Functional change in the pattern of swallowing through the performance of orofacial exercises

Abstract

Purpose: The objective was to determine if there was functional improvement of swallowing pattern in subjects identified with risk of oropharyngeal dysphagia after four weeks of specific oropharyngeal exercises. These exercises have pre-determined intensity and duration. Methods: It is a longitudinal study of functional effect, determined by initial and final comparative measures. Participants were adults and elderly, selected in a period of 24 months. A total of 68 participants were included. All subjects had a clinical evaluation of swallowing, and an initial measure in a functional scale. The individuals were split into two groups, according to the initial levelling of ASHA NOMS scale. In Group 1 (G1) - ASHA NOMS, initial of levels 1 and 2; Group 2 (G2) - ASHA NOMS, initial of levels 3, 4 and 5. All subjects executed an exercise protocol performed for four weeks. The protocol includes sessions with a speech therapist, and continuity of activities in home environment. Finally, new measurement of swallowing performance was held. Results: For G2 group there was statistically significant improvement. For G1, the relation was insignificant, despite the intense change in ASHA NOMS scale, however, in this group there was a reduced number of individuals due to the profile severity. Conclusion: The program was effective because after four exercise sessions, there was significant improvement in swallowing pattern, demonstrated by functional scale.
