This study attempted to examine the impact of musculoskeletal pain on pedestrian crossing using a sample that consisted of 282 aged people. The research method involved an examination of the musculoskeletal pain of the elderly using a musculoskeletal questionnaire. The subjects were also told to walk across four- and six-lane pedestrian crossings while their gait velocity, step count, and step time were measured. The research results for pain by body regions indicated that waist pain had the highest complaint rate(33.3%). When there was musculoskeletal pain in the waist and leg/foot, gait velocity also decreased and step count and step time increased. However, usage of a cane turned out to have a positive impact on pedestrian crossing. Nevertheless, no significant relationship between waist and leg/foot pain and pedestrian crossing characteristics was found. We expect there will be continuous further studies on the subject of diverse physical problems of the aged and pedestrian crossing.

Purpose: This study examined the work-related musculoskeletal pain and quality of life of hospital workers. Methods: Self-reported questionnaires were sent to 350 hospital workers at Seoul and Gyeonggi-do, of which 341 were returned. The questionnaire had four items that covered the demographic information, areas of musculoskeletal problems, pain rating scale, and quality of life. The analysis was completed using descriptive statistic, and the differences between pain and demographic variables were identified using a chi-square test. The differences between the type of occupation and quality of life were analyzed by one-way analysis of variance and a Kruskal-Wallis test. Results: The 12-month prevalence of work-related musculoskeletal pain was 86.1% of physical therapists, 86.5% of occupational therapists, 77.1% of dental hygienists, and 75.8% of nurses. A significant difference in the general and work related variables was observed between the subject with a physical burden and type of occupation. The most affected pain sites of the physical therapist included low back, hand and wrist, shoulder, and neck. The occupational therapists included the hand and wrist, shoulder, neck, but the nurses and dental hygienists reported the shoulder, back, hand and wrist. A significant difference in the quality of life was noted between the subjects in physical therapists and dental hygienists and the subjects in the nurses and occupational therapists (p=0.00). Conclusion: These findings show that hospital workers appear to be high risk for work-related musculoskeletal pain, and the quality of life of physical therapists and nurses was higher than that of dental hygienists and occupational therapists.

PURPOSE: The aim of this study is to investigate the relationship between psychosocial factors and the severity of musculoskeletal pain in veterans with posttraumatic stress disorder (PTSD). METHODS: A total of 60 subjects were recruited from among the veterans with musculoskeletal pain at D Veterans Hospital. PTSD was evaluated by using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition; severity of pain was measured by using the short-form McGill Pain Questionnaire (SF-MPQ); depression and anxiety were measured by using the Symptom Checklist-90-Revision; and the quality of sleep was measured by using the Pittsburgh Sleep Quality Index. All data were analyzed using SPSS 18.0 software for Windows. RESULTS: The averages cores of pain intensity ($7.48{\pm}1.67$), SF-MPQ-sensory ($13.84{\pm}7.52$), SF-MPQ-affective ($4.41{\pm}3.79$), depression ($19.30{\pm}11.37$), anxiety ($13.39{\pm}7.99$), and quality of sleep ($10.05{\pm}5.89$) were obtained in veterans with PTSD. SF-MPQ-sensory measures sleep quality (r=0.346, p<0.01), SF-MPQ-affective measures depression (r=0.318, p<0.01) and anxiety (r=0.404, p<0.01), and these showed a statistically significant positive correlation in veterans with PTSD. Pain levels were observed to be higher in veterans with PTSD. Moreover, in these subjects, physical pain had a significant influence on the anxiety variable among the psychosocial factors. CONCLUSION: These findings suggest that musculoskeletal pain provides meaningful information about depression, anxiety, and sleep disorder in veterans with PTSD. Our data suggest that musculoskeletal pain may need to be addressed as part of the health management process of veterans.

The purpose of study is to identify the relation between pain level and perceived family support and quality of life in musculoskeletal patient with chronic pain. The subjects for the study consist of 155 patients with musculoskeletal pain that received medical treatment in hospital or by attending hospital in Chonju. The data were collected during the period from August 5 to August 14, 1998 by means of interviews with structured questionnaire. Data analysis was done by descriptive statistics. t-test, ANOVA, Pearson's correlation, Regression. Cronbach alpha using the SAS program. The result of this study were as follows : 1. The mean score of pain was 8.02, family support was 3.88 and quality of life was 3.07. 2. Hypothesis : The first hypothesis that 'The lower pain level is, the higher quality of life is' was accepted (r=-.2178, p= .0065). In addition, pain level of musculoskeletal patient with chronic pain provided predicted 4.7%(F=7.619, P= .0065) of quality of life. The second hypothesis that 'The higher perceived family support is, the lower pain level is' was rejected (r=-.0376, p= .6425). The third hypothesis that 'The higher perceived family support is, is higher quality of life is' was accepted (r= .3212, p= .0001). In addition, perceived family support of musculoskeletal patient with chronic pain provided predicted 10.31% (F=17.597, p= .0001) of quality of life. 3. General characteristics related pain were age(F=6.85, p= .0001),educational-level(F=9.29, p= .0001), occupation(F=5.81, p= .0037), marriage status(F=8.09, p= .0005), family numbers(F=5.73, p= .001), benefits of medical care(F=4.09, p= .0019), pain period(F=9.52, p= .0001), part of pain(F=2.33, p= .0352), pain period(F=3.08, p= .0181). 4. General characteristics related pain were sex(t=3.20, p= .0017), support sources(t=3.26, p= .0014), pain period(F-4.52, p= .0018). 5. General characteristics related pain were religion(t=3.11. p= .0022), benefits of medical care(F=3.61, p= .0293), pain duration(F=3.03, p= .0195). In conclusion, perceived family support in musculoskeletal patient with chronic pain is an important factor that can improve their quality of life. Therefore, nurses must establish nursing plan included patient's family when nurses carry out nursing intervention and education for patient so that a patient promote quality of life by maintaining optimal wellbeing.

