The deep neck flexor muscles (DNFs) stabilize the cervical spine and cervicogenic pain appears to adversely affect their endurance capacity. They are inaccessible to direct palpation, thereby making assessment difficult. However, the cranio-cervical flexion test (CCFT) provides an indirect method of assessing the endurance capacity of the DNFs. The purpose of the present study was to evaluate the intratester reliability of the CCFT in asymptomatic subjects.
The clinical protocol of the CCFT was measured on two occasions with 7 days between measurements. Prior to testing, participants were trained and compensation strategies were corrected. Nineteen asymptomatic participants (mean age 24.9 years; range 22-36) were recruited.
The test had excellent intratester reliability (intraclass correlation coefficient = 0.983; standard error of the mean = 8.94; smallest real difference = 24.7). A Bland and Altman's limits of agreement analysis confirmed the high reliability of the test.
The CCFT results demonstrated excellent intra-tester reliability in asymptomatic subjects, thus contributing to the normative data regarding the test.
颈深部屈肌（DNFs）可稳定颈椎，而颈源性疼痛似乎会对其耐力产生不利影响。这些肌肉无法直接触诊，因此评估困难。然而，颅颈屈曲试验（CCFT）提供了一种间接评估DNFs耐力的方法。本研究的目的是评估CCFT在无症状受试者中的测试者内可靠性。
CCFT的临床方案在两次测量中进行，测量间隔为7天。在测试前，对参与者进行培训并纠正补偿策略。招募了19名无症状参与者（平均年龄24.9岁；范围22 - 36岁）。
该测试具有出色的测试者内可靠性（组内相关系数 = 0.983；平均标准误差 = 8.94；最小真实差异 = 24.7）。Bland和Altman一致性界限分析证实了该测试的高可靠性。
CCFT结果在无症状受试者中显示出出色的测试者内可靠性，从而为该测试的规范数据做出了贡献。
