Abstract

Purpose: To evaluate the reproducibility and reliability of a novel electromyogram (EMG) device with a flexible sheet sensor for measuring muscle activity related to mastication and swallowing.

Methods: We developed a new EMG device made of elastic sheet electrodes to measure the masseter and digastric muscle activities for evaluating mastication and swallowing. To examine the measurement reproducibility of the new EMG device, masseter muscle activity was analyzed using the intraclass correlation coefficient (ICC). Further, we measured the maximum amplitude, duration, integrated value, and signal-to-noise ratio (SNR) using the new EMG device and conventional EMG devices and evaluated the reliability using ICC and Bland-Altman analysis.

Results: We confirmed high ICC (1,1) and ICC (2,1) scores (0.92 and 0.88, respectively) while measuring the reproducibility of the new EMG device. When compared to the active electrode EMG device, we found a high correlation for the maximum amplitude (0.90), duration (0.99), integrated values (0.90), and SNR (0.75), with no observation of significant fixed errors. Moreover, the regression coefficient was not significant for any of the evaluation items and no proportional error was observed. Compared with the passive electrode EMG device, the maximum amplitude and duration were highly correlated (0.73 and 0.89). In addition, the SNR exhibited a significant fixed error. In contrast, the regression coefficient was not significant for any of the evaluation items and no proportional error was observed.

Conclusions: Our results suggest that the new EMG device can be used to reliably and reproducibly evaluate muscle activity during mastication and swallowing.

使用新型肌电图（利用弹性片电极）评估下颌肌和掘起肌的活动。

目的：评估一种新型肌电图（EMG）装置的再现性和可靠性：我们开发了一种由弹性片状电极制成的新型肌电图设备，用于测量咀嚼和吞咽时的肌肉活动。为了检验新型肌电图装置的测量重现性，我们使用类内相关系数（ICC）分析了咀嚼肌的活动。此外，我们还使用新型肌电图设备和传统肌电图设备测量了最大振幅、持续时间、综合值和信噪比（SNR），并使用 ICC 和 Bland-Altman 分析评估了可靠性：在测量新型肌电图设备的可重复性时，我们确认了较高的 ICC (1,1) 和 ICC (2,1) 分数（分别为 0.92 和 0.88）。与有源电极肌电图设备相比，我们发现最大振幅（0.90）、持续时间（0.99）、综合值（0.90）和信噪比（0.75）具有很高的相关性，没有观察到明显的固定误差。此外，所有评估项目的回归系数均不显著，也未观察到比例误差。与被动电极肌电图设备相比，最大振幅和持续时间高度相关（0.73 和 0.89）。此外，信噪比显示出显著的固定误差。相比之下，回归系数在所有评估项目中都不显著，也没有观察到比例误差：我们的研究结果表明，新型肌电图设备可用于可靠、可重复地评估咀嚼和吞咽时的肌肉活动。

期刊介绍： Journal of Prosthodontic Research is published 4 times annually, in January, April, July, and October, under supervision by the Editorial Board of Japan Prosthodontic Society, which selects all materials submitted for publication. Journal of Prosthodontic Research originated as an official journal of Japan Prosthodontic Society. It has recently developed a long-range plan to become the most prestigious Asian journal of dental research regarding all aspects of oral and occlusal rehabilitation, fixed/removable prosthodontics, oral implantology and applied oral biology and physiology. The Journal will cover all diagnostic and clinical management aspects necessary to reestablish subjective and objective harmonious oral aesthetics and function. The most-targeted topics: 1) Clinical Epidemiology and Prosthodontics 2) Fixed/Removable Prosthodontics 3) Oral Implantology 4) Prosthodontics-Related Biosciences (Regenerative Medicine, Bone Biology, Mechanobiology, Microbiology/Immunology) 5) Oral Physiology and Biomechanics (Masticating and Swallowing Function, Parafunction, e.g., bruxism) 6) Orofacial Pain and Temporomandibular Disorders (TMDs) 7) Adhesive Dentistry / Dental Materials / Aesthetic Dentistry 8) Maxillofacial Prosthodontics and Dysphagia Rehabilitation 9) Digital Dentistry Prosthodontic treatment may become necessary as a result of developmental or acquired disturbances in the orofacial region, of orofacial trauma, or of a variety of dental and oral diseases and orofacial pain conditions. Reviews, Original articles, technical procedure and case reports can be submitted. Letters to the Editor commenting on papers or any aspect of Journal of Prosthodontic Research are welcomed.
