Abstract

|
sEMG(Surface electromyography) would have a potential to a diagnostic device with reliable, non-invasive, time-saving, inexpensive, and easy to use for swallowing disorder. Therefore, this study would review the sEMG evaluation method for dysphagia. Swallowing protocols were established with the swallowing of 3, 5, 10, 15, and 20 ml of water to measure the dysphagia in various swallowing loads and in four stages. Commonly, masseter, suprahyoid muscles, and infrahyoid muscles were investigated to observe swallowing movements. The primary sEMG outcome parameters were swallowing onset, pretrigger duration, swallowing duration, swallowing amplitude, and detecting abnormal involuntary action potential. Particularity, investigation in swallowing duration of sEMG is a simple and reliable method for screening and initial evaluation of dysphagia with noninvasive and radiation-free.
