Dysphagia
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.

Geriatric Rehabilitation
Objective
The incidence of hip fractures is increasing worldwide with the aging population, causing a challenge to healthcare systems due to the associated morbidities and high risk of mortality. After hip fractures in frail geriatric patients, existing comorbidities worsen and new complications are prone to occur. Comprehensive rehabilitation is essential for promoting physical function recovery and minimizing complications, which can be achieved through a multidisciplinary approach. Recommendations are required to assist healthcare providers in making decisions on rehabilitation post-surgery. Clinical practice guidelines regarding rehabilitation (physical and occupational therapies) and management of comorbidities/complications in the postoperative phase of hip fractures have not been developed. This guideline aimed to provide evidence-based recommendations for various treatment items required for proper recovery after hip fracture surgeries. Methods Reflecting the complex perspectives associated with rehabilitation post-hip surgeries, 15 key questions (KQs) reflecting the complex perspectives associated with post-hip surgery rehabilitation were categorized into four areas: multidisciplinary, rehabilitation, community-care, and comorbidities/complications. Relevant literature from four databases (PubMed, EMBASE, Cochrane Library, and KoreaMed) was searched for articles published up to February 2020. The evidence level and recommended grade were determined according to the grade of recommendation assessment, development, and evaluation method. Results A multidisciplinary approach, progressive resistance exercises, and balance training are strongly recommended. Early ambulation, weigh-bearing exercises, activities of daily living training, community-level rehabilitation, management of comorbidities/complication prevention, and nutritional support were also suggested. This multidisciplinary approach reduced the total healthcare cost. Conclusion This guideline presents comprehensive recommendations for the rehabilitation of adult patients after hip fracture surgery. Citations Citations to this article as recorded by
Objective
Though clinical practice guidelines (CPGs) for cardiac rehabilitation (CR) are an effective and widely used treatment method worldwide, they are as yet not widely accepted in Korea. Given that cardiovascular disease is the second leading cause of death in Korea, it is urgent that CR programs be developed. In 2008, the Government of Korea implemented CR programs at 11 university hospitals as part of its Regional Cardio-Cerebrovascular Center Project, and three additional medical facilities will be added in 2019. In addition, owing to the promotion of CR nationwide and the introduction of CR insurance benefits, 40 medical institutions nationwide have begun CR programs even as a growing number of medical institutions are preparing to offer CR. The purpose of this research was to develop evidence-based CPGs to support CR implementation in Korea. Methods This study is based on an analysis of CPGs elsewhere in the world, an extensive literature search, a systematic analysis of multiple randomized control trials, and a CPG management, development, and assessment committee comprised of 33 authors—primarily rehabilitation specialists, cardiologists, and thoracic surgeons in 21 university hospitals and two general hospitals. Twelve consultants, primarily rehabilitation, sports medicine, and preventive medicine specialists, CPG experts, nurses, physical therapists, clinical nutritionists, and library and information experts participated in the research and development of these CPGs. After the draft guidelines were developed, three rounds of public hearings were held with staff members from relevant academic societies and stakeholders, after which the guidelines were further reviewed and modified. Principal Conclusions CR involves a more cost-effective use of healthcare resources relative to that of general treatments, and the exercise component of CR lowers cardiovascular mortality and readmission rates, regardless of the type of coronary heart disease and type and setting of CR. Individualized CR programs should be considered together with various factors, including differences in heart function and lifestyle, and doing so will boost participation and adherence with the CR program, ultimately meeting the final goals of the program, namely reducing the recurrence of myocardial infarction and mortality rates.

To determine whether the use of both videofluoroscopic swallowing study (VFSS) and radionuclide salivagram was beneficial for detecting aspiration-induced pneumonia in children with swallowing difficulty. From 2001 to 2016, children who underwent both VFSS and salivagram consecutively for suspected aspiration or dysphagia were included in the study. Demographic data, findings of VFSS and salivagram, and medical records were reviewed. Aspiration pneumonia (AP) was present in 34 out of 110 children; 48 showed positive aspiration findings in VFSS and 33 showed positive aspiration findings in salivagram. Among the 62 children who were negative of aspiration in VFSS, 12 (19.4%) showed positive aspiration findings in salivagram. Four out of 12 children were diagnosed with AP. The aspiration findings in both VFSS and salivagram were significantly related to AP. However, the aspiration findings in the two tests were weakly consistent. Even if one test showed negative aspiration, it was helpful to additionally detect AP using another test, which showed positive aspiration finding. If aspiration findings were positive in only one of the two tests, the probability of AP was 38.5%, whereas if they were positive in both tests, the probability increased to 66.7%. If the aspiration findings were negative in both tests, AP did not occur with a probability of 90%. Salivagram is a valuable tool for monitoring of aspiration in children with swallowing difficulties. It could be helpful in assessment of children at a high risk of AP, even if the VFSS showed negative aspiration findings. Thus, testing for AP using both VFSS and salivagram is desirable.

