“…One of the ergonomist's main goals is to improve musculoskeletal health in the workplace [3]. Intervening programs, standards, and several instructions have been inducted to reduce the occurrence rate of these disorders among the working society.…”

“…Analyzing the levels of the prevention of the factors leading to these disorders can be the basis of programming and ergonomic interventions in the workplace [1,4]. Although many factors, such as biomechanical dangers, genetic factors, morphological defects, and psychosocial disease lead to work-related problems, it is only possible to control the biomechanical and psychosocial factors [3].…”

“…Body position in the workplace can lead to work-related MSDs. According to studies, to determine the intensity of physical activity, it is necessary to consider body position, the range of motion, force applied, the number of the repetitions of the activity, and the duration of work [3]. Among these, the work motions and positions are important factors that must be included in the professional health analysis.…”

“…Among these, the work motions and positions are important factors that must be included in the professional health analysis. Studies show that people's position during work is directly tied to their MSDs [3,5]. Improper, asymmetric, repeated, and continuous working positions pose excessive pressure on the body structure, eventually, this force exceeds the maximum body stress and leads to injuries [3].…”

Therefore, it can be a good base for decision-making about workplace changes and ergonomic interferences to analyze and determine the danger of bad body position during work and its effect on MSDs [6].…”

Background and Objectives: This study aimed to determine the prevalence rate of musculoskeletal disorders and evaluate the body position in routine tasks among orthotists and prosthetists. Methods: Forty orthotists and prosthetists were included. The scores of the Nordic Musculoskeletal Questionnaire and the Rapid Entire Body Assessment were used to determine the prevalence rate of musculoskeletal disorders and analyze the work position of orthotists and prosthetists, respectively. An examiner evaluated 10 working postures that were dominantly used every day, in each orthotist and prosthetist. Results: Among the orthotists, 55.6% of men and 47% of women suffered from pain in the trunk, neck, and lower limbs. Nearly similar results were seen in the upper limbs (74.1% men and 45.5% women). Such high prevalence rates were not seen in prosthetists. The analysis of the Rapid Entire Body Assessment scores based on the working task and gender of the orthotist and prosthetist showed that more than 60% of the workers achieved a score of 4 to 7 approximately in half of the tasks. It shows the medium risk of musculoskeletal disorders, thus, corrective action is necessary. Conclusion: Based on the findings, musculoskeletal disorders are highly prevalent among orthotists and prosthetists, especially in the orthotist workers. To reduce these disorders, it is recommended to add ergonomic topics and training courses for working with devices to increase the knowledge of specialists and apply and select practical tools based on the principles of ergonomics.

BACKGROUND: Traffic enforcers are vulnerable to work accidents, injuries, and illnesses because they are commonly exposed to ergonomic risk factors while performing their tasks. OBJECTIVE: The purpose of this study is to determine the effects of environmental risk factors and postural risk factor to the prevalence of musculoskeletal disorders (MSDs) among traffic enforcers in Manila City, Philippines using binary logistic regression analysis. METHODS: A total of 120 participants were included in the study. The Nordic Musculoskeletal Questionnaire (NMQ) and Rapid Entire Body Assessment (REBA) were utilized. In addition, several devices such as a noise dosimeter, digital air thermometer, and IAQ sensors were also utilized to measure the environmental exposure of enforcers during their work shift. RESULTS: The prevalence of MSDs among traffic enforcers was high, with 71% of the respondents reporting symptoms of MSDs in more than one part of the body for the past 7 days. The body part that has highest prevalence was upper back, followed by lower back, and legs/ankles. Logistic regression analysis revealed that awkward work posture (OR = 4.61, 95% CI = 2.17, 9.83), noise exposure (OR = 1.42, 95% CI = 1.11, 1.82), heat exposure (OR = 0.53, 95% CI = 0.85, 1.05), and pollution exposure (OR = 0.94, 95% CI = 0.85, 1.05) were significant contributors for the prevalence of MSDs among traffic enforcers in Manila City. CONCLUSION: The prevalence of MSDs among traffic enforcers is caused by their work posture and exposure to psychosocial factors such as noise, heat, and poor air quality. Thus, to minimize the risk of MSDs, it is suggested to provide administrative controls, such as job rotation or shifting, and introduce frequent rest breaks. It is also recommended to provide enforcers with appropriate personal protective equipment, such as cooling vests, noise-canceling earplugs and N95 facemasks. This would help in uplifting musculoskeletal health for traffic enforcers and other workers in a similar field.
