Objective : The purpose of this study is to investigate the effect of self swallowing exercise program with neuromuscular electrical stimulation(NMES) on swallowing function. Methods : Subjects who were diagnosed in dysphagia were randomly divided into the control group or experimental group. Both group were received NMES during 60 minutes with traditional swallowing therapy during 30 minutes. Additionally the experimental group was received self swallowing exercise during 30 minutes. We invested subject's characteristics through medical chart. We used VDS(Videofluoroscopic Dysphagia Scale) and PAS(Penetration Aspiration Scale) for assessing the swallowing function. Results : There were not significantly different in both group's pre swallowing function. The control group was significantly improved on pyriform sinus residue, aspiration, and VDS total score(p<.05). The experimental group was significantly improved on vallecular residue, pyriform sinus residue, and VDS total score(p<.05). Both group's difference of pre and post swallowing function were not significantly different. Conclusion : Self swallowing exercise and traditional swallowing therapy with NMES and traditional swallowing therapy with NMES are positive effect on swallowing function.

PURPOSE: This study was conducted to find out the effects of neurocognitive rehabilitation therapy on the swallowing function and quality of life of stroke patients. METHODS: Thirty patients were selected and randomly allocated into an experimental and a control group. Patients in the experimental group received 15 minutes of neurocognitive rehabilitation treatment combined with 15 minutes of traditional treatment. For the control group, patients received 30 minutes of traditional dysphasia treatment. The experiments were conducted for 30 minutes a day, five times a week, for four weeks. New VFSS and SWAL-QOL were administrated to evaluate the outcomes. RESULTS: Swallowing functions were significantly improved in the experimental group and the control group (p < .05), but there was no statistically significant difference in pre- and post-interventional swallowing between the groups (p > .05). The quality of life was also significantly improved (p < .05) for both groups, but there was a statistically significant difference between the two groups (p > .05). Third, a correlational analysis between swallowing function and quality of life revealed a moderate correlation between New VFSS and SWAL-QOL (p < .05). CONCLUSION: The results of this study suggest that swallowing therapy through neurocognitive rehabilitation treatment program could be helpful for improving swallowing function and quality of life in stroke patients. Although there was no statistically significant changes from traditional rehabilitation therapy, training in recognizing the senses in the oral cavity and external environment through neurocognitive rehabilitation therapy can be applied as one of the treatment options.

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 was conducted to confirm the effect of the oral motor facilitation technique (OMFT) on oral motor function in stroke patients. Methods : This study was conducted on 72 stroke patients with dysphagia were included. Thirty-six patients were randomly assigned to the experimental and control groups were randomly classified into 36 patients each using a random table, and a two-group pre-post test was designed. The experimental group underwent OMFT, and the control group underwent traditional dysphagia therapy for 30 min, once a day, 5 times a week for 4 weeks, for a total of 20 sessions. The Comprehensive Orofacial Function Scale (COFFS) was used to evaluate oral motor function. Repeated-measures analysis of variance (ANOVA) was performed to confirm the effect of the period, and an independent t-test was performed to analyze the difference in change between the two groups. Results : Total COFFS scores improved in both groups. The experimental group showed significant changes in mandibular and lip movements, cheek blows, and tongue movements. In addition, there were significant differences depending on the intervention period in terms of masticatory distribution, food spillage, swallowing of solid and liquid foods, and voice changes. There were significant differences in the mandibular opening and closing categories between the two groups. Conclusion : OMFT is effective in improving oral motor function in stroke patients with dysphagia and can be used as basic evidence in clinical practice.
