[Purpose] Measurement of the diadochokinetic rate can provide useful information on swallowing rehabilitation in the oral phase by elucidating the speed and regularity of movement of muscles related to the lips, tongue, and chin. This study investigated the effect of a three-week period of orofacial myofunctional exercise on the improvement of cheek, tongue, and lip muscle strength and diadochokinetic rate in dysphagia patients. [Subjects and Methods] This study employed a pretest-posttest control group design. Both orofacial myofunctional exercise and the temperature-tactile stimulation technique were applied to the experimental group (n=23), while only the temperature-tactile stimulation technique was applied to the control group (n=25). [Results] Tongue elevation, tongue protrusion, cheek compression, lip compression, and alternating motion rate were more significantly improved in the experimental group than in the control group. [Conclusion] Orofacial myofunctional exercise is effective in the rehabilitation of swallowing function in the oral phase in dysphagia patients by improving orofacial muscle strength and response rate.
[目的] 测量轮替运动速率可通过阐明与嘴唇、舌头和下巴相关肌肉的运动速度和规律性，为口腔期吞咽康复提供有用信息。本研究调查了为期三周的口面部肌功能锻炼对吞咽困难患者脸颊、舌头和嘴唇肌肉力量改善以及轮替运动速率的影响。[对象与方法] 本研究采用前后测对照组设计。实验组（n = 23）同时进行口面部肌功能锻炼和温度触觉刺激技术，而对照组（n = 25）仅采用温度触觉刺激技术。[结果] 实验组的舌上抬、舌前伸、脸颊挤压、嘴唇挤压和交替运动速率比对照组有更显著改善。[结论] 口面部肌功能锻炼通过提高口面部肌肉力量和反应速率，对吞咽困难患者口腔期吞咽功能的康复有效。
