To study the frequency of cervical spine dysfunction (CCD) signs and symptoms in subjects with and without temporomandibular disorder (TMD) and to assess the craniocervical posture influence on TMD and CCD coexistence.
Participants were 71 women (19 to 35 years), assessed about TMD presence; 34 constituted the TMD group (G1) and 37 comprised the group without TMD (G2). The CCD was evaluated through the Craniocervical Dysfunction Index and the Cervical Mobility Index. Subjects were also questioned about cervical pain. Craniocervical posture was assessed by cephalometric analysis.
There was no difference in the craniocervical posture between groups. G2 presented more mild CCD frequency and less moderate and severe CCD frequency (p=0.01). G1 presented higher percentage of pain during movements (p=0.03) and pain during cervical muscles palpation (p=0.01) compared to G2. Most of the TMD patients (88.24%) related cervical pain with significant difference when compared to G2 (p=0.00).
Craniocervical posture assessment showed no difference between groups, suggesting that postural alterations could be more related to the CCD. Presence of TMD resulted in higher frequency of cervical pain symptom. Thus the coexistence of CCD and TMD signs and symptoms appear to be more related to the common innervations of the trigeminocervical complex and hyperalgesia of the TMD patients than to craniocervical posture deviations.
研究患有和未患有颞下颌关节紊乱病（TMD）的受试者中颈椎功能障碍（CCD）体征和症状的发生率，并评估颅颈姿势对TMD和CCD共存的影响。
参与者为71名女性（19至35岁），评估其是否存在TMD；34名构成TMD组（G1），37名组成无TMD组（G2）。通过颅颈功能障碍指数和颈椎活动指数评估CCD。还询问受试者有关颈部疼痛的情况。通过头影测量分析评估颅颈姿势。
两组之间的颅颈姿势无差异。G2组轻度CCD的发生率更高，中度和重度CCD的发生率更低（p = 0.01）。与G2组相比，G1组在运动时疼痛的百分比更高（p = 0.03），在颈部肌肉触诊时疼痛的百分比更高（p = 0.01）。与G2组相比，大多数TMD患者（88.24%）存在颈部疼痛，差异有统计学意义（p = 0.00）。
颅颈姿势评估显示两组之间无差异，表明姿势改变可能与CCD关系更大。TMD的存在导致颈部疼痛症状的发生率更高。因此，CCD和TMD体征和症状的共存似乎更多地与三叉神经颈复合体的共同神经支配以及TMD患者的痛觉过敏有关，而不是与颅颈姿势偏差有关。
