Abstract

Introduction: Work-related musculoskeletal disorders (WMSDs) are the most common occupational health problems, reported with high costs and loss of productivity in nurses. On one hand, the quality of life is a multidimensional concept that affects factors such as physical and psychological ones. This study aimed to evaluate the relationship between WMSDs and quality of life in nurses.

Methods: This descriptive-analytical study was performed on 940 nursing staff in Hospitals of Sari, Iran. The samples were selected by census sampling method. Data were gathered using particular questionnaires of musculoskeletal disorders (Nordic) and quality of life (SF-36). Collected data were analyzed by analysis of variance (ANOVA), t-test and Pearson's correlation using SPSS software (version 18).

Results: The results showed that low back disorder with prevalence of 60.9% was the most prevalent disorder among nurses. All aspects of quality of life, except for social functioning, were significantly correlated with WMSDs (P<0.05). In addition, there was a statistically significant relationship in age, gender and education level with WMSDs as well as in gender and work with quality of life (P<0.05).

Conclusions: According to this study, the prevalence of WMSDs was relatively high in nurses. In the majority of nurses, moderate quality of life was observed. Therefore, any intervention to improve quality of life and prevent WMSDs should be focused on, to reduce the physical needs and psychological pressures.


Relationship Between Workload and Prevalence of Wrist Disorders in Assembly Line Workers of Manufacturing Industry
Zahra Ordudari, Farzane Fadaei, Ehsanolah Habibi, Akbar Hassanzadeh,
Volume 7, Issue 3 (11-2019)
Abstract

Background and Objectives: Musculoskeletal disorders cause about half of all work-related disease, and are the major cause of loss of time, increased costs, and labor injury. This study aims to evaluate the workload and its association with the prevalence of wrist disorders. It was carried out in the assembly workers of a manufacturing industry.
Methods: This cross-sectional study was conducted among 120 female workers employed. Theit mental workload, physical workload and prevalence of wrist MSDs were evaluated using the NASA-TLX, the OCRA method and the Nordic wrist and hand scan questionnaire respectively.
Results: The NASA-TLX showed that the physical demands and effort with mean scores of 78.79 and 78.37 were respectively the most important subjective mental workload (SMWL) scale. Also The results on the basis of the OCRA risk level showed that the highest right-hand risk was at risk level 3 and the highest left-hand risk was at risk level 1 .The Statistical analysis showed that OCRA risk levels and mean scale physical demands and efforts were significantly higher in those with wrist pain than those without pain (P<0.05).There was a direct correlation between the severity of the wrist pain with the OCRA risk index in both hands (P=0.001) and the total score of NASA (r=0.232, P<0.05).
Conclusion: It was revealed that mental load was high in assembly lines of the manufacturing industry and this result was also confirmed by physical evaluation. This study indicated that overall score of SMWL can affect the incidence of MSDs. That is why mental workload should be considered as a risk factor for MSDs.


Investigating the Anthropometric Fit of Scientific-Research Laboratory Technicians with Their Workstations: A Case Study in Hamedan University of Medical Sciences
Zohreh Karami, Zahra Naserzadeh, Neda Mahdavi,
Volume 10, Issue 4 (3-2023)
Abstract
Objectives: Musculoskeletal disorders (MSD) induced by work are common in laboratory jobs. One of the most important reasons for disorders is the lack of personal fit with a workstation. This study aims to evaluate the body posture of experts in scientific-research labs and explore their anthropometric fitness with workstations on the campus of Hamedan University of Medical Sciences in 2022.
Methods: To investigate the MSD prevalence associated with the work, it was used the Nordic questionnaire and, for evaluating the posture, the Novel Ergonomic Postural Assessment (NERPA) technique. Then, to check the compatibility of laboratory personnel with the workstations, some interventions were proposed to improve them.
Results: According to the findings, the highest amount of prevalence of pain over the past year was in the neck area, 68.7%, and waist area, 59.37%, respectively. To assess the body posture using the NERPA technique, the middle level of corrective actions as well as more research was required. Also, the highest score of the risk, i.e. 40.62%, was allowed to the neck. In most activities, there was not any match between the dimensions of the personal body and the workstation.
Conclusion: The results indicated that the prevalence of MSD symptoms is high among the experts in research laboratories, and the risk levels of ergonomic assessment are in the middle. It seems that the lack of anthropometric matches with the workstation generally has led to adverse work posture and thus, the prevalence of MSD disorders. So, providing anthropometric matches between people who work in research laboratories and their workstations is essential to reducing these disorders.

Investigation of Posture Assessment Methods in Dentists and Dental Students: A Systematic Review
Seyeydeh Hasti Sadati, Mehdi Asghari, Maedeh Moradi Farahani,
Volume 12, Issue 1 (4-2024)
Abstract
Objectives: Awkward posture is a primary cause of musculoskeletal disorders (MSDs) in the dental profession due to the nature of dental activities. This study aimed to examine both observational and device-assisted posture assessment methods used to study dental professionals as well as the reported prevalence of MSDs among them.
Methods: A search was conducted in Scopus, PubMed, and Google Scholar databases for studies performed from 2000 to 2021 using specified keywords. In total, 31 out of the 541 articles found in the initial search were finally included in this study after the exclusion of ineligible articles, duplicates, conference presentations, systematic reviews, and letters to the editor.
Results: Based on the findings, the neck (58%), back and waist (54.9%), and shoulder and hand (29%) areas had the highest reported pain and disorder. Several posture evaluation methods, namely Rapid Upper Limb Assessment (19.4%), Rapid Entire Body Assessment  (19.4%), Electromyography (EMG, 13.8%), and Quick Exposure Check (QEC, 8.3%), were the most frequently used methods among all 17 methods employed in the studies.
Conclusion: Among the observational methods, the QEC method was the most practical one as it considered the experiences of dentists and various dimensions of dental tasks. Moreover, the EMG method was the most suitable device-assisted method for the assessment of posture in dentists. The use of questionnaires in conjunction with evaluation methods appears to enhance the understanding and effectiveness of posture assessment.
