Abstract
Objectives: Musculoskeletal disorders (MSDs) are widespread and important health and social problems in industrialised society, reducing productivity, increasing treatment costs and affecting the quality of life of workers. The present study was conducted with the aim of investigating the effects of workload, fatigue, sleep quality and physical condition on musculoskeletal disorders among workers in the steel industry.
Methods: The present study is a descriptive and analytical study conducted on a population of 540 workers working in the steel industry in the city of Dezful. Based on simple random sampling, 400 people were selected as samples. The instruments used in this study are the Demographic Information Questionnaire, the Cornell Musculoskeletal Disorders Questionnaire (CMDQ), the Swedish Occupational Fatigue Inventory(SOFI), the Pittsburgh Sleep Quality (PSQI) and the NASA-TLX workload index. The Rapid Entire Body Assessment (REBA) was used. Descriptive statistical indices were used to analyze the data, and the relationships between observed and hidden variables were examined using structural equation modeling (SEM) The data were analyzed at a significance level of 0.05 and in SPSS software version 25.
Results: According to the prevalence of musculoskeletal disorders, back pain ranked first with a mean and standard deviation of 52.39±25.44 and knee pain ranked second with a mean and standard deviation of 46.46±26.45, indicating that the prevalence of these disorders is high among steel industry workers. The results of the correlation analysis showed that there is a positive and significant relationship between workload, fatigue, sleep quality and body condition and musculoskeletal disorders (p<0.05). The RMSEA index of less than 0.1 shows that the model proposed in this study fits well and demonstrates the role of workload variables, fatigue, sleep quality and body position in the direct and indirect causation of musculoskeletal disorders.
Conclusion: The results of this study show that improving workplace ergonomics, reducing workload and fatigue, and improving sleep quality can reduce the likelihood of musculoskeletal disorders in workers.

Abstract
Objectives: Pre-hospital emergency workers who are responsible for providing essential pre-hospital medical services are exposed to physical and mental disorders. Since musculoskeletal disorders can be affected by work-related stress and fatigue, the present study aimed to assess the relationship of work-related stress and fatigue with the prevalence of musculoskeletal disorders in pre-hospital emergency workers in Saveh.
Methods: This descriptive-analytical cross-sectional study was conducted in 2023. A total of 88 personnel of urban and road pre-hospital emergency centers in Saveh were included in the study by the census method. Data collection tools were the Health and Safety Executive (HSE), Multidimensional Fatigue Inventory (MFI-20, and Nordic Musculoskeletal Questionnaire. Data were analyzed in SPSS software (version 22) using independent t-tests, analysis of variance, Poisson regression, and Pearson correlation coefficients.
Results: The most common areas involved in musculoskeletal disorders were back (34.1%; n=30), neck (19.3%; n=17), and upper back (19.3%; n=17). Moreover, mean scores of work-related stress and work fatigue were 113.52±4.09 and 62.95±5.06, respectively. Musculoskeletal disorders showed a significant relationship with marital status, workplace, age, work experience, and number of working hours (P≤0.05). Nonetheless, there was no significant relationship between work-related stress and work fatigue (P=0.28), musculoskeletal disorders and work-related stress (P=0.93), as well as musculoskeletal disorders and work fatigue (P=0.44).
Conclusion: The prevalence of skeletal-muscular disorders was relatively high, and considering that these disorders are more frequently observed in married people and those who work on the road, training should be provided to these workers according to their place of work. The risk of developing skeletal-muscular disorders increases with age and work experience. Therefore, it is necessary to take precautions in this regard. Furthermore, since skeletal-muscular disorders increase with an increase in working hours, it is necessary to adjust working hours and avoid long shifts.

Abstract
Objectives: Musculoskeletal disorders are among the common problems in most work environments and work ability is considered a factor affecting the performance and productivity of employees. In the present study, the status of these two components and their relationship with each other in the staff working in the operating room were investigated.
Methods: The current cross-sectional study was conducted in the winter of 2023. In this research, 96 employees working in the operating rooms of government hospitals in Hamadan, Iran were enrolled by census sampling method based on the inclusion criteria. The data were collected through the Nordic standard questionnaire and the work ability index questionnaire. The collected data were analyzed in SPSS software (version 24) at two levels of descriptive (frequency, mean, and standard deviation) and inferential (t-test) statistics.
Results: In this study, 4 (4.2%) of the participants had one musculoskeletal disorder and the remaining 91 personnel (95.8%) had more than one disorder in their musculoskeletal systems. Average work ability index was 42.3±04.91. The results of the independent t-test showed that the work ability index among people with pain in the neck (P=0.003), shoulders (P=0.001), elbows (P=0.038), back (P=0.011), knees (P=0.001), and legs (P=0.002) were less than those without pain in these organs.
Conclusion: Results indicated the need to pay more attention to the implementation of ergonomic work environment and management interventions to reduce the prevalence of musculoskeletal disorders and thereby increase the efficiency and effectiveness of personnel.

