Abstract The ergonomics and environment factors have been the main issue for the mining industry for many years,and their profiles are increasing. To ensure an ergonomics work environment, it is possible to requirea particular attention especially in this industry sector. Due to lack of ergonomics knowledge and lowawareness among engineers in the mining industry, this may lead to become the central issue in Malaysia.The aim of this study is to investigate the physical risk factor associated with work-related musculoskeletaldisorder (WMSDs) by using workplace ergonomics assessment (WERA) among workers in the miningindustry. Based on the investigation, the action level of the WERA is medium that stated that the tasksneed to be investigated further and it requires changes. All physical risk factors involved the five top bodyregions such as shoulder, wrist, back, neck and leg. These have been identified to have an associationWMSDs by previous researchers. There were eighteen subjects selected in this investigation study. Thosesubjects were chosen according to their job tasks. The results of the analysis were used to improve theprocess of work, design of the workstation and also improving the work posture to enhance the comfortlevel of operators. This study is crucial for the mining industry because there is a lack of information andresearch about the ergonomics issues in the industry. The overall finding indicated that the whole processof selected job tasks will contribute to musculoskeletal disorder either for a short or long time exposure.

Background: Work-related musculoskeletal disorders at the elbow are a common health problem, which highly impacts workers’ well-being and performance. Besides existing qualitative information, there is a clear lack of quantitative information of physical risk factors associated with specific disorders at the elbow (SDEs). Objective: To provide evidence-based quantitative measures of physical risk factors associated with SDEs. Methods: Studies were searched from 2007 to 2017 in Medline, EMBASE, and Cochrane Work. The identified risk factors were grouped in main- and sub-categories of exposure using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework for rating evidence. Results: 133 different risk-factor specifications were identified in 10/524 articles and were grouped into 5 main- and 16 sub-categories of exposure. The risk factors were significantly associated with lateral epicondylitis, medial epicondylitis, or ulnar neuropathy. Significant risk factors such as wrist angular velocity (5°/s, with increasing prevalence ratio of 0.10%/(°/s), or forearm supination (≥45° and ≥5% of time combined with forceful lifting) were found. Conclusions: This review delivers a categorization of work-related physical risk-factor specifications for SDEs with a special focus on quantitative measures, ranked for evidence. These results may build the base for developing risk assessment methods and prospective preventive measures.

Perceived Workload

Although physical factors are accepted as risks in the development of work related musculoskeletal disorders (WMSDs), psychosocial factors may explain some of the remaining differences in susceptibility to WMSDs. The following study examined the effects of two psychosocial factors, mental workload and time pressure, on typing performance, perceived workload, and key strike force while typing. The majority of the key strike force measures increased with increases in time pressure and mental workload. Perceived overall workload (as measured using SWAT) increased with mental workload and time pressure, and typing performance decreased. Additionally, gender, locus of control, and perceived stress level did not influence outcomes. Physical risk factors may be mediated by psychosocial factors to increase risk for WMSD development in the upper extremities. Therefore, both physical and psychosocial aspects of work environments should be considered when designing jobs and work tasks to prevent injuries and improve productivity.

Background: Improper work postures have been associated with many detrimental health outcomes including musculoskeletal disorders. Emerging evidence however suggests that some of these health concerns may be lessened by reducing sedentary behaviour at work. Musculoskeletal disorders have been ranked top among the most prevalent health problems relating directly to working conditions. Aim: This study was thus aimed at determining the prevalence of musculoskeletal disorder symptoms and their relationship with work posture among staff of the University of Port Harcourt in Rivers State, Nigeria. Materials and Methods: A descriptive, cross sectional design was used in conducting this study among academic and non-academic staff of the University of Port Harcourt. 256 study participants were involved in this study. They were selected using the multistage sampling technique. A self-administered semi-structured questionnaire was the study instrument. Collected data was transferred to the Microsoft Excel (2016) software for cleaning and coding. The Statistical Package for Social Science was used for analysis of the data. Descriptive and inferential statistics were computed and statistical significance was set at <0.05. Results: Majority 172 (54.3%) of the respondents had experienced musculoskeletal pain that involved the head, neck, back and other regions of their bodies. Also, a statistically significant association was found to exist between work posture and the occurrence of pelvic and perineal pain. Dynamic postures while working was found to offer a protective effect against the occurrence of thoracic and abdominal pain (O.R. = 0.88). Conclusion and Recommendations: Work-related musculoskeletal disorder symptoms were found to be prevalent in this study. The relationship between work postures and the identified symptoms among the staff was also established. It was recommended that health information on alternation between sitting and standing working postures be passed on to staff working in the study area as well as a redesigning of the work-stations of the staff to adopt ergonomic standards necessary for preventing the occurrence of work-related musculoskeletal disorders.

