Abstract: BACKGROUND: The high spread rate of coronaviruses, specifically severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has raised concerns about the spread of the disease in crowded occupational environments. The risk of occupational exposure to coronavirus depends on the type of industry and the nature of work. Currently, most countries are working for reactivating their economies and need to improve working conditions for a safe situation during the COVID-19 pandemic. OBJECTIVE: The present work aimed to investigate the current engineering and administrative control measures, which are necessary to protect workers against COVID-19 in workplaces. METHODS: The current …strategies, including engineering control, administrative control, personal protective equipment, and their efficiencies, were reviewed and discussed. RESULTS: Reviewing the literature indicated that a collection of control approaches should be implemented for an effective control of the virus. Control measures could be selected based on the risk of exposure to COVID-19. The results also revealed that relying solely on a specific control measure could not effectively control the outbreak. CONCLUSION: In conclusion, employers and health professionals must continually monitor international and local guidelines to identify changes in recommendations to make their workplaces safer. Establishment of an expert team in any workplace for the implementation of more effective control measures is warranted, as well. Show more

Abstract: BACKGROUND: The World Health Organization (WHO) has declared novel coronavirus (COVID-19) infection a global pandemic due to the fast transmission of this disease worldwide. To prevent and slow the transmission of this contagious illness, the public health officials of many affected countries scrambled to introduce measures aimed at controlling its spread. As a result, unprecedented interventions/measures, including strict contact tracing, quarantine of entire towns/cities, closing of borders and travel restrictions, have been implemented by most of the affected countries including the Kingdom of Saudi Arabia. OBJECTIVES: The aim of this paper is to share health care professionals’ perspectives …who are experiencing COVID19 firsthand in a foreign land. In addition, the role of the Saudi governance to combat the current situation is also discussed. DISCUSSION: Personal and previous experiences as related to Middle East respiratory syndrome coronavirus (MERS-CoV) by the authors has been compared to the current situation and how it affected our thoughts and management. A review of the evidence-based literature was conducted to investigate the demographics of the region; and to understand the awareness of the various tools that are available and how they were utilized in the present situation of pandemic. CONCLUSIONS: Saudi Arabia has been challenged during the pandemic as are other countries. Show more

Abstract: BACKGROUND: As the pandemic process, COVID-19 has a serious occupational safety risk for healthcare professionals. Therefore, determining their health and safety perceptions and attitudes in the pandemic process is very important. This study aims to determine which is more effective in work accident prevention behavior: safety awareness and competencies of healthcare professionals or perception of fatalism. METHOD: For this purpose, a questionnaire was applied to 326 healthcare professionals. The questionnaire consists of four parts: (1) demographic information of the employees, (2) scale of preventing occupational accidents, (3) fatalism perception scale in occupational health and safety, and (4) security …awareness and competency scale. Descriptive statistical methods, multiple regression and correlation analysis were used in the analysis of the data. RESULTS: It was determined that the participants’ safety awareness and competencies were at the high level and their fatalism perceptions were at the low level. The average of the responses given by the participants to the scale of preventing work accidents was above the middle level. According to the study, the safety awareness and competencies of health workers were found to be about three times more effective on the behavior of preventing work accidents than the perception of fatalism. CONCLUSION: In conclusion, it is important to recommend managers to take the step to increase the safety awareness and competencies of those working in their institutions. Show more

Abstract: BACKGROUND: The aim of this study was to evaluate the self-perceived competency (FSPC) of medical faculty in E-Teaching and support received during the COVID-19 pandemic. METHODS: An online well-structured and validated faculty self-perceived competency questionnaire was used to collect responses from medical faculty. The questionnaire consisted of four purposely build sections on competence in student engagement, instructional strategy, technical communication and time management. The responses were recorded using a Likert ordinal scale (1–9). The Questionnaire was uploaded at www.surveys.google.com and the link was distributed through social media outlets and e-mails. Descriptive statistics and Independent paired t -test were …used for analysis and comparison of quantitative and qualitative variables. A p -value of ≤0.05 was considered statistically significant. RESULTS: A total of 738 responses were assessed. Nearly 54% (397) participants had less than 5 years of teaching experience, 24.7% (182) had 6–10 years and 11.7% (86) had 11–15 years teaching expertise. 75.6% (558) respondents have delivered online lectures during the pandemic. Asynchronous methods were used by 61% (450) and synchronous by 39% (288) of participants. Moreover, 22.4% (165) participants revealed that their online lectures were evaluated by a structured feedback from experts, while 38.3% participants chose that their lectures were not evaluated. A significant difference (p  < 0.01) was found between FSPC scores and online teaching evaluation by experts. The mean score of FSPC scale was 5.62±1.15. The mean score for student’s engagement, instructional strategies, technical communication and time management were of 5.18±1.60, 5.67±1.61, 5.49±1.71 and 6.12±1.67 respectively. CONCLUSIONS: Medical faculty members were found somewhat competent in E-teaching for student engagement, instructional strategy, technical communication and time management skills. Faculty receiving feedback was more competent in comparison to peers teaching without feedback. Show more