To investigate whether patterns of dysphagia and swallowing laterality differ according to the location of brain lesions in patients with stroke. Patients with stroke >20 years of age were enrolled in this study. A videofluoroscopic swallowing study (VFSS) including the anterior-posterior view was used to assess swallowing. Patterns of swallowing were classified into three types according to the width of barium sulfate flow while passing the pharyngoesophageal segment: right-side-dominant flow, left-side-dominant flow, and no laterality in flow. Laterality was defined when the width of one side was twice or more the width of the other side. A total of 92 patients who underwent swallowing function evaluations by VFSS were enrolled from Sep-tember 2012 to May 2013. Of these, 72 patients had supratentorial lesions (group I) and 20 patients had infratento-rial lesions (group II). Only 10 patients (13.9%) in group I and three patients (15.0%) in group II showed laterality. Of these 13 patients, laterality occurred on the left side regardless of the side of the brain lesion. No relationships were found between swallowing laterality and location of stroke or motor weakness. The results suggest that swallowing laterality was not prevalent among patients with stroke and that lesion side, location of the brain lesion, or motor weakness did not influence swallowing laterality. Although stroke can cause symptoms of dysphagia, it is difficult to conclude that stroke has a crucial impact on swallowing laterality. Citations Citations to this article as recorded by
To identify risk factors for dysphagia in tongue cancer patients. Dysphagia is a common complication of surgery, radiotherapy, and chemotherapy in tongue cancer patients. Previous studies have attempted to identify risk factors for dysphagia in patients with head and neck cancer, but no studies have focused specifically on tongue cancer patients. This study was conducted on 133 patients who were diagnosed with tongue cancer and who underwent a videofluoroscopy swallowing study (VFSS) between January 2007 and June 2012 at the Asan Medical Center. Data collected from the VFSS were analyzed retrospectively. Patients with aspiration were identified. Patients showed a higher incidence of inadequate tongue control, inadequate chewing, delayed oral transit time, aspiration or penetration, vallecular pouch and pyriform residue, and inadequate laryngeal elevation after surgery. Moreover, male gender, extensive tumor resection, a higher node stage, and more extensive lymph node dissection were major risk factors for aspiration in tongue cancer patients. Tongue cancer patients have difficulties in the pharyngeal phase as well as the oral phase of swallowing. These difficulties can worsen after tongue cancer surgery. Gender, the extent of tumor resection, and lymph node metastasis affect swallowing in tongue cancer patients. Physicians should take these risk factors into account when administering swallowing therapy to tongue cancer patients. Citations Citations to this article as recorded by
To translate the English version of the Pain Disability Questionnaire (PDQ) into Korean and to investigate the reliability and validity of the Korean version of the PDQ (K-PDQ) in patients suffering chronic disabling musculoskeletal disorders (CDMDs). The English version of the PDQ was translated into Korean. Ten patients with CDMDs were randomly selected for a pilot study to assess the comprehensibility of the pre-final version. One hundred and thirty-nine patients suffering from CDMDs for more than 3 months were enrolled in this study. Follow-up questionnaires were obtained to examine the test-retest reliability. Concurrent validity was evaluated by comparing the K-PDQ with the visual analogue scale (VAS). Construct validity was evaluated by comparing the K-PDQ with the brief form of the World Health Organization quality of life assessment instrument (WHOQOL-BREF) using Pearson correlation coefficient. Reliability was assessed using the intraclass correlation coefficient (ICC), and internal consistency was determined by Cronbach's alpha. Test-retest reliability was assessed in 70 patients, with an average time interval of 12 days. The ICC was 0.958 (p<0.001). Internal consistency reached Cronbach's alpha of 0.933 for the functional component and 0.870 for the psychosocial component. The correlation coefficient for the K-PDQ when compared with the VAS was 0.834 in the first assessment and 0.831 in the second assessment. All domains of the WHOQOL-BREF showed a significant negative correlation with the K-PDQ. The K-PDQ is a reliable and valid instrument for measuring disability and can be used to assess disability and treatment outcomes in Korean patients with CDMD.

