Abstract: BACKGROUND: Vocational rehabilitation (VR) aims to help people with disabilities to return to the labour market. Though, there is not much evidence on its effectiveness. OBJECTIVES: We explore the effect of vocational training programmes in VR and the VR status itself on employment outcomes. METHODS: Using two samples from administrative data by the German Federal Employment Agency, we applied propensity score matching. We followed rehabilitants commencing VR in 2009/2010 (N  = 7,905) for four years (comparison I) and general training participants with and without VR status completing training in 2012/2013 (N  = 21,020) for one year …(comparison II). For harmonisation purposes, we only considered individuals aged between 25 and 40 and excluded those in employment at the beginning of VR or training. RESULTS: Concerning the effect of training in VR (comparison I), we observe a lock-in effect during training (p  < 0.001) due to an involvement in VR; after training, participants are more likely to obtain unsubsidised employment (0.05, p  < 0.05) than non-participants, but there is no statistically significant income difference after four years. Regarding the effect of the VR status (comparison II), rehabilitants are more likely to take up (un-)subsidised employment (0.04, p  < 0.01; 0.02, p  < 0.001) after training, exhibit longer employment durations (19 days, p  < 0.001) and achieve higher average incomes (2,414 euro/year, p  < 0.001) compared to non-rehabilitants. CONCLUSIONS: Training participation helps to improve employment participation of rehabilitants. However, a longer observation period is recommended. Furthermore, the VR status itself leads to more sustainable and better-paid employment. This is due to more comprehensive support and longer-term subsidised employment opportunities. Show more

Abstract: BACKGROUND: Typically, bricklayers in developing countries’ contexts manually lay bricks, concrete blocks and other similar materials to construct walls and buildings which make them susceptible to work-related musculoskeletal disorders (WRMSDs). The burden of WRMSDs among this high-risk group seems has not been well documented. OBJECTIVES: This study examined the prevalence of WRMSDs among bricklayers in Nigeria. METHODS: A cross-sectional survey of 118 consenting bricklayers from a Nigerian setting was carried out. The standardized Nordic musculoskeletal disorder questionnaire and a proforma were used to profile the prevalence of WRMSDs and socio-demographic information of the respondents. Data was …analyzed using descriptive and inferential statistics. Alpha level was set at p  < 0.05. RESULTS: The 12-months and 7-days prevalence of WRMSDs were 87.3% and 67.4%. Shoulder (61.0%) and the low-back (59.3%) were the two most affected anatomical sites based on 12-month prevalence. WRMSDs affecting the knees (6.8%) was the most disabling in carrying normal work routines. Working for less than 10 years was significantly associated with high prevalence of WRMSDs in the shoulder (odd ratio (OR) = 0.27, 95% confidence interval (CI) = 0.09 to 0.87) and wrist region (OR = 0.24, 95% CI 0.08 to 0.73). Having neck pain led to higher odds (OR = 0.29, 95% CI 0.13 to 0.68) of taking a break from work among the bricklayers. CONCLUSIONS: WRMSDs were high among Nigerian bricklayers. Years of work experience was associated with high prevalence of WRMSDs in the shoulder and wrist. In addition, taking work breaks was associated with neck pain. Show more

Abstract: BACKGROUND: The easy accessibility of smartphones has led to a fivefold increase in their use. People use smartphones almost anywhere, including during travelling and studying. During the global COVID-19 pandemic, the average smartphone screen time has increased from 2.25 to 4.8 hours per day. In India, smartphone usage increased by 68%, and the average screen time increased from 2.42 to 6.9 hours. This dependency on smartphones has led to smartphone addiction. Inappropriate postures during the prolonged use of smartphones can exert adverse effects such as musculoskeletal disorders, digital eye strain, loss of focus and attention. OBJECTIVES: This study …was undertaken to understand the effects of prolonged smartphone utilisation and explored fatigue measurement techniques. METHODS: A total of 130 studies examining the effects of smartphone utilisation published in the previous 10 years were identified from the following databases: IEEE, Science Direct, PubMed, PubMed Central, and Google Scholar are reviewed. This study was conducted from September 2019 to January 2021. RESULTS: One in every four adolescents were prone to smartphone addiction, which causes poor mental health. Moreover, India’s research on the effects of excessive smartphone usage is limited. CONCLUSIONS: Studies are required to establish the correlation between fatigue levels and smartphone usage patterns. Show more

