Objective : The purpose of this study was to investigate the educational status, knowledge, awareness, and readiness for dysphagia therapy among university occupational therapy students. Methods : One hundred and five online questionnaires completed by senior-year students at an occupational therapy university were analyzed. The questionnaire assessed the educational status, knowledge, awareness, and readiness for dysphagia therapy. Descriptive statistics and differences between those with and without practical experience were analyzed. The relationships among educational status, knowledge, and readiness were analyzed. Results : Independent opening of the dysphagia therapy class (69.5%) and experience in dysphagia practice were high (79.0%). Dysphagia education and knowledge in university and practice were moderate and item scores were higher for university education. Knowledge of adult dysphagia therapy was higher than that of pediatric dysphagia therapy. Scores on awareness, knowledge, and readiness for dysphagia therapy were significantly higher among students with practical experience. Conclusion : Education and knowledge of dysphagia therapy were moderate. Knowledge and readiness in adults are higher than in children. Systematic dysphagia therapy education in university and associated practices are needed to enhance the specialty of dysphagia therapy.

Purpose: The current study seeks to identify the effect of neck muscle strengthening exercise using proprioceptive neuromuscular facilitation (PNF) on the swallowing ability of patients diagnosed with dysphagia due to stroke. Methods: As a single case study, the current research conducted neck muscle strengthening exercise using PNF on the patient with dysphagia for 40 minutes, four times per week for a six-week period. At the same time, typical rehabilitation therapy for dysphagia was provided. This type of therapy included food-swallowing and the relation of the muscles surrounding the neck. The functional dysphagia scale and the penetration-aspiration scale were used to assess swallowing ability. Results: After the therapy, the functional dysphagia scale and the penetration-aspiration scale decreased by 18 points and 3 points, respectively, which proves the effectiveness of this type of therapy for dysphagia. Conclusion: The results of the current study indicate that neck muscle strengthening exercise using PNF reduces penetration-aspiration in patients with dysphagia, and that PNF can be clinically utilized to improve the swallowing ability of dysphagic patients.

Background: Recently, a new home-based dysphagia rehabilitation method using information and communications technology (ICT) has been reported, but clinical evidence is still lacking. Objectives: To investigate the effects of home-based dysphagia rehabilitation using ICT on tongue muscle strength and volume in patients with developed dysphagia after stroke. Design: Randomized controlled trial design. Methods: Twenty patients who developed dysphagia after stroke were enrolled. The experimental group received dysphagia rehabilitation in the form of ICT-based home care. In contrast, the control group received traditional rehabilitation based on swallowing under the supervision of occupational therapists. All interventions were conducted five times a week for four weeks. Results: Both groups showed statistically significant increases in tongue muscle strength and volume after the intervention (P<.05, both). However, there were no significant differences in tongue strength or volume between the two groups after the intervention (P>.05, both). Conclusion: Home-based dysphagia rehabilitation using ICT showed effects similar to those of conventional swallowing rehabilitation in patients who developed dysphagia after stroke. These findings suggest that dysphagia rehabilitation can be conducted at home without the help of a therapist.

Objective : This study aimed to investigate the awareness and experience of community-based dysphagia therapy and related education in community-dwelling older adults. Methods : A total of 89 older adults were recruited from a public health center in Gyeonggi-do. Awareness, experience, and related education regarding community-based dysphagia therapy were analyzed using descriptive statistics. Results : We analyzed 89 questionnaires. Awareness, treatment experience, and education regarding dysphagia were low; however, the importance and intention to participate were high. Respondents wanted education about proper chewing and safe swallowing, oral health, oral motor exercise, and participation in community-based dysphagia programs in public health centers. The reason for the lack of experience in dysphagia education and therapy is insufficient information and opportunities. The respondents had a good understanding of dysphagia symptoms. Conclusion : Dysphagia therapy maintains swallowing and eating functions as a life-long Activity of Daily Living, and is a very important area in community rehabilitation. Based on the results of this survey, the necessity and importance of community-based dysphagia were identified. It is time to provide correct information and develop a systematic education program for community-based dysphagia therapy. Occupational therapists need to play an active role in improving quality of life by early detection and providing proper intervention.

Background: Recently, a new method of dysphagia rehabilitation using Kinesio taping (KT) has been attempted and demonstrated an immediate increase in the activation of the suprahyoid muscle during swallowing in healthy adults. Objectives: To investigate the effect of dysphagia rehabilitation using KT on the thickness change of the suprahyoid muscle in patients with dysphagia after stroke. Design: Two-group pre-post design. Methods: In this study, 20 patients with dysphagia after stroke were enrolled and assigned to the experimental and control groups. The experimental group applied KT to the front of the neck and repeatedly swallowed against the tension of the tape. On the other hand, the control group performed repeated swallowing without applying KT. Patients in both groups had swallowed 50 times a day/5 times a week for 4 weeks. For evaluation, the volume of the geniohyoid, mylohyoid, and digastric muscle was measured before and after the intervention using portable ultrasound equipment. Results: As a result of comparing the two groups after the intervention, the experimental group showed more volume increase in mylohyoid (P<.05) and digastric muscle (P<.05) than the control group. Conclusion: This study proved that suprahyoid muscle resistance exercise using KT is effective in increasing the volume of the suprahyoid muscle.

Background: Patients with dysphagia after stroke are treated with neuromuscular electrical stimulation (NMES), but its effect on masseter muscle thickness and bite force in the oral phase is not well known. Objectives: To investigated the effect of NMES on masseter muscle thickness and occlusal force in patients with dysphagia after stroke. Design: Two group, pre-post design. Methods: In this study, 25 patients with dysphagia after stroke were recruited and allocated to either the experimental or the control groups. Patients in the experimental group were treated with NMES to the masseter muscle at the motor level for 30 minutes and were additionally treated with traditional swallowing rehabilitation for 30 minutes. In contrast, patients in the control group were only treated with traditional swallowing rehabilitation for 30 minutes. Masseter muscle thickness was measured using ultrasonography before and after intervention, and bite force was measured using an bite force meter. Results: The experimental group showed significant improvement in masseter muscle thickness and bite force compared to the control group. Conclusion: NMES combined with traditional dysphagia rehabilitation is effective in improving masseter muscle thickness and bite force in patients with dysphagia after stroke.

In this study, we investigated the effects of neuromuscular electrical stimulation (NMES) on the treatment of 20 acute stroke patients with dysphagia. For both the treated and control groups, the basic facial stimulation training was conducted for 30 minutes, five times a week, for four weeks. NMES was performed on the treated group only, for 30 minutes each time. Both groups were evaluated according to the functional dysphagia scale (FDS) using a videofluoroscopic swallowing study (VFSS). After the treatment was performed for four weeks, the FDS results of the treated group showed a significance difference in oral transit time in the oral phase and in the triggering of pharyngeal swallow fluid, laryngeal elevation and epiglottic closure, nasal penetration, residue in valleculae, coating of pharyngeal wall after swallow fluid, and pharyngeal transit time in the pharyngeal phase. In addition, the treated group showed a significant difference in laryngeal elevation and epiglottic closure, nasal penetration, and pharyngeal transit time in the pharyngeal phase after the treatment compared to the control group. The results of this study showed that neuromuscular electrical stimulation may be an effective method of treating dysphagia in acute phase stroke patients.
