BACKGROUND Certified Hand Therapy is a subset of occupational/physical therapy that is relatively unknown to the common individual. Certified Hand Therapists (CHTs) help those with upper extremity injuries, whether it be those with workplace injuries, those who suffered a traumatic injury or those recovering from major surgery to reach the point where they are able to be independent and back to doing daily life activities. OBJECTIVE This study aimed to discern the roles that Certified Hand Therapists have in rehabilitating individuals with upper extremity injuries, to assess their participation in work-related injury prevention, to examine with whom CHTs interact with during the rehabilitation process, and to gain insight into how the relationships between CHTs and occupational safety professionals can be improved. METHODS Structured interviews were conducted with eight occupational therapists who are Certified Hand Therapists or are in the process of being certified. Interviews were recorded, transcribed and analyzed to determine themes relative to the study objectives. RESULTS Content analyses determined trends in job roles, interactions with occupational safety professionals, the importance of patient education in prevention and rehabilitation and barriers to effective treatment of work-related injuries. CONCLUSION CHTs shared similar thoughts regarding their profession. CHTs revealed common themes in the eight interviews conducted. Specifically, many CHTs believe education is a vital part of the profession in terms of improving the profession and in the rehabilitation process. In addition, patient compliance and the current workers' compensation system were seen as challenges when rehabilitating patients.

BACKGROUND Errors can have dangerous consequences, resulting in a preventive strategy in most company-based technical vocational education and training (TVET). On the contrary, errors provide a useful opportunity for learning due to mismatches of mental models and reality and especially to improve occupational safety and health (OSH). OBJECTIVE This article presents a didactic concept for developing a learning system based on learning from errors. Learners shall directly experience the consequences of erroneous actions through presenting error consequences in augmented reality to avoid negative, dangerous, or cost-intensive outcomes. METHODS Empirical data prove errors to be particularly effective in TVET. A formal description of a work system is systematically adopted to outline a connection between work, errors concerning OSH, and a didactic concept. A proof-of-concept systematically performs a use case for the developed learning system. It supports critical reflections from a technical, safety, and didactical perspective, naming implications and limitations. RESULTS By learning from errors, a work-based didactic concept supports OSH competencies relying on a learning system. The latter integrates digital twins of the work system to simulate and visualise dangerous error consequences for identified erroneous actions in a technical proof-of-concept. Results demonstrate the ability to detect action errors in work processes and simulations of error consequences in augmented reality. CONCLUSION The technical learning system for OSH education extends existing learning approaches by showcasing virtual consequences. However, capabilities are limited regarding prepared learning scenarios with predefined critical errors. Future studies should assess learning effectiveness in an industrial scenario and investigate its usability.

BACKGROUND The Bioservo Ironhand ® is a commercially available active hand exoskeleton for reducing grip-induced stress. OBJECTIVES The study aimed at quantifying the effect of the Ironhand ® exoskeleton on the myoelectric muscle activity of forearm flexor and extensor muscles in three relevant assembly grip tasks: 2-Finger-grip (2Finger), 5-Finger-grip (5Finger) and Full grip (FullGrip). METHODS Twenty-two subjects were tested in three different exoskeleton conditions for each grip task (overall 3×3×10 = 90 repetitions in randomized order): Exoskeleton off (Off), Exoskeleton on, "locking tendency" 0% (On_LT0), and Exoskeleton on, "locking tendency" 85% (On_LT85). Muscle activity was measured at 25% of the participant's maximum grip force using two EMG sensors at the M. flexor digitorum superficialis (M.FDS) and one at the M. extensor digitorum (M.ED). RESULTS The effect of the Ironhand ® exoskeleton varied depending on the grip task and the participant's sex. A statistically significant reduction in muscle activity of the M.FDS was found only for male subjects in the FullGrip condition. No reduction of muscular activity in the M.FDS was found for the other grip tasks (2Finger, 5Finger). For the females in the 2Finger condition, mean muscle activity of M.FDS even increased significantly in On_LT0 compared to Off. Besides differences between grip tasks and sex, the current study revealed substantial individual differences. CONCLUSIONS In addition to testing for statistical significance, a detailed exploratory analysis of exoskeleton effects at subject level should be performed to evaluate these from a safety and regulatory perspective.

