To assess the consistency of intentional behavioral performance as an index of whether individuals understood the meanings of the behavioral terms of the Oral Behaviors Checklist, which is a self-report scale for identifying and quantifying the frequency of jaw overuse behaviors.
Surface electromyography was used to measure bilaterally the activity of the masseter, temporalis, and suprahyoid muscles (for assessment of oral behaviors) and the biceps muscles (reference task of biceps curl) in 27 temporomandibular disorder (TMD) cases and 27 controls. Subjects were asked to perform (1) biceps curls to lift 5 weights, with explanation, and (2) 10 oral behaviors (e.g., "clench", "yawn") without explanation.
Biceps-curl performance resulted in assignments of excellent or very good for linearity-reliability based on inspection and correlation. Test-retest reliability of the 10 performed oral behaviors generally ranged from 0.6 to 0.98 for all 3 muscle groups, and many tasks had reliability coefficients comparable to those for the biceps curl. Across tasks, elevator muscle reliability of cases was 0.87, compared to 0.75 for controls; group values for opening muscles were similar.
Individual subjects performed each task at a high level of consistency. Performance was not appreciably altered by being a TMD case versus a control and was not significantly different from the performance level of a reference task, indicating that each individual understood well the meaning of each oral behavior-related word.
评估作为一种指标的故意行为表现的一致性，以此判断个体是否理解《口腔行为检查表》中行为术语的含义，该检查表是一种用于识别和量化下颌过度使用行为频率的自我报告量表。
采用表面肌电图双侧测量27例颞下颌关节紊乱病（TMD）患者和27名对照者的咬肌、颞肌和舌骨上肌群（用于评估口腔行为）以及肱二头肌（肱二头肌弯举的参照任务）的活动。要求受试者进行（1）在有解释的情况下进行肱二头肌弯举以举起5个重物，以及（2）在无解释的情况下进行10种口腔行为（如“紧咬”“打哈欠”）。
基于检查和相关性，肱二头肌弯举表现的线性可靠性评定为优秀或非常好。所执行的10种口腔行为在所有3个肌肉组中的重测信度一般在0.6至0.98之间，许多任务的信度系数与肱二头肌弯举的相当。在各项任务中，病例组的升肌信度为0.87，对照组为0.75；开口肌的组间值相似。
个体受试者在执行每项任务时具有高度的一致性。作为TMD患者还是对照者，表现并未明显改变，且与参照任务的表现水平无显著差异，这表明每个个体都很好地理解了每个与口腔行为相关词汇的含义。
