Abstract：
OBJECTIVE: This study aimed to investigate the potential of a newly developed small electrode to accurately record muscle activity during swallowing.
METHODS: This study included 31 healthy participants. The participants underwent swallowing trials with three types of material. The recordings involved the following conditions: 1) swallowing saliva, 2) swallowing 3 mL water, and 3) swallowing 5 mL water. Two types of electrodes, a conventional electrode (CE) and a newly developed small electrode (NE), were symmetrically positioned on the skin over the suprahyoid muscle group, starting from the center. From the surface electromyography data, the swallowing duration (s), peak amplitude, and rising time (duration from swallowing onset to peak amplitude: s) were measured. Additionally, the equivalence of characteristics of the waveform of muscle activities was calculated by using the variance in both the upper and lower confidence limits in duration and rising time.
RESULTS: No significant differences in baseline, swallowing duration or rising time between the CE and NE were observed for any swallowing material. The peak amplitude was significantly higher for the NE than for the CE for all swallowing materials. The CE and NE displayed no significant difference in the equivalence of characteristics of the waveform of muscle activities for any swallowing material.
CONCLUSIONS: The gold-plated small electrodes utilized in this study indicated the ability to record the same characteristics of muscle activity as conventional electrodes. Moreover, it was able to capture the muscle activity of each muscle group with improved sensitivity in a narrow area, such as under the submandibular region, with more precision than that of conventional electrodes.

摘要：
目的：本研究旨在研究新开发的小电极在吞咽过程中准确记录肌肉活动的潜力。
方法：本研究包括31名健康参与者。参与者接受了三种类型材料的吞咽试验。记录涉及以下条件：1）吞咽唾液，2）吞咽3mL水，和3)吞咽5mL水。两种类型的电极，传统电极（CE）和新开发的小电极（NE），对称地定位在舌骨上肌群的皮肤上，从中心开始。从表面肌电图数据来看，吞咽持续时间（S），峰值振幅,测量上升时间（从吞咽开始到峰值振幅的持续时间：s）。此外,通过使用持续时间和上升时间的置信上限和置信下限的方差来计算肌肉活动波形特征的等效性。
结果：基线无显著差异，观察到任何吞咽材料的吞咽持续时间或CE和NE之间的上升时间。对于所有吞咽材料，NE的峰值幅度明显高于CE。对于任何吞咽材料，CE和NE在肌肉活动波形特征的等效性方面没有显着差异。
结论：本研究中使用的镀金小电极表明能够记录与常规电极相同的肌肉活动特征。此外，它能够捕获每个肌肉群的肌肉活动，并在狭窄的区域提高灵敏度，比如颌下区域，比传统电极更精确。