Abstract: BACKGROUND: The public health strategies for prevention of SARS-CoV-2 infection have included closing the national borders and cancelling international flights, which has severely affected free crew changes. This caused prolonged stay on board or at home for seafarers, who should be recognized as ‘key’ workers regarding their essential role in maintaining the flow of vital goods. OBJECTIVE: Using a general inductive approach, this qualitative study aims to describe how the COVID-19 pandemic reflects on seafarers’ well-being. The study focused on obtaining personal experiences from seafarers on board, and seafarers at home, relating to the current world pandemic. …METHODS: A convenience sample consisting of 752 seafarers from the international seafarers’ population participated in an online study in spring 2020. The questionnaire used included questions relating to basic sociodemographic and work characteristics, and one open question which addressed seafarers’ personal experiences. The data obtained was analysed by thematic analysis. RESULTS: The emerged themes included mental , physical , social and economic well-being . Most of the answers of seafarers located on board related to threatened mental, physical and social well-being, while seafarers at home reported mostly on threats to their economic well-being. CONCLUSION: Seafarers’ well-being is seriously threatened by preventive measures relating to the COVID-19 pandemic. Results are discussed in relation to earlier findings in the area of occupational stress in seafaring. Overall, the data obtained portrays existing underlying occupational structures in the seafaring sector, which are rendered more visible due to the COVID-19 pandemic. In short, seafarers describe their reality as far away from the concept of ‘key’ or ‘essential’ workers. Show more

Abstract: BACKGROUND: In recent years, the elderly population has increasingly worked in various workplaces. Hence, measurements to assess the work attention of the elderly has become an important need. OBJECTIVES: The aims of this research project are to develop an iPad-based attention assessment tool, “Shih-Hsu Test of Attention” (SHTA) for work attention, that adopts touchscreen as the medium interface, and to explore criterion-related validity and test-retest reliability of this new attention assessment tool for elders. METHODS: Thirty-one participants aged between 65–85 years were recruited in this study on a voluntary basis. Each participant was assessed two times. …The participants completed both the SHTA and Chu’s Attention Test (CAT), and the SHTA was used to test participants after three weeks. RESULTS: The analytical results demonstrate that the SHTA has acceptable criterion-related validity (γ= 0.400, p  < 0.05* ) and test-retest reliability (ICC = 0.920, p  < 0.01** ). CONCLUSIONS: Our preliminary findings show that the iPad-based auditory attention assessment tool, SHTA, has satisfactory criterion-related validity and test-retest reliability, which supports the use of SHTA as an attention assessment tool for older employees.

Abstract: BACKGROUND: Returning to work (RTW) is an essential goal for many stroke survivors. Currently, the prevalence of RTW post stroke in developing countries such as Jordan is unknown. Additionally, more research is required to identify factors that contribute to RTW post stroke. OBJECTIVES: This study aims to (1) determine the prevalence of RTW among stroke survivors in Jordan, and (2) determine the predictors of RTW from a holistic perspective using the Occupational Therapy Practice Framework (OTPF) 3rd edition. METHODS: Recruitment was carried out from different Jordanian hospitals and rehabilitation centers. A complete battery of outcome measures …was used to reflect OTPF domains. These included outcome measures of occupations, client factors, performance skills, and context and environment. Logistic regression was used to determine factors that predicted RTW. RESULTS: 69 participants were enrolled; 45 Males, 24 females; mean age±SD, 52.2±11.07 years. Only 29% succeeded in RTW during the first year after stroke onset. The highest percentage of RTW was among craft workers (40% ), and those who were self-employed (60% ). Of those who resumed work, 35% returned to their previous work, while 65% needed to make work modifications, or change positions or jobs. Factors that predicted higher rates of RTW were walking speed (Odds ratio (OR)=0.004, 95% confidence interval (CI)=0.00–0.55, P  < 0.02), as well as absence of environmental restrictions (OR = 21.16, 95% CI = 1.91–233.5, P  < 0.013). CONCLUSIONS: The alarming low prevalence of RTW among stroke survivors in Jordan emphasizes the essential need to develop vocational rehabilitation programs. Clinicians should pay attention to enhancing walking abilities and reducing environmental restrictions post stroke, in order to improve the occurrence of RTW. Show more