Abstract: BACKGROUND: Technological progress improves health care efficiency, quality, safety, and cost, supporting clinical activity in various scenarios, such as Intensive Care Unit (ICU). A timely response to alarms from monitors and other ICU electromedical devices is therefore crucial. The number of false alarms tend to desensitize care providers increasing the risk of experiencing alarm fatigue and, at times, lead to severe consequences for patients. OBJECTIVES: To assess the psychometric properties of the Italian version of the Alarm Fatigue Questionnaire and to explore the phenomenon of alarm fatigue among nurses working in intensive care settings. METHODS: …The CVI-I was calculated to evaluate the validity of the content of the tool. Construct validity was investigated through exploratory factor analysis. Cronbach’s alpha coefficient (α) was used to examine the internal consistency of the scale and Spearman’s rho coefficient to test for stability. We designed a multicentre cross-sectional survey. A convenience sample of nurses from 4 Major Italian hospitals was recruited. The nurses completed the Italian version of the Alarm Fatigue Questionnaire. RESULTS: The content validity index CVI-S of the scale (CVI-S) was 91.11%; Cronbach’s alpha coefficient was 0.71. The Italian version of the tool explained 67.18%of the overall variance. 396 nurses were enrolled (79.84%). The overall level of alarm fatigue was Me = 29 [22;30 ]. 42.17%of the sample reported prior experience with alarm fatigue incidents. CONCLUSIONS: The extension of alarm fatigue requires the adoption of a preventive intervention plan. The Italian version of the Alarm Fatigue Questionnaire shows promising psychometric properties.

Abstract: BACKGROUND: Research is needed to gain a deeper understanding of what motivates physicians to do their work and what keeps them in the profession. OBJECTIVES: To explore calling as an approach to work in a sample of physicians. METHODS: We designed an online survey addressing career choice and career calling among physicians in French-speaking Switzerland, and measured associations between calling and categorical variables (participant characteristics, motivations for choosing medicine, career choice(s) and consistency, and definition of calling). RESULTS: The majority of physicians (n  = 229) reported that a calling was not a career motivator. The …main reasons for becoming a physician were to be useful (n  = 173), the scientific aspects of medicine (n  = 168), and altruism (n  = 153). Viewing medicine as a calling was significantly associated with having been attracted specifically and only to the medical career and stability of this career choice. Physicians defined a calling as internal summons (n  = 140), passion (n  = 126), and sense of purpose in life (n  = 101). Being in the right place, internal summons, and passion were significantly more often considered as a definition for calling by physicians with a calling. CONCLUSIONS: A sense of calling influences career choice and professional stability, and might play a protective role in exhaustion or dissatisfaction at work. Show more

Abstract: BACKGROUND: The effectiveness of occupation-based hand therapy and the barriers to the use of occupation-based interventions (OBIs) have been established, but the current experience of hand therapists using OBIs and the extent of the use of OBIs in practice is unknown. OBJECTIVE: This study aimed to identify the frequency that occupational therapists who are Certified Hand Therapists (CHTs) utilized OBIs, how occupational therapists who are CHTs described their application of OBIs, and identify the supports and barriers to the application of OBIs. METHODS: Twenty-nine participants completed a survey that included 27 questions. The questions consisted of …close ended, Likert scale, and multiple-choice questions which were analyzed quantitatively, and open-ended questions which were analyzed qualitatively. RESULTS: The majority of the participants, 57.7%, reported implementing OBI at least 75% of the time. Barriers and supports to the use of OBIs reported include a lack of equipment and therapist creativity, and support for the use of OBIs included the therapist’s creativity, support from the facility, the availability of equipment, and the intrinsic motivation of therapists. Descriptions of OBI application included activity simulation, adaptive equipment use, and participation in meaningful activity. CONCLUSION: Although the use of OBIs in hand therapy may be expanding, occupational therapy practitioners and educators have a role to play in overcoming the remaining barriers to occupation-based hand therapy. Additional research is needed to gain further insight into use of occupation-based intervention by occupational therapists who are CHTs and explore the effect of education on promoting the use of OBIs.

