Title: Magnetic resonance imaging study of the morphometry of cervical extensor muscles in chronic tension-type headache. Author(s): Fernández-de-Las-Peñas C; Bueno A; Ferrando J; Elliott JM; Cuadrado ML; Pareja JA Author's Address: Department of Physical Therapy, Occupational Therapy, Physical Medicine and Rehabilitation of Universidad Rey Juan Carlos, Spain. cesarfdlp@yahoo.es Source: Cephalalgia: An International Journal Of Headache [Cephalalgia] 2007 Apr; Vol. 27 (4), pp. 355-62. Publication Type: Journal Article Language: English Journal Information: Country of Publication: England NLM ID: 8200710 Publication Model: Print Cited Medium: Print ISSN: 0333-1024 (Print) Subsets: In Process; MEDLINE Entry Date(s): Date Created: 20070322 Update Code: 20070430 PMID: 17376113 Persistent link to this record:http://search.ebscohost.com/logi ... amp;site=ehost-live Database: MEDLINE Abstract: This study analyses the differences in the relative cross-sectional area (rCSA) of several cervical extensor muscles, assessed by magnetic resonance imaging (MRI), between patients with chronic tension-type headache (CTTH) and healthy controls. 该研究运用MRI评价慢性紧张型头痛患者和健康对照者颈部伸肌的横截面积的差异。 MRI of the cervical spine was performed on 15 CTTH females and 15 matched controls. 15名女性慢性紧张型头痛患者和15名女性对照者进行了颈椎MRI检查。 The rCSA values for the rectus capitis posterior minor (RCPmin), rectus capitis posterior major (RCPmaj), semispinalis capitis and splenius capitis muscles were measured from axial T1-weighted images using axial MR slices aligned parallel to the C2/3 intervertebral disc. 在T1加权相颈2/3椎间盘水平切面测量头后小直肌、头后大直肌、半棘肌、头夹肌的横截面积。 A headache diary was kept for 4 weeks in order to substantiate the diagnosis and record the pain history. 为期4周的头痛日记以明确诊断和记录头痛病史。 CTTH patients showed reduced rCSA for both RCPmin and RCPmaj muscles (P < 0.01), but not for semispinalis and splenius capitis muscles, compared with controls. 与对照组比较，慢性紧张型头痛患者头后小直肌和头后大直肌横截面积减小，但半棘肌和头夹肌未显示差异。 Headache intensity, duration or frequency and rCSA in both RCPmin and RCPmaj muscles were negatively correlated (P < 0.05): the greater the headache intensity, duration or frequency, the smaller the rCSA in the RCPmin and RCPmaj muscles. 头痛的程度、持续时间和 频率 都与头后小直肌和头后大直肌横截面积呈负相关。 CTTH patients demonstrate muscle atrophy of the rectus capitis posterior muscles. 慢性紧张型头痛患者存在头后直肌萎缩。 Whether this selective muscle atrophy is a primary or secondary phenomenon remains unclear. 这种选择性的肌肉萎缩是原发性或继发性现象仍不清楚。 In any case, muscle atrophy could possibly account for a reduction of proprioceptive output from these muscles, and thus contribute to the perpetuation of pain. 无论如何，肌肉萎缩可能说明了来自这些部位本体感受器输出的减少，导致了持续性的疼痛。 |
