Purpose: To provide basic data for developing a musculoskeletal disease prevention program by measuring the body alignment status of manufacturing workers performing musculoskeletal-related work and identifying differences in body alignment status according to the area of ​​musculoskeletal subjective symptoms and general characteristics. Method: The study was conducted from December 1, 2022 to January 26, 2023 among 162 workers at a parts manufacturer located in G City. As for the survey tool, body alignment was measured using posture measurement and analysis equipment (Exbody9100, Korea), and the survey was conducted using a self-administered questionnaire. Data analysis was performed using SPSS 27.0, including frequency analysis, independent t-test, and ANOVA. Results: The complaint rate of musculoskeletal symptoms was 98.8%, and the comprehensive musculoskeletal index indicating body alignment was 29.00±10.456, which could predict body misalignment. Pain severity (F=2.889, p<.024), duration of pain once pain occurs (F=3.245, p<.005), number of pain occurrences (F=3.093, p<.007), pain pattern depending on movement(F=2.542, p<.022) There was a significant difference with body alignment status. Conclusion: This study confirmed the relationship between physical imbalance and musculoskeletal pain and predicted the risk of developing musculoskeletal diseases through analysis of workers' body alignment status. Therefore, when establishing preventive measures for musculoskeletal diseases, preventive measures that can maintain body balance should be established.

( Ali Kitis ),( Nihal Buker ),( Ayse Unal ),( Raziye Savkın ) 대한통증학회 2017 The Korean Journal of Pain Vol.30 No.3

Background: This study was planned to investigate the relationship between musculoskeletal problems, depression, and quality of life in students preparing for university entrance exams. Methods: A total of 180 students were included in the study, 104 were female (57.77%), and 76 were male (42.22%). Students were reached through the cram schools ("dershane") in Denizli. Musculoskeletal system problems, depression status, and quality of life were determined with the Musculoskeletal-Postural Discomfort Scale (MDS), Boratav Depression Screen Scale (Bordepta), and Short Form-36 (SF-36), respectively. Demographic data, daily study, and sleep duration were also recorded. Results: Students have moderate musculoskeletal discomfort. Musculoskeletal disorders and depressive symptoms are more observed in female students than male students (P = 0.000). The SF-36 results were significantly negatively correlated with the MDS and Bordepta scores. A significant positive correlation was found between musculoskeletal disorders and depression status (r = 0.351, P = 0.000). Sleep duration was negatively correlated with the MDS and Bordepta (r = -0.209, P = 0.005; r = -0.148, P = 0.047, respectively) and positively correlated with the SF-36 role limitation/emotional and social functioning subscales (r = 0.225, P = 0.002 and r = 0.191, P = 0.010 respectively). Conclusions: Musculoskeletal problems and depression status negatively affects general health status especially in female students who are preparing for university entrance examinations. Students should be informed about musculoskeletal problems by healthcare professionals and the study room, tables, and chairs should be arranged ergonomically. Further studies might be determined that why musculoskeletal disorders and depression status are more widely among female students. (Korean J Pain 2017; 30: 192-6)

임영태(Lim, Young-Tae),이용식(Lee, Young-Sik),권문석(Kwon, Moon-Seok) 한국체육과학회 2015 한국체육과학회지 Vol.24 No.3

The purpose of this study was to analyze effect of the 12 weeks horse back riding on a capacity for landing skill and strategy of lower extremity musculoskeletal during landing. Using kinematic kinetic data from 40(control group 20, exercise groupe 20) middle school students participating in this study, we computed the lower extremities joint angle, joint moment and joint absorbed energy. The results show no significant effect of 12 week horse back riding exercise and lower extremities joint angle at initial contact and range of motion on the joints during the landing. However, peak ankle, knee joint extensor moment and knee joint absorbed energy showed a significant effect of horse back riding exercise. Therefore horse riding excerse were related to the landing strategy of lower extremities musculoskeletal.

Anne Lovise Nordstoga,Paul Jarle Mork,Marius Steiro Fimland 대한직업환경의학회 2018 대한직업환경의학회지 Vol.30 No.-

