Temporomandibular disorders (TMD) has been suggested to be of multifactorial etiology. One factor that has been suggested is laxity of joint ligaments. The purpose of this study was to evaluate the relationship between generalized joint hypermobility and TMD. Thirty-eight asymptomatic volunteers and 62 symptomatic patients were included in this study. All asymptomatic volunteers did not have temporomandibular joint pain, limited jaw movement, joint sounds, or previous TMD treatment. All subjects had bilateral magnetic resonance imaging scans in the sagittal closed and opened and coronal closed positions. The Beighton test was used to score joint laxity with a laxity score of > or = 4 to define generalized joint laxity. The symptomatic group had an increase in joint laxity as compared to asymptomatic control subjects (odds ratio 4.0 [95% confidence interval = 1.38 to 10.95, P = .01]). There were no differences in laxity between male and female symptomatic subjects (P > .05). This study suggests a positive correlation between generalized joint laxity and TMD.
颞下颌关节紊乱病（TMD）被认为病因是多因素的。其中一个被提出的因素是关节韧带松弛。本研究的目的是评估全身关节过度活动与TMD之间的关系。本研究纳入了38名无症状志愿者和62名有症状的患者。所有无症状志愿者均无颞下颌关节疼痛、下颌运动受限、关节弹响或既往TMD治疗史。所有受试者均在矢状位闭口和开口以及冠状位闭口位置进行了双侧磁共振成像扫描。使用贝ighton试验对关节松弛度进行评分，松弛度评分≥4定义为全身关节松弛。与无症状对照组相比，有症状组的关节松弛度增加（优势比4.0 [95%置信区间=1.38至10.95，P = 0.01]）。有症状的男性和女性受试者之间的松弛度没有差异（P>0.05）。本研究表明全身关节松弛与TMD之间存在正相关。
