In today’s business world, there are two very important health issues that the employees in the service sector are faced with: Spinal disease, especially in the lower back, and carpal tunnel syndrome. These are well-known musculoskeletal disorders. To preserve the health of its employees and prevent professional illnesses, and to thus maximize their efficiency, companies must use knowledge from the field of ergonomics. This study aims to examine the work-related health problems that the workers in transportation companies are faced with. As a case study, a postal company from Serbia is considered, with particular attention paid to the counter clerks. The research was carried out in one branch of the postal operator. All six postal clerks working at the considered branch were subjects of the study. The workers were observed visually by the researchers and recorded while performing their job tasks. Based on the analysis of their movements and body positions, the evaluation of their level of risk exposure was determined using the Ergo Fellow software, specifically with five packages within this program (Rapid Upper Limb Assessment, Rapid Entire Body Assessment, Ovako working posture analysis system, Moore and Garg, and Suzanne Rodgers). As a result of the implemented tools, the analysts are in a position to conclude what should be changed in the work organization.

Background and aims: Nowadays, work-related musculoskeletal disorders are the most common occupational diseases. The prevention of these disorders requires a posture analysis during work and the improvement of working conditions. The purpose of this study was to determine risk factors for musculoskeletal disorders and corrective priorities to perform the work by conducting postures analysis using Rapid Entire Body Assessment (REBA). Methods: In this descriptive-analytical study, the posture of dentists during working was analyzed using the REBA software. The incidence rate of musculoskeletal disorders was investigated by the Nordic Musculoskeletal Questionnaire (NMQ). A P value less than 0.05 was considered statistically significant. Results: In this applied study, the incidence rates of the pain in neck, waist, shoulders, and wrists were reported to be 68%, 55%, 41% and 28%, respectively. The above-mentioned values were higher in women than in men. The pain in thigh and leg was related to work and the pain in ankle and sole was related to body mass index (BMI). The relationship between musculoskeletal disorders and occupational postures of dentists was statistically significant (P<0.05). Conclusion: Training the principles of ergonomics and anthropometrics, the correct methods and principles of performing work, and the ways of using the instruments are necessary for the studied population. Occupational postures require ergonomic intervention and correction.

This study aimed to systematically compare three representative observational methods for assessing musculoskeletal loadings and their association with musculoskeletal disorders (MSDs): Ovako Working Posture Analysis System (OWAS), Rapid Upper Limb Assessment (RULA), and Rapid Entire Body Assessment (REBA). The comparison was based on a literature review without time limitations and was conducted on various factors related to observational methods. The comparisons showed that although it has a significant limitation of comprising only two classifications for the leg postures, (1) the RULA is the most frequently used method among the three techniques; (2) many studies adopted the RULA even in evaluation of unstable lower limb postures; (3) the RULA assessed postural loads as higher risk levels in most studies reviewed in this research; (4) the intra- and inter-reliabilities for the RULA were not low; and (5) the risk levels assessed by the RULA were more significantly associated with postural load criteria such as discomfort, MHTs and % capable at the trunk, and MSDs.

 Tiga Hati Mutiara is a food industry located in Sukoharjao, Central Java. One of the activities in the production process is packaging. The posture of the workers in the packing process is to stand and bend over. The position of the worker is very dangerous if it is done repeatedly and continuously. This study aims to identify the posture and ergonomic risks of workers and provide suggestions for improving worker posture. The methods used in this research are the Rapid Entire Body Assessment (REBA) method and the Ovako Work Posture Analysis System (OWAS) method. The results of the research on the packaging process using the REBA method obtained a score of 8, which means that the level of risk is high and needs immediate improvement, while the OWAS method has a score of 4, which means that this attitude is very dangerous for the musculoskeletal system and needs immediate improvement. Improvements made are to improve the position of workers and dimensions of the table. After the improvement, the REBA score was 2 and OWAS was 1, which means that the proposed posture condition is good.

Background and purpose: Work-related musculoskeletal disorders usually entangle back spines, neck and upper limbs. Working as a barber paves the ground for probable high prevalence of musculoskeletal disorders. This study was designed to evaluate the working postures of sari male barbers by Rapid Entire Body Assessment method and determining the prevalence of musculoskeletal disorders using NORDIC questionnaire.Methods: In the present research, 108 Sari barbers working conditions were evaluated using Rapid Entire Body Assessment (REBA) tool, and the data on the prevalence of musculoskeletal disorders was collected using Nordic questionnaire. Microsoft Excel and SPSS were then applied to analyze the data. Quantitative variables were analyzed using the descriptive statistical methods including mean and standard deviation. Chi-square test and ordinal regression have also been applied to analyze the relationship between different variables and musculoskeletal disorders' prevalence.Results: The mean age the participants was 33.11±8.2 and the mean of work experience was 12±3.7 years. According to the results of the Nordic questionnaire, during 12 past months, 78% of the studied subjects have discovered pain and discomfort at least in one of their 9 body regions. Complaints of musculoskeletal pains in the wrist were also most prevalent (72.1%), followed by the neck (49%) and elbow pains (46.2%). Through REBA Method, the highest frequency of corrective measures was at level 2 (73.9%).Conclusion: The results of the present study indicated that the evaluated subjects working postures required correction.

BACKGROUND: The prevalence of musculoskeletal disorders is high among teachers. Poor posture when writing on whiteboards is considered among the important causes of these disorders. OBJECTIVE: The present study aimed to evaluate an electromechanical rolling whiteboard for educational environments as an ergonomic intervention. METHODS: Thirty university lecturers volunteered to take part in the study. Participants performed a 5-minute writing task on a regular board and on the newly modified whiteboard in random order. The comfort and effectiveness of the boards and the perceived physical effort and posture of the participants were evaluated and compared by applying the verbal rating scale, Borg’s rating of physical exertion scale, and rapid entire body assessment, respectively. RESULTS: A total of 83.2% of participants reported the new whiteboard to be comfortable or more comfortable to use than the regular whiteboard, and 76.6% of them found the new whiteboard to be higher or much higher in effectiveness and usefulness in comparison with the regular whiteboard. The comfort and posture ratings revealed that exertion was significantly less and posture improved while writing on the new board as compared to its counterpart (p < 0.0001). CONCLUSION: The new whiteboard increased user comfort, reduced physical effort, and improved posture, hopefully leading to a decreased number of work-related musculoskeletal disorders.