Background: Various occupational inpatient rehabilitation programs are established in Norway. This study aimed to assess change in cardiorespiratory fitness, pain, anxiety, depression, and quality of life in persons on long-term sick leave due to musculoskeletal-, mental or unspecific disorders after participation in multicomponent inpatient occupational rehabilitation. Methods: Twenty-five women and five men (mean age 45.2 years, SD 6.7, range 30–57) volunteered to participate in the study. The participants attended either 8 or 17 full days of occupational multicomponent rehabilitation including physical exercise, cognitive behavioral therapy in the form of acceptance and commitment therapy (ACT), and development of a tailored plan for return to work. Cardiorespiratory fitness was assessed by the Åstrand/Ryhming cycle test at the start and end of rehabilitation program, and at one-year follow-up. Changes in somatic and mental health were measured by questionnaires up to 4 months after start of the program. Results: Linear mixed models showed that the maximal oxygen uptake increased by 1.1 mL°kg-1°min<SUP>− 1</SUP> during the rehabilitation program and by 3.7 mL°kg-1°min<SUP>− 1</SUP> at one-year follow-up. There were minor improvements in somatic and mental health, and quality of life. Conclusions: This study indicates that occupational inpatient multicomponent rehabilitation including physical exercise and ACT may promote a long-term increase in physical exercise that is sufficient to induce a significant increase in cardiorespiratory fitness. Trial registration: The current study is not registered, but is part of a larger trial registered at clinicaltrials.gov

중소규모 사업장에서 근골격계 증상의 고 위험군 선정과 운동프로그램의 효과

김보경,박정일,임현우,구정완,이강숙 大韓産業醫學會 2005 대한직업환경의학회지 Vol.17 No.1

목적: 중소규모사업장 근로자들의 근골격계증상을 실제적이며 효과적으로 관리하는 방안을 제시하기 위하여 중점관리대상자를 선별하고 근골격계 운동프로그램의 효과를 평가하고자 하였다. 방법: 문헌검색과 Delphi법에 의한 전문가의견을 종합하여 근골격계질환과 관련된 요인을 선정하고 785명을 대상으로 이들 요인들에 관한 설문조사(5점척도)를 실시하였으며, 증상이 있는 군(3점척도 이상)을 위험군으로, 위험군 중에서 작업특성관련요인과 일반특성관련요인이 함께 있는 군(평균이 3점척도이상)을 고 위험군으로 분류하여 중점관리대상자를 선별하였다. 저 위험군과 고 위험군을 대상으로 12주간 근골격계 운동프로그램을 실시 한후 증상 호소율의 변화를 비교, 분석하여 운동프로그램의 효과를 평가하였다. 결과: 근골격계질환 위험군은 전체대상자 785명 중, 454명(57.8%)이었으며 고 위험군은 121명 (15.4%)이었다. 저 위험군의 근골격계증상에 대한 위험요인의 다중로지스틱회귀분석 결과 유의한 위험용인은 성, 근골격계질환과 관현된 개인질병이었고, 고 위험군에서의 위험요인은 연령, 성, 근골격계질환과 관련된 개인질병 등이었다. 저 위험군을 대상을 12주간의 운동프로그램 실시한 후 대조군에서의 근골격계증상호소율은 유의한 변화가 없었으나 중재군에서는 근골격계증상 호소율이 신체부위 모두에서 유의하게 감소하였고, 고위험군을 대상으로 12주간의 운동프로그램을 실시한 결과 대조군에서 근골격계 증상호소율이 팔과 팔꿈치 부위에서 유의하게 증가한 반면 중재군에서는 허리부위에서 증상호소율이 유의하게 감소하였다. 결론: 이상의 결과를 종합하면 저 위험군에서는 운동프로그램이 근골격계증상 관리에 유의하게 기여하였으나 고 위험군에서 운동프로그램의 효과는 확인할 수 없었기 때문에 고 위험군에서의 근골격계 증상을 효과적으로 관리하기 위하여는 운동프로그램외의 다른 조치가 필요할 것으로 판단된다. Objectives: This study was conducted to provide data for the establishment of a practical and the effective exercise program for managing the musculoskeletal symptoms of workers who are employed in small and medium sized enterprises. Methods: The risk factors related to musculoskeletal disease management were chosen according to the relevant literatures, and were based on advise from experts on the Delphi method. Questionnaires on selected risk factors (with a 5-point Likert scale) were given to 785 subjects who worked in small and medium sized enterprises. The subjects were then classified in the risk group when they had the symptoms and recorded at least 3 points. From those subjects in the risk group, those who had both work-related factors and general characteristics factors (with an average of at least 3 points) were further classified as the high risk group. We performed a 12-week musculoskeletal exercise program for the low and high risk groups to analyze their changes in symptoms and complaints in order to estimate the effectiveness of the exercise program. Results: Out of 785 subjects, 454(57.8%) were in the risk group of musculoskeletal diseases and 121(15.4%) were in the high risk group. According to multiple logistic regression analysis of the factors for the musculoskeletal symptoms in the low risk group, the significant risk factors were sex and personal disease related with musculoskeletal disease, while the risk factors in the high risk group were age, sex, and personal disease related with musculoskeletal disease. After the I2-week exercise program was performed by the low risk group, the number of musculoskeletal symptom complaints in the control group did not significantly changed, whereas for the intervention group, the number of musculoskeletal symptom complaints significantly declined for all parts of the body. After the 12-week exercise program performed by the high risk group, the number of musculoskeletal symptom complaints in the control group was significantly enhanced for the arm and elbow parts. In the intervention group, the complaint rate for musculoskeletal symptoms significantly declined only for the low back. Conclusion: The musculoskeletal symptoms were significantly improved by the exercise program in the low risk group, but not in the high risk group. It is suggested that control measures on administrative and/or work related factors, in addition to the exercise program should be considered simultancously for the control of musculoskeletal symptoms in groups at high risk of musculoskeletal disease.

