Background: The effect of mobilization on lumbar back pain has been fully described in several clinical aspects, but evidence for muscle strength would be still less clear. Objective: To assess the effect of lumbar mobilization on lower limb strength in healthy individuals. Methods and Analysis: Healthy people aged 18-65 will be included regardless of race or sex. Original peer-reviewed primary reporting randomized controlled trials (RCTs) will be included. Electronic databases, such as MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Web of Science, Pedro, CINAHL, ClinicalTrials.gov will be searched from inception until July 30. Only studies published in English will be included in this review. Two reviewers will complete the screening for eligibility independently, and the other two reviewers will also complete the risks of data extraction and bias assessment independently. Lower Limb strength will be assessed as primary outcome, and particular intervention or participant characteristics will be assessed as the secondary outcomes. Meta-analysis will be conducted using Review Manager 5.3.3, and evidence level will be assessed using the method for Grading of Recommendations Assessment, Development and Evaluation. Outcomes will be presented as the weighted mean difference or standardized mean difference with 95% CI. If I² ≤ 50%, P>.1, the fixed effect model will be used, otherwise, random-effects model will be used. Ethics and dissemination: This review might not be necessary ethical approval because it does not require individual patient's data; these findings will be published in conference presentations or peer-reviewed journal articles. PROSPERO registration number: CRD42020150144.

To select 10 representatives for the ecotourism networks around the areas bordering national rivers in Korea, the spatial ranges for ecotourism have been established, the ecotourism potential analyzed, and the ecotourism resources information collected by the Regional Environmental Offices and the Korea National Park Service has undergone reviews, amendments, supplements, and verification processes through familiarization tour previews, and the following main results have been derived. First, the spatial ranges of the eco-tourism networks have been set as the watershed areas that include areas around the four major rivers and the rivers. Second, the areas with high potential value for ecotourism were selected through the analysis of ecotourism potential. Since EGIS was used for the analysis, it was inevitable that insufficient amount of localized information was reflected, and the use of the results as reference for the potential would be feasible. Third, it was possible, by reviewing, amending and complementing the results of ecological resource information collected by the Regional Environmental Offices and the Korea National Park Service, to select 50 representative ecological resources around the national rivers. The selected resources were considered for the adjacency, attractiveness of ecological resources, and uniqueness of the national rivers, and they were derived by screening expert advice, official opinion, and geographical analysis information. Fourth, 10 representative ecotourism networks based on watershed areas were selected, and suitable themes were given based on the resource characteristics. Fifth, the appropriateness for ecotourism has been confirmed, with the familiarization tour previews and survey results, preservation of the future ecotourism resources, and the establishment of the foundation as the basis. In the future, the remaining 9 ecotourism networks would also need to undergo a verification process such as familiarization tours. It is deemed that, through future ecotourism contests, if the programs that select locally-pioneered tourism programs resulting from the capacities of local entities and residents, then it would be more effective in discovering resources that are more localized and of higher regional value.

Objective : This study evaluated the role of smartphone application in the self-assessment of three psychiatric symptoms: stress, depression, and suicidal ideation. Methods : A total of 5,646 respondents were evaluated with three scales (Perceived Stress Scale, PSS, Center for Epidemiologic Study for Depression, CES-D, Scale for Suicidal Ideation, SSI) via smartphone application 'mindscan'. We analyzed the sociodemographic variables, the levels of three symptoms, and the association between the scores on all three scales. Results : The mean total scores of PSS, CES-D, and SSI were 24.86, 35.15, and 18.03, respectively. Women showed significantly higher scores on PSS, CES-D, and SSI when compared with men. Younger users showed a significantly higher score on all three scales when compared with older users. The scores on all three scales were higher than in other studies with off-line surveys. The PSS was positively correlated with CES-D (r=0.690), and with SSI (r=0.367). The CES-D was positively correlated with SSI (r=0.540). Conclusions : A smartphone application for mental health based on three scales (PSS, CES-D, and SSI) is a relatively useful screening tool compared with off-line general population surveys. The association between the three scales reflects the relationship between the three psychiatric symptoms observed in clinical practice.

Objectives: The aim of this review is to investigate clinical studies on Oriental medicine treatment for aphasia after cerebrovascular disease. Methods: Using the keywords 'Aphasia', 'Oriental medicine', 'Stroke' 'Cerebral infarction', 'Cerebral hemorrhage', and 'Clinic', we searched domestic databases, including "NDSL (National Discovery for Science Leaders)", "Korean Traditional Knowledge Portal", "OASIS (Oriental Medicine Advanced Searching Integrated System)", and "RISS (Research Information Sharing Service)". Each keyword was not searched individually, but combined in various ways. To investigate recent trends, we limited our search to papers published after 2000. Papers that did not include a specific treatment method or did not match the subject "Aphasia after stroke" were excluded. Results: Using the searching method, 13 studies were found. Of these, 12 studies were in the form of case reports, while one was in the form of a non-randomized controlled trial. These studies showed positive results for the use of Oriental medicine in terms of the Korean version of the Western Aphasia Battery (K-WAB), the evaluation form on functional performance capability and accuracy of articulatory organs developed by Lee, aphasia screening test refered in 'Assessment in Speech-Language Pathology' and adapted properly to Korean, the Communicative Ability in Daily Living Test (CADLT), the Korean Version-Boston Naming Test (K-BNT), and language assessment items included in CNS, and NIHSS. Conclusions: Of the 12 case reports, 11 studies showed positive results of the use of Oriental medicine for treatment of aphasia after cerebrovascular disease. However, more sophisticated and large-scale clinical research on aphasia should be conducted.

