PURPOSE: Low-intensity exercise with restriction of blood flow has been proposed as an alternative exercise to secure the disadvantage of a high-intensity resistance exercise. However, studies of how affects the muscle using functional exercise are lacking. Thus, the purpose of this study was to investigate knee extensor muscle strength during stair exercise of functional exercise with leg blood flow restriction. METHODS: Twenty two healthy young adults with no history of musculoskeletal or neurogical disorder were participated in this study. participant were randomized into either non-restriction group(11 subject) or restriction group (11 subject). The restriction blood cuff attached to the proximal end of the leg. Measurement of knee extensor strength was used by cybex dynamometer. Data analyzed in independent t-test and paired t-test. RESULTS: Knee extensor muscle strength was significantly different between groups. Also, there were significant differences in the strength of knee extensor within the group. CONCLUSION: This study found that stair exercise with restriction of blood flow did influence to knee extensor muscle strength. These results will also be able to promote the effect of increasing the muscle power applied to functional exercise. Henceforth, studies will be made in the intervention method that can be applied to health vulnerable person.

Objectives : The research was conducted for the use of HT1 in the shoulder disease through correct acupuncture. Methods : (1) The contents were compared through reviewing literature. (2) The literature was studied in conjunction with the shoulder pathology and anatomical structures. Results : (1) The location of HT1 is described as 'in the axilla, over the axillary artery' in many literature, and the depth of HT1 is as shallow as 1 cm. The WHO standard also follows this. (2) There were many references to 'in the axilla, between the big muscles' in later generations, but there were mixed opinions about the exact muscle names. Based on the acupunctural review and the musculoskeletal study, the big muscles are considered to be 'Pectoralis major' and 'Latissimus dorsi'. (3) Among the muscles constituting the rotator cuff, applying acupuncture on HT1 is essential for 'Subscapularis m.'. Therefore, it is effective to stimulate 'Subscapularis m.' to a depth of 1.5 to 4 cm. Conclusions : The accurate acupoint of HT1 enables various uses of flank, armpit, shoulder and arm diseases as well as cardiopathy. Especially, it helps to treat the muscles through safe and effective acupuncture in shoulder rotator cuff disorder.

Korean army dogs are raised for special purposes and have contributed much to society. However, several diseases occur in dogs. Canine hip dysplasia (CHD) is a musculoskeletal disorder that occurs frequently in Korean army dogs and interferes with their activities. If we could control CHD, this would have a positive effect on their performance. This study performed a genome-wide association study (GWAS) in 69 Korean army dogs to find significant loci for CHD using 170K single nucleotide polymorphisms (SNPs). CHD was classified according to the Norberg angle criterion. The control group comprised 62 dogs classified as relatively normal, and 7 dogs with severe CHD formed the case group. From the GWAS analysis, we concluded that SNPs present on chromosome 4 might have a significant impact on the overall expression of canine hip dysplasia.

The purpose of this study was to evaluate the biomechanical effect of sports taping on the lower limb during drop landing. Twelve male university students who have no musculoskeletal disorder were recruited as the subjects. Principal strain, median frequency, vertical GRF, loading rate, angular velocity and resultant joint moment were determined for each trial. For each dependent variable, paired t-test was performed to test if significant difference existed between taped and untaped conditions(p<.05). The results showed that principal strain of the thigh and the shank in taping group were significantly less than those found in control group. These indicated that sports taping may prevent excessive mechanical strain caused by impact force during the deceleration phase. Flexion(-)-extension(+) and varus(-)-valgus(+) resultant joint moment of the knee joint in taping group were greater than corresponding value for control group. It seems that extensor muscle of the knee joint were not only supported by sports taping during knee flexion but also sports taping is effective for minimizing the possibility of injury.

