Various tools and methods are available to assess the risk of musculoskeletal injuries in occupational settings, each considering different assessment criteria. While these methods have been previously studied, further comparative investigations are still needed.

This study aimed to assess the risk of musculoskeletal disorders (MSDs) in workers performing various tasks using different ergonomic and biomechanical risk assessment tools and to compare the outcomes of these tools.

This analytical and cross-sectional study was conducted in a sector of the SAIPA Automobile Part Manufacturing Factory in Iran. A total of 33 workers engaged in lifting, grinding, pushing, and lowering activities participated. Lifting activities involved handling parts weighing 36, 7.9, and 3.4 kg at three workstations. In total, six tasks were examined, and workers' discomfort levels were evaluated using the Cornell Musculoskeletal Discomfort Questionnaires (CMDQ). Fourteen biomechanical and ergonomic risk assessment tools were utilized and compared. Kendall's tau-b correlation coefficient and Cohen's kappa agreement coefficient were applied to determine relationships between different tools and to match the measurement of risk levels, respectively. Additionally, the mean and standard deviation of the data were calculated.

There was a high positive correlation between the outcomes of three biomechanical tools [3D static strength prediction program TM (3DSSPP), hand-calculation back compressive force (HCBCF), and JACK], with 3DSSPP and HCBCF being interchangeable for estimating lumbar spine loads. Ergonomic assessment tools showed a suitable correlation in assessing load-carrying tasks. Manual handling assessment charts (MAC) had perfect agreement with National Institute for Occupational Safety and Health (NIOSH), and SNOOK with Washington Industrial Safety and Health Act (WISHA). Among body posture evaluation methods, rapid upper limb assessment (RULA) and rapid entire body assessment (REBA) had the highest correlation. Lifting fatigue failure tool (LiFFT) correlated well with manual handling methods, and survival chance correlated better with body posture evaluation methods. Lowering activities were identified as the most hazardous.

Ease of use and accuracy are key considerations when selecting biomechanical risk assessment tools. Experienced assessors can effectively utilize JACK, 3DSSPP, and HCBCF. The MAC and NIOSH, as well as RULA and REBA tools, are interchangeable. Selecting appropriate tools requires consideration of their limitations and advantages.

Musculoskeletal Disorders (MSDs) are the most common work-related problem in many bakery workers in developing and industrialized countries. This study aimed to assess the rate and ergonomic risk factors of MSDs among traditional bread bakers in Hamadan. 

This cross-sectional descriptive-analytic study was conducted on 310 traditional bread bakers in Hamadan, Iran. The prevalence of MSDs was assessed using the Nordic Questionnaire (NQ), body map, and Visual Analogue Scale (VAS). Analysis of data was performed in SPSS (version 20) using Chi-square and independent T tests. 

The Mean and Standard Deviation (M±SD) of work experience, height, weight, Body Mass Index (BMI) and age were respectively, 4±6.82 (Year), 1.6±0.08 (M), 60±12.76 (kg), 24.65±4.70 and 43.5±12.60 (Year). The involved organs in baking consisted of the neck, shoulder, back, waist, elbow, arm, hand, thigh, knee, shin and ankle. The highest prevalence rates of pain in the studied workers referred to the middle back (N=38; %92.68), knees (N=33; %80.49), shoulders (N=13; %30.95), forearms (N=11; %26.19) and wrists (N=11; %26.19) respectively.The prevalence of MSDs correlated with BMI and work experience significantly (P ≤0.05).

As, this study revealed that the rate of musculoskeletal disorders in the different body regions of bread bakers were high, properinterventional preventive management are strongly recommended to be designed and impleneted to eliminate the disorders among this target group.

Recently, there has been an increasing attention in workplace health-related issues. The issue of MusculoSkeletal Disorders (MSDs) has obtained considerable critical attention. In this regard,work station has a pivotal role in prevention of MSDs. This study was conducted to assess Work-Related Musculoskeletal Disorders (WMSDs) among a sample of Iranian computer users.

Method and Instruments:

 A cross-sectional study was conducted on office computer users of a university in Tehran. The sample size of 435 people were randomly selected from the university employees. A standardized questionnaire was used to collect data. The data were analyzed using Spss.

The results revealed that the pain was frequently felt in the region of neck (64.4%), shoulder (60.9%) and wrist complaints (52.4%). The current study showed a high prevalence of MSDs among computer users. In addition, according to workstation questions, it was reported that there were no support device in for supporting lower back and arm in the workstation equipments.

Workstation is one of the essential factors for the prevention of occupational damages in MSDs. This study recommends that there is a need to investigate office equipments as a crucial element not only for promoting performance abalities, health, safety, and efficiency improving but also in reducing complaints and pain caused by MSDs.

Occupational injuries and work-related disabilities are among the most factors contributing to the creation of musculoskeletal disorders (MSDs) in industry. Improper workstation and poor posture increase fatigue load and, eventually, the appearance of MSDs. In addition to reducing physical strength, MSDs mitigate accuracy, augment the accidents, and reduce job productivity. Hence, the purpose of this research was to assess the risk factors for MSDs in electrical devices assembly workers utilizing Muscle Fatigue Assessment (MFA) and Novel Ergonomic Pos tural Assessment (NERPA).

This study was one cross-sectional descriptive study in the year … and was conducted in one electrical device manufacturing workshop in Khuzestan province along with 84 female workers. 13 jobs and 32 postures were selected in this workshop. Nordic Questionnaire was used to determine the frequency of MSDs. Then, the risk levels were specified in the studied individuals with the use of MFA and NERPA. The obtained data were analyzed in SPSS software version 16. The statistical methods applied in this study were mean, standard deviation, frequency, frequency percentage, t-test of two independent samples, and correlation coefficient assessment. Furthermore, the significance level of statistical tests was considered to be P<0.05.

