Postural Analysis

Work posture analysis is crucial in observing and reducing work-related musculoskeletal symptoms in the workplace. However, in a developing country, new raters are commonly assigned to conduct postural analysis to save on cost. This study aims to observe the validity and inter-rater reliability (defined as the degree of agreement among different raters) among new raters of three different commonly used work posture analysis methods: Rapid Upper Limb Assessment (RULA), Rapid Entire Body Assessment (REBA), and Ovako Workload Assessment System (OWAS). Fifty industrial engineering students, divided into five groups, who received prior training about the use of the methods, participated voluntarily in this study by observing ten different working postures in five different industries: the tofu, military equipment manufacturing, automotive maintenance and service, cracker, and milk-processing industries. One ergonomics expert also observed the working postures. Validity was observed based on the correlation between new raters’ ratings and the rating of the ergonomics expert. Inter-rater reliability within one group was calculated using the percentage of agreement and kappa value. The result shows high validity of RULA, REBA, and OWAS among new raters. There are insignificant differences in the inter-rater reliability of new raters among RULA, REBA, and OWAS. The implications of the result are discussed.

Ergonomics integrates knowledge from the human sciences to match jobs, systems, products, and environments to the physical and mental abilities and limitations of people. Most of the injuries, stresses and strains in construction industry occur due to over-exertion and repetitive work actions. Postural analysis can be a powerful technique for assessing work activities. Use of ergonomic principles reduces fatigue experienced by the human body in various tasks. Ergonomics deals with the study of internal and external stresses acting on the human body. The aim of this study is to assess the level of ergonomics in various tasks in the construction industry .The study also aims to find the level of musculoskeletal disorders in workers and suggest corrective measures for every task having high risk factor. The study is conducted by using the Rapid Entire Body Assessment (REBA) tool of Ergofellow software, to assess the posture of workers in various construction tasks. Fatigue analysis is done by this method, which provides a scoring system for muscle activity caused by static, dynamic, rapid changing or unstable postures.

Pine resin is one of the non-timber forest products commodity that has excellent prospects. Pine resin harvesting is generally divided into two main activities: tapping and collecting works. Collecting activity that is commonly done under manual technique is classified as manual material handling that can trigger musculoskeletal disorders (MSDs). This work posture study offers an overview of MSDs disruption level faced by workers. Therefore, the proper corrective action can be taken. Motion sequences in selected work cycles were captured by using the Kinovea software. Work posture analysis was performed by a combination of the natural range of motion (SAG), Rapid Upper-Limb Assessment (RULA), and Rapid Entire Body Assessment (REBA). SAG analysis shows that the body’s parts having a high probability of being injured are the back and shoulders. Work posture analysis using RULA and REBA verified that bending or half bending may cause MSDs. The ergonomics risk in these positions might be higher due to the influence of load and repetitive factors. Reducing the posture of bending/half bending, reducing the weight of the resin bucket, and taking a short break/rest in between work activities should be considered as potential strategies in reducing the ergonomics risks that may occur during the resin collection work.  Keywords: forestry workers, musculoskeletal disorders, non-timber forest products, oleoresin, natural range of motion

The main aim of this cross-sectional study was to evaluate work-related injuries (WRI) and the self-reported musculoskeletal symptoms among 742 railway track maintainers. The second aim of this study was to investigate the potential factors related to the prevalence of musculoskeletal disorders (MSDs) in track maintainers. This study also tried to do planning and implementing ergonomic intervention programs to improve track maintainer’s health. Modified Nordic questionnaires were administered to assess the prevalence of MSDs. Detailed posture analysis by rapid entire body assessment (REBA) method was performed to assess the risk level of concerned postures. The injury data for 12 months were collected by conducting a survey and personal interviews with the affected railway track maintainers. To assess the prevalence of MSDs, the odds ratio and 95% confidence interval were computed along with critical χ 2 values. Analysis of variance was performed to determine significant differences between the MSD present and absent among the track maintainers of the Indian railway. The result of this study showed that neglect of safety precautions is the main reason for injury, followed by slipping and falling and lack of awareness. Sprain injury is one of the main injuries, followed by cut, snakebite, abrasion, and fracture. Low educational levels of workers are also reasons for WRI. In conclusion, the prevalence and severity of MSD, particularly in the low back, knees, wrist, and shoulder and WRI were found to be very high among the track maintainers. The recommendations of this research are ergonomic interventions, such as track maintainers proper training, following the National Institute of Occupational Safety and Health -recommended weight limit for manual material handling, modification in hand tools, job rotation, performing stretching exercise, and avoiding awkward and static posture are needed.