BACKGROUND The likelihood of infection with SARS-COV-2 (COVID-19) in the dental office is considered high. OBJECTIVES Assessing the impact of the COVID-19 on dental practices and anxiety levels in risk group Brazilian dentists. METHODS A cross-sectional study was performed using an online questionnaire. The data obtained were analyzed using the IBM SPSS 25.0 software (Pearson's Chi-square association test, multivariate logistic regression, and Poisson multiple regression), with subsequent calculation of the odds ratio at a 95% confidence interval, with a significance level of 5%. RESULTS Responses of 578 dentists distributed in all regions of Brazil were collected. Most of the dentists were female, with an average age of 35. Of the participants, 23.4% were part of the increased risk group for COVID-19. The professionals who belonged to the increased risk group had a greater chance of not feeling prepared to perform consultations (OR = 1.67) and were not performing any procedures during the pandemic (OR = 2.03). Belonging to the increased risk group did not influence anxiety levels among the dentists. The factors associated with increased anxiety were being female, being younger, working in the southeastern region of the country, being afraid of contracting COVID-19 while working, and being concerned for one's professional future. CONCLUSIONS The pandemic has had a negative impact on the professional practice of individuals at risk, but the level of anxiety was like professionals who were not part of the increased risk group for COVID-19.

BACKGROUND Nursing is associated with many stressful situations that can lead to fatigue, reduced efficiency, and physical and mental illness. Safety climate is one of the most important indicators of safety management performance assessment that assesses employees' attitudes towards safety issues. OBJECTIVE The purpose of this study was to investigate the relationship between safety climate and occupational fatigue in nurses. METHOD This descriptive-analytical study was performed on nurses working in hospitals affiliated to Zabol University of Medical Sciences in 2019. 143 nurses were selected by the proportional sampling method and entered the study. Demographic questionnaires, Occupational Fatigue Inventory (SOFI), and Nurses' Safety Assessment Questionnaire were used for data collection. Statistical tests, including Independent T-Test, ANOVA, Mann-Whitney U, Kruskal-Wallis, and multivariate analysis of variance (MANOVA) were used to analyze the results using SPSS software version 21, and the multivariate structural equation was used for modeling. RESULTS The mean scores of safety climate and occupational fatigue were 67.15±12.73 and 85.09±41.49, respectively. Job and demographic variables except for the second job (P-value = 0.065) had a significant effect on the variables of safety climate and occupational fatigue. There were also higher scores for occupational fatigue and all of its subscales in the group of women compared to the group of men. CONCLUSION The results showed that occupational and demographic variables have significant effects on safety climate and occupational fatigue. There was a significant relationship between demographic variables of age, work experience, and education level with safety climate. There was also a significant relationship between education level, job satisfaction, satisfaction with colleagues and work experience with occupational fatigue. Therefore, paying attention to fatigue and safety climate of nurses in workplaces is recommended.

BACKGROUND Anthropometric data should be considered for each major population age category, specifically because of the dimension changes occurring during ageing. In elderly subjects, the physical activities and their capabilities become limited. Therefore anthropometric reference data for equipment and system designs is necessary. OBJECTIVES The aim of the study was to collect data for the body dimensions of an elderly Iranian population and evaluate the related gender and age correlations. METHODS Nineteen body dimensions were manually measured on a sample size of 317 subjects (167 male and 150 female) from four provinces of Iran. A pilot preliminary test for assessing test-retest reliability on ten body dimensions using the Intraclass Correlation Coefficient (ICC2 :1) was performed. Descriptive statistics were reported based on gender and independent samples t-tests to compare the anthropometric dimensions of both genders and age. RESULTS Results indicated higher dimensions in males, except for hip-breadth (p = 0.87). In all subjects, increasing age corresponded with: decreased standing shoulder height, eye height, and elbow height; and with sitting height and sitting knee height; while hip-breadth increased. Reliability was acceptable (ICC2.1 >0.88). In the elderly, as with adult subjects, there are significant gender differences in body dimensions, and this should be considered in equipment and system designs. Furthermore, this study demonstrated both genders differences and the consequences of aging. CONCLUSIONS From this pilot data, product designers can consider the anthropometric characteristics for elderly Iranian subjects for equipment and system designs.
