Association between body composition parameters and non-specific low back pain in sedentary workers
Wondeuk Kim,Dongchun Park,Doochul Shin 물리치료재활과학회 2021 Physical therapy rehabilitation science Vol.10 No.1
Objective: In clinical practice, there are a lot of exercise to reduce body weight or reduce the amount of body fat in order to solve back pain. However, many studies have contradicted the relationship between back pain and weight or body fat mass. The purpose of this study was to investigate the relationship between fat mass, body mass index and low back pain of office worker. Design: Crossed-sectional study Methods: Among the white-collar workers diagnosed with non-specific back pain by doctors, subjects who were not included in the exclusion criteria were selected to measure the subject s body fat mass, body mass index, pain intensity, and disability index due to back pain. The NPRS was used for the intensity of back pain of office workers, and the ODI was used for the degree of disability due to back pain. A body composition analyzer was used to measure the body fat mass and body mass index of white-collar workers. Results: There was no significant difference between the two groups in the comparison between the normal group and the excessive group according to the criteria of fat mass and body mass index. In the correlation analysis of fat mass, body mass index, pain intensity, and disability index, it was found that there was a significant correlation between fat mass and body mass index. However, neither fat mass nor body mass index had a significant correlation with pain intensity and disability index. Conclusions: The fat mass and body mass index of office worker do not affect low back pain.

Objective: Low back pain easily becomes chronic and has a high recurrence rate. Therefore, it is most important to preventchronicity and reduce the risk of recurrence in the early stages of back pain or at the stage with mild pain. Therefore, this study was conducted to compare hip joint muscle strength, trunk muscle endurance, and pelvic alignment between subjects with mild lowback pain and subjects without back pain. Design: Crossed-sectional studyMethods: The study was conducted by recruiting 30 students in their twenties who are enrolled in K University in Gyeongsangnam-do,and classifying them into 15 patients with mild back pain and 15 patients with normal. The subjects who participated in theexperiment were measured for hip flexor and extensor muscle strength, trunk flexion and extension muscle endurance, and pelvicalignment. To measure hip joint muscle strength, biodex was used, and muscle endurance of the trunk was recorded at the endrange of the trunk flexion and extension. And pelvic alignment was measured using Formetric 4D. Results: There were no significant differences in hip joint muscle strength, pelvic alignment, and trunk extension muscleendurance. The retention time was found to be significantly shorter in the mild low back pain group than in the normal group fortrunk flexion muscle endurance. Conclusions: In the early stages of back pain or in the mild pain stage, training to increase muscle endurance of the flexor musclesmay be helpful.
An Interactive Effect of Power Parity and Dissatisfaction on Great Power Wars from 1494 to 1993

The purpose of this research is twofold. First of all, this study is designed to empirically test the relationship between great power war and the change of power distribution in the world system from the Italian Wars (1494) to the Post Cold War (1993). Second, this study demonstrates that in the power transition framework, the interactive variable of power parity and dissatisfaction is the most important explanatory variable. The results of this empirical analysis support the main argument of the power transition theory - when a dissatisfied but rapidly growing challenger catches up with the declining dominant power in national capabilities after taking into effect, war between them is highly likely.