Abstract: BACKGROUND: Manual operations of the hydraulic jack device can become ergonomic stressors for the musculoskeletal system because of the required operational forces, muscle activities, or working postures. However, the usability of the hydraulic jack has not been fully explored for non-professional personnel. OBJECTIVES: To evaluate the musculoskeletal loads during manual operations of a hydraulic jack based on the ergonomic postural analysis and electromyography METHODS: Nine men operated the lever of a hydraulic jack with three positions: parallel to and near (P-N), parallel to and far from (P-F), and orthogonal to the jack lever (O). Postural loads …were evaluated by Loading on the Upper Body Assessment (LUBA), an ergonomic observational method, and were classified into action categories. The surface electromyogram of eight muscles and the subjective sense of burden were also measured. RESULTS: The initial force for lever pushing reached 40–80 N and exceeded the recommended forces for the unusual postures. The overall assessment of LUBA showed that 31% of working postures observed in O position require immediate consideration and corrective action and the maximum holding time estimated was < 1 minute. The postural load increased due to the shoulder joint abduction in the P-F and O positions and due to the trunk rotation in O position. CONCLUSIONS: The results suggest that operating the hydraulic jack cause considerable postural loads and manual forces insufficient for several minutes of manual task. Therefore, improving working methods and tool designs are needed to improve usability and decrease the risk of musculoskeletal disorders during jack operations. Show more

Abstract: BACKGROUND: Due to the rapid growth of metropolises and the insufficiency of public transportation, nowadays, many people travel on these vehicles in a standing position. This position leads to discomfort and the risk of falling or non-collision incidents for the passengers. OBJECTIVE: The present study was conducted to analyze an innovative sit-standing seat to prevent falls and non-collision injuries in standing passengers. METHODS: A total of sixteen participated in this study. EMG signal and Borg scale were used to assess muscle activity and discomfort, respectively. RESULTS: The mean Borg scale score for perceived discomfort …was lower in the sit-standing position than the standing position in all body organs, except for the hips. Also, in the sit-standing position compared to the standing position, the muscle activity of the soleus and medial gastrocnemius muscles was significantly lower in the constant velocity and entire phases in both legs, lower in the right leg in the acceleration phase and lower in the left leg in the deceleration phase. CONCLUSIONS: So, this seat can be used as an innovative idea to improve the ergonomic condition of standing passengers to prevent falls and non-collision injuries on transit buses. Show more

Abstract: BACKGROUND: Exposure to traffic noise could play an important part in inducing psychological disorders which in turn can affect individuals’ cognitive and mental performance. OBJECTIVE: The aim of this study was to determine the effect of traffic noise exposure on the cognitive performance with regard to subjects’ personality traits. METHODS: Sixty students with normal hearing and vision took part in this experimental study. In order to simulate the traffic noise condition of Tehran, the noise from several busy streets was first carefully recorded. Later on, the subjects were exposed to this recorded noise in an anechoic …chamber. Also, the NEO-five factor inventory questionnaire and the continuous performance test were used to assess personality traits and cognitive performance of participants respectively. RESULTS: The results showed that the cognitive features of the study, such as reaction time and the number of commission/omission errors in continuous performance testing increased significantly after exposure to the traffic noise (p  < 0.05), and among the personality traits, only the neuroticism has a significant correlation with response time in the continuous performance tests (p  < 0.05). CONCLUSIONS: Apart from the effect of traffic noise on cognitive function, the findings of this study confirmed that Neuroticism (one of the personality traits) also significantly affect the cognitive performance of individuals when they are exposed to traffic noise in laboratory conditions.

