Electromyographic (EMG) activity was recorded from the anterior, middle, and posterior regions of the temporalis muscle in ten subjects with normal occlusion of the teeth and with the mandible at rest and during exertion of increased biting force, using bipolar intramuscular electrodes. Results show that the posterior part of the temporalis muscle maintains the mandibular posture. Although there is no statistically significant difference in EMG recordings between the three divisions of the temporalis muscle during intercuspal biting, individual variations in EMG pattern exist. During exertion of increased biting force the EMG activity increases proportionally in all parts of the muscle. During retruded biting force the posterior temporalis predominates. The EMG activity of the temporalis muscle is correlated to the form and position of the mandible.
使用双极肌内电极，对10名牙齿咬合正常、下颌处于休息状态以及在增加咬合力时的受试者颞肌前、中、后区域的肌电图（EMG）活动进行了记录。结果表明，颞肌后部维持下颌姿势。虽然在牙尖交错咬合时颞肌三个分区的肌电图记录在统计学上没有显著差异，但肌电图模式存在个体差异。在增加咬合力时，肌肉各部分的肌电图活动成比例增加。在后退咬合力时，颞肌后部占主导。颞肌的肌电图活动与下颌的形态和位置相关。
