背景资料。大多数颞颌关节紊乱病(TMD)患者都有颈椎功能障碍。然而，这种颈椎功能障碍仅通过对颈椎的一般临床检查进行定性评估。这项研究的目的是确定与健康对照组相比，TMD患者在进行颅颈屈曲测试(CCFT)时颈浅肌肉的活动是否增加。采用横断面研究方法。150人参与了这项研究：47人是健康的，54人患有肌源性TMD，49人患有混合性TMD。所有参与者都进行了CCFT检查。在CCFT期间收集所有参与者的胸锁乳突肌(SCM)和前斜角肌(AS)的肌电活动数据。重复测量的3向混合设计方差分析被用来评估在5个递增水平下进行CCFT时选定肌肉的肌电活动的差异。计算效应大小值以评估结果的临床相关性。尽管混合型和肌源性TMD患者在CCFT中SCM或AS肌肉的肌电活动与对照组相比无统计学差异，但TMD患者的颈浅肌肉活动有增加的趋势。本研究的结果适用于在所使用的方案下参与本研究的个体群体。它们可能适用于具有与本研究参与者相似特征的TMD患者。这些信息可能会让临床医生深入了解评估和可能的治疗TMD患者颈深屈肌的重要性。然而，未来的研究应该通过在TMD患者中进行随机对照试验来测试这种方案的有效性，以确定在这一人群中治疗这种类型的损害的真正价值。
Background. Most patients with temporomandibular disorders (TMD) have been shown to have cervical spine dysfunction. However, this cervical dysfunction has been evaluated only qualitatively through a general clinical examination of the cervical spine.Purpose. The purpose of this study was to determine whether patients with TMD had increased activity of the superficial cervical muscles when performing the craniocervical flexion test (CCFT) compared with a control group of individuals who were healthy.Design. A cross-sectional study was conducted.Methods. One hundred fifty individuals participated in this study: 47 were healthy, 54 had myogenous TMD, and 49 had mixed TMD. All participants performed the CCFT. Data for electromyographic activity of the sternocleidomastoid (SCM) and anterior scalene (AS) muscles were collected during the CCFT for all participants. A 3-way mixed-design analysis of variance for repeated measures was used to evaluate the differences in EMG activity for selected muscles while performing the CCFT under 5 incremental levels. Effect size values were calculated to evaluate the clinical relevance of the results.Results. Although there were no statistically significant differences in electromyographic activity in the SCM or AS muscles during the CCFT in patients with mixed and myogenous TMD compared with the control group, those with TMD tended to have increased activity of the superficial cervical muscles.Limitations. The results obtained in this research are applicable for the group of individuals who participated in this study under the protocols used. They could potentially be applied to people with TMD having characteristics similar to those of the participants of this study.Conclusion. This information may give clinicians insight into the importance of evaluation and possible treatment of the deep neck flexors in patients with TMD. However, future research should test the effectiveness of this type of program through a randomized controlled trial in people with TMD in order to determine the real value of treating this type of impairment in this population.