To compare the effects of lumbar stabilization exercises and lumbar dynamic strengthening exercises on the maximal isometric strength of the lumbar extensors, pain severity and functional disability in patients with chronic low back pain (LBP). Patients suffering nonspecific LBP for more than 3 months were included prospectively and randomized into lumbar stabilization exercise group (n=11) or lumbar dynamic strengthening exercise group (n=10). Exercises were performed for 1 hour, twice weekly, for 8 weeks. The strength of the lumbar extensors was measured at various angles ranging from 0° to 72° at intervals of 12°, using a MedX. The visual analog scale (VAS) and the Oswestry Low Back Pain Disability Questionnaire (ODQ) were used to measure the severity of LBP and functional disability before and after the exercise. Compared with the baseline, lumbar extension strength at all angles improved significantly in both groups after 8 weeks. The improvements were significantly greater in the lumbar stabilization exercise group at 0° and 12° of lumbar flexion. VAS decreased significantly after treatment; however, the changes were not significantly different between the groups. ODQ scores improved significantly in the stabilization exercise group only. Both lumbar stabilization and dynamic strengthening exercise strengthened the lumbar extensors and reduced LBP. However, the lumbar stabilization exercise was more effective in lumbar extensor strengthening and functional improvement in patients with nonspecific chronic LBP.

To investigate the inter-rater agreement using the Videofluoroscopic Dysphagia Scale (VDS). The present study was designed as a multicenter, single-blind trial. A Videofluoroscopic Swallowing Study (VFSS) was performed using the protocol described by J.A Logemann. Thick-fluid, pureed food, mechanically altered food, regularly textured food, and thin-fluid boluses were sequentially swallowed. Each participant received a 3 ml bolus followed by a 5 ml bolus of each food material, in the order mentioned above. All study procedures were video recorded. Discs containing these video recordings in random order were distributed to interpreters who were blinded to the participant information. The video recordings were evaluated using a standardized VDS sheet and the inter-rater reliability was calculated. In total, 100 patients participated in this study and 10 interpreters analyzed the findings. Inter-rater reliability was fair in terms of lip closure (κ: 0.325), oral transit time (0.253), delayed triggering of pharyngeal swallowing (0.300), vallecular residue (0.275), laryngeal elevation (0.345), pyriform sinus residue (0.310), coating of the pharyngeal wall (0.310), and aspiration (0.393). However, other parameters of the oral phase were lower than those of the pharyngeal phase (0.06-0.153). Moreover, the summation of VDS reliability (intraclass correlation coefficient: 0.556) showed moderate agreement. VDS shows a moderate rate of agreement for evaluating the swallowing function. However, many of the parameters demonstrated a lower rate of agreement, particularly the oral phase parameters. Citations Citations to this article as recorded by
Objective
Primary frozen shoulder causes significant pain and progressively restricts shoulder movements. Diagnosis is primarily clinically based on patient history and physical examination. Management is mainly non-invasive owing to its self-limiting clinical course. However, clinical practice guidelines for frozen shoulder have not yet been developed in Korea. The developed guidelines aim to provide evidence-based recommendations for the diagnosis and treatment of frozen shoulder. Methods A guideline development committee reviewed the literature from four databases (PubMed, Embase, Cochrane Library, and KMbase). Using the PICO (Population, Intervention, Comparator, and Outcome) framework, the committee formulated two backgrounds and 16 key questions to address common clinical concerns. Recommendations were made using the Grading of Recommendations, Assessment, Development, and Evaluation framework. Results Diabetes, thyroid disease, and dyslipidemia significantly increase the risk of developing a frozen shoulder. Although frozen shoulder is often self-limiting, some patients may experience long-term disabilities. Ultrasound and magnetic resonance imaging should be used as adjunctive tools alongside clinical diagnosis, and not as independent diagnostic methods. Noninvasive approaches, such as medications, physical modalities, exercises, electrical stimulation, and manual therapy, may reduce pain and improve shoulder function. Other noninvasive interventions have limited evidence, and their application should be based on clinical judgment. Intra-articular steroid injections are recommended for treatment, and physiotherapy or hydrodilation with steroid injections can also be beneficial. Conclusion These guidelines provide evidence-based recommendations for diagnosing and treating primary frozen shoulder.