Abstract: BACKGROUND: Metabolic syndrome is an increasing disorder, especially in night workers. Drivers are considered to work during 24 hours a day. Because of job characteristics such as stress, low mobility and long working hours, they are at risk of a metabolic syndrome disorder. OBJECTIVES: The purpose of this study is a meta-analysis and systematic review of the prevalence of metabolic syndrome in drivers. METHODS: In this systematic review, articles were extracted from national and international databases: Scientific Information Database (SID), Iran Medex, Mag Iran, Google Scholar, Science Direct, PubMed, ProQuest, and Scopus. Data analysis was performed …using meta-analysis and systematic review (random effect model). The calculation of heterogeneity was carried out using the I2 index and Cochran’s Q test. All statistical analyses were performed using STATA software version 11. RESULTS: A total of nine articles related to the prevalence of metabolic syndrome in drivers in different regions of the world from 2008 to 2016 were obtained. The total sample size studied was 26156 with an average of 2906 samples per study. The prevalence of metabolic syndrome in drivers was 34% (95% CI: 30–37) CONCLUSIONS: According to the results of this study, the prevalence of metabolic syndrome in drivers is high. Occupational stress, unhealthy diet and physical inactivity cannot be cited as causes of metabolic syndrome prevalence in drivers. Therefore, to maintain and to improve the health of this group, the implementation of preventive, therapeutic and rehabilitation measures for these people as well as training should be considered.

Abstract: BACKGROUND: Smartphones (SPs) are widely used by people of all age groups and genders. Users spend many hours per day on the SPs for different purposes, which imposes significant stress on their musculoskeletal system. OBJECTIVES: This study explored head forward flexion, lateral bending angle, and viewing distance while working with a SP in sitting/standing postures and one-handed/two-handed grips. The users’ performance as well as pain development were also investigated. METHODS: Participants answered a questionnaire on pain experience before and after SP usage. Neck kinematics of 20 SP users were monitored by a motion analysis system while …doing three tasks (typing, video watching, and reading) in sitting and standing postures. Performance was evaluated by number of typed words, amount of errors in typing, and total read words. RESULTS: The results indicated a significant increase in pain complaints in neck and upper limbs after test completion. Working with SPs in sitting and standing postures were, respectively, associated with greater head forward flexion for watching and viewing distance for two-handed typing tasks. Higher left lateral bending values were measured for one-handed watching and reading tasks in standing posture. The performance measures were superior for two-handed grips in all conditions. CONCLUSIONS: Overall, using SPs in sitting posture creates greater head forward flexion and lower lateral bending angles in all tasks and grip types. The findings of this study can be used to provide recommendations for SP users. Show more

Abstract: BACKGROUND: While kinesio taping (KT) is used in several clinical settings to correct posture and reduce pain, KT effects during smartphone texting are unknown. OBJECTIVE: To investigate the effects among healthy young adults of KT on neck-shoulder discomfort and electromyographic (EMG) responses of neck and upper trunk muscles during smartphone texting. METHODS: Twenty-four participants performed a 30-minute texting task on a smartphone using both hands at two separate times under one of two conditions: KT on the right shoulder and no taping. Neck-shoulder discomfort was assessed, along with the normalized root mean square (NRMS) and normalized …median frequency (NMF) of the right cervical erector spinae (CES), lower trapezius (LT), and serratus anterior (SA). RESULTS: Compared to baseline, both groups had significantly greater neck-shoulder discomfort, and NRMS and NMF of all muscles (p  < 0.001) after performing a 30-minute texting task. Comparing between groups, the KT group experienced significantly less neck-shoulder discomfort, and demonstrated delayed deterioration of NRMS and NMF of right CES and LT muscles (p  < 0.05). CONCLUSIONS: During smartphone texting, KT on the shoulder decreased neck-shoulder discomfort and delayed reduction of activation and fatigue of neck and upper trunk muscles among healthy young adults.