김영은,김한준,윤지영,이웅우,양희준,김종민,전범석 대한파킨슨병및이상운동질환학회 2018 Journal Of Movement Disorders Vol.11 No.3

Objective Musculoskeletal problems are more common in patients with Parkinson’s disease (PD) than in normal elderly, but the impact of musculoskeletal problems on health-related quality of life (HRQoL) in patients with PD is unknown. Methods Four hundred consecutive patients with PD were enrolled for the evaluation of musculoskeletal problems and HRQoL. HRQoL was assessed by the 36-Item Short Form Health Survey, which comprised physical health and mental health. Results Of the total patients, 265 patients had musculoskeletal problems, and 135 patients did not have musculoskeletal problems. Patients with musculoskeletal problems reported lower levels of HRQoL in terms of physical health than did patients without musculoskeletal problems (p < 0.05). In women, all components of physical health were lower in patients with musculoskeletal problems than in patients without musculoskeletal problems (p < 0.05). Meanwhile, in men, only the bodily pain score of physical health was lower in patients with musculoskeletal problems than in patients without musculoskeletal problems. Mental health and physical health were negatively correlated with depression, Unified Parkinson’s Disease Rating Scale I & II scores, and pain severity from musculoskeletal problems, in that order (p < 0.01 for all). Conclusion These results suggest that musculoskeletal problems in patients with PD affect HRQoL significantly, mainly in terms of physical health rather than mental health and especially in women rather than men. Musculoskeletal problems should not be overlooked in the care of patients with PD.

반도체 제조회사의 근골격계부담작업 유해요인조사 실태와 개선방안

정예영,박재희 한국안전학회 2022 한국안전학회지 Vol.37 No.1

In Korea, companies which perform work that places a burden on the musculoskeletal systems of their workers should have conducted legal risk assessments of this work every three years from 2004 onwards. However, due to problems with the legal definition of work-related musculoskeletal burdens, some companies may have been exempted from these risk assessments even though their workers still experience work-related musculoskeletal pain. For example, the manufacturing process used by a particular semiconductor manufacturing company involved a great deal of work which placed a burden on the musculoskeletal systems of its workers. However, this company eliminated the musculoskeletal burden on its workers by continuously introducing automated processes, and finally, in 2016, all work which was legally defined as placing a musculoskeletal burden on workers was removed from the company’s manufacturing process. Nevertheless, in a 2016 survey, 9.6% of the company's workers still complained of musculoskeletal pain, and in a 2019 survey this proportion actually increased to 15.7%. This incident demonstrates the limitations and problems of the current legal risk assessment of work-related musculoskeletal burdens. Therefore, this study proposes two improvements to solve these problems. Firstly, it is necessary to broaden the current legal definition of work-related musculoskeletal burdens. For example, vibration risk factors and push/pull tasks that are currently missing from the definition should be included. Secondly, it is proposed that a survey on musculoskeletal pain should be conducted for all workers, regardless of whether they are engaged in work which is currently defined as placing a musculoskeletal burden on them. The results of this study could be used to improve the legal risk assessment of work-related musculoskeletal burdens.

근골격계부담작업의 적절성에 관한 연구

천인애(Inae Chun),김유창(Yuchang Kim) 대한인간공학회 2020 大韓人間工學會誌 Vol.39 No.5

Objective: The purpose of this study was to identify the problems and appropriateness of musculoskeletal burden work by industry, and to present the improvement direction and efficient implementation so that musculoskeletal burden work can be applied to the workplace. Background: The Ministry of Employment and Labor defined the scope of 11 musculoskeletal burden work in 2003. However, controversy continues over the appropriateness of musculoskeletal burden work. There are missing elements such as vibration, job stress, and a subjective load of workers in determining whether musculoskeletal burden work. Also, intermittent work with less than 60 days of work is not included in the musculoskeletal burden work. Method: This study was conducted a questionnaire of 127 safety manager, health manager, general worker, and administrative supervisor. Of the 127 respondents, 33.1% respondents were engaged in the manufacturing industry and 66.9% were engaged in the non-manufacturing industry. The main contents of the questionnaire are appropriateness and improvement direction of the 11 musculoskeletal burden work. Results: The results of the appropriateness of including a subjective load of workers to the evaluation method of musculoskeletal burden work were statistically significant differences by industry. The results of the appropriateness of the 11 musculoskeletal burden work were not statistically significant differences by industry except for No. 4, and 48.6% of respondents replied that the 11 musculoskeletal burden work were not appropriate. Conclusion: The 11 musculoskeletal burden work should be improved to include factors that can cause musculoskeletal disorders such as vibration and job stress. The intermittent criteria of musculoskeletal burden work need to be improved. In addition, by integrating musculoskeletal burden work No. 8 to 10 related to weight handling, it seems necessary to judge the degree of burden on a simple and clear criterion. Application: A subdivided criteria is needed so that the criteria for determining musculoskeletal burden work can be applied to various industries. The result of this study can be used as the basic data for research on the improvement of musculoskeletal burden work.