Abstract: BACKGROUND: Nowadays, although the effect of positive safety culture on improving safety performance has been confirmed, the mechanisms of this effect are somewhat ambiguous. OBJECTIVES: This study aimed to investigate the direct and indirect effects of safety culture on safety performance based on a sociotechnical and macroergonomics approach. METHODS: The participants consisted of 276 workers, supervisors, and managers in an oil and gas refinery complex. The data collection conducted using questionnaires including safety culture in accordance with the organization’s sociotechnical characteristics with 12 dimensions (effectiveness of safety management, management’s attitude towards safety, training, awareness and safety …policy, peer support, work schedule, job demands, confrontation of tasks and safety, behavioural features and commitment to safety, work equipment and tools, personal protective equipment, workplace hazards, and external environmental factors), safety motivation and safety knowledge as mediators between safety culture and safety performance, and safety compliance and safety participation as the components of safety performance. RESULTS: The examination of paths in three structural models indicated that in the presence of the direct effect, the indirect paths were not approved due to the lack of confirmation of safety motivation ⟶ safety performance and safety knowledge ⟶ safety performance. In the model without the direct effect, indirect paths were confirmed; however, a low amount of safety performance variance was explained by safety culture. CONCLUSIONS: The safety culture tool explained the highest value of variance for the direct path due to the use of industry-related factors. Show more

Abstract: BACKGROUND: In nursing practice, cognitive failures can be evaluated as an essential indicator of the cognitive capacity of individuals. OBJECTIVES: This study aimed to determine the validity and reliability of the Persian version of the Workplace Cognitive Failures Scale (P-WCFS) among Iranian nurses and its relationship with personality traits. METHODS: Data collection had two phases: 1) The P-WCFS prepared through a standard translation process. Then the content validity was evaluated by a panel of specialists. Reliability Cronbach’s coefficient alpha obtained 0.91 from a pilot study. 2) For measuring neuroticism and conscientiousness used the Goldberg Personality Questionnaire. …Exploratory and confirmatory factors analyzed in two separate parts of the sample (n  = 351). SPSS (v 18) and STATA 14 performed for Statistical analysis. Spearman correlation and Pearson correlation coefficient used to measuring the convergence and examine the relationship between the subscales of the questionnaire. RESULTS: Cronbach’s alpha was 0.92, which showed a high level of reliability for this questionnaire. The three-factor model of WCFS was well-fitted. The reliability of all three sub-scales was a reasonable level. Cognitive failures and its subscales had negative and strong relationships with conscientiousness and neuroticism. The highest internal consistency was related to memory subscale, and all scales had a success rate of 100%. CONCLUSIONS: This study showed the P-WCFS has high reliability and validity and can be used in nursing society. Show more

Abstract: BACKGROUND: Low back pain (LBP) is the most common musculoskeletal disorder work-related health problem in Europe, affecting millions of workers. It is estimated that 60–80% of the population will suffer at least one episode of mechanical LBP during their life. OBJECTIVE: To evaluate the kinesiotape (KT) effectiveness in mechanical LBP. METHODS: This was a double blinded, randomized-controlled clinical trial. Twenty-eight nursing and cleaning auxiliaries from Salamanca received a manual therapy program and a bandage of KT or false kinesiotape (FKT). They received two sessions a week for three weeks and a follow-up one month after the …last session. Pain, range of motion and function were measured at baseline, at the end of each session and a month after the last session. RESULTS: Work-related musculoskeletal disorders and LBP are responsible for a high prevalence of sick-leave and absenteeism. Manual therapy and KT has demonstrated to reduce pain and to increase range of motion and function being effective in this population. There are statistically significant results in both groups in all measurements for all variables. KT seems to be superior, however, both have a positive effect on LBP. Although benefits decrease, long-term treatments focusing on pain alleviation and functional recovery is needed to maintain the benefits achieved. CONCLUSION: KT was an effective complement for this treatment. Although both show improvements, KT is recommended. Future studies are needed to demonstrate KT properties, to establish a treatment protocol to prevent chronic LBP and to avoid sick leave and absenteeism. Show more