Abstract: BACKGROUND: Order picking activities are the most labor-intensive processes in retail warehouses. Although various automated order picking technologies have been developed recently, human intervention continues to be required. Most advanced order picking systems can be classified into automated storage and retrieval system (AS/RS) and moving robot types. Both types of goods-to-picker systems aim to reduce the picker’s travel time required to determine product locations and to move these products to meet customer requests. OBJECTIVE: Many studies on the efficiency and effectiveness of automated order picking systems have focused solely on system performance. Since human operators play an essential …part in order picking systems from both the effectiveness and efficiency point of view, the work-related risk factors for the workers interacting with these systems should also be evaluated. In this paper, we assess the ergonomic design features of two system types, a moving robot (MR) and automated storage and retrieval system (AS/RS), focusing on the assessment of the risk factors for work-related postural stresses. METHODS: We compare the performance factors of two order picking systems, i.e. MR and AS/RS, by applying a digital human modeling and simulation, and assessing the total average physical activity exhibited by human operators on a given order picking task. RESULTS: The AS/RS type order picking system exhibited a lower risk for task-related postural stresses for warehouse workers. CONCLUSIONS: The picking station for moving robot (MR) order picking system requires design changes in order to reduce postural stresses during human operator’s interaction with such a system.

Abstract: BACKGROUND: The practice of occupational therapy in parasports aims to improve participation in sports as an occupation, reducing barriers stemming from the environmental factors. OBJECTIVE: To analyze the process of choice, prescription and follow-up of assistive technology (AT) in competitive adolescent parasports using the theoretical model Matching Person and Technology. METHODS: Case study with 3 adolescents from 12 to 18 years old in Bocce and Para-badminton modalities was performed. Characterization Questionnaire; Quebec User Evaluation of Satisfaction with assistive Technology (B-Quest); Assistive Technology Device - Predisposition Assessment (ATD PA-Br); Brazil Criteria and Intervention Report were used. …RESULTS: Level of income was intermediate and low. The AT used were handcrafted by family and coaches. The Psychosocial factors detected were low privacy, autonomy, discomfort and device appearance. Pre-intervention there was dissatisfaction with AT related to the device and the context. Post-intervention, satisfaction scores increased. CONCLUSIONS: The model was a positive guide regarding the intervention of technology in the parasport, directing the participation of the specialist with the parathletes, their family and coaches, in the continuous monitoring of its use. This was key for the satisfaction in using the AT in sports, besides contributing to their occupational performance and maintaining people with disability in parasports, increasing the possibility of adolescents becoming professional para-athletes. Further studies in this area are suggested. Show more

Abstract: BACKGROUND: Marching band activities consist of both physically and cognitively demanding tasks. The demands that this activity has on players has largely been unstudied. OBJECTIVE: The goal of this study was to investigate the effects of players’ experience level, role, and gender on the workload of marching band players via a field study. METHODS: Surveys were issued during one game day to the Oregon State University Marching Band (OSUMB) in the fall of 2017. Increments of discomfort ratings and workload ratings were gathered. The three independent variables were experience level (novice or experienced), role (leader …or non-leader), and gender. RESULTS: Novice players had a higher discomfort for their left hand and a higher level of cognitive demand as opposed to experienced players. Leaders had a higher increment of discomfort in their neck and upper back, and higher workload ratings in their performance workload and overall weighted workload than the non-leaders. Gender had no effect on increment of discomfort and workload, but some trends were noted. CONCLUSIONS: This study indicates that players’ role and experience, but not gender, can influence their workloads and discomfort. Show more

