口腔练习，包括舌头、嘴唇和下巴的运动，在临床实践中通常被用作改善吞咽困难患者的口腔和咽部吞咽的训练。这些康复运动被认为在不同程度上影响外周和中枢神经系统。然而，很少有研究考察健康受试者在进行用于吞咽困难康复的口头练习时的大脑活动。目前的研究试图使用功能磁共振成像(FMRI)来测量健康受试者在口头锻炼过程中的大脑激活。舌头和嘴唇练习任务被选为舌头和嘴唇伸展、舌头突出、舌头侧移和口中滚球。这些任务由8名健康受试者完成，并将fMRI数据提交给联合分析。结果证实，在所有任务中，头部运动在x、y和z坐标上平移1.0 mm，旋转1.0a度。在所有四个口语练习中，我们都发现了几个明显的大脑活动增加的区域。在舌头和嘴唇练习中，常见的激活区域包括中央前回和小脑。与其他三种口语练习相比，滚球时大脑的激活更广泛、更强烈。
Oral exercises, including tongue, lip, and jaw movements, are commonly used in clinical practice as training to improve oral and pharyngeal swallowing in dysphagia patients. These rehabilitation exercises are believed to affect the peripheral and central nervous system at various levels. However, few studies have examined healthy subjects' brain activity while performing oral exercises used in dysphagia rehabilitation. The current study sought to measure brain activation during oral exercises in healthy subjects using functional magnetic resonance imaging (fMRI). Lip-pursing and lip-stretching, tongue protrusion, lateral tongue movement, and oral ball-rolling were selected as tongue and lip exercise tasks. The tasks were performed by eight healthy subjects, and the fMRI data were submitted to conjunction analyses. The results confirmed that head movements during all tasks exhibited translation of < 1.0 mm and rotation of < 1.0A degrees in x, y, and z coordinates. We found several clear regions of increased brain activity during all four oral exercises. Commonly activated regions during tongue and lip exercises included the precentral gyrus and cerebellum. Brain activation during ball-rolling was more extensive and stronger compared to the other three oral exercises.