Abstract
Objectives: Musculoskeletal disorders are among the health challenges for faculty members, affecting their performance and work-related quality of life. The present study aimed to investigate the relationship between these disorders and the ergonomic features of their workstations.
Methods: This research was conducted among 22 faculty members after obtaining informed consent and using a census method. The prevalence of disorders was assessed using the Cornell questionnaire, and the evaluation of the workstation was performed using the Rapid Office Strain Assessment (ROSA) method. Then, 14 anthropometric dimensions (differentiated by gender) were measured, and 13 workstation characteristics were assessed. Finally, 11 criteria were used for anthropometric fitness evaluation. Moreover, data analysis was carried out using SPSS software (version 26).
Results: Approximately 46% of the participants had experienced pain and discomfort in one of the musculoskeletal areas, with the wrist, neck, shoulder, and lower back being the most affected areas, respectively. The ROSA results indicated that 22.73% of the participants' workstations required ergonomic improvements. The most significant mismatches were found in the criteria of 1) trunk length-chair backrest length, 2) thigh thickness in a seated position-distance between thighs and desk, and 3) shoulder width-chair seat width.
Conclusion: The signs of a connection between the high prevalence of musculoskeletal disorders and the lack of anthropometric compatibility/inadequate knowledge among faculty members in the field of ergonomics were observed. This issue underscores the importance of considering ergonomic/anthropometric characteristics of office desks and chairs during the procurement of office supplies and emphasizes the need to enhance ergonomics knowledge.

Abstract
Objectives: In the last decade in Iran, the highest prevalence of musculoskeletal pain and discomfort among office workers has been reported in the neck, back, and shoulder areas. The present study aimed to assess the impact of ergonomic interventions in knowledge-based companies on musculoskeletal disorders, work-related stress, and quality of work life.
Methods: In this quasi-randomized controlled trial study, the participants, including 311 office workers, received ergonomic interventions at both individual and managerial levels.
Results: The implementation of individual ergonomic training interventions significantly reduced disorders in the neck, right and left shoulders, right forearm, and right wrist. Social support also demonstrated a significant increase in all three intervention groups. The interventions had a significant impact on the quality of working life. The changes in the mean quality of working life for the second and third groups in the first month of growth were significant and then continued similar to the trend of the control group.
Conclusion: The implementation of individual ergonomic training interventions significantly reduced musculoskeletal disorders in the neck, shoulders, and upper limbs. Nonetheless, management training interventions did not affect the musculoskeletal disorders of employees. Furthermore, concurrent implementation of individual ergonomics and management interventions exerted a more pronounced effect on the reduction of disorders. The implementation of management educational interventions and combined interventions led to a marked increase in the level of control experienced by participants, while both types of social support interventions also increased. The implementation of a multi-component ergonomics intervention program was demonstrated to enhance the impact of interventions on employees' health and productivity.

Abstract
Background and Objectives: Considering that working with electronic education equipment increased significantly during the Covid-19 era, the purpose of this research was to investigate the association of complaints of musculoskeletal disorders with the use of electronic equipment during virtual education
Methods: This cross-sectional study was conducted among a group of students in the first 4 years of Babol University of Medical Sciences, whose courses were mostly presented in virtual form. Data collection tools included personal information form and standard Nordic questionnaire. Data analyzed using descriptive and inferential statistical indicators, including Chi-square statistical test. Significance level were considered 0.05.
Results: The data obtained from 318 medical sciences students showed that 83.6% of them complained of pain in the musculoskeletal system during the past year. More than 21% of them had to take medicine, 19.9% needed to see a doctor and 4.1% had to use physiotherapy services. The results also showed that the amount of complaints of pain and discomfort in the musculoskeletal system during the last week and one year has a direct and statistically significant relationship with the amount of use of virtual education equipment (P ≤ 0.001).
Conclusion: The expansion of virtual education in universities and through it, the long and continuous use of electronic educational equipment can be effective in increasing the number of complaints of musculoskeletal disorders among medical sciences students. Although, lack of regular physical activity, smoking, high level of stress, insomnia and fatigue among medical students were also known as other effective factors.