Abstract: BACKGROUND: From the 1960s until the beginning of the 1990s, the construction industry in Sweden received support for health and safety issues from Bygghälsan, an Occupational Health Service (OHS) that targeted the construction industry. In the 1990s, a reorganization of the OHS changed the relations between the actors involved. OBJECTIVES: This study explores these changed relations between the construction industry and the “old” industry-specific Bygghälsan versus the relations with “new” external OHS. METHODS: Semi-structured interviews were conducted with 22 interviewees from the construction industry and individuals involved in OHS which were transcribed and analyzed. …RESULTS: The results suggest that OHS have changed towards a more general character instead of tailor-made services which has had a negative effect on the relations. Further, Bygghälsan was perceived as being a part of the construction industry while contemporary OHS providers were perceived as outsiders which further complicates building trustful relations. CONCLUSIONS: The relation between the construction industry and Bygghälsan was perceived as better compared to the relations with the new companies providing external OHS. The main barrier to building better relations is the perception that contemporary OHS do not have the same knowledge about the construction industry as Bygghälsan. Show more

Abstract: BACKGROUND: Breast cancer treatments lead to several comorbidities in the upper limbs, such as pain and stiffness, hindering physical functions and the return to work. OBJECTIVE: To explore the functionality and factors associated with work behaviour among manual and non-manual Brazilian workers who have recovered from breast cancer. METHODS: This is an observational cross-sectional study involving Brazilian breast cancer survivors. The sociodemographic, work, and clinical aspects were assessed through clinical records, upper limb disability, and human functionality obtained from 62 women. Multiple and univariate logistic regressions were used to identify the association of variables on return …to work, p  < 0.05. RESULTS: 56.5% of women did not return to work, the mean time for returning to work was 16 months (±15.21), absenteeism from work lasted 41 months (±34.58). Modified radical mastectomy (OR = 5.13, 95% CI = 1.35 to 18.66) and moderate-to-severe disability levels in the upper limbs (OR = 6.77, 95% CI = 1.86 to 24.92) were associated with not returning to work. The loss of productivity was higher among non-manual workers (21.5%) (p  = 0.040). CONCLUSIONS: The rates of not returning to work after breast cancer treatment are high. Women who did not return to work presented higher levels of disability. Show more

Abstract: BACKGROUND: Recent studies have started disentangling components of disturbed sleep as part of the post-concussive syndrome, but little is known about the workers with an injury’ perspectives on post-injury sleep changes or what causes these changes. OBJECTIVES: To determine the effects of work-related concussion/mild traumatic brain injury (wr-mTBI) on perceptions of refreshing sleep in workers with an injury and to identify the relevant factors responsible for sleep changes. METHODS: We studied post-concussive changes in sleep in 66 adults (50% male workers, 42% aged 30–50 years, median post-injury days: 155) who had sustained wr-mTBI and experienced functional …limitations long after the injury. We collected sociodemographic, occupational and health status data and identified variables related to post-concussive changes in refreshing sleep. RESULTS: Forty-seven workers with wr-mTBI (79% of male workers, 64% of female workers) perceived their sleep as being refreshing before injury and unrefreshing afterwards (χ2 = 67.70 for change, χ2 = 27.6 for female and χ2 = 41.1 for male workers, p  < 0.0001). Post-concussive losses in refreshing sleep were associated with socio demographic, occupational, and health status data variables. Sex stratification revealed differences between male and female workers. CONCLUSIONS: Workers with wr-mTBI experience clinically meaningful changes in refreshing sleep that are associated with modifiable variables. The observed differences in functional outcomes between male and female workers warrant further study. Show more

The Beck Depression Inventory (BDI), the Sense of Coherence Questionnaire (SOC-29) and the Perceived Stress Questionnaire (PSQ) were used. RESULTS: The examined group had an average level of sense of coherence and a low level of …stress. One out of four students exhibited mood disorders. The factors associated with the prevalence of mood disorders among studied students were as follows: female (gender), lack of regular physical activity, poor financial situation, lack of friend to talk to in case of problems, dissatisfaction with the chosen field of study, and being inadequately prepared to work as a physiotherapist. CONCLUSIONS: The results of the study indicate an increased prevalence of mood disorders among students of physiotherapy. It is suggested that this situation may require the implementation of effective psychoprophylactic activities during the course of studies and broadly understood education about the psychophysical wellbeing of students, especially as they will work in an environment that requires high resistance to stress and support for other people in a crisis situation.

