Abstract
OBJECTIVE Dysphagia is a common clinical condition characterized by difficulty in swallowing. It is sub-classified into oropharyngeal dysphagia, which refers to problems in the mouth and pharynx, and esophageal dysphagia, which refers to problems in the esophageal body and esophagogastric junction. Dysphagia can have a significant negative impact one's physical health and quality of life as its severity increases. Therefore, proper assessment and management of dysphagia are critical for improving swallowing function and preventing complications. Thus a guideline was developed to provide evidence-based recommendations for assessment and management in patients with dysphagia. METHODS Nineteen key questions on dysphagia were developed. These questions dealt with various aspects of problems related to dysphagia, including assessment, management, and complications. A literature search for relevant articles was conducted using Pubmed, Embase, the Cochrane Library, and one domestic database of KoreaMed, until April 2021. The level of evidence and recommendation grade were established according to the Grading of Recommendation Assessment, Development and Evaluation methodology. RESULTS Early screening and assessment of videofluoroscopic swallowing were recommended for assessing the presence of dysphagia. Therapeutic methods, such as tongue and pharyngeal muscle strengthening exercises and neuromuscular electrical stimulation with swallowing therapy, were effective in improving swallowing function and quality of life in patients with dysphagia. Nutritional intervention and an oral care program were also recommended. CONCLUSION This guideline presents recommendations for the assessment and management of patients with oropharyngeal dysphagia, including rehabilitative strategies.

Abstract
PURPOSE To investigate the dosages of swallowing exercises reported in intervention studies on post-stroke dysphagia through systematic review. METHODS Five electronic databases were searched from inception until February 2022 with reference tracing of included studies. Studies were included, where adults with post-stroke dysphagia received rehabilitative, behavioural swallowing exercises, pre/post outcomes were reported, and intervention dosage was described in detail, including frequency, intensity, time, and type of exercise. Two reviewers independently screened studies and rated quality using ASHA Levels of Evidence tool. Data was tabulated and narratively described. RESULTS 54 studies were included with a total 1501 participants. Studies included 28 randomised controlled trials, 8 non-randomised controlled trials, 12 pre/post studies, 3 retrospective case controls and 3 case studies. Results showed inconsistent reporting of intervention dosage, with intensity the least consistently reported dosage component. While swallowing intervention was most commonly provided five times per week for four weeks, there was a wide breadth of type, frequency, intensity and duration of swallowing exercises reported. Dosage under-reporting and variation was particularly observed in "standard care" co-interventions or control groups. Study strengths included following PRISMA guidelines, providing a comprehensive review of swallowing exercise methodology and dosages, and including non-English studies. The limitation was lack of meta-analysis due to the heterogeneity of included studies. CONCLUSIONS Dosages of swallowing exercises are inconsistently reported and vary significantly in post-stroke dysphagia studies. Results indicate the need for consistent and comprehensive dosage reporting in dysphagia studies, and for further research into evidence-based principles to optimise swallowing exercise dosages.

Abstract
BACKGROUND Neurogenic bowel dysfunction (NBD) is a common complication in stroke patients. OBJECTIVE To investigate the effect of rectal balloon ice water stimulation on the rehabilitation of patients with NBD after a cerebral stroke. METHODS Forty stroke patients with NBD were selected between March and August 2022 and randomly divided into a study group (n = 20) and a control group (n = 20). Based on routine rehabilitation training, rectal balloon ice water stimulation or finger rectal stimulation were performed on the study or control group, respectively. After two weeks, the changes in the NBD, self-rating depression scale (SDS) and self-rating anxiety scale (SAS) scores were compared between the two groups. RESULTS Before the intervention, there were no significant differences in age, sex ratio, and NBD, SDS and SAS scores between the two groups (p > 0.05). The NBD, SDS and SAS scores of both groups were significantly decreased following intervention (p < 0.05). After 2 weeks of intervention, the NBD score of the study group was significantly lower than that of the control group (5.50±1.28 vs 6.45±1.05; p = 0.014). The SDS score of the study group was lower than that of the control group, and the difference was statistically significant (32.30±2.81 vs 44.05±2.19; p = 0.014). The study group also had significantly lower SAS scores than the control group (p = 0.024). In addition, the incidence of dizziness, headaches, nausea, vomiting and abdominal pain and distension in the study group was significantly lower than in the control group (p < 0.05). CONCLUSION Rectal balloon ice water stimulation can significantly improve stroke patients with NBD's intestinal function and psychological status.

