In addition to the diagnosis of dysphagia, the patient should specifically present deficit in the hyoid elevation during swallowing, showing weakness in the suprahyoid muscles during this function.
In all of the subjects in this study were measure the amplitude and time of the electrical activity of suprahyoid muscles during swallowing, before the first therapy session.
The traditional speech therapy included the realization of active myofunctional exercises that promote contraction of suprahyoid muscles, associating them with saliva or food swallowing, in a safe consistency to patient.
The use of NMES in the experimental group included the application of electric stimulus through two adhesive electrodes 3 cm in diameter applied on clean skin in suprahyoid muscles area.
This study investigated the effect of electrical stimulation Neuromuscular (NMES) in the contraction of suprahyoid muscles during swallowing in post-stroke patients with oropharyngeal dysphagia.
According to the data found in this research is not possible to affirm that the use of NMES associated with active exercises or the realization only of the latter, was effective in promoting increased contraction of suprahyoid muscles.
The same method of measurement was used in another study  that evaluated sixty healthy individuals with sEMGBiofeedback, aiming to check the electrical activity of suprahyoid muscles during swallowing function.