Abstract: BACKGROUND: Despite mechanization development, leafy vegetable cultivation (LVC), as a labor-intensive activity in both developed and developing countries, still suffers from heavy physical activities. OBJECTIVE: The present study evaluated the human physiological strains of LVC’s workers to identify relationships among contributing factors affecting human physiological strains. METHODS: Thirty male workers were included in this study. Working heart rate (HR) was measured using a heart rate sensor during various operations. The time taken to treat a known area was measured using a stopwatch to calculate work speed (or field capacity (FC)) for each operation. Pearson correlation coefficient …and linear regression were used to investigate the relationships among HR, heart rate ratio, FC and mechanization status (MS), and human energy expenditure rate and total energy expenditure per unit area. RESULTS: The highest HR was at seedbed preparing (120.1 beats/min) and lowest at manual harvesting (87.8 beats/min). Manual hoe-used operations (seedbed preparing, manure application and irrigating) were demonstrated as the critical operations concerning physiological strains. The operations performed by machine power corresponded to a high FC. CONCLUSIONS: Variables influencing the area treating speed (i.e. MS and FC) are negatively linked to the human energy consumed per unit area and variable changed in time unit (i.e. HR) was positively linked to the human energy expenditure speed.

Abstract: BACKGROUND: Health and safety performance measurements aimed to provide information on the progress and current situation of organizational strategies and activities. OBJECTIVES: We developed a model to determine and select safety key performance indicators in order to assess safety management systems. METHODS: This study has been designed in six steps aiming at defining a model of leading performance indicators (LPIs) and selecting key performance indicators (KPIs) using the AHP method. RESULTS: According to the results analysis, 116 structural and operational indicators were defined based on the components of the OHSAS 18001 management system. For …this purpose, 19 structural, 27 operational and 33 active KPIs were selected by AHP and BN techniques. CONCLUSION: Development of LPIs is influenced by various organizational, managerial, and operational factors. LPIs extracted from the components of the OHS-MS deployed in an organization are often passive and cannot show the changes in the safety status of a workplace in a short period. The model presented in this study was designed with an emphasis on extraction of active and operational indicators, as they were capable of detecting performance changes in construction industries.

Abstract: BACKGROUND: Guidelines recommend early referral for exercise for hip pain. It is unclear if this occurs in the Australian workers’ compensation environment. OBJECTIVE: To investigate referral for exercise in workers with a compensable hip claim. METHODS: Retrospective audit of closed compensation files for workers with hip pain was performed. Exercise commencement was indicated by billing codes for physiotherapy or exercise specific consultations. Time to exercise commencement was calculated. Associations were analysed between time to exercise commencement with claim duration and diagnostic category. RESULTS: Exercise management occurred for 33/44 cases. Median time to commence exercise …for those cases that had exercise was 14 days post-injury, with 33% commencing beyond 4 weeks. Longer time to commence exercise was associated with a longer claim duration (Spearman’s rho = 0.70). Workers with a diagnosis of hip joint pain had a longer time to exercise commencement (median 49.5 days) compared to those with a diagnosis of lateral hip pain (median 14 days) or non-specific hip pain (median 4.5 days). CONCLUSION: Findings indicate practice behaviours in the workers’ compensation environment for the management of hip pain with exercise. Further investigation is warranted to see if improved adherence to guideline recommendations improves outcomes for people with compensable hip pain. Show more

Abstract: BACKGROUND: Extremity strength testing is used to determine the ability of industrial employees to perform a physically demanding occupation safely, evaluate post-injury impairment, and monitor return to function after injury. There is an unmet clinical need for a robust and granular source of normative reference values to serve as a resource for baseline data on upper extremity isometric strength. OBJECTIVE: Develop normative reference data for upper extremity strength among industrial employees and investigate associations between strength and physical job demands. METHODS: Upper extremity strength data from 107,102 industrial employees were collected post-hire. In this study, isometric …tests for pinch; hand grip; wrist pronation and supination; and flexion of the wrist, elbow, and shoulder strength were retrospectively analyzed in relationship to sex, age, and job level. Associations between strength scores and five levels of work, defined the United States Department of Labor’s Dictionary of Occupational Titles by level of physical difficulty (1–5 ), were determined. RESULTS: Higher strength scores were positively associated with more physically demanding job levels (P  < 0.001), and there was a progressive increase in strength scores with increased physical job demands for both sexes (P  = 0.0002). All strength scores differed significantly by decade of age (P  < 0.001). All scores except for pinch strength demonstrated a moderate or high positive correlation with job level (r ≥0.50). CONCLUSIONS: The normative reference upper extremity strength data collected in this study for industrial employees may be useful for evaluating rehabilitation and recovery following injury or illness. In order to utilize normalized strength data as a post-injury reference, it is important to consider job level in addition to age and sex, as these variables are highly correlated with baseline upper extremity strength.

