An ergonomic focus evaluation of work-related musculoskeletal disorders amongst operators in the UAE network control centres

Work-related musculoskeletal disorders (WMSDs) have rapidly increased during the last decade, but only a few descriptive surveys have been conducted in the United Arab Emirates (UAE). This study investigated the prevalence of WMSDs and analysed their ergonomic risks amongst operators in the network control rooms across two government organisations, X and Y, in the UAE. Essential data were collected by the Nordic Musculoskeletal Questionnaire (NMQ) and the Maastricht Upper Extremity Questionnaire (MUEQ) from online surveys and direct observations based on the Rapid Office Strain Assessment (ROSA) and the Rapid Upper Limb Assessment (RULA) form and ergonomic measurements for the working environments, respectively. Fifty-three and eighteen operators participated from Organisations X and Y. This study found a high presence of WMSDs in both organisations over the past 12 months. In Organisation X, individual, work-related physical and psychosocial risk factors of high BMI, educational level, morning work shift, high job duration, lack of exercise habit, awkward body posture, high job demand, low job control, and low work social support were associated with WMSDs in different body areas (p < 0.05). In Organisation Y, older age, high BMI, high job duration, lack of exercise habits, unergonomic workstations, awkward body posture, low break time, high job demand, and stress level were associated with WMSDs in different body areas (p < 0.05). The control room operators' most affected body areas were the back, eyes, and neck. Several efficient ergonomic intervention ideas were explored to lessen the detrimental effects of WMSDs and preclude the development of WMSDs amongst the control centre operators.

Analisis Risiko Ergonomi Lingkungan Kerja Fisik pada Karyawan Kantor Menggunakan Metode Rapid Office Strain Assessment (ROSA)

The use of computers is now inseparable from office work completion activities. The place where routine business or commerce takes place is the office. Workers are required to spend nearly all of their time operating the computer while seated in front of the monitor due to the computerized system for office work. Long-term computer use combined with improper posture can result in eye fatigue as well as muscle and back injuries and fatigue. Work stances like sitting, composing, and gazing at a PC screen will influence the state of being of representatives. Employee performance will suffer as a result of poor ergonomic work postures, which will put employees at risk and make them more likely to become exhausted. Based on the rapid office strain assessment method, this study was conducted to determine the ergonomic risk analysis of the physical work environment in the work posture of office employees. The Rapid Office Strain Assessment (ROSA) analysis method was used in this observational descriptive study. A method for measuring ergonomic risk in the workplace at an office is the ROSA method. Perceptions were made to straightforwardly see the communication between work stances and office offices as office support components in 15 representatives who turned into the examination test. The findings revealed that 10 employees had a level of ergonomic risk that was low, while the remaining 5 employees had a level of ergonomic risk that was moderate. The reason for high ergonomic gamble lies in ergonomic offices that are not as per ergonomic standards and absence of representative mindfulness in making a solid work culture. Modernizing office facilities, spreading awareness of office ergonomics, and requiring employees to stretch are all necessary improvements.&#x0D; Keywords: Office Ergonomics, Ergonomic Risk, Rapid Office Strain Assessmentt, Work Posture

Ergonomics of E-Learning Workstations and the Prevalence of Musculoskeletal Disorders-Study among University Students.

The prevalence of musculoskeletal disorders (MSD) has increased significantly in recent years. The COVID-19 pandemic has led to a fundamental change in the lifestyles, ways of learning and working patterns of the general population, which in turn, might lead to health consequences. The aim of this study was to evaluate the conditions of e-learning and the impact of the learning modality on the occurrence of musculoskeletal symptoms among university students in Poland. This cross-sectional study included 914 students who completed an anonymous questionnaire. The questions covered two time periods (before and during the COVID-19 pandemic) and were aimed at obtaining information about lifestyle (including physical activity using the modified International Physical Activity Questionnaire, 2007 (IPAQ), perceived stress and sleep patterns), the ergonomics of computer workstations (by Rapid Office Strain Assessment, 2012 (ROSA) method), the incidence and severity of musculoskeletal symptoms (by the Nordic Musculoskeletal Questionnaire, 2018 (NMQ)) and headaches. The main differences between the two periods were statistically significant according to the Wilcoxon test in terms of physical activity, computer use time, and severity of headaches. During the COVID-19 pandemic, there was a significant increase in MSD (68.2% vs. 74.6%) and their intensity (2.83 ± 2.36 vs. 3.50 ± 2.79 points) among the student population (p < 0.001). In the group of students with MSD, there was a high musculoskeletal load, due to the lack of ergonomic remote learning workstations. In future, a thorough study should be carried out, and there is an urgent need to raise students' awareness of arranging learning workstations according to ergonomic principles in order to prevent the occurrence of musculoskeletal problems.

Health education using the theory of planned behavior to modify ergonomic posture in hospital computer users: a randomized controlled trial.

Work-related musculoskeletal disorders are prevalent in those who use computers, and education using ergonomic principles may be helpful to prevent such conditions. The present study sought to identify how an educational intervention based on the theory of planned behavior (TPB) may be effective for adopting healthy ergonomic postures. A convenience sample of 162 computer users working in a hospital setting in Iran were randomly assigned to intervention or control groups. The intervention group (n = 81) received six weekly educational sessions based on TPB principles, whereas the control group received no intervention during the study period. Both groups were assessed at baseline and 3 months after the intervention using a TPB questionnaire, rapid office strain assessment (ROSA), and Nordic musculoskeletal questionnaire. Data were analyzed using the independent/paired Student's t test, chi-square, and analysis of covariance. All TPB constructs in the intervention group improved from baseline to follow-up, indicating considerable progress compared to the control group (p < 0.001). More than 60% of intervention and control groups were categorized as high risk at baseline in terms of ergonomic posture measured by ROSA. This percentage was reduced to 21% for intervention group and increased to 65% in the control group at follow-up. Symptom relief was obtained for wrist/hands, lower back, neck, shoulders and upper back in the intervention group (all p < 0.05). The number of affected areas also significantly decreased in the intervention group compared to the control group three months after the intervention. Educational programs based on TPB principles may be helpful in correcting ergonomic postures among computer users. Such interventions are recommended for worksite health promotion in that they may prevent the development of musculoskeletal disorders in staff.