Abstract
Objective Aspiration is a common complication after tracheostomy in patients with acquired brain injury (ABI), resulting from impaired swallowing function, and which may lead to aspiration pneumonia. The Passy-Muir Tracheostomy and Ventilator Swallowing and Speaking Valve (PMV) has been used to enable voice and reduce aspiration; however, its mechanism is unclear. This study aimed to investigate the mechanisms underlying the beneficial effects of PMV intervention on the prevention of aspiration. Methods A randomized, single-blinded, controlled study was designed in which 20 tracheostomized patients with aspiration following ABI were recruited and randomized into the PMV intervention and non-PMV intervention groups. Before and after the intervention, swallowing biomechanical characteristics were examined using video fluoroscopic swallowing study (VFSS) and high-resolution manometry (HRM). A three-dimensional (3D) upper airway anatomical reconstruction was made based on computed tomography scan data, followed by computational fluid dynamics (CFD) simulation analysis to detect subglottic pressure. Results The results showed that compared with the non-PMV intervention group, the velopharynx maximal pressure (VP-Max) and upper esophageal sphincter relaxation duration (UES-RD) increased significantly (P < 0.05), while the Penetration-Aspiration Scale (PAS) score decreased in the PMV intervention group (P < 0.05). Additionally, the subglottic pressure was successfully detected by CFD simulation analysis, and increased significantly after 2 weeks in the PMV intervention group compared to the non-PMV intervention group (P < 0.001), indicating that the subglottic pressure could be remodeled through PMV intervention. Conclusion Our findings demonstrated that PMV could improve VP-Max, UES-RD, and reduce aspiration in tracheostomized patients, and the putative mechanism may involve the subglottic pressure.

Abstract
Objective This study is aimed at comparing the treatment efficacy between catheter balloon dilation combined with cold fluid compensatory swallowing training and catheter balloon dilation alone on poststroke cricopharyngeal achalasia (CPA). Methods We conducted a single-blind, randomized controlled trial (RCT). Poststroke patients with CPA were divided into two groups: the control group (treated with catheter balloon dilation) and the trial group (catheter balloon dilation combined with cold fluid compensatory swallowing). Videofluoroscopic swallowing study (VFSS) was performed, and functional oral intake scale (FOIS) was used to evaluate and compare the swallowing function of patients in the 2 groups before and after intervention. Posttreatment VAS pain scores and recovery time were also measured. Results VFSS and FOIS scores in the two groups were improved after treatment (P < 0.05). In the trial group, VFSS scores in the pharyngeal phase and aspiration degree were significantly higher compared with the control group (P < 0.05) but not in the oral phase (P > 0.05). The difference in FOIS scores and patients' recovery time from intervention to eating mushy food between the trial and control groups was significant (P < 0.05), but not the VAS scores (P > 0.05). Conclusion The catheter balloon dilation combined with cold fluid compensatory swallowing was superior to catheter balloon dilation alone in terms of relieving dysphagia and reducing aspiration in patients with CPA following stroke. Long-term efficacy should be followed up with more objective and quantitative indicators in future studies.

