Objective: The purpose of this study is to apply swallowing muscle strengthening exercises to chronic stroke patients with dysphagia and examine the effects of the exercises on the patients swallowing function and quality of life.
Method: Thirty-one patients with dysphagia were randomly selected and assigned to a chin tuck against resistance exercise group of 10 patients, and a jaw opening against resistance exercise group of 10 patients, a traditional swallowing exercise group of 11 patients. While the patients were receiving their training in 30 minute sessions, 5 times per week for 8 weeks, VDS (Videofluoroscopic Dysphagia Scale), MASA (Mann Assessment of Swallowing Ability), and PAS (Penetration Aspiration Scale) were used at 0, 4, and 8 weeks after the beginning of the experiment to assess the patients’ swallowing functions, and K-SWAL-QOL (Korean Swallowing Quality Of Life) tests were conducted to measure the quality of life of the patients with dysphagia. Repeated measure ANOVAs were conducted for intragroup comparisons of VDS, MASA, PAS, and K-SWAL-QOL before and after the training and one-way ANOVAs were conducted for intergroup comparison of changes before and after the training (SPSS 18.0 ver).
Results: All experimental CTAR and JOAR and TSE showed significant differences in VDS, MASA, and PAS K-SWQL-QOL after training ( p <.05). When the three groups were compared, no significant difference was shown in VDS and K-SWAL-QOL. MASA was shown to be significantly different between CTAR and TSE, and PAS was shown to be significantly different between JOAR and TSE ( p <.05).
Conclusion: The results show that CTAR and JOAR can improve swallowing functions and enhance satisfaction with the quality of life.