Abstract: BACKGROUND: Sleep disturbance including insomnia and poor sleep quality has been shown to be a major health determinant in occupational settings. Specific occupational exposures to hazards in most workplaces can lead to various health problems, especially sleep problems. OBJECTIVE: The study aimed to investigate sleep characteristics, and their relationships with work-related exposures, demographics, and other related variables in workers of a smelting factory. METHODS: This cross-sectional study was carried out on workers in a 40-year smelting factory located in the East of Tehran Province. A total of 200 male participants were included in the study. Among …them, 51 workers were from the production process staff and the rest were office workers. Their shifts were from 6 AM to 5 PM. All participants were asked about demographic characteristics and exposure to respiratory pollutants. All participants answered validated Persian versions of the Insomnia Severity Index (ISI) and the Pittsburgh Sleep Quality Index (PSQI). RESULTS: The means (SD) of age and BMI were 39.1 (8.9) years and 26.8 (4.5) kg/m2, respectively. Among all participants, 51 (25.5%) experienced exposure to a respiratory pollutant. Among all workers, 96 (48%) experienced poor sleep quality and 87 (43.5%) and 10 (5%) had subthreshold and clinical insomnia, respectively. The mean (SD) night sleep duration was 6.4 (0.96) hours. Data analysis illustrated a significant positive relationship between exposure to respiratory pollutants and insomnia (p -value = 0.03). Howewer, this association between sleep quality and exposure to repiratory pollutants was not significant (p -value = 0.25). Further analysis with binominal regression showed participants with exposure to respiratory pollutants were more susceptible to clinical insomnia (p- value = 0.02, exp(B) = 0.213), and after regressing out the effect of smoking, participants with exposure to respiratory pollutants remained susceptible to clinical insomnia. A lower night sleep duration was observed among participants with exposure to inhalational material (p -value = 0.05). CONCLUSIONS: Occupational exposures to hazardous material, including inhalational exposures, could cause sleep disturbance, which warrants more attention paid by sleep specialists. Show more

Abstract: BACKGROUND: The Oswestry Disability Index (ODI) is a common outcome-measure used for assessment of spinal disorders with three officially updated versions. However, there are recently published articles that still use ODI-1.0. This suggests the existence of a block on information flow between developers and end-users. OBJECTIVE: To investigate the articles with missing citation to the latest ODI version, to calculate the life span of previous ODI version and to investigate the existence of a block on information flow. METHODS: PMC-PubMed citation dataset is analyzed by CNA and text processing methods. RESULTS: The most important …finding of this study is that there is no block on information flow between developers and users in terms of visibility in citations and full text access restrictions. Three different sub-networks are identified between ODI-1.0 and ODI-2.0 articles. 14% (165) of articles have citation to ODI-1.0 and ODI-2.0 version-articles. The time limit that is required for the new ODI version to become dominant in the literature is between 4 and 9 years. CONCLUSION: There is a missing citation problem in the ODI literature which is not a result of a block on information flow between developers and end-users. Show more