BACKGROUND/OBJECTIVES: Malnutrition risk and malnutrition among the elderly is a public health concern. In combating this health-related problem, it is critically important to evaluate the risk factors in a multidimensional way and to apply appropriate nutrition intervention based on the results. SUBJECTS/METHODS: A cross-sectional study was conducted on 215 elderly patients (32.6% male, 67.4% female) in a geriatric outpatient clinic of a hospital in Turkey. Nutritional questionnaires that incorporated the 24-h recall method were applied to determine general characteristics of patients, their health status, nutritional habits, and daily energy and nutrient intakes. Mini Nutritional Assessment was used to determine nutritional status. Relevant anthropometric measurements were obtained. RESULTS: The subjects' mean age was 76.1 ± 7.0 years, and the prevalence of malnutrition (n = 7) and risk of malnutrition (n = 53) among the 215 subjects was 3.2% and 24.7%, respectively. Patients with malnutrition or risk of malnutrition were found to be single, have a depression diagnosis, in an older age group, have less appetite, more tooth loss, have more frequent swallowing/chewing difficulty, and have more frequent meal skipping. In addition, mean daily energy, carbohydrate, fat, fiber, vitamin E, vitamin B1, vitamin B2, vitamin B6, vitamin C, folates, potassium, magnesium, phosphorus, iron intake, and water consumption were found to be statistically significantly low in subjects with malnutrition or risk of malnutrition. After performing regression analysis to determine confounding factors, malnutrition risk was significantly associated with marital status, loss of teeth, appetite status, and depression. CONCLUSIONS: Routine nutritional screening and assessment of the elderly should be performed. If nutritional deficiencies cannot be diagnosed early and treated, self-sufficiency in the elderly may deteriorate, resulting in increased institutionalization.

Background and Purpose: The Montreal Cognitive Assessment (MoCA) has been known as a screening test for detecting mild cognitive impairment (MCI) better than Mini-Mental State Examination (MMSE). However, in previous domestic studies, no significant difference was found in the discriminability between MoCA and MMSE. Researchers have suggested that this might be because older Koreans are less educated than older Westerners. This study was conducted to examine the effect of education on the discriminability of MoCA compared to the MMSE. Methods: Participants were 123 cognitively normal elderly, 118 with vascular MCI, 108 with amnestic MCI, 121 with vascular dementia, and 113 with dementia of the Alzheimer's type. The Korean-MoCA (K-MoCA) and Korean-MMSE (K-MMSE) were administered. Multiple regression analyses and receiver operating characteristic (ROC) curve analyses were performed. Results: In all participants, education significantly affected both K-MoCA and K-MMSE scores along with age. The effect of education was re-examined by subgroup analysis after dividing subjects according to the level of education. Effect of education on K-MoCA and K-MMSE was only shown in the group with <9 years of education. ROC curve analyses revealed that the discriminability of K-MoCA to differentiate between vascular MCI and normal elderly was significantly higher than that of K-MMSE. When re-examining subgroups divided by education level, however, this higher discriminability of K-MoCA disappeared in the group with <9 years of education. Conclusions: These results indicate no difference in discriminating cognitive deficits between K-MoCA and K-MMSE in Korean elderly with <9 years of education.

Objectives: The objective of this study is to develop a specialized clinical research protocol for acupuncture treatment specifically designed for disaster survivors based on insights from an expert survey. Methods: An expert panel comprising specialists in neuropsychiatry, acupuncture, and clinical research methodology was assembled. Initial data to inform the clinical research protocol design was collected utilizing open-ended responses, multiple-choice questions, and a 5-point Likert scale to gauge agreement levels. Next, this data was disseminated to a panel of experts. A cohesive clinical research protocol was then formulated during a core panel meeting by integrating insights from a panel of 10 experts. Results: The protocol developed herein entails a non-randomized controlled study involving participants aged 19~64 years old who have been identified as high-risk or cautious according to the National Trauma Center screening test. The study design includes the establishment of an active control group, which allows for the assessment of an additional effect through comparison with conventional therapy. The selected acupuncture approach involves a combination of manual acupuncture and ear acupuncture. For clinical outcome assessment, the Clinician-Administered Posttraumatic Stress Disorder Scale for DSM-5 was proposed to gauge trauma symptoms. Representative scales for various domains such as depression, anxiety, anger, insomnia, pain, and quality of life were also provided for reference. Conclusions: The developed protocol is anticipated to streamline the swift design and initiation of clinical trials during disaster scenarios. It is also designed to be scalable, thereby enabling its application in both non-randomized control group studies and single-group before-and-after comparisons.