목적: 본 연구는 콜센터 상담원들의 전반적인 근골격계 자각 증상호소율과 직무스트레스 수준을 파악하고,사회 경제적 및 작업관련 요인,그리고 직무 스트레스요인 및 우울과 근골격계 유증상 위험의 관련성을 확인하고‘ 궁극적으로 콜센터상담원들의 근골격계 질환 관리에 있어서 집중적 관리를 해야 할 위험군을 선정하여 효과적인 보건 관리에 근거를 제시하는 것을 목적으로 하였다. 방법: 설문을 기반으로 한 단면 연구로서 연구대상자의 사회경제적 특성,직무스트레스 요인, 우울 증상,근골격 계 자각증상 등에 대해서 설문을 하여 근골격계 증상과의 연관성을 파악하였다. 근골격계 질환의 자각 증상에 따라 목,어깨,팔,손목‘허리,하지 한 군데라도 증상이 있 는 경우를 근골 증상군으로 정의하여 스트레스 요인 수준의 비차비를 추정하였다. 결과: 총 352명의 단변조사 결과 중 311명 (96.3%)의 자료틀 분석하였고, 311명 중 167명(53.7%)이 근골 증상군으로 분류되었다. 카이자승 검정에서 직무스트레스 총점과 불리환경,직무요구‘관계갈등에서의 고위험군 및 우울 증상군이 근골격계 증상을 보다 많이 호소하는 경향을 보였다.‘스트레스 요인의 비차비는 사회인구학적 특성과 직무관련 특성 및 우울에 대해 보정하였으며 스트레스 요인 중 물리적 환경만이 저위험군에 비하여 고위험군의 근골격계 증상에 대한 비차비가 증가함을 관찰하였다. 우울의 근골격계 증상에 대한 비차비는 사회인구학적 특성과 직무관련 특성 및 모든 스트레스 요인에 대해 보정하였으며 고위험군에서 비차비가 증가함을 관찰 하였다. 그 외의 스트레스요인에서는 근골격계 증상과의 통계적인 유의성을 찾을 수 없었다. 결론: 사회심리적 요인 중 물리환경과 우울에서 위험군은 정상군에 비하여 근골격계 증상에 대한 위험을 증가시킬 가능성이 있는 것으로 조사되었다. Objectives: An era of deindustrialization has begun in Korea after the industrial development that occurred up until the 1990's. Post industrialization dictates the development of the service industry and information technology with the associated musculoskeletal disorders in such industries. The association between musculoskeletal symptoms and psychosocial factors has been investigated by several researchers. The aims of this study was to characterize the relationship between musculoskeletal symptoms and psychosocial factors including occupational stress and depressive symptoms, and to provide basic data to group health practices for the prevention of musculoskeletal symptoms in the service industry. Methods: Musculoskeletal symptoms, depressive symptoms and occupational stress were surveyed in 311 female call center employees. The prevalence of musculoskeletal symptoms, depressive symptoms and occupational stress scores were assessed. The odds ratio of the high risk occupational stress group into musculoskeletal symptom group was assessed in an effort to determine the associations between occupational stress and musculoskeletal symptoms. Results: The overall prevalence of musculoskeletal and depressive symptoms was 53.7% and 20.6% respectively. The high risk occupational stress group of the total scores (p=0.049), physical environment (p=0.022),job demand (P=0.014) and interpersonal conflict (P=0.032) to musculoskeletal symptom were significant. The depression group was also significant (P=0.015). The adjusted odds ratio of the high risk stress group into the musculoskeletal symptom group inclusion was 1.687 (95% CI; 1.014∼2.808)for the physical environment, and 1.948 (95% CI; 1.031-3.683) for depression. Conclusions: Overall, the relationship between musculoskeletal symptom and the psychosocial factors was not significant. Only the physical environmental stress factor and depression showed marginal significance, which suggests the possibility of an increased risk of musculoskeletal symptoms. However, since the group in this study was a homogeneous occupational population, further study with a reference group will be needed.
