The purpose of this study is to investigate the effect of swallowing training of high viscosity bolus for swallow function of stroke patients with dysphagia. This study subjects, acute stroke 18 patients, which were recruited to receive treatment in inpatient at general hospital, located in Kyunggido. Subjects were randomly allocated in experimental group and control group. Experimental group performed swallowing training of high viscosity bolus, while control group conducted Traditional dysphagia therapy. Both groups received treatment 30 minutes a day five times a week for four weeks. The assessment was conducted FDS(: Functional Dysphagia Scale), PAS(: Penetration Aspiration Scale), ASHA NOMS(: American Speech-language-hearing Association National Outcomes Measurements System Swallowing Scale) to compare swallow function for both group. Both groups showed significant improvements after intervention in all measures(p<.05). Change score between the two groups showed a significant improvement on experimental group than control group in FDS(p<.05). Swallowing training of high viscosity bolus could have a positive impact on swallow function for acute stroke patients with dysphagia.

Purpose : The goal of this study is to estimate the effect of SSP electrical stimulation applied to acupoints as conducted in oriental medicine on the swallowing function of patients with swallowing difficulties caused by stroke. Methods : Twenty-two hemiplegic stroke patients with swallowing difficulties were divided into an intervention-only group (Group I; n=11) and an intervention-SSP electrical stimulation group (Group II; n=11). Therapeutic intervention was performed on participants in the intervention-only group and the intervention-SSP electrical stimulation group, for 20 minutes per session, three times per week, for four weeks. In this study, SSP electrical stimulation to the acupoints (Cheondol, Yomchon, Budol, Pungji, and Sanyinjian) of stroke patients with swallowing difficulties was applied, and to investigate the effects of SSP electrical stimulation, Clinical dysphagia scale (CDS) and ultrasonography assessment was used to measure pre and post-intervention scores. Results : In the clinical dysphagia scale assessment, the post-intervention score for group II had significant enhancement unlike group I. In the ultrasonography assessment, the hyolaryngeal movement in group II showed significant increase in the swallowing function unlike group I. Conclusion : From the above results, significant effects came from SSP electrical stimulation of 3Hz, biphasic wave, continuous current when applied to the acupoints as conducted in oriental medicine to improve the swallowing function of stroke patients.

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.

The purpose of this study was to examine changes in the swallowing function with chronic stroke patient. Ten chronic stroke patients with dysphagia followed up for 3 months. Eight normal age match subjects were also participated. A total of 18 participated in this study and they were classified into two groups (stroke patient group and normal control group). Participants underwent videofluoroscopic swallowing examination. The swallowing function was evaluated over time. Oral transit duration, pharyngeal transit duration, laryngeal response duration, Modified Barium Swallowing Impairment Profile ($MBSImP^{TM(c)}$), and Functional Oral Intake Scale (FOIS) were applied. Chronic stroke patient group were showed significantly longer oral transit duration, pharyngeal transit duration and laryngeal response duration than normal control group at baseline. After 3 months in stroke patient group, the mean oral components score of MBSImP (1~5) significantly decreased and the mean score on FOIS increased compared to baseline. In conclusion, oral swallowing function and oral intake function improved by the 3 month evaluation. These results describe changes in swallowing function with chronic stroke patients over time and provide basic informations to understand dysphagia.

The experimental group has been proceeded total 12 times based on 3 times per 30~50 minutes at a supplied place in the PNF program. The results of this study were as follows. First, the dysphagia scale of the experimental group that was provided with PNF, had a considerable statistic difference. Secondly, the oral pharyngeal functions of the experimental group that was provided with PNF, had a considerable statistic difference. Thirdly, the swallowing speed of the experimental group that was provided with PNF, had a statistic difference in the swallowing speed reduced of the first set, in total. Therefore, PNF is informed to have a effect in advancing the swallowing function of the stroke patients. And in the future, it is considered that researches that it develops the motor program in which the various techniques are combined and it can contribute to the swallowing functions for patients of stroke.

Larynx plays an important role in phonation and protection of the respiratory tract during swallowing. The reduced anatomical and physiological function in elevation of larynx and glottis closure can cause problems in voice and swallowing. The present study investigated the Korean version of handicap index of dysphagia in elderly Koreans. Therefore, 60 normal elderly Koreans ranged from 65 to 95 and 20 normal Korean young adults aged from 20 to 25 were participated in this study to compare total (T), physical (P), functional (F), and emotional (E) index scores between two groups as well as among sub groups (60s, 70s, 80s) in elderly. For swallowing, total and sub dysphagia handicap index (DHI) scores, voice quality during /a/phonation following swallowing (saliva and water), intensity of coughing, and L-DDK were measured. The results showed that functional (P), physical (P), emotional (E) scores as well as total (T) score were significantly different between young adults and old adults in DHI(p<.05). Additionally, there was a negative correlation between total DHI score and intensity of coughing (r=-.51) as well as L-DDK (r=-.70). These findings suggest that a slow rate in vocal fold adduction and reduced intensity of coughing in the elderly affect swallowing function. Thus, recently translated Korean version of DHI may be useful as supplement in evaluating the swallowing problems in elderly people.