Abstract
BACKGROUND Cricopharyngeal muscle dysfunction (CPD) management has been challenging in clinical practice. OBJECTIVE To compare the efficacy and safety of ultrasound-guided botulinum toxin injection and balloon catheter dilatation in treating CPD. METHODS Forty patients with CPD were randomly divided into two groups, namely the botulinum toxin injection group (BTX group) and balloon dilatation group (BD group). Patients in the BTX group received a single ultrasound-guided injection of 50 units of botulinum toxin type A, while the BD group received dilatation therapy five times per week, consecutively for two weeks. Relative opening percentage of the upper esophageal sphincter (UES), the penetration-aspiration scale (PAS), and the Dysphagia Outcome Severity Scale (DOSS) were evaluated by a videofluoroscopic swallowing study (VFSS) at baseline, 1-month, and 3-months posttreatment. The Functional Oral Intake Scale (FOIS) and Standardized Swallowing Assessment (SSA) were also used to evaluate participants' swallowing function at baseline and the 1-week, 2-week, 1-month, and 3-month follow-ups. RESULTS A generalized estimating equation (GEE) model revealed the significant main effect for time in UES, PAS, DOSS, FOIS, and SSA compared to baseline (P <0.05), while no group-by-time interactions (except for the PAS assessment) or main effect for treatment was detected among the above multiple variances. No systematic complications or severe adverse effects were noted. CONCLUSION Both ultrasound-guided botulinum toxin type A injections and balloon dilatation therapy have been proven as safe and effective treatments for CPD patients. Future clinical trials with longer follow-up periods and more participants are warranted.

Abstract
BACKGROUND Cricopharyngeal botulinum toxin (BTX) injection is one of the treatments for neurogenic cricopharyngeal dysfunction (CPD). We conducted this prospective study to investigate the effect and safety of BTX injection for neurogenic CPD with a novel guidance. METHODS Twenty-one patients with neurogenic CPD whose symptoms did not reduce after conventional swallowing therapy were included in this study. The impact of BTX injection on the swallowing function of the patients was evaluated. KEY RESULTS After the injection, the Functional Oral Intake Scale (FOIS) score increased in 17 of 21 patients (80.9%), which ranged from 1 to 3 (P < 0.001). Moreover, there was a significant reduction in the UES opening impairment (P < 0.01), UES residual pressure (P < 0.05), duration of UES relaxation, penetration-aspiration scale score (P < 0.05), secretion (P < 0.05), vallecular residue (P < 0.01), and left (P < 0.05) and right (P < 0.05) pyriform sinus residue. With at least 6 months of follow-up, we found that FOIS continued to increase in patients who showed improvement after the injection (i.e., FOIS 5-7 points), while it remained unchanged in patients without improvement after the injection. There were no side effects reported in this study. CONCLUSION & INFERENCES BTX injection into the cricopharyngeal muscle guided by ultrasound, catheter balloon, and electromyography possibly has a long-lasting effect that can effectively and safely improve the swallowing function of patients with neurogenic CPD.

Abstract
OBJECTIVE Current interventions of dysphagia are not generalizable, and treatments are commonly used in combination. We conducted a questionnaire survey on nurses and speech therapists regarding dysphagia rehabilitation to understand the current situation in Japan. METHODS The questionnaire was sent to 616 certified nurses in dysphasia nursing and 254 certified speech-language-hearing therapists for dysphagia. Based on "Summaries of training methods in 2014" by JSDR, 24 local indirect exercises, 11 general indirect exercises, and 13 direct exercises were selected. The Likert scale "How do you feel about each method" was used as follows: A; Frequency, B; Ease, C; Adherence, D; Effectiveness (1-5))?". RESULTS Two hundred fifty (40%) nurses and 145 (57%) speech-language-hearing therapists (ST) responded to the questionnaire. The direct exercise was associated with a significantly high score in every question. In indirect exercises, "Cervical range of motion exercise," "Orofacial myofunctional exercise," "Lip closure exercise." "Ice massage of pharynx" and "Huffing" were used relatively frequently. "Balloon dilatation therapy" and "Tube exercise" was associated with a relatively high discrepancy for two questions. Frequency" and the sum of "Ease," "Adherence," and "Effectiveness." was significantly correlated for local indirect exercises (r2 = 0.928, P < 0.01), general indirect exercises (r2 = 0.987, P < 0.01), and direct exercises (r2 = 0.996, P < 0.01) (Fig. 5). CONCLUSION This study examined the current situation of dysphagia rehabilitation in Japan. Our results aid to increase understanding and selection of rehabilitative treatments for dysphagia patients in Japan.

