Purpose: The purpose of the study was to identify the relationship between obesity and bone mineral density in middle aged women. Methods: A cross-sectional survey design was utilized with a check list and physiological measurements. A total of 827 convenient samples were recruited from women who lived in the community. Bone mineral density was measured by T-score using the pixi method of Lumar on the left heel. Descriptive statistics and pearson correlation coefficient were utilized for data analysis. Results: Most were assessed as having normal weight(37.9%) or obese (57.4%) by BMI. Only 32% was assessed as having normal bone mineral density, while 40.3% had osteopenia, and 27.7% as osteoporosis. The BMI scores were significantly related to age, and episodes of fractures. Those with lower bone mineral density reported significantly more episodes of fractures and chronic disease. The T scores of Bone mineral density were significantly correlated with the scores of BMI (r= .126, p< .001). Conclusion: There is a strong need to develop intervention programs for this age group to manage bone mineral density loss to prevent occurrences of osteoporosis, and episodes of fracture.

Purpose: The purposes of this study were to identify degrees of low back pain, knowledge of and educational needs for low back pain of patients with chronic low back pain and to investigate their relationships. Methods: Data were collected from questionnaires distributed to 83 patients with chronic low back pain at a hospital. Results: The low back pain score was $4.70{\pm}2.22$ out of 10. The degree of low back pain was a statistically significant difference according to gender, smoking, radiating pain and frequency and duration, daily life disturbance degree, sleep disturbance and depression. The knowledge score was 8.29 out of 13. The knowledge was a statistically significant difference according to smoking and degree of sleep disturbance. The educational needs score was 39.83 out of 50. The educational needs was a statistically significant difference according to age, duration of disease, radiating pain, standing time, depression, pain treatment experience, and treatment institutions. As the low back pain increased, the educational needs increased (r=.254, p=.021). There were no correlations between low back pain and knowledge (r=-.040, p=.720) and knowledge and educational needs (r=.061, p=.581). Conclusion: It is important to focus on items with statistically significant differences in pain, knowledge, and educational needs, and to select low knowledge and high educational needs items to develop a systematic education plan.

Purpose: This study was a comparative analysis of stroke-related factors between recurrent patients and non-recurrent patients. Methods: A retrospective cohort study design was used, and data were collected from March 2020 to April 2020 using electronic medical records. 244 patients (221 first-timers and 23 recurrent) were included in this study. Results: The stroke recurrence rate in 5 years was 9.4%, the readmission rate was 39.3%, and the mortality rate was 2.0%. The number of patients hospitalized for stroke was greater among men than among women. Of the patients, 60.7% had an underlying disease. With regard to daily life abilities, over 70% of participants needed more than moderate dependence and about 40% of participants had more than mild cognitive impairment. More than 50% were moved to wheelchairs or stretcher cars. The difference in the stroke readmission rate between recurrent and non-recurrent patients was statistically significant. Conclusions: Based on our findings, a program to prevent recurrence of stroke should be developed to considering age, ability of daily living, place of discharge, gait ability at discharge, and place of discharge.

Purpose: Metabolic syndrome is known as a factor that increases the incidence of chronic diseases, such as diabetes and cardiovascular disease. In particular, the metabolic syndrome among a middle-aged population is rapidly increasing from 15.6% to 31.9%. The purpose of this study was to investigate the effect of muscle strength exercise on the metabolic syndrome in middle aged. Methods: This study was a secondary data analysis using National Health and Nutrition Survey 8th, including 2,739 middle aged people (40~64 years old). We used multivariate logistic regression to identify risk factors associated with metabolic syndrome. Statistical analysis was performed using the SPSS 23.0 program. Results: There were 772 patients in the group with metabolic syndrome and 1,967 patients in the non-metabolic syndrome group. The risk of metabolic syndrome was 1.29 times higher in those who did not do muscle strength exercise than those who did exercise (OR=1.29, 95% CI=1.01~1.66). Conclusion: We have found that muscle strength exercise was effective in lowering the risk of developing metabolic syndrome in middle aged. Thus, it is necessary to develop practical muscle strength exercise and education programs.

Calcification in the tendon is a common disease especially in the rotator cuff. The condition can be treated conservatively in the chronic stage, but surgically in the acute stage. On the other hand there are few reports of calcification in the cruciate ligament of the knee joint, especially calcification of the posterior cruciate ligament. A 51-year-old patient with symptomatic calcification in the mid-substance of the posterior cruciate ligament was treated conservatively. The symptoms did not improve after eight months of conservative treatment, so arthroscopic surgery was performed. During arthroscopic removal of the calcification, the ligament was damaged beyond preservation. Eventually a posterior cruciate ligament reconstruction was performed. At two years after surgery, radiography confirmed no recurrence of the calcification, and the patient was free. We report this case study with a review of the relevant literature.

