Evidence suggests that cervicogenic headache is associated with increasing age. Cervical musculoskeletal impairments are common features in individuals with cervicogenic headache. There is some suggestion that the structure (size and fatty infiltration) of neck muscle may factor in or contribute to these impairments.
To investigate relative cross sectional areas (rCSAs) and fatty infiltrate in the cervical muscles in elders with cervicogenic headache compared to controls.
Fourteen elder women with cervicogenic headache and 14 controls participated in the study. The rCSAs and fat infiltration were measured for the rectus capitis posterior major, rectus capitis posterior minor, multifidus, semispinalis capitis, splenius capitis, longus capitis/colli, and sternocleidomastoid.
Elder women with cervicogenic headache had significantly reduced rCSAs of the rectus capitis posterior major and multifidus muscles compared to controls (p < 0.05). Larger amounts of fat infiltrates were also observed in the rectus capitis posterior major and minor and splenius capitis muscles in the cervicogenic headache group (p < 0.05). There were no changes in the size and fat infiltrate in the cervical flexor muscles (p > 0.05).
The study demonstrated muscle atrophy with increased fatty infiltration in regionally select muscles of the upper and segmental cervical spine in older women with cervicogenic headache. While such changes and their influence on clinical symptoms are unknown, they may have management implications. Future research investigations are required to determine whether such alterations could be modified with specific exercise and modifications to daily living to positively influence clinical symptoms.
有证据表明，颈源性头痛与年龄增长有关。颈肌骨骼功能障碍是颈源性头痛患者的常见特征。有一些证据表明，颈部肌肉的结构（大小和脂肪浸润）可能是这些功能障碍的因素之一或促成因素。
研究与对照组相比，颈源性头痛的老年患者颈部肌肉的相对横截面积（rCSA）和脂肪浸润情况。
14 名患有颈源性头痛的老年女性和 14 名对照者参与了这项研究。对枕骨下直肌、枕骨下斜肌、多裂肌、头半棘肌、头夹肌、头最长肌/颈肌和胸锁乳突肌的 rCSA 和脂肪浸润进行了测量。
与对照组相比，患有颈源性头痛的老年女性枕骨下直肌和多裂肌的 rCSA 明显减小（p<0.05）。颈源性头痛组的枕骨下直肌和斜肌以及头夹肌的脂肪浸润量也更大（p<0.05）。颈椎屈肌的大小和脂肪浸润没有变化（p>0.05）。
该研究表明，颈源性头痛的老年女性存在区域性选择的上颈段和节段性颈椎肌肉萎缩伴脂肪浸润增加。虽然这些变化及其对临床症状的影响尚不清楚，但它们可能具有管理意义。需要进一步的研究来确定这些改变是否可以通过特定的运动和日常生活方式的改变来改善，从而对临床症状产生积极影响。