Abstract
BACKGROUND A swallowing disorder may occur following a brainstem stroke, especially one that occurs in the swallowing centers. Lateral medullary syndrome (referred to as LMS), a rare condition in which a vascular event occurs in the territory of the posterior inferior cerebellar artery or the vertebral artery, has been reported to lead to more severe and longer lasting dysphagia.
CASE SUMMARY We report two patients with dysphagia due to LMS and propose a novel technique named hyoid-complex elevation and stimulation technique (known as HEST). The two patients had no other functional incapacity back into life, but nasogastric feeding was the only possible way for nutrition because of severe aspirations. Swallowing function was evaluated by functional oral intake scale, modified water swallow test, surface electromyographic signal associated with video fluorography swallowing study to assess the situation of aspiration, pharyngeal residue, pharyngeal peristalsis, upper esophageal opening and the ability of deglutition. Both patients were treated with the HEST method for dysphagia and recovered quickly.
CONCLUSION HEST is effective for shortening the in-hospital time and improving the quality of life for patients with dysphagia who suffer from LMS and likely other strokes.

Abstract
OBJECTIVE This study investigated the effects of transcranial direct current stimulation (tDCS) combined with conventional swallowing training on the swallowing function in brainstem stroke patients with cricopharyngeal muscle dysfunction (CPD). METHODS Twenty-eight brainstem stroke patients with CPD were assigned randomly to an anodal tDCS group or a sham tDCS group. The patients received anodal tDCS or sham tDCS over the bilateral oesophageal cortical area combined with simultaneous catheter balloon dilatation and conventional swallowing therapy for 20 days. Swallowing function was assessed using the functional oral intake scale (FOIS) and the functional dysphagia scale (FDS) and by measuring the pharyngoesophageal Segment Opening (PESO) before and immediately after the intervention. RESULTS Both groups showed a significant improvement in the FDS, FOIS and PESO scores immediately after the intervention (all p < .005). However, compared with the sham stimulation group, the anodal tDCS group showed greater improvements in the FDS, FOIS and PESO scores immediately after the intervention (all p < .005). CONCLUSION The bihemispheric anodal tDCS combined with simultaneous catheter balloon dilatation and conventional swallowing therapy effectively improves the swallowing function in patients with CPD caused by a brainstem stroke. tDCS may be an effective adjuvant therapy in CPD rehabilitation.

Abstract
Purpose Severe dysphagia with weak pharyngeal peristalsis after dorsal lateral medullary infarction (LMI) requires long-term tube feeding. However, no study is currently available on therapeutic effectiveness in severe dysphagia caused by nuclear damage of vagus nerve after dorsal LMI. The purpose of the present investigation was to explore the potential of transcutaneous vagus nerve stimulation (tVNS) to improve severe dysphagia with weak pharyngeal peristalsis after dorsal LMI. Method We assessed the efficacy of 6-week tVNS in a 28-year-old woman presented with persisting severe dysphagia after dorsal LMI who had been on nasogastric feeding for 6 months. tVNS was applied for 20 min twice a day, 5 days a week, for 6 weeks. The outcome measures included saliva spitted, Swallow Function Scoring System, Functional Oral Intake Scale, Clinical Assessment of Dysphagia With Wallenberg Syndrome, Yale Pharyngeal Residue Severity Rating Scale, and upper esophagus X-ray examination. Results After tVNS, the patient was advanced to a full oral diet without head rotation or spitting. No saliva residue was found in the valleculae and pyriform sinuses. Contrast medium freely passed through the upper esophageal sphincter. Conclusion Our findings suggest that tVNS might provide a useful means for recovery of severe dysphagia with weak pharyngeal peristalsis after dorsal LMI.