Awkward Posture

The majority of women workers were performing spinning, warping and finishing tasks in the power-loom industry; espousing an awkward posture. Work-related musculoskeletal disorders (WRMSDs) are most important problems related to the cyclic and challenging working awkward posture. This study focuses on identification of ergonomic physical risk factors caused because of awkward posture and explores its association with the prevalence of WRMSDs among the ladies staff from power-loom industry Solapur town, geographic area, India. The WRMSDs indications were known estimated and analyzed victimization the Nordic Musculoskeletal Questionnaire (NMQ) and Rapid Upper Limb Assessment (RULA). Statistical analysis of ANOVA was performed to search out significance between variables of anthropometry and job details to the departments. NMQ results disclosed that the very best rates of disorders were found within the upper Arm (60%) wrist (52%), neck (42%), and Trunk (64%) severally, and therefore the consequences of the RULA technique showed that the upmost level of risk within the region of upper Arm (risk level four) and within the Trunk (risk level three point five). In addition, the multivariate analysis proven that age and job expertise had a major correlation with the prevalence of MSDs (Table 1, if P < 0.05, significant). By trying the values of correlation coefficients, there's no huge distinction to perform video analysis for analysis of RULA or NMQ for locating pain in body regions.

Occupational ergonomists often use a variety of methods to identify jobs that are considered at high risk for the development of work-related musculoskeletal illnesses. The Strain Index (SI) and the Occupational Repetitive Actions (OCRA) Checklist are two popular upper limb risk assessment tools used in many industries, including the agro-food industry. Both methods are based on similar biomechanical, physiological and epidemiologic principles, but their approach to quantification and estimation of risk factor magnitude is quite different. The purpose of this study was to assess the inter-method reliability of SI and OCRA Checklist. Methods: Twenty-one jobs were video recorded in a Sardinian cheese manufacturing facility. Eight raters were recruited to assess job exposures to physical risk factors using the SI and OCRA Checklist. Inter-method reliability was characterized using proportion of overall agreement, Cohen’s kappa, and Spearman and Pearson correlations. Results: Strain Index and the OCRA Checklist assessments produced generally reliable results, classifying the risk of 35 of 42 (83%) job exposures similarly. Conclusions: The OCRA Checklist and SI risk assessments are reliable upper limb measures of physical work exposures. Both measures appear useful for assessing risk of upper limb disorders of work tasks in the agro-food industry. However, the SI is specific to disorders of the distal upper limb and perhaps most useful for assessing risk in work primarily involving the wrist and fingers. Whereas the OCRA Checklist, which includes an assessment of the shoulder, may be more appropriate for evaluating jobs that also require extended periods of reaching and shoulder activity.

The Relationship

The performance of workers is a very important factor that could affect the overall productivity result. In the industrial repetitive task, the performance of direct workers has a significant impact on the work productivity. In this kind of task, the work productivity loss is not only seen from time loss but also due to functional incapacity of the workers. The workers are present at work but functionally limited due to work-related musculoskeletal disorders (WMSDs). There are various studies which have reported on the effects of WMSDs on the work productivity, but few attempts have been made to investigate the relationship. This study aims to develop a conceptual model of work productivity associated with WMSDs as an aid to identify the relationship between the risks of WMSDs and the work productivity. The knowledge on the relationship is important to reduce the risk of WMSDs and at the same time can optimize the work productivity. A conceptual model of work productivity associated with WMSDs in the industrial repetitive task was developed based on the review on the existing models and theories. The factors involved in the model were discussed. The factors involved were work-related physical risk factors, muscle fatigue, work-related musculoskeletal disorders and work productivity.

Abstract Objective This study investigated associations between the co-existence of multiple types of work-related psychosocial and physical risk factors, and (1) obesity; (2) smoking; and (3) leisure-time physical inactivity. It also aimed to identify sociodemographic characteristics related to clustering of work-related risk factors and lifestyle factors. Methods Cross-sectional data on work-related risk factors (e.g., decision authority and repetitive movements) and lifestyle was measured using a standardized questionnaire among 52,563 Dutch workers in health care, services, manufacturing and public sector. Multiple-adjusted logistic regression models assessed associations between the co-existence of multiple types of psychosocial and physical risk factors and lifestyle factors. Additionally, logistic regression models related age, gender and educational level to clustering of risk factors and lifestyle factors. Results The co-existence of multiple types of work-related psychosocial risk factors was associated with higher odds of smoking and being physically inactive. For example, workers exposed to three psychosocial risk factors had a 1.55 times higher odds of being physically inactive (95%CI: 1.42–1.70) compared to unexposed workers. A higher number of physical risk factors was also significantly associated with higher odds of smoking and obesity. The co-existence of multiple types of physical risk factors was not associated with higher odds of physical inactivity. Clustering of work-related risk factors and at least one unhealthy lifestyle factor occurred in particular among workers with low educational level. Conclusions Results imply that interventions are needed that focus on workers with a low educational level and address work-related physical and psychosocial risk factors as well as lifestyle.
