Purpose: The purpose of this study was to identify the prevalence of hypertension and its risk factors among community dwelling aged 65 and over in South Korea. Methods: A total of 1,367 subjects from the 2010 Korean National Health and Nutrition Examination Survey (KNHANES) were selected. The data analysis was conducted by SPSS WIN 19.0 using descriptive statistics, ${\chi}^2$-test, and logistic regression analysis. Results: The prevalence of hypertension was found to be 47.70%. Logistic regression analysis shows that hypertension was more prevalent as people became older; in females; in elderly who were not employed as compared to those employed; elderly with diabetes, and obesity as compared to those without these health conditions; as elderly who performed more moderate intensity exercise. While, education, household income, high risk alcoholic drinking, smoking, stress perception, usual activity, and eating out behavior were not associated with prevalence of hypertension in this study. Conclusion: The finding of prevalence of hypertension and its risk factors is expected to promote the screening or prevention strategy for community dwelling aged 65 and over at risk of hypertension in Korea.

The purpose of this study was to investigate the effectiveness of elastic band resistance training for muscle strength among community-dwelling older adults. The systematic review and meta-analysis was conducted by following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA). Data were pooled using fixed effect models. Sit to stand, arm curl, and grip strength were analyzed for main effects. Heterogeneity between studies was assessed using the I2 statistics and publication bias was evaluated by funnel plots. Twelves studies were included representing 611 participants. Elastic band resistance training was effective for lower (d=3.89, 95% CI: 3.03, 4.75) and upper extremity muscle strength (d=4.08, 95% CI: 2.94, 5.23). Heterogeneity was moderate and no significant publication bias was detected. Based on these findings, there is clear evidence that elastic band resistance training has significant positive effects on muscle strength among community-dwelling older adults. Further study will be needed to perform subgroup analysis using number of sessions and exercise intensity as predictors.

PURPOSE: It is known that work stress was linked to WRMDs in workplace. The purpose of this study was to identify the characteristics of work related musculoskeletal disorders (WRMDs) related to job stress among prosthetists and orthotists. METHODS: Eighty-six self-reported symptoms of discomfort (SRSD) and job stress were collected by questionnaire and analyzed. RESULTS: The results were as follows: Over 70% of respondents had WRMDs. The shoulder was the most painful region and each of "within 15 minutes", "once a week" and "severe moving or doing exercise" items were main characteristics in the SRSD. Finally, the "repetition of simple work" item in job stress ranked as resulting in "often discomfort" in over 43% of respondents. Additionally, there was a statistically significant correlation between job stress and pain intensity (p<.05, $r_s$=.36). CONCLUSION: Further studies are needed to identify the factors affecting musculoskeletal symptoms and job stress of prosthetists and orthotists in Korea.

Objective: In this study, we analyzed kinematic changes in the start phase of speed skating before and after physical training. Method: We introduced a new strength training program (2017) that was improved in terms of exercise type and intensity [%, one repetition maximum (1RM)] compared with the previous strength training program (2016). The new program was applied to elite speed skating athletes (four males and four females). To determine the improvement in starting technique, we recorded race images during the start phase of the 500-m race held in 2016 and 2017. The race images were collected using five high-speed cameras and kinematic characteristics of the start phase were analyzed by three-dimensional image analysis. Results: The 1RMs were improved by 11% on an average after the strength training. In 2017, records of four out of the eight athletes were shortened in terms of the initial lap time (100 m), and 500-m records were shortened in six athletes. The time to nine strokes was shortened in five athletes, and the ratio of correct kinetic chain was increased or maintained at a high level in six athletes. Conclusion: In this study, the new strength training program (2017), applied to elite speed skating athletes, showed a positive effect on starting technique and reduced the record times.

Background: Headaches arising from cervical musculoskeletal disorders are common. Conservative therapies are recommended as the choice of first treatment. Evidence to the effects of manual therapy is inconclusive and available only during the short term. There is no evidence to exercise, and no study has investigated the effect of combined therapies for cervicogenic headache. Methods: In this study, 30 participants who met the diagnostic criteria for cervicogenic headache were randomized into two groups: experimental group and control group. The experimental group was performed myofascial release (MFR), Mulligan technique and self stretching exercises. The control group was performed electrical therapy and self stretching exercises. Assessments were performed to 30 participants before and after 4 weeks therapy. The components of assessments were headache intensity(HI), headcahe duration (HD), neck pain (NP) and neck disability index (NDI). Results: After 4 weeks therapy, HI, HD, neck pain and NDI were significantly reduced in both groups (p<.01). The HI, HD, neck pain and NDI were significantly reduced in experimental group more than in the control group (p<.01). Conclusions: Manual therapy could reduce the symptoms of cervicogenic headache.

This paper presents upgraded equipment to assist a patient in rehabilitating of their knee-joint by themselves. A new automatic mechanism is suggested and developed in order to add functions for enforcing the leg muscles, which were absent in previous rehabilitation machines. Using the Pro-engineer software, we analyze the displacements and speeds of several moving points of the equipment during various planned exercises. In addition, an appropriate control panel for operation is developed. Three motors andthree motor drivers are used in a tilting part for the ankle joint, sliding guide part for the knee joint, and up-down moving part for the whole leg. Finally, various newly upgraded motions can be generated by controlling the three motors simultaneously. we show that by using this equipment, we can adjust the proper length of the equipment according to the user's height and the intensity of the rehabilitation exercise.

Purpose: Hypertension tends to increase after the age of 65. Proper hypertension management requires physical activities such as habitual activities and exercise. However. it is reported that many elders do not have regular physical activities. This study was to identify physical activity patterns and blood pressure according to physical activity in the elderly with hypertension. Methods: This study assessed physical activity frequency, amount, type during the latest one week, and blood pressure and BMI. The subjects were 53 elders aged over 65 years. Collected data were analyzed through descriptive statistics, $x^2-test$, and logistic regression analysis using SPSS 12.0. Results: It was found that most of the subjects had not been participating in regular physical activities. The most frequent physical activity patterns were walking and home activity at a low or moderate intensity. The elderly who met the normal hypertension and pre-hypertension criteria involved significantly more regular physical activities. Conclusion: This study suggested that regular participation in physical activities should be recommended for elders in order to optimize the state of their blood pressure.

This case report describes the effectiveness of cervical corrective exercises in a patient with cervical radiculopathy (CR) who experienced radicular pain, upper limb paresis, and limited functional activity. A 39-year-old male with cervical radiculopathy performed the cervical corrective exercises for reducing pain. Pain intensity, cervical posture, and active range of motion of cervical intersegmental spine motion were measured baseline, after 4 weeks, and after 8 weeks with self-reported questionnaire and radiographs. After 8 weeks of intervention, the patient demonstrated alleviated radicular symptoms, improved neck posture and active range of flexion and extension of the cervical intersegmental spine. Especially in the angle between the cervical vertebra 6 and 7, the angle was changed from $-4.69^{\circ}$ to $3.30^{\circ}$ during resting position after intervention. The present case indicates that the cervical corrective exercises might be a possible treatment to effectively reduce radicular symptoms, improve neck posture, and active cervical intersegmental motion for patient with CR.
