- Acoustic and Temporal Analysis of swallowing sounds: use of electronic stethoscope on cervical auscultationPublication . Pereira, Nelson; Faria, Paula; Santos, Ricardo; Araújo, André; Esperança, Joana; Pinheiro De Sousa, Andreia SofiaSwallowing is a physiologic function consisting in the propulsion of the bolus into the stomach, with effective respiratory protection. Clinical intervention of Speech and Language Therapists requires improved and reliable methods of swallowing evaluation. Cervical Auscultation (CA) is especially appreciated as a noninvasive method. However, conventional stethoscopes do not provide quantitative measures to complement the perceptive auditory analysis of the swallowing sounds
- Masseter’s electromyographic assessment in diferent consistencies food swallowingPublication . Esperança, Joana; Araújo, André; Santos, Ricardo; Faria, Paula; Pinheiro De Sousa, Andreia Sofia; Pereira, NelsonOrofacial Miology is a clinical and research field of interest for Speech and Language Pathology. Surface Electromyography (SEMG) has been used as a complementary diagnostic method to develop normative data and characterization of different oral motor dysfunctions, including swallowing disorders. One application of this method occurs in monitoring the electrical activity of the muscles involved in swallowing However, there is a need to standardize the procedures for collecting and analyzing electromyographic study of swallowing.
