The study evaluated the extent to which the source, intensity, and duration of temporomandibular disorder (TMD) pain are predictors of limitations in jaw function.
The sample included 166 subjects (12-69 years) who self-administered the Jaw Function Limitation Scale (JFLS) and underwent clinical examinations.
In univariate correlations, global limitation (long-form JFLS) as well as mastication, mobility, and communication had the highest correlation with headache attributed to TMD (r = 0.362-0.415; < 0.001). Correlation was higher for pain intensity than chronicity. In multiple regression analysis, significant predictors of jaw limitations (long-form JFLS) were only headache and increasing age ( < 0.001), when controlling for demographic variables, the characteristics of pain, source of pain, and presence of intraarticular disorders.
Limitation in jaw function is influenced more by pain than by the intracapsular condition and even more so by pain intensity than chronicity.
本研究评估了颞下颌关节紊乱（TMD）疼痛的来源、强度和持续时间在多大程度上可预测下颌功能受限。
该样本包括 166 名受试者（12-69 岁），他们自行填写了下颌功能受限量表（JFLS）并接受了临床检查。
在单变量相关分析中，整体受限（长式 JFLS）以及咀嚼、活动度和言语功能与 TMD 所致头痛的相关性最高（r = 0.362-0.415；<0.001）。疼痛强度与慢性疼痛相比，与相关性更高。在多元回归分析中，当控制人口统计学变量、疼痛特征、疼痛来源和关节内疾病的存在时，下颌功能受限（长式 JFLS）的显著预测因子仅为头痛和年龄增长（<0.001）。
下颌功能受限受疼痛影响甚于关节内状况，且疼痛强度比慢性疼痛的影响更大。
