Variability in swallowing electromyography (EMG) has been reported to occur due to individual differences, even in studies with appropriate control of factors affecting EMG such as food type, properties, and posture. The increased variability broadens the confidence intervals of measures obtained from EMG, such as time and amplitude, and makes it difficult to detect differences in muscle activity. This makes it impossible to detect slight changes in swallowing function at an early stage, which is required for clinical examination.

- - A new sensor sheet with multiple electromyography electrodes has been developed to measure muscle activities related to swallowing, aiming to help diagnose swallowing disorders.
- - In the study, 62 participants underwent tests to determine their swallowing capabilities, and muscle activity was monitored using the sensor sheet while swallowing various consistencies of food and liquids.
- - Results indicated significant differences in the duration of muscle activity for the infrahyoid muscles when swallowing certain items, demonstrating the sensor sheet's effectiveness in detecting swallowing disorders.
Background/purpose: We invented a sensor sheet with multiple electromyogram electrodes, which can be easily attached to the front of the neck, to evaluate surface electromyograms (sEMG) during swallowing function. In this paper, we evaluated sEMG in healthy volunteers and dysphagia patients using the sensor sheet and discussed its potential to evaluate swallowing function.
Materials And Methods: Ten healthy volunteers (age, 29.
Background: Quantitative assessment of swallowing function is necessary to prevent swallowing impairment due to ageing. Though surface electromyography (EMG) has been widely used to measure swallowing activity, the relationship between EMG results and swallowing function is unclear.
Objective: This study examined the relationship between the temporal characteristics of muscle activity and laryngeal elevation (LE) during swallowing.