This study used both kinesiotaping and extracorporeal shock wave therapy on patients diagnosed with frozen shoulder - a common musculoskeletal disorder in adults - in order to observe the effects on the joint range of motion. 21 adult(male 12, female 9) were selected and distributed into randomized groups. One group received kinesiotaping (n=10) and the other group received kinesiotaping together with extracorporeal shockwave therapy (n=11). After a 6 week duration of receiving kinesiotaping and extracorporeal shockwave therapy, changes in the joint range of motion in the patients were observed. Post-treatment of frozen shoulder, the changes in abduction within the shoulder joint were as follows: in both groups there was a noticeable increase in the joint range of motion (p<.05). Post-treatment of frozen shoulder, the changes in external rotation within the shoulder joint were as follows: both groups showed a significant increase in the joint range of motion (p<.05). The result of suggest that, it can be inferred that both the extracorporeal shockwave therapy and kinesiotaping are effective in increasing the joint range of motion in patients with frozen shoulder.

Li-Fraumeni syndrome (LFS) is an autosomal dominant hereditary disorder characterised by a variety of different tumor types in children and young adults. That contains with a germline mutation in the tumor suppressor gene Tumor Protein p53 (TP53). That is extremely rare. Furthermore, this is sometimes overlooked. Here, we report a case of LFS which was confirmed by mutational analysis of the p53 gene. Also, literature review is intended to improve understanding of this disease entity.

Purpose: The purpose of this study was to compare the health status between foreign workers and native workers and to examine the influencing factors of health status of foreign and native workers. Methods: This was a secondary analysis of the data collected from the 3rd (2011) Korean Working Conditions Survey (KWCS). The sample included 101 foreign workers and 101 native workers matched by age and gender. Results: The difference in health status between foreign workers and native workers was not statistically significant. The most commonly complained health problem of foreign workers was muscle pain of the upper limbs. Among foreign workers, hazard exposure, coworker support and supervisor support were significant predictors of health status. Among native workers, income level and obesity were significant predictors of health status. Conclusion: For health management and health promotion of foreign workers, employers and health providers need to establish coworker supporting systems in workplace and improvement strategies of work environment. Particularly, they must pay closer attention to management of foreign workers' musculoskeletal disorder.

Purpose: This study analyzed the characteristics of occupational injuries and illnesses of the nursing staff to reveal the prevalence of the major diseases and the predominant causes of the injuries in the nursing environment. Methods: Total 3,455 work-related compensation cases of nursing staff from January 1 2000 to December 31 2012, were selected. The specific types of the diseases, injuries, causes and the time of the incidence were analyzed. Results: Majority of the compensated cases were young women under 30 years old. The composition of the occupational injuries and illness was 74.5% and 25.5%, respectively. Occupational infection was the major part of the occupational illnesses (47.3%), and 74% of them were tuberculosis. Musculoskeletal disorder (12.6%) was followed the infectious disease, and 36.4% of them occurred while moving the patients. Slipping was the most frequent injury; most of them resulted in the lower extremities injury. Most of the injuries increased during shift change, except workplace violence, which increased later than 19:00. Conclusion: Occupational injuries and illnesses of nursing staff need the specific prevention strategy, and the prevention strategy should be suitable for the nursing workplace.

Thirty healthy adults aged 20 to 29 with no history of musculoskeletal or neurogenic disorder volunteered for this study. The contract-relax with agonist contration(CRAC) was applied to the right hamstring muscles with the subject in the supine position. Each hamstring group was stretched on three sucessive days with several repetitions of the technique lasting 1min, 3min, and 5min. respectively. Hamstring extensibility at the knee(ROM) was measured before and after stretching using on electronic digital inclinometer(EDI). The results, namely the increase in ROM, were analysed using one-way repeated ANOVA at p<0.05. The differences were not significant. Possible factors influencing the results are excessive sensitibility of the measuring instrument, the psychological and physical status of the subjects, and the level of muscle fatigue. The mean increases in ROM were 3.0 at 1min., 2.6 at 3min, and 2.1 at 5min. Inclusion of a control group would have further defined the effects of the stretching technique.
