A basic study of the facial muscle function applied to the physical and psychological rehabilitation

口周种族肌在日常生活中起着重要的作用，如表达、咀嚼、吞咽、发音、交流等。因此，面部肌肉功能的改善或恢复可以改善口面部的形态和功能，改善精神状态。2002年，为了测定不同口腔活动时颊肌和口轮匝肌的肌电活动，对6名牙列正常的健康受试者进行了双侧颊肌、口轮匝肌、咬肌和二腹肌的肌电活动记录。咀嚼口香糖时，颊肌和口轮匝肌均有节律性爆裂。然而，在没有食物的情况下，在开合动作、敲击和咬合时，没有观察到颊肌的肌电活动。这些结果表明，日常生活中面部肌肉的有效激活可以改善面部肌肉的功能。此外，在2003年，我们的目标是开发一种有效的食物，用于口腔周围面部肌肉的肌肉功能治疗。实验结果表明，口轮匝肌的活性依赖于口轮匝肌的质地和食量，而不是口轮匝肌的质地。

The perioral racial muscles are deeply concerned with the important function for our daily life, such as expression, mastication, deglutituion, pronunciation and communication. Thus, the improvement or the recovery of the function of facial muscles leads to improve the shape and function in the oro-facial region and mental condition. In 2002, to determine the EMG activities of the buccinator muscle and the orbicularis oris muscle during various oral activities, EMG activities of m.buccinator, m.orhicularis oris, m.masseter and m.digastric were recorded bilaterally in six healthy subjects with normal dentition. Both buccinator and orbicularis oris rhythmically burst during jaw opening of gum chewing. However, without food, no EMG activities of buccinator were observed in jaw open-close movement, tapping or clenching. These results suggested that the effective activation or facial muscles in daily life improve the function of facial muscles. In 2003, additionally, we aimed to develop an effective food for muscle function therapy using perioral facial muscles. The results of this experiment demonstrated that the activities of buccinator muscle are dependent on the texture and the amount of test food and that the activities of orbicularis oris muscle are dependent on the amount of test food but the texture.