Abstract
BACKGROUND Dysphagia (swallowing problems), which is common after stroke, is associated with increased risk of death or dependency, occurrence of pneumonia, poor quality of life, and longer hospital stay. Treatments provided to improve dysphagia are aimed at accelerating recovery of swallowing function and reducing these risks. This is an update of the review first published in 1999 and updated in 2012. OBJECTIVES To assess the effects of swallowing therapy on death or dependency among stroke survivors with dysphagia within six months of stroke onset. SEARCH METHODS We searched the Cochrane Stroke Group Trials Register (26 June 2018), the Cochrane Central Register of Controlled Trials (CENTRAL; 2018, Issue 6) in the Cochrane Library (searched 26 June 2018), MEDLINE (26 June 2018), Embase (26 June 2018), the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (26 June 2018), Web of Science Core Collection (26 June 2018), SpeechBITE (28 June 2016), ClinicalTrials.Gov (26 June 2018), and the World Health Organization International Clinical Trials Registry Platform (26 June 2018). We also searched Google Scholar (7 June 2018) and the reference lists of relevant trials and review articles. SELECTION CRITERIA We sought to include randomised controlled trials (RCTs) of interventions for people with dysphagia and recent stroke (within six months). DATA COLLECTION AND ANALYSIS Two review authors independently applied the inclusion criteria, extracted data, assessed risk of bias, used the GRADE approach to assess the quality of evidence, and resolved disagreements through discussion with the third review author (PB). We used random-effects models to calculate odds ratios (ORs), mean differences (MDs), and standardised mean differences (SMDs), and provided 95% confidence intervals (CIs) for each.The primary outcome was functional outcome, defined as death or dependency (or death or disability), at the end of the trial. Secondary outcomes were case fatality at the end of the trial, length of inpatient stay, proportion of participants with dysphagia at the end of the trial, swallowing ability, penetration aspiration score, or pneumonia, pharyngeal transit time, institutionalisation, and nutrition. MAIN RESULTS We added 27 new studies (1777 participants) to this update to include a total of 41 trials (2660 participants).We assessed the efficacy of swallowing therapy overall and in subgroups by type of intervention: acupuncture (11 studies), behavioural interventions (nine studies), drug therapy (three studies), neuromuscular electrical stimulation (NMES; six studies), pharyngeal electrical stimulation (PES; four studies), physical stimulation (three studies), transcranial direct current stimulation (tDCS; two studies), and transcranial magnetic stimulation (TMS; nine studies).Swallowing therapy had no effect on the primary outcome (death or dependency/disability at the end of the trial) based on data from one trial (two data sets) (OR 1.05, 95% CI 0.63 to 1.75; 306 participants; 2 studies; I² = 0%; P = 0.86; moderate-quality evidence). Swallowing therapy had no effect on case fatality at the end of the trial (OR 1.00, 95% CI 0.66 to 1.52; 766 participants; 14 studies; I² = 6%; P = 0.99; moderate-quality evidence). Swallowing therapy probably reduced length of inpatient stay (MD -2.9, 95% CI -5.65 to -0.15; 577 participants; 8 studies; I² = 11%; P = 0.04; moderate-quality evidence). Researchers found no evidence of a subgroup effect based on testing for subgroup differences (P = 0.54). Swallowing therapy may have reduced the proportion of participants with dysphagia at the end of the trial (OR 0.42, 95% CI 0.32 to 0.55; 1487 participants; 23 studies; I² = 0%; P = 0.00001; low-quality evidence). Trial results show no evidence of a subgroup effect based on testing for subgroup differences (P = 0.91). Swallowing therapy may improve swallowing ability (SMD -0.66, 95% CI -1.01 to -0.32; 1173 participants; 26 studies; I² = 86%; P = 0.0002; very low-quality evidence). We found no evidence of a subgroup effect based on testing for subgroup differences (P = 0.09). We noted moderate to substantial heterogeneity between trials for these interventions. Swallowing therapy did not reduce the penetration aspiration score (i.e. it did not reduce radiological aspiration) (SMD -0.37, 95% CI -0.74 to -0.00; 303 participants; 11 studies; I² = 46%; P = 0.05; low-quality evidence). Swallowing therapy may reduce the incidence of chest infection or pneumonia (OR 0.36, 95% CI 0.16 to 0.78; 618 participants; 9 studies; I² = 59%; P = 0.009; very low-quality evidence). AUTHORS' CONCLUSIONS Moderate- and low-quality evidence suggests that swallowing therapy did not have a significant effect on the outcomes of death or dependency/disability, case fatality at the end of the trial, or penetration aspiration score. However, swallowing therapy may have reduced length of hospital stay, dysphagia, and chest infections, and may have improved swallowing ability. However, these results are based on evidence of variable quality, involving a variety of interventions. Further high-quality trials are needed to test whether specific interventions are effective.
