This study investigated the deep upper cervical muscles echogenicity in cervicogenic headache (CGH) patients.
The echogenicity of longus capitis (LCAP), rectus capitis posterior major (RCPM), and obliquus capitis superior (OCS) muscles was measured by ultrasonography and analyzed by Image J software in 17 CGH patients matched with 17 healthy subjects.
The echogenicity of all muscles in the CGH group was higher than that in healthy subjects. The echogenicity of the LCAP muscle on the right side was significantly different between the CGH and healthy subjects (< 0.05), but there was no difference in the echogenicity of RCPM and OCS muscles between the groups (> 0.05). Additionally, the echogenicity differences did not match with the pain side in CGH patients (> 0.05).
Only the deep anterior muscle (LCAP) echogenicity affected by CGH and fatty infiltration occurred in this muscle. Hence, anterior muscle dysfunction is important in CGH diagnosis and treatment.
本研究探讨颈源性头痛（CGH）患者深部颈上肌群的超声回声特点。
通过超声检查测量 17 例 CGH 患者和 17 例健康对照者的头长肌（LCAP）、头后大直肌（RCPM）和头夹肌（OCS）的回声，并使用 Image J 软件进行分析。
CGH 组所有肌肉的回声均高于健康对照组。CGH 组右侧 LCAP 肌肉的回声明显不同于健康对照组（<0.05），但 RCPM 和 OCS 肌肉的回声在两组之间无差异（>0.05）。此外，CGH 患者的回声差异与疼痛侧不匹配（>0.05）。
只有 CGH 受累的深部前肌（LCAP）出现回声改变和脂肪浸润，因此，前肌功能障碍在 CGH 的诊断和治疗中很重要。