Abstract: BACKGROUND: The aging of the workforce is changing, but working conditions have not changed at the same exponential growth rate for senior workers. Such a situation can compromise the worker’s physical and cognitive capability, reducing the ability to perform work activities. OBJECTIVES: This study aims to understand the main functional capacity changes in senior workers in the automotive industry and to determine the contribution of working conditions on the decline of the functional capacity in senior workers. METHODS: To achieve the objectives of the study, a set of questionnaires (Sociodemographic Data, COPSOQ, Nordic Questionnaire, and Par-Q) …and a battery of 4 functional capacity tests were used. Results: Work conditions, namely awkward postures, force demands and manual material handling, and age, were statistically associated to the functional decline in workers. Additionally, multiple linear regression showed that height, weight, seniority, and strength have predictive value to the handgrip decline (both positions HG2 and HG5). CONCLUSION: These results suggest that workers’ handgrip assessment should be considered as a future measure as an indicator of strength ability in the occupational field. Show more

Abstract: BACKGROUND: Call center workers are highly susceptible to work-related musculoskeletal disorders (WRMSDs) as well as mental stress. Nonetheless, there has been a surprising paucity in the body of the research regarding interventions among call center workers. OBJECTIVE: The purpose of this paper is to investigate the effectiveness of a multicomponent ergonomic intervention program on mental workload, mental fatigue and WRMSDs of call center employees. METHOD: A non-randomized interventional study with a single group pretest-posttest design was conducted among 84 call center workers of a private telecommunication company in the city of Tehran, Iran. At the baseline, …data regarding WRMSDs prevalence, mental workload and mental fatigue were collected by means of standard Nordic, NASA-TLX and SOFI questionnaires, respectively. Then, subjects participated in a multifaceted intervention program including comprehensive office ergonomic training, work layout improvement, supervised on-site face to face visits, and provision of quality break time encompassing regular exercise program. Follow-up assessment was carried out after 6 months. RESULTS: After the intervention, prevalence of WMSDs in the neck (10%, P  = 0.022), lower back (8.4%, P  = 0.04), and knees (9.5%, P  = 0.02) decreased significantly, while improvements in other body areas remained insignificant. Results also showed a significant decrease in overall score of mental demand (P  = 0.000) as well as three of its subscales including performance (P  = 0.02), effort (P  = 0.001), and frustration (P  = 0.025). Additionally, positive effect of the intervention was also observable on overall mental fatigue of call center workers (P  = 0.016). As for its subscales, Lack of energy was reported to decrease meaningfully (P  = 0.007) while lack of motivation did not change significantly (P  = 0.240). CONCLUSION: Although the primary focus of many ergonomic interventions has remained to measure physical outcomes of the work place, our findings show that multicomponent interventions are indeed capable of boosting cognitive aspects of the work as well. The future studies should consider investigating such outcomes. Show more

Abstract: BACKGROUND: Across the global landscape, mental health care still exhibits challenges because of the lack of human and professional resources to face its consequences. In Morocco, mental health problems affect mainly adolescents and young adults, with a clear impact on functional engagement in their daily lives. Occupational therapy, as a holistic and person-centered practice, may be an ideal mental health strategy to promote health and well-being through occupation, thereby enabling individuals to participate in regular daily activities. OBJECTIVE: To understand, from an intercultural perspective, the point of view of mental health professionals regarding the role and importance of …occupation-based practices in Errazi Mental Health Hospital in Salé(Rabat) Morocco. METHOD: A qualitative research design was used for this study. Data collection consisted of semi-structured interviews with 12 mental health care professionals (non-occupational therapists). These results were used to gain an understanding of their perspectives regarding the main role of human occupation in mental health services in Morocco, and to incorporate an intercultural outlook in terms of occupational therapy. Data analysis was conducted in three phases, by following the grounded theory methodology. RESULTS: Two categories, “dimensions of occupation in Moroccan mental health ” and “the interplay between traditional and western perspectives involving mental health ” emerged from this research. Both categories included five subcategories. CONCLUSION: This study identifies how occupation-based services in Moroccan mental health care require considering not only the cultural perspective of mental health, and the sociocultural meaning rooted in occupations, but also the relevance of incorporating a community-centered approach. Moreover, it discusses how occupational therapy education in Morocco must incorporate an intercultural perspective of the therapy’s theory and practice. Show more
