Abstract：
BACKGROUND: Migraine may be accompanied by several cervical musculoskeletal dysfunctions, for example an altered performance on the Craniocervical Flexion Test (CCFT). However, CCFT measurement properties are still unclear in patients with migraine.
OBJECTIVE: To determine intra- and inter-examiner reliability, construct validity, standard measurement error (SEM), and minimal detectable change (MDC) of the CCFT in patients with migraine.
METHODS: Women diagnosed with migraine were considered eligible for this study. Participants were assessed by two examiners for the inter-examiner reliability, and with 7-10 days interval for the intra-examiner reliability. Construct validity was assessed considering headache and neck pain frequency and intensity, and self-reported questionnaires, including the Headache Impact Test - 6 items (HIT-6), the 12-item Allodynia Symptom Checklist/Brazil (ASC-12), and the Neck Disability Index (NDI). In addition, participants performed cervical endurance and maximal voluntary isometric contraction of the cervical flexors.
RESULTS: A total of 103 women with migraine were recruited. The intra-examiner reliability was rated as good (ICC= 0.81, 95% CI: 0.73, 0.87), while the inter-examiner reliability was rated as moderate (ICC= 0.55, 95% CI: 0.40, 0.67). The intra and inter-examiner SEM were 1.31 and 1.36 mmHg respectively, and MDC were 3.63 and 3.77 mmHg. The HIT-6 and the cervical endurance flexion test were associated with the CCFT in a multiple linear regression model (p = 0.004, R = 0.35).
CONCLUSIONS: The CCFT presents adequate intra- and inter-examiner reliability. Better performance on the CCFT test was associated with better HIT-6 scores and greater cervical endurance time, which was not influenced by the presence of neck pain.

摘要：
背景：偏头痛可能伴有几种颈部肌肉骨骼功能障碍，例如颅颈屈曲测试（CCFT）的性能改变。然而,偏头痛患者的CCFT测量特性仍不清楚。
目的：为了确定考试中和考试间的可靠性，构造效度，标准测量误差(SEM)，偏头痛患者CCFT的最小可检测变化（MDC）。
方法：被诊断为偏头痛的女性被认为符合本研究的条件。参与者由两名考官评估考试者之间的可靠性，并以7-10天的间隔进行检查。考虑头痛和颈部疼痛的频率和强度，评估结构效度。和自我报告的问卷，包括头痛冲击测试-6项（HIT-6），12项异常性疼痛症状清单/巴西（ASC-12），颈部残疾指数（NDI）。此外,参与者进行了颈椎耐力和最大程度的颈椎屈肌自愿性等距收缩.
结果：共招募了103名偏头痛患者。考内信度被评为良好(ICC=0.81，95%CI：0.73，0.87)，而检查者之间的可靠性被评为中等（ICC=0.55，95％CI：0.40，0.67）。内部和之间的SEM分别为1.31和1.36mmHg，MDC分别为3.63和3.77mmHg。在多元线性回归模型中，HIT-6和颈椎耐力屈曲测试与CCFT相关（p=0.004，R=0.35）。
结论：CCFT具有足够的检查内和检查间可靠性。更好的CCFT测试表现与更好的HIT-6评分和更大的颈椎耐力时间相关。不受颈部疼痛的影响。
