BackgroundDysphagia is a common complication after stroke and is associated with the development of pneumonia. This study aimed to summarize the relationship between dysphagia and pneumonia in post-stroke patients.Materials and MethodsArticles published up to November 2021 were searched in the PubMed, Embase, Cochrane library, and Scopus databases. Studies that investigated the development of pneumonia in acute stroke patients with and without dysphagia were included. The methodological quality of individual studies was evaluated using the Risk Of Bias In Non-randomized Studies-of Interventions tool, and publication bias was evaluated using a funnel plot and Egger's test.ResultsOf 5,314 studies, five studies were included in the meta-analysis. The results revealed that the incidence of pneumonia was significantly higher in the dysphagia group than in the non-dysphagia group (OR 9.60; 95% CI 5.75–16.04; p < 0.0001; I2 = 78%). There was no significant difference in the mortality rate between the two groups (OR 5.64; 95% CI 0.83–38.18; p = 0.08; I2 = 99%).ConclusionDysphagia is a significant risk factor for pneumonia after stroke. The early diagnosis and treatment of dysphagia in stroke patients are important to prevent stroke-associated pneumonia.
ObjectiveTo investigate the effect of repetitive transcranial magnetic stimulation (rTMS) on neurological and functional recovery in patients with central cord syndrome (CCS) involving the upper extremities between the treated and non-treated sides of the treated group and whether the outcomes are comparable to that of the untreated control group.MethodsNineteen CCS patients were treated with high-frequency (20 Hz) rTMS over the motor cortex for 5 days. The stimulation side was randomly selected, and all the subjects received conventional occupational therapy during the rTMS-treatment period. Twenty CCS patients who did not receive rTMS were considered as controls. Clinical assessments, including those by the International Standard for Neurological Classification of Spinal Cord Injury, the Jebsen-Taylor Hand Function Test, and the O'Connor Finger Dexterity Test were performed initially and followed up for 1 month after rTMS treatment or 5 weeks after initial assessments.ResultsThe motor scores for upper extremities were increased and the number of improved cases was greater for the treated side in rTMS-treated patients than for the non-treated side in rTMS-treated patients or controls. The improved cases for writing time and score measured on the Jebsen-Taylor Hand Function Test were also significantly greater in number on the rTMS-treated side compared with the non-treated side and controls. There were no adverse effects during rTMS therapy or the follow-up period.ConclusionThe results of the application of high-frequency rTMS treatment to CCS patients suggest that rTMS can enhance the motor recovery and functional fine motor task performance of the upper extremities in such individuals.
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.
In dysphagia, food or water cannot be delivered safely through the oral cavity to the stomach; both are treated using texture-modified food and thickened fluid. Before, each country had its own diet modifications and texture measurement standards. In 2012, the International Dysphagia Diet Standardisation Initiative (IDDSI) was developed by several countries. Owing to cultural differences, it was necessary to determine whether the IDDSI could well be applied to clinicians and patients without difficulties in East Asia countries. To evaluate the IDDSI scale to find out the difficulties applying this scale in East Asia countries to educate the clinicians and patients. In May 2021, we enrolled physicians, nurses, nutritionists, and swallowing therapists involved in dysphagia treatment at a single center in Seoul. To evaluate the degree of understanding and difficulties of adapting IDDSI to clinicians in East Asia countries, we used the 17-item questionnaire with IDDSI sample foods and foods in Asian countries. In first 7 items, we compared IDDSI with the previously used scale based on the National Dysphagia Diet (NDD). In the next 10 questions, only the IDDSI levels were answered, and the absolute values of the answer–response differences were calculated. The IDDSI showed a significantly high intraclass correlation with the previously used NDD-based scale; the coefficient was higher for the nutritionists (0.988) and swallowing therapists (0.991). When evaluating whether the IDDSI could applied well in East Asia countries, the absolute values of the answer–response differences were lower than 0.5 in majority of levels, except for Level 4. Because the IDDSI framework might successfully be applied universally regardless of food culture, a worldwide standard for food rheology in dysphagia treatment might be possible.
