Abstract
Introduction: Different studies around the world have shown that Work-Related Musculoskeletal Disorders (WMSDs) are the causes of lost time, absenteeism, and disability. The purpose of this study was to investigate the prevalence rate of musculoskeletal disorders (WMSDs) and to evaluate their ergonomic risk factors and determine the effect of ergonomic intervention on awkward postures among workers of Saipa Diesel Truck manufacturing plants.
Methods: This interventional study (Before-after) was conducted on 130 workers of 2 largest truck-manufacturing plants in Iran. The prevalence rate of MSDs and ergonomic risk factors was assessed by valid and reliable translated Body Map Questionnaire (BM) and Quick Exposure Check (QEC) method, respectively.
Results: According to Body Map results, 87.5% of participants had MSDs at least in one of their eleven body regions during the previous year, before study. The highest prevalence rate of MSDs was observed in lower back (51.5%) and foot area (18.5%). Chi square test revealed that the prevalence rate of MSDs was higher among those with higher QEC risk level (P < 0.001). Results also indicated the significant effect of ergonomic interventions on reducing the prevalence rate of MSDs and QEC risk level (P < 0.001).
Conclusions: This study showed that the prevalence rate of MSDs and QEC risk levels among workers was significantly high. Therefore, it can be mentioned that the need for early ergonomic interventions is felt in all industrial units of these truck-manufacturing plants.

Abstract
Background: Attention to the workstations of the employees and their quality of work life has become increasingly important due to the increased competition in the organizations. The present study aimed to investigate the relationship between the ergonomic situation of the workstations and musculoskeletal disorders with the quality of work life and demographic variables in the administrative staff of the Tehran Municipality.
Methods: The present study was a descriptive and analytical one. The statistical population included a total of 600 persons, working in one of the regions in the Tehran Municipality. Of the 600 staff, a total of 255 were selected as the available sample group. The instruments consisted of the questionnaires, including the individual and occupational information, the Nordic questionnaire, the Walton Quality of work life, and the checklist of the ergonomic indices of the working environment for the administrative staff. In order to analyze the data, Student’s t-test and multiple regression analysis were used.
Results: In this study, the majority of the samples were females (56.9%) with a mean age of 33 years. A significant positive relationship was observed between all the ergonomic indices and the quality of work life. Significant correlations among the parameters such as age, education, sleeping at night, psychological conditions, musculoskeletal disorders of the neck, shoulder, and foot were observed simultaneously with the quality of work life. The quality of work life of an employee could be predicted through the musculoskeletal disorders and demographic variables but could not be predicted by the ergonomic indicators.
Conclusion: In this study, a relationship existed between the ergonomic condition of the workstations and musculoskeletal disorders with the quality of work life and demographic variables. Therefore, the physical condition and the quality of the work life of the employees would be positively affected by the improvement of the ergonomic condition of the workstations.

Abstract
Background: The working station has a major impact on the musculoskeletal disorders, therefore a considerable attention to working station staff is of importance. The aim of this study was to investigate the effect of working station on musculoskeletal disorders among administrative staff.
Methods: 30 administrative staff participated in this analytical descriptive study. Data was collected using Nordic Musculoskeletal Disorders Questionnaire (NMQ) in ergonomic design intervention of three working stations (sitting, standing-and-sitting, standing) before and after of intervention. Moreover, a t-test and multiple regression were used to analyze the data.
Results: The average (standard deviation) of the age and work record of 30 participating employees were 44.3 (5) and 20 (5) years, respectively. There was a significant correlation between the type of working station before and after the intervention, with the expression of musculoskeletal disorders (P=0.02). There was also a significant relationship between variables of musculoskeletal disorders in the shoulders, necks, waist and hands at different working stations. However, there was a significant relationship between age, work experience and BMI index with musculoskeletal disorders.
Conclusion: According to the results of this survey the best working station is a sitting-and-standing. Therefore, by changing the type of working stations, musculoskeletal discomfort of the employees will be reduced appropriately.

Abstract
Background: Inadequate lighting in the workplace can cause unconventional changes in the posture of office workers. Poor ergonomic conditions in the office cause inappropriate postures during work and increase pressure on the musculoskeletal system which can cause some disorders in long-term. In this study, the relationship between work environment lighting with the prevalence and severity of musculoskeletal pain among office workers has been investigated.
Methods: In this study, the intensity of local illumination at work surface and at the perpendicular surface (perpendicular surface to the work surface and at the height of workers eye), and intensity of general lighting was measured based on the standard of The Illuminating Engineering Society (IES) using the SEKONIC, C-7000 SpectroMaster. Also, to assess the prevalence and severity of pain of musculoskeletal disorders, a Nordic Questionnaire and a Body map index were used respectively. To assess the office work strain, Rapid Office Strain Assessment techniques (ROSA) were used. Data were analyzed by SPSS 21.
Results: The results showed that the average intensity of general lighting, local lighting at work surface and at the perpendicular surface were 30.6%, 33.9%, and 38.4% respectively, which is lower than required illumination intensity of Occupational Exposure Limits (OEL). The neck and waist had the highest prevalence of the musculoskeletal disorders among the workers. The highest frequency percentage of scores in the ROSA method was the score 5 (41.7%) which had a significant correlation with illumination intensity.
Conclusion: Illumination intensity can be considered as one of the important factors affecting posture in administrative staff. Therefore, the improvement of illumination intensity can decrease the severity of musculoskeletal pain and improve the body postures of the staff and, consequently, increase their comfort.

