Abstract Objectives Varied work-related musculoskeletal disorders (WMSDs) claim rates were found between companies even when they were in the same sectors with similar sizes. This study aimed to (i) identify common risk factors for back, shoulder, hand/wrist, and knee WMSDs among manufacturing jobs, and (ii) characterize the biomechanical exposures in jobs and work organizational practices between high and low WMSD claim rate companies so that more focused, industry-specific intervention strategies may be developed. Methods Using historical workers’ compensation data, manufacturing companies were divided into two paired groups (low and high in the lower 25%ile and higher 75%ile, respectively). On-site job evaluations were conducted in 16 companies to determine job biomechanical risk levels. Management and workers’ representatives in 32 paired companies were interviewed to identify possible differences between management strategies and management/worker relationships. A total of 39 injured workers were also interviewed to gather information of self-reported injury causes and suggested preventive measures. Results Analyses of 432 job evaluations showed that more jobs had higher risk levels of prolonged standing and heavy lifting in the high back WMSD claim rate companies than the low claim rate ones. No high biomechanical risk factors were found to be associated with jobs in high shoulder claim rate companies. High repetition, pinch force, and Strain Index were associated with high hand/wrist WMSD claim rate companies. High work pace and job stress were common among high knee WMSD claim rate companies. There were no statistically significant differences for the organizational factors between high and low WMSD claim rate companies. Heavy lifting, fast work pace, high hand/wrist repetition, high hand force, and awkward shoulder postures were identified as major contributing factors by the injured workers. Conclusions High WMSD claim rate companies appeared to have more high biomechanical exposure jobs than low WMSD claim rate companies. Available job evaluation methods for the low back and hand/wrists are satisfactory in quantifying job risk levels in the manufacturing industry. Research into more sensitive job evaluation methods for the shoulder and knee are needed.

Survey Questionnaires

Office ergonomics has been emphasized in many industries and organizations. Health problems such as musculoskeletal disorders and repetitive syndrome injuries are commonly reported by office workers worldwide. The aim of this study is to evaluate the level of awareness and understanding of ergonomics among a local institute of higher learning office workers who use computers every day in their work. Secondly is to identify suitable ergonomics intervention programs for the workers. Survey questionnaires were developed as online survey and the link was emailed to all staff. However, questionnaire in hardcopies were also prepared and manually distributed to all the different departments in UPNM such as the Registrar, Bursary, HEPA, Library, Publisher, as well as Centres and Faculties. The number respondents were 50 out of 120 staffs and 62% of the respondents were female. Questionnaires were divided into sections to get information on the demographic background, to evaluate the level of awareness regarding ergonomics, to determine ergonomics trainings or exposures experienced, to investigate any problems related to health problems or discomfort and workstations as well as physiological and psychological complaints. The hyphothesis that the Universitys workers have very little knowledge regarding office ergonomics and yet some of them have already experience work-related musculoskeletal disorders was found to be true. The result shows that the current level of ergonomics awareness in UPNM could be considered as at the beginner level. Fifty six presents of the respondents in the first instance relate ergonomics to health, back pain and work-related injuries separately. More than 50% reported moderate pain and soreness at various parts of their body. Therefore, the next step of ergonomics intervention that could be introduced is to educate them through educational tools and expert talks.

This research concerns the workplace design methodology, involving digital human models, that prevents work-related musculoskeletal disorders (WMSDs). We propose an approach that, in conjunction with one of the classic WMSD risk assessment methods, allows one to simplify simulations in a three-dimensional digital environment. Two real-life workstations from a manufacturing industry were modelled in a 3D Studio Max environment by means of an Anthropos ErgoMax system. A number of simulations show that, for the examined cases, classic boundary mannequins’ approaches can be replaced by using 50th percentile of a population individual, with a minimal impact on the WMSD risk. Although, the finding might not be suitable in all situations, it should be considered, especially where compromise solutions are being sought due to other criteria.

Different Sources

Different sources can lead to modifications at a workstation such as external (out of control of the company) and internal (intended by the company) sources. Modifications from both source types could potentially influence the level of exposure of employees to different risk factors of work-related musculoskeletal disorders. The use of different ergonomic evaluation methods can help understand the influence of modifications at a workstation and whether they have a positive or negative impact. This is shown through an example from the fish processing industry.

Body Map

Manufacturing industries were considered among the sectors with the considerable level of lost work days due to work related musculoskeletal disorders. The aim of the study is to find out the different parts of body affected due to discomfort while operating machines in manufacturing industry. In this study work-related body-part discomfort was assessed in 51 male operators by using a body map and ranking procedure, while operating different types of machines viz, lathe, drilling and grinding machines. The study showed that out of 51 operator’s, 45 reported discomfort in shoulder and neck, 34 in lower back, 32 in upper back, 46 in arm, and 23of the operators reported discomfort in the leg. Correlations between the discomfort level and different postures at different working conditions were higher. Except at the start of the shift, operators felt musculoskeletal discomfort in various body parts throughout the shift, and were highest at the end of the shift. The middle age group operators reported higher levels of discomfort. Keywords: Discomfort; Injury; Pain; Body map; Discomfort assessment; Questionnaire; Musculoskeletal disorders.