Abstract: BACKGROUND: In developing countries, the recent increase in computer-related work has considerably increased the occupational complaint of pain. OBJECTIVE: To examine the effects of workstation design, posture and ergonomic awareness on the prevalence of pain for a year in the upper part of the body (eyes, hands, arms, shoulders, lower back, and upper back) among IT professionals in India. METHOD: To investigate the association of risk factors with the prevalence of pain in different body parts, a newly designed online questionnaire titled “A Questionnaire based on ergonomics for IT Professionals” was developed. The psychometric properties of …this questionnaire were tested. 110 computer office workers were recruited from IT companies from major cities in India. RESULTS: The confirmation of reliability and lack of redundancy of items was provided by the calculation of internal consistency (Cronbach’s alpha 0.804) and cross-validation. 60% of participants was male. Mean age was 29.73±6.09 years. The prevalence of pain for a year in the upper part of the body was 38.2%. The frequently reported pains were in the neck (22.7%), lower back area (22.7%), and eye strain (21.8%). CONCLUSION: It was identified that long working hours, excessive usage of smartphones, lack of exercise, incorrect workstation adjustments, and incorrect posture were the risk factors for the prevalence of pain.

Abstract: BACKGROUND: In developing countries, construction is a largely manual job that imposes awkward postures on workers, thus facilitating a variety of musculoskeletal disorders. Ergonomic training is known as an effective way to reduce these disorders. OBJECTIVE: This study aimed to evaluate the effectiveness of ergonomic training intervention in reducing the ergonomic risk of concrete form workers. METHODS: This quasi-experimental study was carried out on 144 concrete form workers employed in the construction projects of Gonbad-e Kāvus, Iran, Iran. Data was collected using the Nordic Musculoskeletal Questionnaire (at the pre-intervention stage) and the Rapid Entire Body Assessment …(REBA) worksheet (at the pre- and post-intervention stages). Ergonomic training was provided via face-to-face educational meetings along with presenting informative pamphlets, which took place over 45 days duration of time. Data were analyzed by the use of SPSS software version 21, t -test and Wilcoxon test. Significant level was considered at P -value less than 0.05. RESULTS: Musculoskeletal disorders were observed in all limbs of the studied workers. The most prevalent disorders were the pain in the shoulder region of lift operators (86.1%) and the pain in the back area of mixer operators (77.8%). About 99.3% of all concrete form workers were exposed to a moderate level of ergonomic risk and needed posture correction. Pre- and post-training REBA scores showed a statistically significant difference (P  < 0.05). CONCLUSION: Although the ergonomic training did reduce the ergonomic risk of workers, because of its short duration, it failed to reduce this risk to an acceptable level. It is recommended to hold both theoretical and practical training sessions over longer periods of time. Show more

Abstract: BACKGROUND: Few studies have evaluated the causes of physical inactivity in rural teachers from South America. Determining the causes and effects of physical inactivity in rural teachers could be the base for future intervention studies aiming to improve physical activity (PA) engagement in this population. OBJECTIVES: To examine the levels of PA in rural teachers and evaluate the associations between their jobs, interest in PA, body composition and practice of PA. METHODS: Body mass index (BMI) and body fat % (BF) of rural teachers from the Valparaiso Region in Chile were measured; interviews regarding PA habits, …interests and PA practice were conducted. The relationship between BF% and interest in PA and the practice of sports was analysed stratifying by sex. RESULTS: Around 71% were overweight/obese and 80% of the teachers reported not practicing any PA. These figures are higher than the Chilean national average for adults (64.5% overweight/obese). Moreover, females presented a higher BF% than male teachers (35.98% vs. 26.44%, p  < 0.05). The main causes of not performing PA were: firstly, the lack of time (51.8%), and secondly, fatigue after work and/or finishing work late. In addition, rural teachers claim that in their free time they continue to finish tasks that they were not able to complete during their working hours. CONCLUSIONS: Rural Chilean teachers show a high prevalence of obesity and low PA levels. Moreover, rural teachers have a work overload stemming from their jobs, and this could be an important link to an overall sedentary lifestyle. Further studies should focus on the relationship between teacher obesity, physical activity, nutrition and work overload. Show more