Abstract
Introduction: Musculoskeletal disorders are major problems among hospital staff. One of the most important reasons for these disorders are patient handling tasks and psychosocial stressors. The aim of this study was to investigate the risk of musculoskeletal disorders and psychosocial stressors caused by patients handling among nurse aids.
Materials & Methods: This cross-sectional study was carried out among 56 nurse aids of Fasa University of Medical Sciences in 2017. The data were collected via Nordic questionnaire, MAPO index checklist and job content questionnaire. Descriptive statistics were used to describe the variables and the Chi-square test for analyzing the data.
Results: The results showed that the highest prevalence of musculoskeletal disorders was in the lower back (71.4%) and the least in the thigh and neck area (46.4%). The results of MAPO index for risk of musculoskeletal disorders showed that 9 out of 12 sections (63.2%) were in the 2nd level. Also, the average score of the dimensions of the psychological job demands and the physical job demands are high and the average score of social support is low, which indicates high stress. Also, the physical job demands (P=0.035), social support (P=0.002) and job insecurity (P=0.001) were related to the levels of MAPO risks.
Conclusion: According to the findings of the study, the prevalence of lower back pain is high and nurse aids experience many psychosocial stressors in their job life. So the training of ergonomic principles and the use of auxiliary equipment during the transport of patients, as well as the reduction of stressors such as the psychological and physical job demand and the lack of social support and job insecurity by authorities, the risk of musculoskeletal disorders can be reduced.

Abstract
Background and Objectives: Designing workstations in accordance with anthropometric characteristics of employees can prevent awkward working postures and reduce the risk of such disorders. The present study aimed at investigating the anthropometric compatibility of workstations in a sewing company and its relationship with working postures.
Methods: This cross-sectional study was conducted in a sewing company located in Hamadan province, Iran. Working postures were assessed in standing and sitting workstations using REBA and NERPA techniques, respectively. Anthropometric dimensions were measured in accordance with ISO 7250 and anthropometric compatibility with workstation was investigated. Mann-Whitney test was used for assessing the relationship between anthropometric compatibility and working posture.
Results: A total of 205 employees with a mean age 31.29 years participated in this study. Working postures were mostly in an unacceptable condition and the need for ergonomic intervention was evident. In sitting workstation, there was no significant relationship between working postures and anthropometric compatibility in terms of seat depth, seat width, and backrest height. In contrast, anthropometric compatibility with seat height and desk height were significantly associated with working posture (P<0.05). In standing workstations, a significant relationship was observed between anthropometric compatibility and desk height (P<0.05).
Conclusion: Anthropometric incompatibility with workstation generally deteriorated the working postures. However, anthropometric compatibility with seat height and desk height were the ones with a significant relationship with working posture. Therefore, for redesigning workstations the seat height and desk height should be considered first.

Abstract
Objectives: Inappropriate sitting posture on bench can contribute to pain and musculoskeletal disorders in students. Hearing and vision disabilities may be the cause of inappropriate sitting postures among students. Therefore, the aim of the present study was to compare the risk of musculoskeletal disorders in normal and students with hearing abnormalities in Ilam city.
Methods: Twenty students with hearing abnormalities (case) and 40 students with normal hearing (control) from primary schools in Ilam city of both genders were randomly included in the study. The worst recorded sitting posture of students on the bench was evaluated by the RULA method. Digimizer software was used to survey the body angles of the students while sitting on the bench. The used for analyzing the obtained data in 95% confidence interval.
Results: The results of posture evaluation showed that there was a significant difference in rula scores between case and control groups (P = 0.001). Deviation from the natural angles of the body in the case groups was more than the control group (P < 0.001), which has a direct and significant relationship with the increased risk of musculoskeletal disorders.
Conclusion: Musculoskeletal disorders possibility incidence were more common in students with hearing abnormalities compared to typical students which was due to an increase in deviation from the natural angles of the body and inappropriate postures. Given the limitation of the sample size, the present study recommends further research with the same goal and encourages interventional studies to correct the posture of hard of hearing students.

Abstract
Objectives: Health workers are the frontline of the fight against Coronavirus. During the Pandemic, these jobs, which had a lot of referrals, were under high work pressure, that can increase the chances of suffering from musculoskeletal disorders and affect their working ability. Therefore, this study aimed to determine the relationship between work ability and the prevalence of musculoskeletal disorders in the staff of Saveh's comprehensive urban and rural health service centers during the Corona Pandemic in 2022.
Methods: In this cross-sectional study, 197 employees of comprehensive urban and rural health service centers in Saveh city were randomly selected. The prevalence of musculoskeletal disorders and working ability were evaluated by the developed Nordic questionnaire and WAI (Work Ability Index), respectively. Data analysis was done using Pearson correlation coefficient tests and Two-way logistic regression.
Results: The average working ability of employees was equal to 34.86 ± 7.61. The most common areas involved in musculoskeletal disorders were the back (63%), neck (30%) and knees (17.8%) with the frequency of 125, 63 and 39 people, respectively. The index of working ability on musculoskeletal disorders in hip and thigh, hand and wrist, neck and back areas was significant (P ≤ 0.05). Also, the working ability was lower in cases with a history of corona virus infection (P = 0.001).
Conclusion: Considering the effect of working ability on the prevalence of musculoskeletal disorders, it is suggested that during the COVID-19 epidemic, identification of factors affecting the reduction of work ability and the implementation of ergonomic interventions should be prioritized.
