Description

<p>Mori H, Izumi S, Kagaya H, Oyama H, Abe G, Yashima K, Takagi T. Evaluation of the myoelectric potential of the infrahyoid muscles as a means of detecting muscle activity of the suprahyoid muscles. Jpn J Compr Rehabil Sci 2020; 11: 52-58. </p><p>Objective: To investigate the use of the myoelectric potential of the infrahyoid muscles as a synchronizing signal for the contraction of the suprahyoid muscles during swallowing. </p><p>Methods: The myoelectric potentials of the anterior belly of the digastric muscle and the sternohyoid muscle of 10 healthy adults during swallowing were measured, and the activity of each muscle was analyzed. Additionally, the real-time process of muscle activity detection was simulated using the measured waveform of the myoelectric potentials. </p><p>Results: The ratio of the “elapsed time from the activity of the anterior belly of the digastric muscle to the activity of the sternohyoid muscle” to the “time of activity of the anterior belly of the digastric muscle” was 22.5 ± 19.6%. The sternohyoid muscle activity started in the early period of activity of the digastric muscle. In the simulation, differential processing enabled detection of the activity of the sternohyoid muscle in 49 of 50 trials within the activation time of the anterior belly of the digastric muscle. </p><p>Conclusion: The myoelectric potential of the sternohyoid muscle can be used as a synchronization signal for the contraction of the anterior belly of the digastric muscle during swallowing.</p>