Purpose: This study aimed to verify the effects of a swallowing training program on swallowing function and depression for nursing home residents with dysphagia after stroke. Methods: This is a quasi-experimental study with non-equivalent control group pre-post test design. The program (oro-facial muscle strengthening exercises, swallowing exercises, expiratory muscle strengthening exercises, and brain stimulation exercises) applied to the experimental group three times per week for eight weeks, 40-45 minutes for each intervention. The final data from 42 people (21 experimental and 21 control) were analyzed by SPSS/WIN 25.0 using descriptive statistics. 𝜒² test, t-test, Wilcoxon rank sum test, and Friedman test. Results: The experimental group was significantly improved than control group in oro-facial muscle strength, swallowing symptoms (Z=-2.22, p=.026), and oral intake function level (Z=-2.00, p=.046). However, there was no significant difference between two groups in depression. Conclusion: This study is meaningful in that it reorganized and mediated a swallowing training program as a safe, non-invasive exercise that nurses can implement in a nursing facility with limited medical personnel and it could be easily followed by older adults.

In this study, a systematic review was conducted to analyze the method of applying sEMG to evaluate the swallowing function of the elderly at each stage of swallowing, and to help objectively measure the swallowing stage of the older adults in clinical practice. From 2011 to 2021, 7 studies that met the selection criteria were selected using Pubmed, Scopus, and Web of Science (WoS). As a result of this study, the older adults and adults were divided into an experimental group and a control group and the swallowing phase was analyzed using sEMG only for the older adults. sEMG was used to evaluate swallowing in the oral and pharyngeal stages, and the sEMG attachment site was attached to the swallowing muscle involved in each stage. The collected sEMG data were filtered using a bandpass-filter and a notch-filter, and were analyzed using RMS, amplitude, and maximum spontaneous contraction. In this study, it was found that sEMG can be used as a tool to objectively and quantitatively evaluate the swallowing function in stages. Therefore, it is expected that this study will activate various studies that incorporate sEMG to evaluate the swallowing function in stages.

Purpose: This study was to identify the effects of oropharyngeal sensory stimulation on a functional oral intake scale, ore-pharyngeal swallowing functions, and aspiration pneumonia symptoms with nasogastric tube insertion in stroke patients. Method: This study was a nonequivalent control group non-synchronized design. The subjects or the study were 32 patients who were hospitalized in Kosin Gaspel hospital. The experimental subjects were stimulated for $10{\sim}20$ minutes, 1 time per day. The intervention was implemented for 2 weeks. Result: Participants in the experimental group significantly received a higher score in ore-pharyngeal swallowing function than those in the control group. However the participants in the experimental group only got a high score in the function oralintake scale which doesn't imply a statistical significance. In addition, they didn't geta remarkably higher score in aspiration pneumonia symptoms than those in the control group. Conclusion: This study demonstrates that oropharyngeal sensory stimulation is effective in promoting recovery oro-pharyngeal swallowing function of nasogastric tube insertions in stroke patients.

The purpose of current investigation was identified to the effects of swallowing training with surface electromyography biofeedback on swallowing function and dietary level, satisfaction in acute stroke patients with dysphagia. Sixteen acute stroke patients with dysphagia was participated in our study. All stroke paitents were allocated in randomly to experiemental group(n=8) and control group(n=8). Both group received traditional dysphagia therapy during 30min/day, five per week, for four weeks. experimental group was perfomed swallowing training with surface electromyography biofeedback, additionally 30 min/day, and control group received only swallowing training, additionally 30 min/day. Assessments evaluated Functional Dysphagia Scale(FDS) and Penetration-Aspiration Scale(PAS) for measure of swallowing function, and Functional Oral Intake Scale(FOIS) assessed for measure of dietary level. satisfaction assessed by using Visual Analog Satisfaction Scale(VASS). In results, after intervention both group improved significant on swallowing function, and dietary level, compared to before intervention(p<0.05). After intervention, satisfaction of both group was not significant difference(p>0.05). In comparison of change score between two group, experimental group improved significantly than control group in dietary level(p<0.05). Swallowing training with surface electromyography biofeedback may be a effective dysphagia therapy to improve on dietary level in acute stroke patients with dysphagia.
