Temporomandibular disorder (TMD) is considered multifactorial and is defined as a group of pain conditions characterized by functional stomatognathic system alterations, which may be affected by or related disrupted postural control.
Assess the immediate effect of nonspecific mandibular mobilization (NMM) on the postural control of subjects diagnosed or not with TMD.
A simple-blind, randomized, controlled clinical trial was performed involving 50 subjects of both genders assigned to two groups: the TMD group and the control group. TMD was diagnosed according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). A stabilometric assessment was performed by testing subjects in a quiet stance on a dual force platform under two visual conditions (eyes open and eyes closed). The Center of Pressure (CoP)-related variables analyzed were displacement, amplitude, speed of anterior-posterior (AP) and medial-lateral (ML) displacements and CoP sway area. The mean values of each variable were compared, considering the accepted significance value of p<0.05.
A significant difference between the pre- and post-NMM means could be observed in subjects diagnosed with TMD under the closed-eyes visual condition. There was a statistically significant difference in the CoP sway area (p<0.03) in the ML displacement COPML (p<0.006) and ML amplitude COPML (p<0.01) and in the variable speed in the AP COPAP (p<0.03) and ML COPML (p<0.03) directions, simultaneously.
These results indicate that nonspecific temporomandibular joint mobilization contributes to the immediate improvement of postural control in patients with TMD.
颞下颌关节紊乱（TMD）被认为是多因素的，并被定义为一组以咀嚼肌系统功能改变为特征的疼痛病症，这些改变可能受到或与姿势控制障碍有关。
评估非特异性下颌关节松动术（NMM）对 TMD 诊断或未诊断患者的姿势控制的即刻影响。
进行了一项简单盲法、随机、对照临床试验，涉及 50 名男女受试者，分为两组：TMD 组和对照组。根据颞下颌关节紊乱研究诊断标准（RDC/TMD）诊断 TMD。通过在双力平台上的安静姿势下在两种视觉条件（睁眼和闭眼）下对受试者进行平衡评估来进行。分析的与中心压力（CoP）相关的变量包括位移、幅度、前后（AP）和内外（ML）位移的速度以及 CoP 摆动面积。考虑到可接受的 p<0.05 显著性水平，比较了每个变量的平均值。
在闭眼视觉条件下，诊断为 TMD 的受试者在接受 NMM 前后的平均值之间可以观察到显著差异。在 CoP 摆动面积（p<0.03）、ML 位移 CoPML（p<0.006）和 ML 幅度 CoPML（p<0.01）以及 AP CoPAP（p<0.03）和 ML COPML（p<0.03）方向的速度变量中，同时存在统计学显著差异。
这些结果表明，非特异性颞下颌关节松动术有助于 TMD 患者即刻改善姿势控制。