This study examined emotional labor, fatigue, and musculoskeletal pain in hospital nurses. The study sample included 235 hospital nurses. The data were collected by questionnaire and analyzed with descriptive statistics, t-test, ANOVA, Scheffe test, Pearson's correlation coefficients, and multiple regression.The average emotional labor score was 3.27, and of fatigue was 2.04. The musculoskeletal pain score was 4.43. Emotional labor and fatigue are significantly positively associated with musculoskeletal pain(r=.180, p=.006; r=.278, p<.001). Emotional labor was positively associated with the degree of fatigue(r=.353, p<.001). The significant predictors of musculoskeletal pain for nurses were physical fatigue(${\beta}=.324$, p<.001) and gender(female)(${\beta}=.171$, p=.009), explaining 13.7% of the variance in musculoskeletal pain(F=16.271, p<.001). The results suggest that engaging in emotional labor related to nursing tasks increases the risks of fatigue and musculoskeletal pain. Therefore, it is important to develop a management program to relieve the emotional labor, fatigue, and prevent musculoskeletal pain for clinical nurses.

Objectives: The objectives of this study were to investigate female labor workers' occupational stress and musculoskeletal symptoms and to identify the effects of their occupational stress and musculoskeletal symptoms on their health-related quality of life. Methods: A survey was conducted through direct interviews using a musculoskeletal symptoms questionnaire, the Korean Occupational Stress Scale(KOSS), and the Short-Form 36-Item Health Survey(SF-36). Subjects were 112 female labor workers in three factories in D city who were selected by convenience sampling. Results: Factors significantly affecting health-related quality of life were found to be: occupational stress(${\beta}$=-.36); degree of pain, with medium pain(${\beta}$=-.31) and extremely severe pain(${\beta}$=-.24); duration of pain, with more than 1 week-less than 1 month(${\beta}$=-.25) and more than 6 months(${\beta}$=-.16); frequency of pain, with once per 2-3 months(${\beta}$=-.22); responses to pain such as medical leave, use of worker's compensation insurance, task change, etc.(${\beta}$=-.16), and Slightly difficult(${\beta}$=-.16) versus Not hard at all. These variables demonstrated that health-related quality of life is 48%(F=11.72, p<.001) in female workers. Conclusions: To improve female labor workers' health-related quality of life based on the above results, occupational health managers should reduce the workers' occupational stress, develop and apply health interventions regarding musculoskeletal symptoms, prevent the early onset of musculoskeletal symptoms, and protect and promote the workers' health.

In Korea, companies which have work-related musculoskeletal burden works should have conducted legal risk assessments every three years from 2004 onwards. However, due to problems with the legal definition of work-related musculoskeletal burden works, some companies may have been exempted from the risk assessment 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 legal musculoskeletal bueden works. However, this company eliminated the musculoskeletal burden works by continuously introducing automated processes, and finally, in 2016, all work which was legally defined as musculoskeletal burden work were 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 burden work. Therefore, this study proposes two improvements to solve these problems. Firstly, it is necessary to broaden the current legal definition of work-related musculoskeletal burden works. 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 musculoskeletal burden works. The results of this study could be used to improve the legal risk assessment of work-related musculoskeletal burden works.

Objectives : This study aimed to assess the effectiveness and safety of Taegeuk acupuncture for patients with chronic musculoskeletal pain. Methods : A retrospective analysis of the electronic medical records of Pusan National University Korean Medicine Hospital from March 2012 to March 2013 was performed. Eligible cases were outpatients who had received at least six sessions of Taegeuk acupuncture for their pain and had agreed to the use of their medical records for research purposes. Pain levels, heart rate variability, and patients' perceptions of the safety of acupuncture were investigated through the medical records and follow-up telephone interviews. Results : Fifteen cases were selected for analysis. All had suffered from musculoskeletal pain for at least one year. After six sessions of Taegeuk acupuncture, the average score on the pain numeric rating scale decreased from $6.7{\pm}2.0$ to $2.9{\pm}2.2$(a 43 % reduction). Follow-up telephone interviews revealed that patients experienced no adverse event after Taegeuk acupuncture. Conclusions : Patients with chronic musculoskeletal pain showed a reduction of more than half of the baseline pain after six sessions of Taegeuk acupuncture. However, the beneficial effects observed in this retrospective analysis should be interpreted with caution due to selection and recall bias. Further randomized controlled trials of Taegeuk acupuncture for chronic musculoskeletal pain are warranted.
