CGH.
在患有颈源性头痛（CGH）的受试者中，头部前伸姿势与机械敏感性之间的关系仍不明确。本研究的目的是评估在患有CGH的受试者中，组织机械敏感性与颅颈角（CCA）之间是否存在一种由疼痛强度和/或功能障碍所调节的关系。招募了102名受试者作为便利样本。使用姿势评估软件通过照片测量CCA。使用视觉模拟量表（VAS）测量疼痛强度，使用诺斯威克公园问卷测量功能障碍。在C2棘突、上斜方肌和头夹肌以及正中神经处测量压力痛阈（PPT）。构建了简单调节多元回归分析。C2处的PPT与CCA之间存在正相关，但在肌肉和正中神经处测量的PPT之间无显著相关性。C2处的PPT对CCA的影响受疼痛强度调节（R = 0.17；R变化 = 0.06；<0.05），但不受功能障碍调节。约翰逊 - 内曼分析揭示了VAS中具有统计学意义的截断点为4.66厘米。在患有CGH的受试者中，C2处的PPT与CCA之间似乎存在正相关，且受疼痛强度正向调节。