Developmental dysplasia of the hip broadly includes inadequate development of the hip joint involving the acetabulum or proximal femur, or both. Although ultrasonographic studies in neonates have greatly lowered the frequency of neglected or operatively treated cases, its sensitivity is less than desired. Hip dysplasia without subluxation is commonly diagnosed incidentally and strongly related to degenerative arthritis in females after the 4th decade. Hip dysplasia with subluxation shows symptoms through various periods, depending on its severity, especially for women with onset during pregnancy. A complete physical examination and early treatment for neonates are extremely important for obtaining satisfactory outcomes. To avoid underdiagnosis and to serve appropriate treatment on time, the authors recommend examining any suspicious hips in infants under two years of age. The study will discuss the diagnosis and primary treatment of developmental dysplasia of the hip.

Purpose: This study aimed to investigate the factors affecting the subjective health status (SHS) of low-income older adults living alone. Methods: This is a cross-sectional correlational study using secondary data analysis. Sociodemographic and health-related characteristics were included in this analysis. The health-related characteristics were categorized into three domains: physical, characterized by the number of chronic diseases and fall-related factors, timed up and go, and grip strength; psychological, in terms of depression and loneliness; and social, in terms of social support. Data were analyzed using descriptive analysis, t-test, ANOVA, Pearson's correlation coefficient, and multiple linear regression analysis. Results: The mean SHS score was 2.46 out of five. Several factors influenced the SHS of low-income older adults living alone, including sex, age, level of education, monthly income, and the three domains. Four significant predictive factors of SHS in low-income older adults living alone were identified (42.5%): the number of chronic diseases, fear of falling, depression, and social support. Conclusion: SHS is a critical factor for older adults living alone on a low-income. Hence, evaluating SHS and developing interventions to improve it periodically is necessay. Such interventions should consider chronic disease management, screening and mediation for depression and fear of falling, and strengthening their social support systems.

Purpose: This study was conducted to identify differences in health behavior, health-related quality of life, and depression between adult men and women during the COVID-19 pandemic. Methods: Data were obtained from 1,927 men and 2,314 women aged 19 to 64 who participated in the 7th Korea National Health and Nutrition Survey in 2020. Data were analyzed using complex sample x² test, complex sample general linear model, and complex sample logistic regression. Results: During the pandemic, men drank more alcohol (OR=2.34, 95% CI: 1.89~2.91) and smoked more (OR=7.89, 95% CI: 6.16~10.09) than women. In addition, men were 2.45 times more exposed to second-hand smoke at the workplace (95% CI: 1.78~3.37) and 1.4 times more exposed in public places (95% CI: 1.12~1.77). The rate of muscle exercise was higher among men than women (OR=2.09, 95% CI: 1.76~2.49). No difference in health-related quality of life was observed between men and women (t=0.17, p=.78), but women had higher depression scores (t=-3.14, p=.002). Conclusion: Customized sex-specific interventions should be developed during the COVID-19 pandemic. This kind of infectious disease disaster requires plans designed to reduce alcohol intake and smoking among men and interventions aimed at increasing muscle exercise among women. Strategies should also be formulated to reduce depression among women.

PURPOSE: This study compared the effects of proprioceptive sensation, subacromial space, and dynamic function according to proprioceptive neuromuscular facilitation (PNF), static stretching (SS), and complex rotational stretching (CRS). METHODS: Thirty students without any musculoskeletal disease who volunteered to participate were included in this study. The following metrics were measured to evaluate the function and stability under the normal conditions, with the PNF, SS, and CRS: special test and flexion, extension, abduction, adduction, internal rotation, external rotation (shoulder range of motion) and reaching distance on the medial (ME), superolateral (SL), inferolateral (IL), and subacromial space and proprioceptive sensation were evaluated. All measures were analyzed using one-way ANOVA and repeated measures of ANOVA. RESULTS: A clear difference in adduction in the range of motion was observed in all groups (p < .05). Significant differences could not be identified in all values in the error test, except for Ab (p < .05). Significant differences in reach were noted in all directions of the SS and PNF in the Me, SL, and IL (p < .05). After the intervention, significant differences in the average values could be identified in all groups except for the SS group after rest (p < .05). After the intervention, there was a significant difference between the CRS and SS and PNF groups (p < .05). CONCLUSION: The application of CRS is as helpful as the existing SS and PNF for improving the joint range of motion improvement, shoulder balance, and subacromial space.

Streptococcus intermedius is a small, non-motile, Gram-positive, non-sporeforming, and aerotolerant anaerobic coccus. It is a part of the normal microflora in the oral cavity and upper respiratory, gastrointestinal and female urogenital tracts. It is an opportunistic pathogen that causes serious infections in patients with immunocompromised states or cardiac diseases as a result of trauma or invasive procedures. We describe a case of septic arthritis of the hip caused by S. intermedius in an immunocompetent healthy 7-year-old boy without a history of periodontal disease or invasive procedures. He had hip joint pain three weeks ago, and the fever began on the day of the visit. He had been healthy and had not undergone any invasive procedures recently. Septic arthritis of the hip was indicated in the magnetic resonance imaging of the hip. S. intermedius was identified in the hip joint fluid aspiration and blood culture. He was successfully treated with surgical intervention and antibiotic therapy with ceftriaxone followed by amoxicillin for five weeks.