Findings obtained from MFA exhibited that the right wrist and waist were with 66.7%, neck and right shoulder were with 60% of workers and NERPA method results mentioned that the right wrist with 67.3% and the waist with 65.4% and neck with 61.3% and the right shoulder with 60.8% were at “very high” level of corrective actions priority, which these actions must be taken immediately. Also, statistical results indicated that there was a significant correlation between the results of Nordic, MFA, and NERPA questionnaires (P<0.05).

Concerning the kind of activity and misuse of support, the highest percentage of risk was evident in the right wrist, waist, and neck. So, a proper design of workstation and implementation of managerial actions were proposed to minimize muscle fatigue. These two methods also had similarities. MFA method was preferred when it was required to assess all body parts. On the other hand, NERPA was applied to determine more details.

The organizational leadership style can be considered as an important psychosocial factor that may affect workers’ health, safety, and productivity. The current study aimed at investigating the relationship between organizational leadership style and musculoskeletal disorders (MSDs) among workers. The current descriptive, cross sectional study was conducted on 188 employees, including 10 leaders and 178 followers of an Iranian process industry. Nordic MSDs questionnaire (NMQ) and leadership style questionnaire (MLQ) were used as data collection tools. Statistical analysis was performed with SPSS version 19. Totally, 71.7% of the participants reported experiencing the symptoms of MSDs during the last 12 months. The highest prevalence of MSDs was in lower back (47.2%), shoulder (34.8%), and neck (32.4%), respectively. Statistical analysis revealed that the mean scores of transformational and laissez faire leadership styles in the two groups of with and without MSDs were significantly different. MSDs had high prevalence among workers of the studied process industry. Higher rate of MSDs was observed among the workers with higher scores of laissez faire leadership style. In contrast, the employees under transformational leadership style as the dominant management method, reported lower rate of MSDs complaints. As a conclusion, a relationship was observed between the leadership style and MSDs occurrence in the studied industry.

In today's world, Musculoskeletal Disorders (MSDs) with high prevalence in work settings are one of the most important occupational health issues. In addition, MSDs cause personal distress, decreased working capacity, and waste of time, work absenteeism, increased health care costs and economic losses. This study aimed to compare the prevalence rate of MSDs and their associated factors among farmers and workers in Agh Ghala.
Methods and Materials: This study was a cross-sectional study. The study population consisted of 300 patients (150 farmers and 150 workers) who were selected from Agh Ghala city in Golestan province. The data collection instrument was Nordic questionnaires. The data were analyzed using descriptive statistics and chi-square test in SPSS software version.
In this study, about 72% of the farmers (N = 108) and 83.33% of the workers (N = 125) were suffering from MSDs during the preceding year. The most common disorders were Lower Back Pain (LBP) 36.7% (N = 55) and 55.3% (N = 83) in farmers and workers respectively, followed by knee pain 25.3% (N = 38) and 36.7% (N = 57) in farmers and workers respectively. The chi-square test showed a significant relationship between the MSDs and age, level of education, and training in ergonomic principles (P Regarding the high prevalence rate of MSDs, it is necessary to organize training courses about professional ergonomic interventions in order to raise farmer's and worker's awareness and skills. These programs can be used to improve the health behsubsequentubsequently healthworkers, duefarmers and workers due to preventing from the occurrence of musculoskeletal disorders.

Musculoskeletal disorders have been devoted high percentage of occupational injuries and it is one of the leading causes of absence from work and disability. In this study we aimed to determine prevalence of musculoskeletal disorders and their risk factors and to evaluate exposure of musculoskeletal disorders risk factors by Rapid Upper Limb Assessment (RULA) Technique in a porclean manufacturing factory in south Khorasan province. This cross-sectional study was conducted among 100 selected female workers from the decoration unit of the porclean manufacturing factory. Data were collected using demographical and Nordic Musculoskeletal Disorders Questionnaire (NMQ) and RULA form. Statistical analyses were performed by chi-square and t tests and using SPSS، version 16. The level of significance was set at <5%. The mean of age and job tenure in subjects were 28. 6±14. 09 and 2. 53±1. 63 years، respectively. Prevalence rate of MSDs was 81. 0%. 38. 0% of individuals were at risk level 2 and also 62. 0% at risk level 3 of RULA. Despite that means of age and job tenure were low، but prevalence of MSDs was high among workers. Assessment of MSDs and RULA risk level relationship indicated that MSDs risk level in exposed subjects were higher than non-exposed individuals.

Manual material handling is identified as one of the musculoskeletal disorders risk factors. The aims of this study were to evaluate lifting activities by NIOSH equation and MAC method and the correlation of these two methods. Methods and Materials: This cross-sectional study was conducted in a rubber industry. Studied subjects were 136 male workers selected from various sections by proportional-to size sampling method. Data were collected using demographic and Nordic Musculoskeletal Disorders Questionnaire (NMQ). Lifting activities were evaluated by NIOSH equation and MAC method. Statistical analyses were performed using SPSS, version 16 and some tests such as Independent sample t test, Chi-square (χ2) and Bland-Atman test. The level of significance was set at <5%. The means of age and job tenure in subjects were 33.31±6.48 and 9.77±6.17 years, respectively. Prevalence of MSDs was 77.2%. The results revealed significant association between MSDs risk level evaluated by NIOSH and MAC methods and musculoskeletal disorders occurrence. The correlation of the two lifting activity evaluation methods was significant (p<0.05). Based on the findings of the present study, the evaluated risk level by the two evaluation methods and prevalence of MSDshad significant relationship. The correlation result indicated that MAC method can be used interchangeably with NIOSH equation for ergonomic evaluation of lifting activities.
